Steel Pipe Traders

Steel Pipe Traders may be required by the petrochemical, water, pipeline, and mechanical industries throughout the world, At use in a huge range of industries and applications. Steel pipes appear in thousands of types and sizes, and yet there are some standards that any steel pipe Traders must meet. This is going to depend upon the application to which that pipe is put, and some of the most common applications and standards appear below.

Description

However, sizes on all standards vary, with pipe size specified by two designations – NPS (nominal pipe size) for sizes using inches, and a separate schedule for wall thicknesses. Buyers must know their design specifications in order to select the right range of pipes or tubes, fittings, flanges, joints, and couplers. You can also shop for reinforcing bar product. We are also Deformed REBAR Traders, supply and export rebar debar and deformed steel products on average cost.

In American standards (NPT) and the European designation (ISO) are equivalent to the NPS sizes, though noted as DN or diameter nominal and indicated in millimeters rather than inches.

NOTE: NPS may also be described as NB for nominal bore.

Pipe grades include the following schedule:

• 5s • 60
• 5 • 80s & EH
• 10s • 80
• 10 • 100
• 20 • 120
• 30 • 140
• 40s & STD • 160
• 40 • Dbl. EH (XXH)

EH= Extra Heavy STD=Standard Dbl.=Double

There are also numerous grades ranging from A and B grades to API specified grades such as E-75, S-135, 5D and 7. There are also specialty sizes such as C955, C1053 and high strengths like S140 and S150. Sizes on pipes, casing, fittings, couplers, and tubes vary, but typically will be available from 1/8″ to 72″

Standards will adhere to specific guidelines provided by the following:

Any user of steel pipe exporter must understand the codes to be followed when designing any sort of piping system or structure. The steel pipes will then need to be an appropriate grade and tensile strength to live up to the anticipated use.

We are the major supplier of steel pipe Traders, fittings, flanges, joints, galvanized threaded and coupled carbon steel line pipe to the water, petrochemical, pipeline and mechanical industries around the world.
