Daiko high-temperature sleeve packing "D-2000" boiler component!

Daiko high-temperature sleeve packing "D-2000" boiler component!

D-2000 High-Temperature Sleeve Packing Compared to conventional non-asbestos sleeve packing materials, it offers superior durability.

Daiko's high-temperature sleeve packing "D-2000" for boilers is a high-temperature sleeve packing made from chemically stable graphite, which has excellent heat resistance. It resolves the heat resistance issues that were problematic in conventional non-asbestos sheets primarily composed of synthetic rubber under high-temperature steam conditions. Additionally, it is reinforced with a small amount of high-strength fibers, offering great flexibility and moderate surface hardness, making it resistant to scratches during handling. We also offer a graphite-filled Teflon material called "D-2000-G." 【Features】 <D-2000> ■ Excellent heat resistance ■ Based on chemically stable graphite ■ Highly flexible with moderate surface hardness *For more details, please refer to the PDF document or feel free to contact us.

Daiko's expansion graphite gasket "D-4000"

Daiko's expansion graphite gasket "D-4000"

Expanded graphite is a material obtained by treating high-purity graphite crystals with chemicals and then heat-treating them at high temperatures. It can be used over a wide range from high temperatures to extremely low temperatures.

The Daiko D-4000 is a non-asbestos joint sheet that can cover the practical temperature range of asbestos joint sheets (up to 400°C). Expanded graphite is a material obtained by treating high-purity graphite crystals with chemical agents and then heat-treating them at high temperatures. By incorporating stainless steel plates (SUS316) as a core material, it creates a gasket with excellent mechanical strength. It has a heat resistance level comparable to that of asbestos sheets and possesses excellent corrosion resistance. The D-4000 is a gasket material that has a long-standing excellent track record in Europe, where non-asbestos technology has advanced, and can be used widely from high temperatures to extremely low temperatures. It can be used for gaskets in various piping flanges, valves, equipment, pumps, pressure vessels, heat exchangers, condensers, and more. 【Features】 ■ Sealing and chemical resistance comparable to asbestos joint sheets ■ Excellent corrosion resistance ■ Wide temperature range from high to extremely low temperatures ■ Excellent compressibility *For more details, please refer to the PDF document or feel free to contact us.

Gasket Packing Q&A No. 1

Gasket Packing Q&A No. 1

We will answer your questions about the reuse of gaskets!

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. "Is it possible to reuse a gasket that has been used once?" → Reuse is not recommended regardless of the usage period or type. Although flanges may appear smooth at first glance, they have microscopic irregularities. A gasket that has been used once deforms to fit the contours of the flange. If this deformed gasket is reused, gaps may form between the flange and the gasket, leading to the possibility of leaks. *For more details, please refer to the PDF document or feel free to contact us.

Gasket Packing Q&A No. 3

Gasket Packing Q&A No. 3

I will answer your questions about the differences between SUS316 and SUS316L!

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. "What is the difference between SUS316 and SUS316L?" → There is a difference in workability. SUS316L is a stainless steel that is easier to process than SUS316. SUS316 contains a higher amount of hard metals (Cr, Ni), making it difficult to work with, but by lowering the carbon content, it becomes slightly softer and easier to process. (The "L" stands for low carbon.) The main difference is the carbon (C) content, with SUS316L having "0.03% or less," which falls under the "0.08% or less" of SUS316. *For more details, please refer to the PDF document or feel free to contact us.

Gasket Packing Q&A No. 6

Gasket Packing Q&A No. 6

Is there a material that can improve the creep phenomenon of Teflon?

Daiko Corporation will answer your questions regarding gaskets and packing. 〇 Creep Phenomenon It is known that fluoropolymer-based gaskets experience significant decreases in bolt axial force due to creep relaxation characteristics. This reduction in bolt axial force raises concerns about sealing performance, and the risk of leakage accidents increases due to internal pressure loads and external forces from earthquakes, making it necessary to properly manage bolt axial force through re-tightening. 〇 Countermeasure Products We offer gaskets that improve creep resistance by mixing PTFE with special inorganic fillers that have corrosion and heat resistance, suitable for use up to 200°C. Representative products include Vulcan's V7020 and Nichias's T9007LC. They are resistant to almost all fluids except for hydrofluoric acid and strong alkalis. We have stock in sheet form and can process it to your specified dimensions.

Gasket Packing Q&A No. 8 Measures Against Gasket Penetration Leakage

Gasket Packing Q&A No. 8 Measures Against Gasket Penetration Leakage

I want to prevent gas leaks from the joint sheet! I will propose measures against gasket permeation leaks!

◆Issue Details 　　〇When using the joint sheet as a gasket and conducting a leak test, the leakage does not stop. ◆Possible Factors 　　〇The gasket shape is FF type → Insufficient surface pressure 　　〇No paste applied → Gas permeates 　　〇Thickness is 3.0 mm → Gas is prone to permeation, significant stress relaxation ◆Countermeasures 　　〇Change the gasket shape to ring type (inner packing) 　　〇Apply gasket paste to the flange contact surface and inner diameter end face 　　〇Reduce gasket thickness to 1.5 mm (especially for smaller sizes, below 200A)
