Xuanhua District seamless steel pipe plant | large diameter seamless steel pipe plant | thick-walled seamless steel pipe Cangzhou City Dongtai Steel Pipe Co., Ltd. Sales Manager at Zhiqiang: 13393378282 15932715956 0317-6289066 North China specializing in the production and one of the large enterprise sales of steel pipe and pipe fittings, Yanshan County, Hebei Province Industrial Park is located in the pipeline equipment production base. East of Huanghua Port, north of Beijing, Tianjin, State Road 205, State Road 104, Beijing-Shanghai Railway cross transit, domestic transportation is very convenient; addition is only 200 kilometers away from Tianjin Xingang, to provide a more convenient conditions for the export business. The company covers an area of ??130 acres, 270 million yuan in fixed assets, the company has advanced production equipment and complete detection means. Now has eddy current flaw detector, ultrasonic flaw detector, nondestructive testing equipment, as well as hydrostatic testing machine WE-600 universal testing machine, WE-1000A hydraulic universal testing machine, as well as a full set of metallographic test equipment and physical chemistry instruments. The company has strong technical expertise, service capabilities and market competitiveness. The right to import and export company in 2008, based on the domestic market and exported to Europe, America and Southeast Asia, Africa and other places, and to establish long-term strategic partnership of cooperation with internationally renowned enterprises, praised by customers. The product is made of high quality steel coil after passing reinspection the slitting or with volume automatically forming and welding, computer control of the best fusion temperature, remove the inside and outside of the steel pipe burr, non-destructive testing of qualified steel pipe in minimal oxidation the whole atmosphere heated to 910 ℃ -950 ℃ degree released, in addition to the multi-pass rolling scales through the stretch reducing mill, the steel pipe throughout the microstructure, grain state, geometry and mechanical properties fully homogeneous. Products perform API SPEC 5L, API SPEC 5CT, EN10217 standard. The products are widely used in flammable and non-flammable fluid pipes and boilers, steel structure. Seamless steel pipe, also known as hot-rolled seamless steel or hot-rolled steel. Seamless steel pipe seamless Production Pipe important to reducing tension tension-reducing process is a continuous rolling process of the hollow base material without mandrel. Pipe welding quality conditions to ensure that the mother, welded pipe tension reducing process welded pipe as a whole is heated to 950 degrees Celsius, and then by reducing tension (tension reducing machine a total of 24 times) rolled into outside finished tube diameter and wall thickness, the use of this process is the production of hot-rolled steel pipe substantial difference to the ordinary high frequency welded pipe, the microstructure and mechanical properties of the welds and parent through the heat of the furnace to reach full consensus addition makes steel pipe dimensional accuracy, especially the roundness of the pipe body and the wall thickness of accuracy) is superior to similar seamless pipe reducer rolling initiative dominated by multi-channel tension. Realms of the world's developed production fluid tubes, boiler tubes, a large number of taken welded pipe seamless process, with the development of society, the domestic hot-rolled welded pipe seamless pipe the situation is gradually replacing the already formed. Market philosophy, the company adhere to the "integrity of management, quality marketing, and strive to win-win" correct operating
