2507 Duplex Ss 3/8 Inch Capillary Coiled Tubing

2507 Duplex Stainless Steel Capillary Tube 3 / 8 Coiled tubing ASTM A789

The 2507 duplex stainless steel combines the most beneficial properties of many ferritic and austenitic steels. Due to the high content of chromium and molybdenum, this steel has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. The duplex microstructure ensures that the steel has a high resistance to stress corrosion cracking, and a high mechanical strength.

The 2507 duplex stainless steel capillary tube is mainly used in the oil and gas industry; offshore rock-breaking oil platforms (heat exchanger tubes, water treatment and water supply systems, fire fighting systems, water spray systems, water stabilization systems); petrochemical equipment; desalination equipment (and high-pressure pipe and seawater pipe in the equipment); mechanical and structural parts that require both high strength and high corrosion resistance as well as (waste) gas purification equipment.
