What is the material of seamless steel tube?

　　The seamless steel pipe is made of ordinary and high-quality carbon structural steel (Q215-A to Q275-A and 10 to 50 steel), low alloy steel (09MnV, 16Mn, etc.), alloy steel, stainless acid and acid resistant steel.

　　Seamless steel tubes have hollow sections and are used in large quantities as pipes for transporting fluids, such as pipes for transporting petroleum, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe has a lighter weight when it has the same bending and torsional strength, and is an economical section steel. The material of the seamless steel pipe is different and its use is different.

SMLS steel pipe for Tanzania Gas pipeline project

图片
Project location: Tanzania Product：SMLS steel pipe Specification：168.3mm*14.27mm*SDR Standard and material：API 5L X52N PSL2 Application: Gas pipeline project In the last week of September, we received a new inquiry from regular customer who stated that it would take 4 weeks for delivery, including anti-corrosion. We learned that the fast delivery is most important point for this order. Xinyue people responded the fastest. Due to this order is for X52N PSL2 G high-grade seamless pipes, the stock quantity cannot meet the quantity of the entire order. With the strong resource integration ability of Xinyue, we found the production schedule of the steel pipe factory within 3 days and quickly organized new production. The customer arranges full process supervision from end customers, contractor customers, intermediate customers, and third parties from raw materials to the factory. During the supervision process of steel pipe production, they all witness the online UT test, Hydrostatic test, ...

Treatment method of steel pipe welding slag inclusion

What is welding slag inclusion? Welded pipe slag inclusions are slag that remains inside the weld. Welding slag inclusions are generally divided into two categories: The first category is metal slag inclusions. The second category is non-metallic slag, which refers to the slag remaining in the weld after welding, including electrode coating or flux, sulfide, oxide and nitride. According to its formation, it can be divided into point-like slag inclusions, linear slag inclusions, chain-like slag inclusions and dense slag inclusions. Slag inclusions will reduce the plasticity and toughness of steel pipe welds, and slag inclusions with sharp corners will cause stress concentration at the tip, and the tip will develop into a crack source, especially in welds with a large tendency to air quenching. Under the action of stress on the steel pipe, cracks will first appear at the slag inclusions in the weld and develop along the way, resulting in a decrease in strength and cracking of the weld. T...

ERW Steel Pipe Deliver to Argentina for oil and gas pipeline

图片
Project location：Argentina Product：ERW Steel Pipe Standard and material：API 5L PSL2 46th GR.X60M Specifications： OD: 457.2mm WT: 9.52mm Lenght:12M Application：oil and gas pipeline In the steel industry, customer demands vary, but quality and delivery time are always the most critical factors. Recently, Xinyue successfully provided a high-quality ERW pipe solution for a customer, and the entire process took only half a month, perfectly demonstrating our ability to respond quickly and execute efficiently. Although the customer’s order quantity was small, the steel grade requirements for the pipes were very high, and the supplier had to be listed in the client’s approved supplier directory. Facing such strict requirements, Xinyue mobilized all available resources and actively engaged with major suppliers. Ultimately, we successfully sourced BaoSteel’s inventory, which perfectly met the steel grade and quality requirements, and ensured on-time delivery. From receiving the inquiry to finali...
