ASTM A335 P22 Alloy Seamless Steel Tube for Power Plant
Model No.: IR-B steel pipe
We are supplying Seamless Alloy Pipe with big diameter and wall thickness. This kind of alloy pipe are widely used at power plant, boiler industry, mechanical making, chemical plant, nuclear power industry, etc.
Standard: ASME SA106, ASME SA335, ASME SA333, DIN17175, EN10216-2, GB5310, GB3087.
Steel grade: SA335 P11/P12/P22/P91/P92, WB36, 10CrMo910, 20G, 15CrMo, 12Cr1MoVG,
SA333 I, SA333VI, ST45.8/III,etc
Outer diameter: 219mm~1066mm
Wall thickness: 15mm~120mm
Tolerance of size of our seamless alloy pipe:
|Type of pipe||Outer diameter||Wall thickness|
|OD (mm)||Tolerance (mm)||WT (mm)||Tolerance (mm)|
|Hot rolled pipe||219~457||±1.0%||≤20||-10%~+12.5%|
Further more, the plant has large-scale cold rolling machine(by 1200t, 1600t, 2000t), the maximum cold rolling diameter can be 920mm. Cold rolling technics can improve the precision of diameter and wall thickness. So we can supply high steel grade steel pipe with big diameter and thin thickness.
