Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of composite gaskets, it is recommended to prioritize confirming technical parameters such as pressure rating, temperature range, and material combination to ensure compatibility with equipment sealing requirements.
  • In high-voltage scenarios such as chemical or electrical engineering, the corrosion resistance and elastic recovery rate of composite gaskets are key indicators, and corresponding product specifications need to be selected based on the characteristics of the medium.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to balance procurement risks and long-term cooperation stability.
  • Composite gaskets are commonly used in pipeline flanges or reactor seals, and selection should be based on detailed parameters such as interface size and surface roughness during procurement.

Knowledge Base

Q

Flexible graphite composite gasket, also known as reinforced graphite composite gasket or high-strength graphite gasket, is made of graphite composite plate by punching or cutting. Compared with pure graphite gasket and general metal gasket, it has better compression resilience, high and low temperature resistance, and corrosion resistance. Graphite composite board is composed of a sprint metal toothed plate, a metal mesh plate, and a flexible graphite material pressure roller, which are composite compared to ordinary ones
