Hydrogen Energy Tube/Ultra High Pressure Tube
Stainless steel tubes used in the hydrogen energy industry are specially designed to meet the demanding operating conditions of
hydrogen energy systems. These materials need to possess good corrosion resistance, resistance to hydrogen embrittlement, and high temperature strength.HuZhou Nickel Alloy Special Material produces precision stainless steel bright tubes (BA tubes) and electropolished tubes (EP tubes). These products are widely applied in various fields such as precision instruments and meters, medical equipment, high purity special gas Tubelines in the electronics/semiconductor industry, heat exchangers, automotive Tubelines, laboratory gas lines, aerospace, and dedicated sectors of the hydrogen energy supply chain (low, medium, ultra-high pressure):Stainless steel tubes for nitrogen generation systems, Stainless steel tubes for hydrogen storage,
High-pressure and ultra-high-pressure tubes for hydrogen refueling stations, Stainless steel tubes for food ultra-high-pressure
sterilization,Stainless steel tubes for ultra-high-pressure water jets.
Product advantages: outer wall alkali washing, degreasing and dewatering, inner wall alkali washing, inner wall washing, inner wall
drying, bright annealing, polishing, inner wall cleaning, protective plugs.
