ERW Steel Pipe

 　　1) The comprehensive mechanical properties are better than ferritic stainless steel, especially plastic toughness, not as sensitive to brittleness as ferritic stainless steel. 　　2) In addition to stress corrosion resistance, other local corrosion resistance is superior to ferritic stainless steel. 　　3) Cold working process performance and cold forming performance are much better than ferritic stainless steel. 　　4) The welding performance is also much better than that of ferritic stainless steel. Generally, no preheating is required before welding, and no heat treatment is required after welding. 　　5) The application range is wider than that of ferritic stainless steel. 　　Compared with ferritic stainless steel, the disadvantages of duplex stainless steel are as follows: high alloying elements and relatively high price, generally ferrite does not contain nickel. 　　 https://www.xysteelpipe.com/the-difference-between-duplex-2205-stainless-steel-pipe-and-ferritic-410-stainless-steel-...

 　　Tianjin Xinyue Steel Group has been serving customers all over the world by supplying carbon steel and low-alloy steel pipes, from airport construction, bridge construction, to oil transportation on sea. It is highly think of supplying pipe by customers and end users. 　　At the beginning of the year, three Egyptian customers visited our company. Due to the tight schedule, we mainly have a meeting on headquarters. By introducing the production process of carbon steel, stainless steel seamless, and welded pipes to customers, Clients know about our production and shipments on the spot. Customers are deeply impressed by our expertise. A trial order was placed that month. Although it contains seamless stainless steel and carbon steel, many specifications and few quantities. Xinyue took full advantage of its inventory and actively prepares goods for customers. The value and quantity was guaranteed to be shipped to customers on time. 　　When the goods arrive at the port, end user is very...

 　　Every project order has a bitter history. From receiving orders, raw materials, production to shipping port, every step, large or small, can not be smooth sailing. It is because of the experience and setbacks that we have learned more about the operation of project order. Our Xinyue team is not afraid of difficulties and perfectly overcomes the problems in every step. 　　From the third party's requirement that 100% ut test should be carried out at the weld of each steel pipe, and it is required to wait for 24 hours for UT detection, and then to Carboline, there is no stock in China due to insufficient paint. 　　According to ASTM A252 standard, there is no requirement for UT inspection in the standard, UT inspection after the steel pipe is cooled for 24 hours. However, in order to meet the requirements of customers and the third party, Xinyue is willing to cooperate with the third party to do UT inspection 100%.even it occurred over cost here. 　　As for the lack of paint, we need to...

 　　It has been nearly a year since the first cooperation relationship with this customer was established at the beginning of 2020. During one year, the customer has reordered 3 times. Highly recognized Tianjin Xinyue's quality control, resources, and ability to solve problems in a timely manner. There is no smooth sailing order. However, Xinyue relies on its own ability to make every order finally delivered smoothly. 　　The customer comes from Australia and has its own processing plant in Vietnam. After the pipes are processed, they all will be delivery and used in Australian local projects. Therefore, the steel grade has always been required to be high-steel grade C350 Australian steel grade. The biggest difficulty of this order is the specifications required are more than 5 different sizes, but the number of specifications is decades tons. The minimum order quantity for the single specification of the steel grade is generally 200 tons. Xinyue relies on its own experience in this i...

 　　Today we will talk about the difference between 3pe anticorrosive steel pipe and epoxy coal asphalt anticorrosive steel pipe. 3pe anticorrosion and epoxy coal asphalt anticorrosion are two commonly used forms of steel pipe outer wall corrosion protection. The anticorrosion effect of 3pe anticorrosion steel pipe is better than epoxy coal asphalt anticorrosion steel pipe. Why do we say that? 　　1. Service life 　　3pe anticorrosive steel pipe can generally be used for about 30-50 years, epoxy coal asphalt anticorrosive steel pipe service life is between 20 years. 　　2. Processing technology 　　The three main raw materials of epoxy coal tar anticorrosion are composed of epoxy coal tar primer and top coat, and cold coal entangled tape of epoxy coal tar. Two oil, epoxy coal tar asphalt anti-corrosion steel pipe application I is the use of epoxy coal tar tar paint on steel pipes, generally in the form of painting, epoxy coal tar tar paint combines epoxy resin with high mechanical strength,...

 　　The control of the wall thickness of seamless steel pipe is a difficult point in the production of steel pipes. The measures to improve the accuracy of the wall thickness in the production mainly include the following aspects: 　　1. Tube billet heating 　　Heating must be uniform, and rapid temperature rise and fall are prohibited. The temperature rise and fall should be kept steady and slow each time, and the maximum temperature rise and fall should not exceed 30°C. 　　2. Centering roller 　　Determine whether the centering roller is installed in place, adjust the center, opening angle and the opening size of the relevant core-holding roller to be consistent, and the center of the core-holding roller should be on the rolling line. 　　3. Rolling center line 　　Ensure that the rolling centerline of the piercing machine is consistent with the centerline of the piercing trolley, avoiding “up rolling” or “down rolling”, so that the tube billet maintains uniform force during piercing. 　　4. R...

 　　Last week, the mainstream domestic scrap steel market was stable and adjusted individually. Merchants were cautious about the market after the Spring Festival and adopted a "fast in and out" strategy. However, the overall arrival situation of steel mills was average, and the winter storage of scrap steel was basically over, depending on their own conditions. Adjust the purchase price within a narrow range. 　　Compared with the previous week, the average purchase price of scrap for key steel companies has increased by 5 yuan/ton for heavy scrap, 8 yuan/ton for medium-sized scrap, and 13 yuan/ton for aggregate scrap. 　　Entering February, scrap steel processing and distribution companies have been on holidays one after another, and the market is in a half-closed state. As the Spring Festival approaches and the prices of finished products continue to fall, the profits of steel mills are squeezed, independent electric arc furnace steel mills are not enthusiastic about production...
