Gasket Packing Q&A No. 2

Gasket Packing Q&A No. 2

I will answer your questions about the causes of leaks that occur during airtightness testing!

Daiko Corporation will answer your questions regarding gaskets. "What could be the cause of a leak during a pressure test using a joint sheet?" → (1) The shape is F.F (full face). (2) Stress relaxation (compression of the gasket) has occurred. (1) F.F. gaskets require a greater tightening force compared to F.R. (ring type) gaskets because they have a larger contact area with the flange. A leak may have occurred due to insufficient tightening surface pressure, so we recommend changing the shape to F.R. (2) There is a possibility that the tightening force has decreased due to stress relaxation (compression of the gasket). Please retighten with the initial tightening force. *For more details, please refer to the PDF document or feel free to contact us.

Gasket Packing Q&A No. 4

Gasket Packing Q&A No. 4

I will answer your questions about what to do if Teflon is hard and won't stop!

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. "What should I use if Teflon is too hard and won't stop?" → We recommend Teflon cushion or soft Teflon. The core joint sheet is soft, making it easy to conform to flanges, which improves sealing performance. Soft Teflon is pure Teflon, so it can be used in processes that are sensitive to impurities. When you actually use it, we will help you select the appropriate gasket, so please feel free to consult us. *For more details, please refer to the PDF materials or feel free to contact us.

Gasket Packing Q&A No. 5

Gasket Packing Q&A No. 5

What is the difference between Teflon cushions with felt and those without felt?

Daiko Co., Ltd. will answer your questions regarding gaskets and packing. Products like T9010-A6 and V7030(S) allow for sealing at low surface pressure by sandwiching a soft felt material in the joint sheet to improve sealing performance. However, when used in areas exposed to rain or condensation, the felt can absorb moisture, making it unsuitable. In such cases, it is better to use joint sheets like T9010-A5 or V7030(N) along with products that only have a Teflon coating.

Gasket Packing Q&A No. 7

Gasket Packing Q&A No. 7

Have regulations been established for ceramic fiber-related products?

Daiko Corporation will answer your questions regarding gaskets and packing. 〇 About RCF (Refractory Ceramic Fiber) Regulations In November 2015, the Specific Chemical Substance Hazard Prevention Regulations were amended and enforced, leading to regulations concerning the handling of RCF. The purpose is to strengthen measures to prevent health hazards for workers related to refractory ceramic fibers. The "Ordinance to Partially Amend the Enforcement Order of the Labor Safety and Health Act" (Ordinance No. 294 of 2015) was promulgated on August 12, 2015, and the "Ministry of Health, Labor and Welfare Ordinance to Partially Amend the Labor Safety and Health Regulations" (Ordinance No. 141 of 2015) was promulgated on September 17, 2015. 〇 Transition to Biodegradable Ceramic Fibers In response to the regulations, we have changed the conventional ceramic fibers to biodegradable ceramic fibers developed to have solubility even when they enter the body. In terms of performance, the only difference is between fibers that dissolve in biological water (RCF-compliant products) and those that do not dissolve (RFC non-compliant products). We guarantee that there are no products that are inferior in performance compared to existing products.

Gasket Packing Q&A No. 9: Gasket Surface Leakage Edition!

Gasket Packing Q&A No. 9: Gasket Surface Leakage Edition!

What causes leaks when using gaskets? - Surface leak edition -

There are various factors that can cause leaks when using gaskets, but this time I will explain about interface leaks. ◆ What is an interface leak? It is a phenomenon where internal fluid leaks through the interface between the sealing material and the opposing surface (such as a flange or shaft). ◆ Countermeasures Fill the minute gaps between the sealing material and the opposing surface with clamping force. ◆ Requirements for sealing materials - Compatibility - Resilience (to respond to pressure drop due to vibrations, thermal loads, etc. during operation, and to prevent the occurrence of minute gaps)
