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.

Deformation prevention: Rubber sponge and packing - No need for replacement due to deformation!

Deformation prevention: Rubber sponge and packing - No need for replacement due to deformation!

Countermeasures for sponge rubber packing wear! High resilience sponge packing that can almost eliminate wear even with long-term use over a decade.

High-recovery ethylene propylene diene monomer (EPDM) rubber, when used as airtight seals for equipment handling powders or waterproof seals for liquids, exhibits extremely low compression deformation even after prolonged use, ensuring that the seals do not "sag." By utilizing this feature, it becomes possible to significantly reduce the frequency of seal replacements in hard-to-maintain areas deep within machinery. As a material, EPDM excels in chemical resistance, cold resistance, ozone resistance, and aging resistance. Its inherent elasticity as sponge rubber, combined with its non-sagging characteristics and consistent load response, allows it to also be used as "damping material." High-recovery rubber sponge has extremely low permanent deformation, providing excellent shape retention, and it instantly returns to its original form even after being subjected to prolonged pressure. - Features - - High weather resistance due to EPDM (ethylene propylene rubber) - Operating temperature range: -20 to +80°C - Sulfur-free grade with free sulfur below measurement limit - Flame retardant/oil-resistant grade (railway flame retardant compliant) * Custom cutting to required lengths available, with adhesive tape for delivery - Instantly recovers from a compressed state - High shape retention - Extremely low permanent deformation - Soft sponge suitable for a wide range of applications

Sponge packing wear prevention measures

Sponge packing wear prevention measures

Are you experiencing issues with water sealing or airtightness due to the wear of sponge rubber packing? There is almost no wear even after long-term use (10 years)!

This is a sponge rubber made of EPDM with the added feature of high resilience that does not deform easily. When used as airtight seals for equipment handling powders or waterproof seals for liquids, it exhibits extremely low compression deformation even over long periods, preventing the seals from wearing out. For example, it significantly reduces the frequency of seal replacements in areas with poor maintenance accessibility. By incorporating the inherent chemical resistance, cold resistance, ozone resistance, and aging resistance of EPDM, along with the "non-deforming" characteristic of sponge rubber, it eliminates the need for replacements due to wear. Additionally, by further developing this concept, it can also be utilized as a "damping material" by leveraging its consistent load response. - Features - - High weather resistance with EPDM (ethylene propylene rubber) - Operating temperature range: -20 to +80°C - Sulfur-free grade with free sulfur below measurement limits - Flame retardant/oil resistant grade (railway flame retardant compliant) * Custom cutting to required lengths available, with adhesive tape for delivery - Instant recovery from a compressed state - High shape retention - Extremely low permanent deformation - Soft sponge suitable for a wide range of applications

Sealing-less: A durable rubber packing that enables caulking-less applications.

Sealing-less: A durable rubber packing that enables caulking-less applications.

Are you having problems with water sealing using caulking (sealing)? By replacing caulking with a durable rubber packing, you can achieve quantitative water sealing!

Is there a decrease in water-stopping functionality due to a shortage of craftsmen or lack of experience in caulking, leading to water-stopping complaints? We propose the possibility of achieving caulking-free solutions by converting part of the on-site caulking to rubber packing. Additionally, by using sponge rubber that incorporates a high resilience feature of "not deforming," we can significantly reduce the frequency of caulking reapplication. The EPDM, which is the raw material for rubber sponge, possesses excellent chemical resistance, cold resistance, ozone resistance, and aging resistance. By adding the characteristic of "not deforming" to the inherent elasticity of sponge rubber, it eliminates the need for replacement due to deformation. Furthermore, by developing this concept, it can also be utilized as a "damper material" by leveraging a certain load response. - Features - - High weather resistance due to EPDM (ethylene propylene rubber) - Operating temperature range: -20 to +80°C - Sulfur-free grade with free sulfur measured below the detection limit - Flame retardant/oil-resistant grade (railway flame retardant compliant) * Can be cut to the required length and delivered with adhesive tape - Instantly restores from a compressed state - High shape retention - Extremely low permanent deformation strain - Soft sponge suitable for a wide range of applications

Non-deforming rubber packing for steamers and steam cabinets.

Non-deforming rubber packing for steamers and steam cabinets.

Are you facing issues with the wear of the rubber gasket in your steamer? By replacing it with a non-wearing rubber gasket, you can significantly reduce the frequency of replacements!

Are you experiencing steam leaks due to the deterioration of the rubber packing in your steamer or steaming cabinet? By replacing it with a rubber packing that does not deteriorate, you can significantly reduce the frequency of replacements and effectively address steam leaks caused by packing deterioration, thereby greatly decreasing the frequency of replacements due to deterioration. The rubber sponge material used here is EPDM, which excels in chemical resistance, cold resistance, ozone resistance, and aging resistance. By adding the characteristic of "non-deterioration" to the inherent elasticity of sponge rubber, replacements due to deterioration become unnecessary. Additionally, by developing this concept further, it can also be utilized as a "damper material" by taking advantage of its consistent load response. - Features - - High weather resistance due to EPDM (ethylene propylene rubber) - Operating temperature range: -20 to +80°C - Sulfur-free grade with free sulfur below the measurement limit - Flame retardant/oil resistant grade (railway flame retardant compliant) * Custom cutting to the required length is available, and it can be delivered with adhesive tape - Instantly restores from a compressed state - High shape retention - Extremely low permanent deformation strain - Soft sponge suitable for a wide range of applications
