Outer Braided Stainless Steel Wire Reinforced Graphite Yarn
High-purity graphite yarn with an outer braided stainless steel wire (304/316) jacket. Excellent mechanical strength, temperature resistance up to 650°C and corrosion resistance (pH 1–14) for high-pressure pipe and valve sealing.
Inquire about Outer Braided Stainless Steel Wire Reinforced Graphite YarnOuter braided stainless steel wire reinforced graphite yarn uses high-purity graphite as the base material, with an outer layer of braided stainless steel wire (304/316) forming a metal jacket. The core is precisely compacted during forming, giving the yarn excellent elasticity and abrasion resistance.
The product has a compact structure. The metal braid provides outstanding mechanical strength and resistance to compression deformation, while the graphite core ensures stable sealing performance in high-temperature, high-pressure and corrosive media. It is widely used for pipe and valve sealing in petrochemical, natural gas, chemical and marine industries.
Key features include: high temperature resistance (up to 650°C), corrosion resistance (suitable for pH 1–14), low friction coefficient, long service life, constant sealing force under high pressure, and a variety of sizes available on request.
Applications / Fields of Use: suitable for petroleum refining, chemical synthesis, natural gas transmission, seawater desalination and low-temperature liquid transfer, especially in high-pressure, high-temperature, abrasive media and applications requiring frequent disassembly.
