Boiler tubes

 Seamless carbon molybdenum alloy steel boiler and superheater tubes. ASTM A209 Grade T1a Alloy Steel Seamless Tubes are Carbon Steel Tubes with subsequent addition of chromium, molybdenum and sometimes vanadium are known as chrome Moly Tubes. ASTM Specification alloy steel Tubes are used for high temperature service applications. Seamless Alloy Steel Tubes according to ASTM A209 Grade T1a are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition. ASTM A209 Grade T1a Alloy Steel Seamless Tubes have a typical chemistry with additions of 0.44-0.65 Molybdenum. Bearing minimum tensile strength of 365 Mpa ASTM A209 Grade T1a Tubes have a minimum yield strength of 195 Mpa. ASTM A209 ASTM A209 cover several grades of minimum wall thickness seamless carbon molybdenum alloy steel, boiler and superheater tubes. This specification covers tubes 1/2 to 5 in. [12.7 to 127 mm] inclusive, in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm],

 ASTM A335 P9 Alloy steel pipe apply to petroleum, chemical industry, electric power, boiler, high temperature resistant, low temperature resistant, corrosion resistant. ASTM A335 P9 is the part of ASTM A335, The pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding. The steel material shall conform to chemical composition, tensile property, and hardness requirements. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices. The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
