20# Thick Wall Precision SeamlessTube is a kind of steel pipe with small size tolerance. After cold drawn or hot rolling process ,the high precision steel tube is without oxidation layer in the surface. Precision steel tube can be under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks etc, it is mainly used to produce ASTM A106 GR. B/API 5L GR. B Carbon Steel Seamless Pipe 2.High precision steel pipe diameter surface finish, the customer without processing can be used Directly and ordinary seamless steel tube to the customer and lather, polishing processing. ASTM A106 GR.B/ASME SA106 GR.B/API 5L GR.B Carbon Steel Seamless pipe Features 1.The smaller outer diameter 2.High precision to do small batch production 3
2.High precision steel pipe diameter surface finish, the customer without processing can be used. Directly and ordinary seamless steel tube to the customer and lather, polishing processing. Features:1.The smaller outer diameter. 2.High precision to do small batch production. 3.Cold drawn finished products of high precision, good surface quality. 4.The steel pipe transverse area is more complex. Precision seamless steel pipe extrusion production processDec 27, 2017 · 1, precision hot-rolled seamless steel pipe in the best stress state, reducing the internal defects. 2, easy to achieve cross-section morphology diversity, adapt to varieties, small batch production. 3, in every direction of the performance uniformity. The main method of production extrusion process:electric furnace + electric furnace> forging Seamless Tubes:stainless steel, nickel, titaniumThis is the second level of cold working tubes to reduce their size. Here the tube is pulled through a die which is smaller than the tube, so the end of each tube needs to be machined in order to fit. It will be swaged or tagged before drawing. Following this procedure, the tube end can pass through the die and is clamped to a drawing trolley, also called a pulley, which draws the tube through the die.
Seamless steel pipe for the use of engineering and construction is very widely, it is a hollow steel strip no seams, it is mainly used to transport liquids pipelines, different look and general steel,one of those heavy type steel, it has a strong resistance to corrosion, resistant to general corrosion.. high precision can do small batch production. Seamless-Carbon-Steel-Pipe_Seamless Steel Pipe_Product Product Overview. ASTM A106 seamless carbon steel pipe for high-temperature service. ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels. The Difference between Stainless Steel Precision Tube and This kind of stainless steel precision tubes can save costs and greatly save mechanical processing man-hours, increase production and material utilization, and at the same time help improve product quality and reduce costs. Features of stainless steel precision tube:1) The outer diameter is smaller; 2) High precision and small batch production;

Standard DIN 2391 defines the technical delivery conditions for seamless precision steel tubes according to DIN 2391 Part 1 which are made from the steel grades listed in section 5. Tubes according to this Standard are mainly used where accuracy to dimension and, possibly, small wall thicknesses and good surface condition are required.
