China factory ASTM A106/ API 5L / ASTM A53 grade b seamless carbon steel pipe for oil and gas pipeline

Seamless steel pipe is a kind of economic section steel, which plays a very important role in the national economy. It is widely used in petroleum, chemical industry, boiler, power station, ship, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction, military industry and other departments.Seamless steel pipe with hollow section, a large number of used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid material pipeline. Is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, etc., has been widely used to make steel pipe. Shandong Liaocheng is known as the "capital of seamless steel pipe", such as Liaocheng seamless steel pipe factory production of large caliber seamless steel pipe. The standing resource materials are: 10#, 20#, 35#, 45#, 16Mn, 27SiMn, 40Cr, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, 45Mn2, etc.

The process flow

General seamless steel tube production process can be divided into cold drawing and hot rolled, cold rolled seamless steel tube production process generally more complicated than hot rolled, three-roll rolling tube billet must first, after the extrusion sizing test, if there is no response after crack on the surface of pipe have to be cut after cutting machine, cutting grow about a meter of billet. Then enter the annealing process, annealing to use acidic liquid pickling, pickling should pay attention to whether there are a lot of bubbling on the surface, if there are a lot of bubbling shows that the quality of the steel pipe can not meet the response standard. The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe, the wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe, but the surface looks brighter than that of thick-walled seamless steel pipe, the surface is not too rough, the caliber is not too much burr. The delivery state of hot rolled seamless steel pipe is usually hot rolled after heat treatment. After quality inspection, hot rolled seamless steel pipe should be strictly selected by the staff. After quality inspection, surface oiling should be carried out, followed by many cold drawing experiments. After hot rolling treatment, perforation experiments should be carried out, and if the diameter of perforation is too large, straightening should be carried out. After straightening, it is sent to flaw detection machine by transmission device for flaw detection experiment. Finally, it is put into warehouse after labeling and specification arrangement.

Hot rolled

Round tube billet → heating → perforation → three-roll cross rolling, continuous rolling or extrusion → tube stripping → sizing (or reducing) → cooling → straightening → water pressure test (or defect detection) → marking → storage Seamless steel tube is made of steel ingot or solid tube billet through perforation into capillary tube, and then made by hot rolling, cold rolling or cold drawing. The specifications of seamless steel pipe are expressed by the number of millimeters of outer diameter * wall thickness. Seamless steel tubes are divided into hot rolled and cold rolled (dial) seamless steel tubes. Hot rolled seamless steel tubes are classified into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes. Cold rolled (dial) seamless steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel pipe, special-shaped steel pipe. The outer diameter of hot rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-200mm. The diameter of cold rolled seamless steel pipe can reach 6mm, and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm and the wall thickness is less than 0.25mm.

Generally used seamless steel pipe is made of 10, 20, 30, 35, 45 and other high-quality carbon bonded steel 16Mn, 5MnV and other low alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other bonded steel hot rolled or cold rolled. 10, 20 and other low carbon steel manufacturing seamless pipe is mainly used for fluid pipeline. 45, 40Cr and other medium carbon steel made of seamless pipe to manufacture mechanical parts, such as cars, tractors stressed parts. The general use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel pipes are delivered in hot rolled or heat treated condition. Delivery is cold rolled hot and heat treated.

Hot rolling, as the name implies, rolling parts of high temperature, so the deformation resistance is small, can achieve large deformation. Taking steel plate rolling as an example, the thickness of continuous casting billet is about 230mm, and after rough rolling and finishing rolling, the final thickness is 1~20mm. At the same time, because the thickness ratio of the steel plate is small, the dimensional accuracy is relatively low, it is not easy to appear the shape problem, mainly to control the crown. For the requirements of the organization, generally through the control of rolling and cooling to achieve, that is, the control of finishing rolling rolling temperature, rolling temperature. Round tube blank → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage.
