LSAW Steel Pipe

Project Site: South America Product: Seamless Elbow Size: 30 inch Standard & Material: ASTM A860/MSS SP-75 Application: Construction of oil pipelines Inquiry Time：2021.9 Contract Time：2021.10 ETD: 2022.1 ETA：2022.2 In September 2021, Xinyue received an inquiry for a new project from an regular customer in South America. The terminal is a famous oil company in South America. The required products are 3D large-diameter elbows of 90 degrees and 45 degrees, with a diameter of 30 inches. Xinyue repeatedly study the customer’s technical requirements, combined with various key information points, the product plan and technical documents were quickly submitted to the customer. After a month of detailed consultation, the customer placed the order to our company for production in October 2021. For the material of the elbow, Xinyue adopts the seamless steel pipe with good acid resistance. The basic pipe material can meet the performance after three heat treatment and debugging, also passed th...

　　A seamless elbow is a type of pipe used for turning a pipe. Among all the pipe fittings used in the pipeline system, the proportion is the largest, about 80%. Generally, different forming processes are selected for elbows of different material wall thicknesses. Currently. Seamless elbow forming processes commonly used in manufacturing plants include hot push, stamping, extrusion, etc. 　　The raw material of the seamless elbow pipe fitting is a round pipe blank, and the round pipe embryo is cut into a blank having a length of about one meter by a cutting machine, and is sent to the furnace for heating through a conveyor belt. The billet is fed into a furnace and heated to a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round billet is released, it is subjected to a through-hole punching machine. The more common perforating machine is a conical roller punching machine. This perforating machi...
