The steel is then cleaned using tanks of sulfuric acid followed by cold and hot water and transported to pipe-making factories. Developing Welded and Seamless Pipes For welded pipes, an unwinding machine unwinds skelp and passes it through rollers to cause the edges to curl and create pipe shapes.
Learn MoreCold Drawn Seamless Mechanical Steel tube and pipe is produced by drawing tube through a die or cold rolling it to give it a more uniform diameter. For this reason Cold Drawn Seamless Mechanical Steel tube is stronger than other types of steel tube. Cold Drawn Seamless Steel tube and pipe can be used as a finished product or can be machined.
Learn MoreManufacturing process We manufacture the cold drawn steel pipe by the following process. Steel billet → heating → punching → head making → annealing → pickling → copper plating → cold drawing → semi-finished pipes → heat treatment → straightening → Hydraulic test →UT → labeling → warehouse entry.
Learn MoreSeamless tube stainless steel material standards include ASTM A213, ASTM A312, ASTM A269, A270 and etc. The most common grades in Grade 304 and Grade 316. Manufacturing processes of seamless pipe. There are mainly 3 methods adopted by seamless steel tube suppliers to make seamless tubes: Hot Rolled, Cold Rolled (Coiled), Thermal Expansion.
Learn MoreDetailed introduction of Precision Seamless Cold Drawn Steel Pipe:. This series products are made with high quality raw material. Advanced manufacture equipment’s and the exquisite craft, technology, characteristic of high precise size, good quality surface, stable performance, especially for the reliable durable performance under high temperature.
Learn MoreCold rolling refers to the process of cold drawing, cold bending, cold drawing and other cold processing at room temperature to process the steel strip into various types of steel. Cold-rolled seamless pipe (GB3639-2000) is a cold-drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish for
Learn MoreIf a seamless carbon steel pipe is used, then it is driven into the ground by a large machine and may be filled with concrete after it is pile-driven to protect the pipe and make it even sturdier. This type of pipe generally is very durable and does not bend easily from stress, so it is uniquely suited for deep foundations.
Learn MoreA cold drawn seamless pipe has better dimensional tolerance, a higher surface finish and better mechanical properties than an equivalent hot finish seamless pipe. For applications that can make
Learn Moreseamless pipe is also called cds pipes (cold drawn seamless pipes). it is used widely in machining parts, shafts, bearings, cylinders having strength of 75000 psi tensile..
Learn MoreWe are one of the prominent suppliers, importers, and stockists of a wide range of Carbon Steel Seamless and ERW Pipes & Tubes.Further, we are also engaged in manufacturing of Cold Drawn Seamless Pipes & Tubes, Precision Tubes, Square, Rectangular, Oval and Elliptical Tubes.
Learn MoreMetal pipe two-roll skew rolling piercer is the key deforming machine to make seamless pipe. Some hollow pipes after piercing often used to make cold drawn tubes or cold rolled tubes of high-end high precision pipe; some other hollow pipes go on elongating, sizing, straightening until get finished seamless pipes. The raw material can be steel
Learn MoreCold working in two ways: one is the drawing method, the pipe is drawn through a die to extubation, the steel pipe is tapered, elongated; Another method is to cold rolling. A seamless steel pipe cold working of steel can be improved dimensional accuracy and finish machining, and the like to improve the mechanical properties of the material.
Learn Morea steel with a high alloy content and high strength, while the cold-rolled steel is a low-carbon low-alloy steel, which can be used to improve the strength and ensure . the surface quality of the material by cold rolling. The difference between cold drawn seamless steel pipe and hot rolled seamless steel pipe is different from that of the plate.
Learn MoreUSES: it is widely used in the hydraulic system in steel tube, injection molding machine in steel tube, hydraulic press in steel, shipbuilding, steel tube, EVA foam hydraulic machinery, precision hydraulic steel pipe cutting machine, shoe-making machinery, hydraulic equipment, high pressure tubing, hydraulic tubing, card sets of joints, pipe
Learn MoreSeamless pipes Execution Standard. We can makes and markets cold-drawn and hot rolled seamless steel pipes and cold-drawn special-section seamless pipes which are widely applied in the industries of petrochemical, boiler, automobile, mechanical, construction.

Learn MoreThe use of cold-formed steel members in building construction began in the 1850s in both the United States and Great Britain. In the 1920s and 1930s, acceptance of cold-formed steel as a construction material was still limited because there was no adequate design standard and limited information on material use in building codes.
