Product Introduction

The Nuclear Grade Graphite Gasket is a high-performance gasket made from nuclear-grade materials, designed for use in flanges of pipes and equipment. It ensures constant sealing stress under metal-to-metal contact conditions. The gasket meets requirements for extremely low leakage, resistance to thermal shock, and radiation, making it widely used in harsh operating conditions such as high temperatures, high pressures, large temperature and pressure fluctuations, corrosive media, and radiation environments.

Product Features

After installation, the gasket maintains contact with the flange outer ring and applies sufficient additional load. The BMCSG gasket addresses the loss of sealing stress caused by external factors (such as temperature and pressure fluctuations, thermal shock, and bolt stress relaxation and creep), ensuring the safety and reliability of the seal.

Application Scenarios

Suitable for sealing flanges of equipment and pipelines in industrial sectors such as nuclear power, chemical, refining, petrochemical, metallurgy, shipping, and energy.
