Company Profile Professional production of seamless Shanghai Maxmetal Co.. (Maxmetal) is a professional global steel supplier and China-leading manufacturer of cold drawn and hot-finished seamless steel tube/pipe, the authorized agent of TPCO, Wuxi Zhenda Steel Tube Mfg., Huaian Zhenda, Jiangyin Yueyue Chao Steel Pipe Mfg, and Tianjin Dalipu (Algeria exclusive agent), and most valuable stockist of seamless pipes/welded pipes/stainless steel from Angang Iron & Steel, TPCO, HYST, Changbao Steel Tube, Jianlong Steel Group, Molong Seamless
Also used to produce a variety of conventional weapons, barrels, shells and so on. Concentricity:The process of manufacturing seamless pipe is a hole punched out in a stainless steel billet temperature of 2200 ° f the, in this high temperature, the tool steel by stamping and drawing softens and spirally from Kongzhong Cheng-shaped out. So that the wall thickness of the pipe is not uniform and high eccentricity.

It is also utilized to produce pipeline, container, equipment, pipe fittings, numerous others. Dimension Range of EN10216-1 Seamless Steel Tube. Outside Diameter (O.D.):16 mm to 273 mm
How steel pipe is made - material, manufacture, making
HistoryDesignRaw MaterialsThe Manufacturing ProcessQuality ControlPeople have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists who diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. Clay tubes that were used by other ancient civilizations have been discovered. During the first century A.D. , the first lead pipes were constructed in Europe. In tropical countries, bamboo tubes were used to transport water. Colonial What is a hot rolled seamless steel pipe? - www Hot-rolled seamless steel pipe is a large category of seamless steel pipe, which is divided according to the production method. Hot rolling is relative to cold rolling, cold rolling is carried out rolling at room temperature, and hot rolling is carried out rolling at the recrystallization temperature. Seamless steel pipe is named relative to the welded steel pipe, seamless steel pipe is usually made of round steel perforation and reprocessing, welded steel pipe
Hot-rolled seamless steel pipes and cold-rolled seamless steel pipes are formed by the process of steel or steel plate, they have a great impact on the microstructure and properties of steel, the rolling mill is mainly hot-rolled, cold-rolled only for the production of small steel and sheet. Description:Standard ASTM A106, ASTM A53, API 5L Gr.B, DIN17175, etc Material ASTM A106B, ASTM A53B
Production process and production technology of hot rolled Cold rolled (drawn) seamless steel pipe includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, alloy thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel pipe, stainless steel pipe and special-shaped steel pipe. Generally, the outer diameter of hot-rolled seamless pipe is greater than 32mm, and the wall thickness is 2.5-75mm.
Seamless Pipe - Seamless Tube, Seamless Pipe SupplierSeamless pipe is widely used in many industries, for its applications are irreplaceable. Generally speaking, the seamless tube is mainly made of steel. According to different production methods, it can also be divided into several varieties:hot rolling steel pipe, cold rolling steel pipe, cold drawing steel pipe and extrusion steel pipe.
Depending on the application, there are thick walled tubes and thin walled tubes. Seamless steel pipes are mainly used in petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, casing pipes, automobiles, tractors, and high-precision structural steel pipes for aviation. Classification:Seamless steel pipes along the perimeter of their cross section. According to different production methods, it is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe
