BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, Q355NH equivalent astm material plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.
ASTM A213 T9 seamless pipe is ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. BBN steel company supplies Cr-Mo low alloy steel grades of T2, T5, T5b, T5c, T9, T11, T12, T17, T21, T22, T23, T24, T36, T91, T92, T122, and T911. The tubing sizes and thickness usually furnished to this specification are 1/8″(3.2 mm) in inside diameter to 5″(127 mm) in outside diameter and 0.015″ to 0.500″(0.4-12.7 mm) in minimum or average wall thickness.
Q355NH equivalent astm material, low alloy high strength steel has good atmospheric corrosion resistance and is widely used in engineering structure construction. Most of the engineering structures are used in the atmosphere or marine environment. A small amount of Cu, Ni, Cr, P and other elements are added to the low alloy high strength steel, which effectively improves the corrosion resistance of the engineering structure in the atmosphere, sea water and soil. If 0.2% - 0.5% copper, 0.05% - 0.1% phosphorus and aluminum are added, the corrosion resistance of steel can be improved obviously, and the effect of adding copper and phosphorus at the same time is the best.
"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, Q355NH equivalent astm material tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
