Fluid Conveying Pipes

Are usually many standards applicable for fluid seamless steel pipes, such as ASTM A106, ASTM A179, ASTM A192, ASTM A333, ASTM A335, JIS G3452, BS 3059, DIN 1629, DIN 17175 and API 5L. We mainly produce various grades of fluid steel pipes, such as 10#, 20#, Q295, Q345, Q390, Q420, Q460, etc.

Description Fluid conveying pipe is a sort of fluid seamless steel pipe. With hollow section absolutely no welding seam, it really is often used for conveying fluid, pertaining to instance petroleum, natural gas, water and some solid materials. Fluid steel pipe is of light weight and is widely utilized for producing structural components and mechanical parts, such as petroleum drill rod, automobile transmission shaft, bicycle frame and steel scaffold used for construction.

We use fluid seamless steel pipes to produce annular parts, which improves the material utilization rate, simplifies the manufacturing procedures, and saves material and processing energy. Fluid steel pipe furthermore be used to imply coal gas, oil, air, warm steam and other pressure fluid.
Manufacturing TechnologyWe adopt heat treatment (annealing and normalizing) to process fluid seamless steel pipes.

Dimension Deviation of Fluid Steel Pipe

Type Size (mm) Allowable Deviation of Fluid Pipe
General Class High Class
Hot-Rolled Pipe OD Total ± 1% ( Min. ± 0.50 mm )
WS Total +15% -12.5% (Min. +0.45/-0.40 mm )
Cold-Drawn Pipe OD 6 to 10 ± 0.20 mm ± 0.15 mm
> 10-30 ± 0.40 mm ± 0.20 mm
> 30-50 ± 0.45 mm ± 0.30 mm
> 50 ± 1% ± 0.8%
WS ≤ 1 ± 0.15 mm ± 0.12 mm
> 1-3 + 15% - 10% +12.5% -10%
> 3 + 12.5% -10% ± 10%

1. OD refers to the outer diameter or outside diameter. WS refers to the wall thickness.
2. We also supply fluid seamless steel pipes according to the deviation in ASTM standard.
