GANYEAH Steel is supplying stainless steel welded pipes as per ASTM A312 in common grades such as 304/304L and 316/316L in standard pipe sizes

We can help supply all of the ASTM A312 Stainless Steel Pipes, A312 Seamless/Welded Pipes for use in the oil or natural gas industries.

Stainless steel plate is often referred to as corrosion-resistant steel -it does not stain, corrode or rust as easily as normal carbon steel

SUS304:C≤0.08 Si≤1.00 Mn≤2.00 P≤0.045 S≤0.03 Ni8.00-11.00 Cr18-20
SUS316L:C≤0.03 Si≤1.00 Mn≤2.00 P≤0.045 S≤0.03 Ni12.00-16.00 Cr18-20 Mo2-3

EN 10296-2 Non-destructive testing of the weld is not mandatory. This gives a possible design utilization of 70%, and a weld factor z = 0.7.

Type 304 and 304L grade of pipe exhibit good machinability and have excellent weld-ability characteristic with or without the addition of filler metal

Hardness:Resistance to deformation or indentation. Materials with little resistance are called soft; and those with high resistance are called hard.

Our tubing is made from cold rolled stainless steel strip whose chemical elements are specially controlled to enhance weldability.

To achieve the desired interior surface finish, an abrasive material, fitted onto a pneumatic polishing head, rotates within the tube for many cycles.

Available mechanically polished to 20 μ-in Ra (0.5 μm) maximum ID and 30 μ-in Ra (0.8 μm) maximum OD surface roughness, exceeding ASTM A270-S2

Welded and drawn is the preferred tubing choice in terms of economy, lead time and tolerancing compared to seamless in most instances.

Welded stainless steel pipe is manufactured from 2B or HRAP stainless steel strip - formed (to shape) and longitudinally welded to completed pipe.

When requested we can arrange for shipment and delivery to your dock, or ship your tubes to a third party and if needed can arrange for expedited ship

Mechanical properties:Optimal mechanical and fabrication properties are realised after solution annealing in the temperature range 1075 - 1125°C
