ASTM A53 Pipes

 

Scope:

 

The ASTM A53 Pipes covers black and hot-dipped galvanized ERW Grade A and B pipes. It is intended for mechanical and pressure applications for regular use in steam, water, gas and air firefighting systems lines.

 

Manufacturing:
This pipe is produced using the German-Austrian made tube mill Voest Alpine, which undergoes the state of the art Thermatool Solid Estate welding, using top of the line HRC raw material. 

Quality Control: 
Our commitment to quality dates back to our creation. We have been ISO certified since 1994 and every single phase of our operations are monitored by a rigorous quality assurance routine to ensure that the pipes produced are of top quality. One of our standard procedures includes a hydrostatic test to ensure welding strength.

Chemical and machinal requirements: 
The standard ASTM A53 requirements for grade A and B are maintained.
