What is a flange? A thorough explanation by professionals from types and standards to gasket selection.

What is a flange? A thorough explanation by professionals from types and standards to gasket selection.

This article explains the basic structure of flange joints and thoroughly compares the five main types, including their applications, advantages, and disadvantages!

"Leaks from the piping won't stop," "I don't know which flange or gasket to choose," "I'm struggling with the balance between cost and safety." Piping systems support factories, plants, and social infrastructure. The key to their stable operation lies in the "flanges" that connect pipes and equipment. While they may seem like simple components at first glance, choosing the wrong one can lead to production stoppages, environmental pollution, and even serious accidents. This article comprehensively explains everything from the basic knowledge of flanges to practical selection points for all individuals involved in the design and maintenance of piping systems, including engineers and purchasing personnel. You will learn about the differences in types and standards, the seat shape that affects sealing performance, and most importantly, how to select the right gasket. By reading this article, you will understand it all. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.*

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. For further inquiries, please feel free to contact us.

Custom processing and selection of gaskets in this one book.

Custom processing and selection of gaskets in this one book.

Torque specification table and manufacturer comparison table included! Comprehensive catalog [with technical data].

"I want a large-diameter gasket that is not a standard product." "I want a one-off item precisely processed from the drawing." "I want to quickly confirm the tightening torque for the JIS flange needed for construction." "It takes time to find equivalent products from Nichias or Vulcan." These requests for "custom processing" and the concerns about "selecting standard products." At Daiko, a specialized manufacturer of gaskets and packing, both can be resolved with this one comprehensive catalog. Our company is a processing manufacturer of industrial products with over 50 years of experience. We go beyond mere product sales and respond to various challenges faced by our customers with our technical expertise. *For detailed content of the column, please refer to the related links.

Selection of gaskets for exhaust ducts, incinerators, and dryers.

Selection of gaskets for exhaust ducts, incinerators, and dryers.

A unique book from a specialized manufacturer! We have prepared a maintenance catalog for exhaust systems.

"The manhole packing of the incinerator deteriorates quickly at high temperatures." "I can't find a large-diameter gasket that fits the corner flange of the exhaust duct." "For the hot air line of the dryer, I don't need high airtightness, but I want a sealing material that is heat-resistant." Are you struggling to address the sealing and insulation challenges unique to high-temperature, low-pressure exhaust systems with general-purpose gaskets like joint sheets? Maintenance of high-temperature hot air and exhaust lines requires specialized properties such as "heat resistance," "flexibility," and "workability." To solve these issues, Daiko Co., Ltd., a specialized manufacturer of industrial gaskets, has prepared a free PDF catalog focused on the maintenance of high-temperature equipment such as exhaust systems, boilers, and dryers. *For more details on the column, please refer to the related links. Feel free to contact us for more information.

[Production Example] D1000 Spiral Type Gasket for Boilers

[Production Example] D1000 Spiral Type Gasket for Boilers

We can also manufacture spiral gaskets with special shapes based on your drawings and specifications!

We would like to introduce a case where we manufactured a D1000 spiral gasket (thickness 4.5mm) for an oval opening (300mm×400mm, seal width 25mm) based on the customer's drawing. It prevents leaks of high-temperature and high-pressure steam or hot water. In this case, we produced a V-shaped cross-section metal hoop and filler, which is the sealing material, with high precision using a dedicated winding machine. The spiral gasket is a high-performance semi-metallic gasket that is rationally designed for high temperature and high pressure applications. We can also manufacture spiral gaskets with special shapes based on the customer's drawings and specifications. Please feel free to contact us. 【Case Overview (Partial)】 ■ Material: D1000 ■ Product: Spiral gasket ■ Shape: Oval (300mm×400mm, seal width 25mm) *For more details, please download the PDF or feel free to contact us.

[Precision Cutting Processing Example] Special Gasket Made of Fluororesin

[Precision Cutting Processing Example] Special Gasket Made of Fluororesin

Even for resin products with low dimensional stability! Proposals to enhance dimensional accuracy through processes like annealing.

We would like to introduce a case study of precision machining of "special gaskets made of fluororesin" conducted by our company. To allow chemicals to pass through the evenly drilled fine holes, we use fluororesin, which is not affected by various fluids (liquids and gases) such as general chemical agents and solvents. Additionally, since the dimensional stability of fluororesin is low during machining, the usual tolerance is about ±0.1. However, by performing annealing treatment, it is possible to reduce the tolerance to about ±0.05. 【Case Overview】 ■ Name: Special Gasket Made of Fluororesin ■ Material: Fluororesin ■ Dimensions: Outer diameter φ100 × Inner diameter φ75, Hole φ1.5 × 120 pieces ■ Precision: ±0.05 ■ Features: Surface annealing treatment *For more details, please refer to the related links or feel free to contact us.

Epoxy foam resin

Epoxy foam resin

Developed an epoxy resin formulation that foams and cures upon heating!

We have developed an epoxy resin formulation that expands and hardens through heating, and we handle a sheeted version (B-Stage) of this "epoxy foam resin." It can be used alone, but when forming composite materials, it can be molded and foamed all at once. This eliminates the need for the molding, polishing, and bonding processes of conventional foaming materials, leading to a reduction in processing time. 【Advantages】 ■ Can be combined with composite materials for one-step molding ■ Can be applied to surfaces such as the top and sides ■ Foam thickness (amount of foaming) can be adjusted by layering ■ Easy to cut to fit shapes ■ Easy to manage usage amounts *For more details, please download the PDF or contact us.
