Solving the "troubles" of gasket selection! Fluid compatibility chart (chemical resistance list)

Solving the "troubles" of gasket selection! Fluid compatibility chart (chemical resistance list)

We have prepared a fluid compatibility chart (chemical resistance list) with a manufacturer comparison table!

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.

[Bonding Processing Example] EPDM Rubber + PTFE Laminated Gasket

No delamination in bonded materials of different types! A case study of high-precision cutting with a water jet.

We would like to introduce a processing case where a large product measuring 310mm × 1466mm was created from a special material made by bonding a PTFE sheet to an EPDM rubber block with a thickness of 55mm. This product is a high-performance composite that combines the elasticity and weather resistance of EPDM rubber with the chemical resistance and slip properties of PTFE. The part in contact with liquids is made of PTFE, which is strong against chemicals, while the main body is made of EPDM, providing a solid elastic sealing function. Using our water jet cutting machine, we achieved high-precision cutting of bonded materials with different hardness levels without delaminating the adhesive surfaces. [Case Overview] ■ Processing Details: Drilling a hole with a diameter of 194mm and chamfering the corners with C15 ■ Material: Laminated product of EPDM (55t) + PTFE (1t) *For more details, please download the PDF or feel free to contact us.

Causes of Axial Force Reduction and Behavior by Material Type [Technical Explanation]

Causes of Axial Force Reduction and Behavior by Material Type [Technical Explanation]

Explaining the mechanism of "stress relaxation" in gaskets and tightening management!

"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.

Mechanisms of "Thermal Degradation" and "Crazing"【Technical Explanation】

Mechanisms of "Thermal Degradation" and "Crazing"【Technical Explanation】

An explanation of the risks of "over-tightening" that should never be done, based on technical materials from Nichias!

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.

What is the true power of the stainless steel absolute champion "SUS304"?

What is the true power of the stainless steel absolute champion "SUS304"?

Necessary and sufficient "corrosion resistance," excellent "workability and weldability," overwhelming "distribution volume and cost"! A thorough dissection from features to differences with SUS316.

SUS304 is so widely used, from everyday items to industrial equipment, that it is often referred to as "the representative of stainless steel." From household items like spoons and forks to building exteriors and piping in chemical plants, why is SUS304 continuously chosen? The reason is simply that "the balance between performance and cost is extremely good." In this article, we will explain the "three strengths" of SUS304 and the decisive differences between it and the higher-grade SUS316. *For more detailed information, please refer to the related links.
