Seamless Alloy Steel Pipe
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, strength or chemical resistance.
Pipes made of alloy steel have exceptional performance properties. These are generally developed for energy-related applications involving oil and gas drilling and are subjected to stresses in machine parts. Alloy Steel Tubes are also used in daily life, 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.
Backed by a team of professionals and sound production unit, we have been able to provide our clients with an impeccable Alloy Steel Seamless Boiler Pipe. This range includes Alloy Steel Seamless Boiler Tubes.
Developed with advance technology, these products are in compliance with the defined parameters of the industry. These offered alloy pipes are available with us in divergent sizes and specifications meeting divergent demands of the clients.
ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy- Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as [P Grade", chome moly pipe is popular in P-Grades P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.
A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is the most effective single additive that increases high temperature creep strength. It also enhances the corrosion resistance of steel, and inhibits pitting. Chromium (or chrome) is the essential constituent of stainless steel. Any steel with 12% or more Chrome is considered stainless. Chrome is virtually irreplaceable in resisting oxidation at elevated temperatures. Chrome raises the tensile, yield, and hardness at room temperatures. The composition chrome moly alloy steel pipe make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.
