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%
>20~40 -10%~+10%
457~1066 ±0.9% >40~70 -7%~+9%
>70~120 -6%~+8%
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.
