Alloy steel pipes are just plain tubing to which a standard composition for steels has been changed by adding specific alloying elements, such as chromium, molybdenum, nickel, and manganese, to achieve superior properties over standard carbon steel. Tailored compositions provide alloy steel pipe with high strength, toughness, and better resistance to both corrosion and temperature extremes. The manufacturers can precisely adjust the type and amount of these elements to create different grades of alloy steel, each having the specific characteristics for industrial needs.
Both types, seamless and welded, are obtainable in alloy steel pipes, which are mainly recognized for their properties of safety and durability under harsh situations. Specially, seamless tubes obtained by solid billet extrusion are normally utilized for those cases with the highest pressure in which no leakage is allowed. On the other hand, the production of welded pipes depends on rolling and welding steel sheets; they are a more economical option for systems with medium pressures.
Freedom from the strictest conditions, the extraordinary properties of alloy steel have made these pipes a nondescript commodity in heavy industries. For instance, their use is extended in power plants for boiler and superheater tubes and in petrochemical industries where transferring of corrosive chemicals and high-temperature fluids is carried out. In the oil and gas industry as well, they are very much convenient for pipelines, drilling operations, and refinery equipment where high pressure and the presence of corrosive agents are expected. Moreover, their high strength to low weight ratio makes them suitable for aerospace and automotive parts as well. Although carbon steel is cheaper at the beginning of the process, the long-term cost-efficiency of alloy steel pipe is mainly due to their almost non-existent maintenance requirements and long service life.
