Bellowman is a merchant exporter of alloy steel pipes and alloy steel tubes used for many different purposes such as the power generation, refining and petrochemical industries. We are specialized in offering our customers series of precision engineered alloy steels, various standard and grades are available.

 

Alloy steel contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous. Addition of such alloying elements is usually for the purpose to increase hardness, tensile strengths, corrosion resistance and the ability to withstand high temperatures.

 

Pipes made of alloy steel have exceptional performance properties, catering to the domestic, professional or industrial needs. In recent years, the demand for alloy steel tubing has been increasing along with the economic growth.
