This article explores the common causes of expanded PTFE gasket failure, such as installation damage, creep, temperature and chemical exposure, and improper bolt load, and provides practical prevention strategies to improve sealing reliability and extend service life.

Corrugated gaskets provide better recovery, improved sealing performance under temperature fluctuations, and are often more cost-effective than jacketed gaskets, making them a reliable choice for many industrial sealing applications.

Stamping jacket gaskets are widely favored in heat exchanger applications due to their excellent sealing reliability, dimensional precision, and ability to withstand high temperatures and pressures. This article examines the key reasons behind their preference, including material performance, structural benefits, and long-term durability under demanding thermal cycling conditions.

Double jacket gaskets offer reliable sealing performance in high-temperature and high-pressure applications, thanks to their durable metal outer shell and flexible filler core. They provide excellent resistance to corrosion, thermal cycling, and mechanical stress, making them a cost-effective choice for flanged joints in industries such as oil and gas, chemical processing, and power generation.

This article explores the key reasons for choosing a lens ring joint gasket instead of a spiral wound gasket in demanding flange sealing applications. It highlights the lens ring design’s ability to provide reliable metal-to-metal sealing under high pressure and high temperature conditions, where spiral wound gaskets may face limitations such as blowout risk, lower load capacity, or reduced performance in critical services. The discussion helps engineers understand the performance differences and select the right gasket for severe industrial environments.

Learn the correct procedures for installing special material spiral wound gaskets, covering flange preparation, careful handling, precise centering, and uniform bolt tightening to achieve a secure, leak-free seal.
