　　Welded steel pipe has superior ductility, integrity and convenient construction operability, suitable for buried laying, can be used for overhead, river inverted rainbow and pipe jacking construction.welded steel pipe has the advantages of simple production process, high production efficiency, more varieties and specifications, and less equipment. 　　In the first half of this year, China's external demand  Q235 SSAW Welded Steel Pipe for Gas and Oil  was more severe, mainly because the Trump Administration of the United States implemented trade protectionism, and trade frictions against China increased. To this end, the solution of policy-making departments will be to further expand Welded steel pipe, in order to ensure the expansion of Welded steel pipe and achieve the annual economic growth target. For example, at the meeting of the Political Bureau of the Central Committee held in the previous period, four measures were put forward to promote economic growth, among whic...

　　Because ordinary seamless pipes have poor antioxidant properties. If such pipes are placed outdoors directly, it will give seamless pipes the best conditions for rusting. Because the seamless pipe rusts very quickly under normal temperature and oxygen environment. If it rains from time to time, the pipe will rust quickly. Because of this kind of pipeline, it has very superior oxidation resistance. Even if the  API 5L PSL2 Carbon Steel Seamless Pipe for Oil And Gas  is placed in the open air environment, the pipe will not rust. It's easy to bring about some usage problems. In terms of hardness and compressive strength, it has certain advantages. But just a few years ago, many industries that used seamless pipes did not take seamless pipes as the main piping material. Why? This is because seamless pipes have many advantages, but also have a very obvious disadvantage. That is the ordinary seamless pipe, for the use of the environment, there are certain requirements. 　　If sea...

　　Hollow Sections are made of plain carbon steel Hollow Sections and low alloy Hollow Sections. Common carbon steel is divided into Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, etc. Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3 and so on. 　　Standard Classification of Hollow Sections Production 　　Hollow Sections are divided according to production standards: national standard Hollow Sections, Japanese standard Hollow Sections, British standard Hollow Sections, American standard Hollow Sections, European standard Hollow Sections and non-standard Hollow Sections. 　　Classification of Hollow Sections Surface Treatment 　　Hollow Sections are divided into hot galvanized Hollow Sections( ASTM A53 Hot Dip Galvanized Steel Hollow Section ), galvanized Hollow Sections, oiled Hollow Sections and pickled square pipes according to surface treatment. 　　Classification of Hollow Sections Use 　　Hollow Sections are classified according to their uses-square pipes for decoration,...

　　Now the carbon steel oil pipeline needed by the city can be collectively called hot-rolled carbon steel oil pipeline and cold-rolled carbon steel oil pipeline. Compared with hot-rolled carbon steel oil pipeline, the process of cold-rolled carbon steel oil pipeline is relatively complicated. Not only three continuous rolling, but also crack testing, cutting, and then into the final return process. When annealing cold-rolled carbon steel oil pipeline, pickling is unavoidable. During the pickling process, staff need to wear safety equipment. At the same time, we should carefully look at whether there are a large number of bubbles on the surface of steel pipe. If there are more bubbles, the quality of steel pipe can not meet the relevant requirements. 　　In appearance, the two kinds of steel pipe are also different. First of all, the length of cold-rolled carbon steel oil pipeline is a little shorter. ASTM A53 Gr.B Carbon Steel Oil Pipeline  strictly implement the national standard...

　　Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. 　　Cold rolled (dialed) seamless steel pipes include general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes. They also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and profiled steel pipes. 　　The outer diameter of hot-rolled seamless pipe is generally larger than 32 mm, the wall thickness is 2.5-75 mm, the diameter of cold-rolled seamless pipe can reach 6 mm, the wall thickness can reach 0.25 mm, the outer diameter of thin-walled pipe can reach 5 mm, the wall thickness is less than 0.25 mm, and the dimension precision of cold-rolled seamless pipe is higher ...

　　1. From the processing point of view: straight seam steel pipe is made of steel plate with a certain width into cylinder, and then welded to form, the equipment is relatively simple, and the productivity is also high. Spiral steel pipe is made by winding a certain width of steel plate into a cylinder, then welding, forming, equipment is more complex, at the same time, because the weld is much longer than the straight seam steel pipe, so the productivity is relatively low. 　　2. From the strength point of view: after welding, the internal stress of straight seam steel pipe distributes along the weld, while the internal stress of   ASTM A53 SSAW Sch 40 Spiral Steel Pipe   distributes uniformly along the axial and radial direction, which can better partially offset the pressure. So in terms of pressure resistance, spiral steel pipe is stronger.

　　Welded galvanized steel pipes with large diameter or thicker thickness are usually directly made of billet, while thin-walled welded pipes with small welded pipes only need to be directly welded through steel strips. Then after a simple polishing, the wire drawing can be done. Therefore, most of the smaller diameter welded pipes are welded by straight seam welding, while the larger diameter welded pipes are mostly welded by spiral welding. It has good mechanical properties, weldability, cold, hot working and corrosion resistance, and good low temperature toughness. 　　Key points for cutting off  API 5L Gr.B Galvanized Steel Pipe : 　　(1) To cut off the place, please wipe the oil, debris or soil on the surface of galvanized steel pipe completely with a cloth or soft cloth. 　　(2) It is necessary to select special stainless steel cut-off. 　　(3) The location of the cut-off should be coordinated with the construction drawings and site conditions, and the cut-off line should be ...

　　Seamless steel pipe is a kind of typical seamless welding pipe material. Because of this advantage, this kind of pipe material is superior to ordinary steel pipe. There are various kinds of steel pipes, and there are many material divisions. However, the most common one is still carbon steel. According to different purposes, the materials are adjusted to meet the needs. Seamless steel pipes emerge in such a market, and are constantly developing and improving. 　　There are many kinds of pipe materials, and  ASTM A106 Sch XS Carbon Seamless Steel Pipe  is just one of them. Compared with other kinds of pipe materials, the advantages of seamless steel pipe are very significant. First of all, this type of pipe material is seamless. Therefore, as the material used for pipeline transportation, the leakage probability will be minimized. Secondly, the advantages of seamless steel pipe in quality are also very significant. It is precisely because of these reasons that this kind of pi...

　　The heating furnace used in the production of seamless steel oil casing pipe is the annular heating furnace. In addition to this kind of heating furnace, there are other kinds of heating furnaces. According to the different manufacturing methods of seamless steel oil casing pipe, there are also differences in the specific heating methods. After the completion of heat treatment, further processing, including straightening, finishing and inspection, is needed to ensure that there is no The quality of seamless steel oil casing pipe can be kept at the highest level when it comes out of the factory, so the inspection steps are essential. 　　The demand for various seamless steel oil casing pipe accessory materials is also increasing, especially for various pipeline materials. From the current market environment, various types of pipeline materials have a wide range of types, different types of pipelines, and different fields of application. Among them,  API 5L X42 N80 Seamless Steel O...

　　The wall thickness of spiral steel pipe is usually the bottom difference. The bottom difference of general standard spiral steel pipe is 1mm, and the bottom difference of national standard spiral steel pipe is 0.5mm. Is the wall thickness after the bottom difference generally the actual wall thickness of spiral steel pipe? Actually not! 　　The wall thickness of the spiral steel pipe is 6mm, and the spiral steel pipe manufacturer orders 5mm strip steel for production in the steel plant. That is to say, the difference of the bottom thickness of the spiral steel pipe manufacturer just tells you that we use the difference of the bottom thickness of the strip steel to produce, rather than the actual wall thickness of the spiral steel pipe is the difference of the bottom thickness of the strip steel. In fact, the thinnest part of the spiral steel pipe is not 5mm, because the strip steel is 5mm thick Its wall thickness is not uniform, and its thickness is 4.8mm, 4.9mm, 5.0mm, 5.1mm and so ...

　　At present, the spiral steel pipe should be widely used in the water transmission project. Because there are many materials of spiral steel pipe, which one should be selected? Let's introduce it. 　　Due to the relatively small bearing pressure of water transmission pipeline, at present, the spiral steel pipe with Q235B material is mainly selected, and the executive standard is 5037 or 9711, which is commonly known as Q235B spiral steel pipe for drainage. 　　Material of  ASTM A106 28 inch SSAW Spiral Steel Pipe  for drainage: Q235A, q23b, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, Q345, L245, L290, X42, X46, X70, X80. The spiral steel pipe for drainage uses double-sided submerged arc welding technology. The weld is spiral. The diameter of spiral steel pipe for drainage is more than DN500, which is suitable for water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction and liquid transportation: wa...

　　The welding deviation of spiral welded steel pipe means that the welding position deviates from the welding center line. When welding, the welding angle deviates from the welding junction and is not welded along the weld. 　　In each standard, the welding deviation of  API 5L X42 Spiral Welded Steel Pipe  weld is also specified: 　　1. Spiral submerged arc welded steel pipe for low pressure fluid transmission pipeline, which is not specified in SY / t5037-2012 standard. 　　2. Technical conditions for delivery of welded steel pipes for oil and natural gas industry - Part 1: class a steel pipe GB / t9711-2011 PSL1 standard stipulates that as long as the non-destructive test proves that the weld is fully penetrated and fully fused, the welding deviation cannot be used as the rejection basis for spiral welded steel pipes, 　　3. Technical delivery conditions for oil and natural gas industrial transmission steel pipe part 2: steel pipe of class B GB / t9711-2011 PSL2 standard st...

　　Because the seamless steel pipe is round, when we say the specification of the seamless steel pipe, we all distinguish the specification of the seamless steel pipe by its diameter. 　　The diameter of seamless steel pipe is divided into nominal diameter, outer diameter and inner diameter. The nominal diameter is also called nominal diameter. It is represented by the letter DN. For example, the nominal diameter of seamlesssteel pipe with a nominal diameter of 200 is DN200 seamless steel pipe. Generally, the nominal diameter will appear in the design drawing, so as to determine the structural dimension and joint dimension of pipe, pipe fitting, valve, flange, gasket, etc. according to the nominal diameter, The nominal diameter is the specification title of the pipe diameter close to the inner diameter of the seamless steel pipe, but not equal to the inner diameter. In terms of the outer diameter, it is not difficult to guess that the outer diameter of the seamless steel pipe is the max...

　　When there is less cutting allowance reserved at both ends of seamless steel oil pipe, due to the structure of the detection device, the two ends sometimes cannot be effectively detected, and the end is the most likely part with cracks or other defects. If there is a potential crack tendency at the end, the welding heat effect during installation may also cause potential crack growth. Therefore, we should also pay attention to the detection of a certain area of seamless steel oil pipe after welding, and find the expansion of steel pipe end defects in time. 　　 API 5L X70 LSAW Seamless Steel Oil Pipe  is mainly used in pipeline transportation, which can be used to transport some fluids, such as some energy sources, etc. the transportation of oil and natural gas has been realized by relying on seamless steel oil pipe. In modern society, the application field and scope of seamless steel oil pipe once again make 16Mn seamless steel oil pipe widely used. The general purpose seamless ...
