Joint sheet related (non-asbestos packing)

Joint sheet related (non-asbestos packing)

We manufacture using die and punch cutting, cutting plotters, and in some cases, manual processing.

A "joint sheet" refers to a gasket sheet made by combining various inorganic fibers, inorganic fillers, and rubber. In the past, asbestos gaskets made primarily from asbestos were used, but after the ban on asbestos use, non-asbestos joint sheets, which are relatively more expensive and have inferior performance, are used instead. Non-as is a trademark of Nippon Valqua. They are manufactured using processes such as die cutting with wooden molds (bikugata), punch cutting, cutting with a cutting plotter, and in some cases, manual processing using cutters and chisels. 【Product Lineup (Excerpt)】 ■ Nippon Valqua Industrial Non-Asbestos Joint Sheet V6500 - Die-cut product ■ V6500 - Processed product, ThreeBond, ThreeSheet 201S die-cut product ■ Nichias Joint Sheet T1120 die-cut product ■ ThreeSheet Packing 210S die-cut ■ Nichias T1995 19X10.5X1.5 *For more details, please refer to the related link page or feel free to contact us.

Non-asbestos joint sheet

Non-asbestos joint sheet

It is a non-asbestos joint sheet based on synthetic fibers.

We will manufacture gaskets using non-asbestos joint sheets for high temperature and high pressure applications, which are the highest peak in the world. 【Features】 ■ Multi-layer (sandwich) structure A three-layer structure with conventional elastomer (NBR) sandwiched between special elastomer (HNBR). ■ Achieves high flexibility at high temperatures The layer using special elastomer (HNBR) as a binder maintains flexibility for a longer period at high temperatures compared to conventional non-asbestos joint sheets, responding to dynamic load fluctuations from the flange area and suppressing the formation of microscopic cracks that can cause leaks. ■ Suppresses thermal decomposition and aging processes The three-layer structure of conventional elastomer (NBR) and special elastomer (HNBR) can suppress rubber hardening due to usage conditions, decomposition due to heat and oxidation, and deterioration of the remachining chain. ■ Lower creep ■ High maximum allowable surface pressure *For more details, please contact us for documentation requests.

Gasket Packing Q&A No. 13: What is compression failure of a seat?

Gasket Packing Q&A No. 13: What is compression failure of a seat?

What is the compressive failure of a joint sheet?

There are several issues with joint sheets, but I will explain the most common case, which is compression failure. ◆Details of the problem 　〇Cracks occurred around the gasket, making it extremely thin. ◆Possible causes 　〇Compression failure due to excessive tightening. 　〇Excessive load applied to a part of the gasket due to lack of parallelism of the flange or deformation. 　〇Localized slippage of the joint sheet due to uneven application of paste. ◆Countermeasures 　〇Tighten without exceeding the allowable tightening surface pressure of the gasket. 　〇Problems caused by improper construction such as single-sided tightening, insufficient tightening, or excessive tightening. 　〇Correct the parallelism and deformation of the flange. 　〇When applying paste, apply it thinly and evenly.
