Polished Seamless Stainless Steel Pipe For Liquid Pipeline 0Cr18Ni9 1Cr18Ni9Ti

 

 

 

Stainless Steel Seamless Pipes For Fluid Transport, made according to Chinese national standard GB/T 14976-94.

 

GB/T 14976-94 is a standard applicable for stainless steel seamless pipes which is produced by hot -rolled (extruded and expanded) or cold-drawn (cold-rolled) and used for fluid transport.

 

Steel pipes fall into two categories, i.e. the hot -rolled (extruded and expanded) steel pipes and cold-drawn (cold-rolled) steel pipes.

Manufacture process:

  •   Metallurgical process of steel

Steel shall be smelted using arc furnace.

It is possible to use the other processed for smelting the steel after an agreement is reached between the supplier and the client.

  •   Manufacture processes for steel pipes

Steel pipes shall be manufactured using hot-rolling (extruding and expanding) or cold-drawing (cold-rolling) processes. In case, a special manufacture process is requested by the client, it shall be specified in the contract.

 

Delivery condition:

Steel pipes shall be delivered after the heat treatment and pickling are made in the manufacturer.

 

Mechanical properties:

The longitudinal mechanical properties of steel pipes under heat treatment conditions (tensile strength and elongation) shall comply with the specifications made in the following table. It is possible to determine the yield strength of steel pipes upon the request made by the client when it is specified in the contract.
