Marine engineering

ASTM A589 covers four specific types of plain end or threaded and coupled carbon steel pipes designed for water well use.

A691 1-1/4CR alloy steel EFW pipe is commonly used in high temperature, high pressure and corrosive environments.

GNEE steel is one of professional ASTM A213 seamless alloy steel tubes manufacturers and exporters,we can supply different materials for ASTM A213 Bolier tubes with high-temperature

These ASME SA 53 Carbon Steel Grade A Pipes are quality tested on defined parameters, to ensure these are in compliance with the defined quality standards.
