Our professional management of a variety of cold drawn (rolled) seamless 20cr tube, cold drawn (rolled) pipe, 20 # cold drawn (rolled) seamless steel pipe, 45 cold drawn (rolled) seamless pipes, cold-rolled precision steel, non-standard seamless pipe, finishing seamless steel tubes, seamless steel models complete. It applies to all areas of construction, mining, textile, electric power, boilers, machinery, military and other. Companies with good reputation and quality products, a strong, low price reputation more than 30 provinces, municipalities, autonomous regions, municipalities and abroad, the product won user dependent. To meet customer demand, in December 2006 the company has invested more than 15 million to introduce the most advanced, the largest rolling finishing mill specification 6, 45 meters thermal annealing furnace (Liaocheng largest, to stress annealing is not deformed, can not afford to scale), precision-point calibration machine 1 (Liaocheng's first) produce specifications diameter 6mm - 219mm, wall thickness of 0.5mm-32mm, various materials precision bright seamless steel tubes, welded pipe, smooth appearance, thickness uniform, high precision, can be made hydraulic cylinders, cylinder, auto parts, motorcycle parts, electric car parts, agricultural vehicles and parts Shanghai 20cr tube, petrochemical structures, power structures, marine structures, aerospace structures pieces, bearing coats, pneumatic components, the low-pressure boiler tubes, etc., can be customized according to customer requirements. Now I have a lot alloy pipe, pressure pipe, seamless square tube, shaped seamless steel pipe spot, will be preferential prices, wholesale and retail ways, to provide you with fast quality service, welcome new and old customers to negotiate, Power Conference. Specializing in the production of high-precision cold-rolled seamless steel tubes of various thin-walled steel Jiangsu 20cr tube, thick-walled seamless shiny smooth surface, uniform thickness, high precision according to customer requirements to ensure that the error in 0.1mm - 0.05mm, small caliber thin-walled tube 0.05mm - within 0.03mm, cold-rolled precision round steel, all kinds of material size diameter cold drawn seamless tube where 20cr ensure market price. Our products are widely used in machinery, petroleum, chemical industry, especially hydraulic, motorcycle, automobile industry other steel tube precision, finish, there are areas of high mechanical performance requirements. .
