In the design and maintenance of piping for plants and equipment, gasket selection is extremely important yet one of the most challenging tasks. In particular, confirming compatibility with "fluids" (chemical resistance) is the first hurdle in the selection process. The types of fluids vary widely, including water, oil, gas, and corrosive fluids (acids and alkalis). If the selection is incorrect, there is a risk of serious accidents or production stoppages due to leaks. To solve the "problems" faced by busy design and maintenance personnel, Daiko Co., Ltd., a gasket expert, has prepared a truly useful "Fluid Compatibility Table" as a free white paper (PDF document) for the field. *For more details on the column, you can view it through the related links.

Leakage from gaskets in plant and factory piping flanges is a serious issue that directly leads to production stoppages, energy losses, and significant safety accidents. Many of these troubles are caused by "inadequate management of tightening force," that is, poor construction. In this article, we will explain why "torque management" is essential for gasket sealing, the fundamental theory behind it, and an overview of the three common types of tightening failures (insufficient, excessive, and uneven tightening) along with their examples and countermeasures. *For detailed content of the column, please refer to the related links. Feel free to contact us for more information.*

In the industrial sector, there are extreme high-temperature and high-pressure areas that cannot be reached with composites made of rubber, resin, or non-metals, such as plants, offshore facilities, and pressure vessels. To contain fluids with absolute reliability under such harsh conditions, the "metal gasket," composed entirely of metal, was designed, with the "ring joint gasket" being a representative example. In this article, based on the official product documentation from Vulcan, we will thoroughly explain why ring joint gaskets exhibit high sealing performance, the secrets of their structure, the differences between the two important shapes, "octagonal" and "oval," and the correct material selection and usage to fully utilize their capabilities. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.

"Rubber gaskets and packing" support the performance and safety of equipment. However, even when grouped under "rubber," there are many types, each possessing completely different characteristics (such as oil resistance, weather resistance, heat resistance, etc.). If this selection is incorrect, it can lead to serious issues such as "rubber swelling due to oil" or "cracking due to ozone." In this article, we will compare and explain the characteristics of nine major types of rubber materials, providing the foundation for a "selection guide" to help you choose the right product for your application. *For more detailed information, please refer to the related links.

In plant, factory, and building construction, the greatest enemy of insulation materials is "water." Fiber-based insulation materials such as rock wool and glass wool experience a rapid increase in thermal conductivity once their air layers are replaced by water, resulting in a near-total loss of their insulating function. To address this fundamental issue in outdoor and humid environments, Nichias Corporation has developed the "MG Hassui Board." This high-performance product retains the excellent basic performance of Nichias's renowned rock wool insulation material, "MG Board," while adding powerful "water-repellent performance." In this article, based on Nichias Corporation's official product catalog, we will thoroughly explain why the MG Hassui Board is chosen as an insulation and sound absorption solution for outdoor equipment and humid environments, from the core of its performance to the critical temperature limit of "150°C" that you must absolutely know when selecting it. *For detailed content of the column, please refer to the related links.

"I want to reduce heat loss from the factory boiler." "I want to do something about the noise in the machinery room." "I want to use safe, non-combustible, and insulating materials in the building's ducts and partition walls." From plants and factories to building construction and general housing, "insulation (energy saving)," "sound absorption (soundproofing)," and "fire resistance (safety)" are extremely important issues that cannot be overlooked in modern facilities and architecture. The high-performance rock wool insulation material "MG Board" provided by Nichias Corporation meets these diverse demands at a high level with a single material. *For more details on the column, please refer to the related link. For more information, feel free to contact us.

In insulation and soundproofing work for plants and factory equipment, the material's "thermal insulation performance" and "sound absorption performance," along with "ease of installation" and "shape retention (durability) after installation," become extremely important. In particular, for complex shapes and vertical surfaces, such as the walls of boilers exposed to high temperatures and the heads of large tanks, the fixation and retention of insulation materials have been long-standing challenges. To meet the conflicting demands of "high-performance insulation" and "reliable workability and durability," Nichias Corporation has developed the "MG Rass Board," which is a high-performance rock wool insulation material reinforced with metal. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.*

In plant and building construction, the insulation of equipment with "curved surfaces," such as piping, air ducts, and tanks, has always been a challenge for contractors. If flat board insulation materials are forcibly bent during installation, cracks and gaps (heat bridges) can occur, significantly reducing insulation performance. On the other hand, blanket rolls can sometimes make it difficult to maintain the shape during installation. To meet these seemingly contradictory demands of "perfect conformity to curved surfaces" and "ease of installation," Nichias Corporation has developed a high-performance rock wool insulation material called "MG Belt" using its unique technology. *For more details on the column, please refer to the related links.

In selecting waterproof sealants, cushioning materials, and packing materials, there are surprisingly few materials that meet the three elements of "water-stopping ability," "flame resistance," and "weather resistance" at a high level. The reality is that common sponges often have trade-offs, such as "stops water but is flammable" or "flame-resistant but has weak weather resistance." In response to these challenges, the chloroprene rubber (CR) sponge "Gum Sponge C-4305," manufactured by Inoac Corporation, has been chosen as a standard in the industry for many years. In this article, based on the manufacturer's official technical documentation and product characteristics, we will thoroughly explain why C-4305 has gained such trust from many engineers and designers who say, "You can rely on C-4305 for now." We will delve into the secrets of its core performance, including its "closed-cell structure" and "flame-retardant CR formulation," specific applications, and the "processing technology" that allows this material to be shaped flexibly to meet on-site needs. *For detailed content of the column, you can view it through the related links.

In plant and building piping systems, "corrosion" is the greatest risk factor that shortens the lifespan of equipment and can lead to serious accidents. Among these, "galvanic corrosion" (dissimilar metal contact corrosion) that occurs when different metals are connected progresses rapidly and is a phenomenon for which countermeasures are essential. The standard method to prevent this galvanic corrosion is the use of "insulation kits" (insulation bolts and gaskets). Among these, the "insulation lining bolt," which has the bolt shaft coated with fluororesin, is particularly excellent in terms of workability and reliability, and can resolve installation issues on-site (such as interference with gaskets). This article will thoroughly explain the mechanism of why "galvanic corrosion" occurs, why insulation lining bolts are supported on-site, their structural advantages and specifications, and the appropriate selection methods tailored to on-site standards. *For detailed content of the column, please refer to the related links.

The challenges of "cutting processing" in manufacturing sites always lie in balancing "cost," "delivery time," and "accuracy." While dedicated mold presses offer high precision, they come with high initial costs and long lead times. On the other hand, hand cutting and cutting plotters have no initial costs, but they tend to have longer takt times during mass production, resulting in higher unit prices. A suitable solution to this dilemma is the long-established technique known as "Thompson processing (die cutting)." This article will thoroughly explain the basics of Thompson processing, why Daiko is committed to "in-house mold production," its technical advantages, and its ability to handle a wide variety of materials such as joint sheets, rubber, sponge, and PTFE. *For detailed content of the column, you can view it through the related links.

In manufacturing environments where "hygiene management" is the top priority, such as in food, beverages, pharmaceuticals, and cosmetics, the selection of rubber components (gaskets, seals) used is extremely important. This is because it is not only about preventing leaks but also about ensuring safety for the human body (compliance with regulations) and significantly reducing the risk of foreign material contamination. A suitable solution to meet such stringent requirements is the "EP-5165-W" developed by Iruma River Rubber Co., Ltd. This is a special grade of white (white) EPDM (ethylene propylene rubber) that is compliant with food hygiene laws and excels in weather resistance and chemical resistance. In this article, we will thoroughly explain why EP-5165-W continues to be chosen in hygiene management settings from the perspectives of "legal compliance," "color advantages," and "basic performance," and we will introduce our solutions at Daiko Co., Ltd., which process and supply this safe material tailored to the shape of our customers' equipment, starting from just one piece. *For detailed content of the column, please refer to the related link.

In the manufacturing environment of products that enter the human mouth, such as food, beverages, pharmaceuticals, and cosmetics, the safety of "rubber packings" and "gaskets" used in equipment is as important, if not more so, than the safety of the products themselves. If harmful substances were to leach from the rubber and contaminate the products, the trust in the company would collapse instantly. Not an ambiguous "food grade," but truly safe silicone rubber based on "solid evidence" from a public testing organization. That is the "Silicone Rubber Sheet SN-50" from Osaka Rubber Co., Ltd. In this article, we will thoroughly explain why SN-50 has gained absolute trust in the food and medical fields, based on the test report (No. 452-21-A-0055) issued by the Chemical Substance Evaluation and Research Institute (CERI), detailing its legal basis and test results. *For detailed content of the column, please refer to the related links.

In the manufacturing fields of food, pharmaceuticals, and cosmetics, achieving a balance between "safety (compliance with the Food Sanitation Act)" and "durability (heat and chemical resistance)" is an eternal challenge. While silicone rubber and EPDM are safe and easy to use, they may not withstand high-temperature oils, certain chemicals, or high-pressure steam. This is where "Food Sanitation Act-compliant fluorine rubber IF-900," proudly offered by Iruma River Rubber Co., Ltd., comes into play. IF-900 is a high-grade product that maintains the inherent heat and oil resistance of fluorine rubber while complying with the Food Sanitation Act (Ministry of Health and Welfare Notification No. 370). In this article, we will provide a detailed explanation of the physical properties and resistance data of IF-900 based on the manufacturer's official catalog. We will also introduce our processing solutions at Daiko Co., Ltd. to procure this expensive material in the necessary shapes and quantities without waste. *For more detailed content of the column, please refer to the related links.

The "sheet gasket," which is the most familiar sealing material on site, is widely used due to its convenience of being processed with scissors or cutters, such as joint sheets and fluororesin sheets. However, when it comes to its "thickness," are you not deciding it based on a vague feeling? In fact, the belief that "thicker is stronger and safer" for sheet gaskets is a significant misconception. On the contrary, it is not uncommon for overly thick selections of sheet gaskets to cause critical leakage problems precisely because they are sheet gaskets. In this article, we will thoroughly explain why "thin" is recommended for sheet gaskets, as well as the situations where "thick" is necessary, and the criteria for selection. *For detailed content of the column, please refer to the related links. For more information, feel free to download the PDF or contact us.*

"A leak occurred from a flange that was supposed to be tightened to the specified torque a few months later." "After performing a re-tightening (hot bolting), the gasket was damaged." Such troubles are not uncommon in the maintenance of plants and piping systems. The main cause cited is the physical phenomenon specific to gaskets known as "stress relaxation." This article will explain the mechanism of stress relaxation, the differences in behavior depending on the material, and appropriate management methods to maintain long-term sealing performance. *For detailed content of the column, you can view it through the related link. For more information, please download the PDF or feel free to contact us.*

Have you ever been troubled by such inexplicable minor leaks at the piping site? It may not be "interface leakage" that leaks from the gap between the gasket and the flange, but rather "permeation leakage," which leaks through the material of the gasket itself. In particular, when using "sheet gaskets" such as joint sheets, the risk of this permeation leakage is always present. The most effective countermeasure for this is to "make the gasket thinner." In this article, we will explain the often-overlooked mechanism of "permeation leakage" and the physical reasons why thick gaskets can lead to leaks. *For more detailed information, you can view the related links. For further details, please download the PDF or feel free to contact us.*

"Even after tightening, it keeps dripping from the gap between the flange and the gasket." "When I reused old piping, even though I put in a new packing, it won't stop." "There is rust and scratches on the flange surface, but there is no budget for replacement." The most frequently encountered trouble in piping maintenance is "Interface Leakage." Unlike "permeation leakage," which passes through the material of the gasket itself, this phenomenon occurs when fluid escapes through the "gap" between the gasket and the flange surface. The key to stopping interface leakage is "familiarity." In this article, we will explain why interface leakage occurs and how to approach rough flanges to stop the leakage. *For more detailed content of the column, please refer to the related link.

In the field of plant maintenance, issues with steam line leaks are never-ending. Many of these problems stem from a "selection mistake" where "joint sheets for general piping (water and oil)" were carelessly used in steam piping. "I thought it would be fine because the catalog said it was heat-resistant up to 150°C." This complacency can be fatal. There are clear physical reasons why only "steam-specific" materials should be used for steam piping. This article will explain the mechanism of "thermal degradation (hardening)" that occurs when the wrong gasket is used, as well as the risks of "re-tightening," which should absolutely be avoided, based on technical materials from Nichias. *For detailed content of the column, please refer to the related links.

"I want to reduce the particles (micro-particles) in the chemical solution to the absolute minimum." "I want to shorten the piping cleaning (flushing) time and speed up the startup." "Since we use harsh chemical solutions, we need high durability." In the fields of semiconductor and LCD manufacturing, where nano-level precision processing is required, the specifications demanded for piping tubes are becoming increasingly stringent each year. The "TOMBO No.9003-PFA-HG Naflon PFA-HG tube" from Nichias meets these advanced requirements that are difficult to achieve with standard PFA tubes. We will unravel why it is labeled "HG (High Grade)" and its overwhelming specifications. *For detailed content of the column, please refer to the related link.
