Duplex Stainless Steel Lined Pipe - China

Liner: 2205(S31803), 2506 (S31804, S32740), 2507···Etc;

Backing: API 5L, API 5CT, ASTM, ASME···Etc We can produce and deliver nearly any duplex material requirement in lined pipe.

While Duplex 2205 is the most common duplex lined material product we supply, we can also deliver Duplex 2304 and Duplex 2207 with reduced lead times as these alloys are stocked.

Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel lined pipe with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or317L austenitic stainless steel tube in almost all corrosive media.

It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

Technical details at a glance:

• Size range from OD 15 mm (0.6") up to142, 0 mm (56")

• Random lengths up to 12 m (up to 12 m without circumferential weld)

• Production acc.

to API or ISO Advantages of mechanically lined pipes:

• Cost savings of up to 40 % compared to solid pipes

• High corrosion resistance at the inside and high pressure resistance at the outside

Common alloy grades:

• S31803(2205), S32750(2507)
