400℃ Heat Resistant and Flexible Standard 'Glass Fabric Gasket' Explanation

400℃ Heat Resistant and Flexible Standard 'Glass Fabric Gasket' Explanation

A thorough explanation of why the standard woven fabric gasket No. 1374 continues to be a staple choice at many sites!

"I want to reduce costs for the boiler manhole packing." "I need a flexible gasket that fits the flange of the exhaust duct." "Is there an easy-to-use sealing material for a hot air line at around 400°C?" The selection of sealing materials for high-temperature equipment always requires a balance between performance and cost. In particular, in areas such as the inspection openings (manholes, handholes) of boilers and the connection points of exhaust and hot air ducts, where high clamping force cannot be applied and complete airtightness is not required, an over-specified high-performance gasket may not necessarily be the optimal solution. *For more details on the column, please refer to the related links.

Mechanisms of "Thermal Degradation" and "Crazing"【Technical Explanation】

Mechanisms of "Thermal Degradation" and "Crazing"【Technical Explanation】

An explanation of the risks of "over-tightening" that should never be done, based on technical materials from Nichias!

In the field of plant maintenance, issues with steam line leaks are never-ending. Many of these problems stem from a "selection mistake" where "joint sheets for general piping (water and oil)" were carelessly used in steam piping. "I thought it would be fine because the catalog said it was heat-resistant up to 150°C." This complacency can be fatal. There are clear physical reasons why only "steam-specific" materials should be used for steam piping. This article will explain the mechanism of "thermal degradation (hardening)" that occurs when the wrong gasket is used, as well as the risks of "re-tightening," which should absolutely be avoided, based on technical materials from Nichias. *For detailed content of the column, please refer to the related links.

Processing examples of partially cut gasket lower parts.

Processing examples of partially cut gasket lower parts.

Special shape support through water jet processing.

■Overview of Processing Example This case involves the processing of a gasket with a lower cut using the V6500 joint sheet. The outer circumference is primarily circular in shape, but it features a linear cut at the lower part of the gasket, which was specified to avoid interference with the equipment structure and surrounding components. The bolt holes are evenly spaced, requiring a balance between hole position accuracy and outer shape precision. In this case, water jet processing was adopted without using a die. By continuously processing the arc section and the lower cut section, we achieved the reproduction of the shape as per the design data and improved positioning accuracy during assembly.
