API 5L seamless steel pipe is the seamless steel pipe of pipeline steel - API 5L seamless steel pipe of pipeline steel, seamless steel pipe pipeline steel material: gr.b, X42, X46, 52, X56, X60, X65, X70. The pipeline pipe is used to transport the oil, steam and water extracted from the ground to the oil and natural gas industrial enterprises through the pipeline pipe. The pipeline pipe includes seamless pipe and welded steel pipe, and its pipe end has flat end, threaded end and bell end; The connection mode is welding, coupling connection, socket connection, etc.
With the development of API 5L pipeline steel seamless pipe technology and the progress of forming and technology, the application scope of API 5L pipeline steel seamless pipe is gradually expanding, especially the advantage of API 5L large-diameter pipeline steel seamless pipe is more obvious. In addition to the cost factor, API 5L pipeline steel seamless pipe has occupied a leading position in the field of pipeline steel pipe, and the development of API 5L pipeline steel seamless pipe. In 2004, about 100000 tons of seamless pipeline pipes were exported. The steel grades include gr.b, X42, X46, 52, X56, X60, X65 and X70
