ASTM A53 Type E pipes



 

 

SCOPE

Covers black and hot-dipped galvanized electric-resistance welded Grade A& B pipes. Is intended for mechanical and pressure applications for ordinary uses in steam, water, gas and air firefighting systems lines.

MANUFACTURING:

Using  the  German  Austrian  made  tube  mill  VOEST  ALPINE  with  state  of  art  THERMATOOL  SOLID ESTATE welding to produce our pipe with the best of hot rolled steel.

QUALITY CONTROL:

ASP has a long history of quality commitment.  ISO  certified  since  1994,  each  production  steps   are monitored by quality assurance routine   to maintain the quality of pipe produced, A  standard  procedure  that  each  length  of  pipe  produced  to  be  hydrostatic  tested  for  a  pressure  of  60  Bar,  this through test gives a high assurance for ASP pipes users.

Flatting and Bending tests are carried on as per requirements of standard.
