SS Seamless Stainless Steel Tube Coil

SS Seamless Stainless Steel Tube Coil is a seamless tube manufactured from duplex stainless steel 2205 (UNS S32205). Seamless UNS S32205 stainless steel coils offer long, continuous lengths without welds, providing uniform mechanical properties, excellent pressure resistance, and reduced leak risk. It is commonly used in the petrochemical industry.
Outer Diameter: 1.5mm-26mm (customizable)
Wall Thickness: 0.2mm-2.5mm (customizable)
Length: Can be customized upon request
Steel Grade:2205 (UNS S32205)
Standard: ASTM A789 / ASTM A790

Products Description

SS Seamless Stainless Steel Tube Coil

Advantages of SS Seamless Stainless Steel Tube Coil

In Oil and Gas Industry, Our products feature seamless designs, eliminating weak points and reducing the risk of leaks in high-pressure and subsea conditions.
In Chemical and Petrochemical Processing, Our products undergo surface treatment and internal polishing to create smooth internal surfaces, reducing scaling and fouling, improving heat transfer efficiency, and are suitable for heat exchangers.
Marine and Desalination: 2205 duplex stainless steel resists pitting and crevice corrosion in high-chloride environments, extending pipeline life and reducing costs.

Applications of SS Seamless Stainless Steel Tube Coil

Oil and Gas Industry: Hydraulic control lines, chemical injection, subsea umbilicals
Chemical and Petrochemical Processing: Heat exchangers, reactors, process piping
Power Generation: Condenser piping, feedwater heaters, steam coils
Food, Beverage, and Pharmaceutical: Purified water systems, steam coils, sterile piping
Marine and Desalination: Cooling water systems, brine heaters, fresh water generators
