Our highly-skilled manpower is dedicated to producing the finest quality steel pipe, pipe fittings, meeting a wide variety of material specifications. Their knowledge and experience of metal properties, welding procedures and quality control have set the pace and standard expected by our customers world-wide.
Commonly fabricated materials and specifications are:

Alloy steel is often subdivided into two groups: high alloy steels and low alloy steels. The difference between the two is defined somewhat arbitrarily. However, most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon, is high alloy steel.

Available standard and specification as below:

ASTM A213 : Seamless Ferritic and Austentic Alloy Steel Boiler, Superheater and Heat-Exchanger Tubes
ASTM A333:  Wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures
ASTM A335: Seamless Ferritic Alloy Steel Pipe for High-Temperature Service
ASTM A519: Seamless Carbon and Alloy Steel for Mechanical Tubing

Stainless Steel

Types of stainless Stock room Types of stainless

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry.

Black steel

Black steel is a term given to steel pipe with a black oxide scale on the surface. This black oxide scale is formed when the pipe is forged and is typically sealed with a protective oil to prevent corrosion. Because of this oxide scale and protective film, black steel pipe requires little maintenance and is used for a wide variety of applications, including in water, steam, air and gas services. Black steel pipes are typically cut and threaded in the field.
