Steel pipeline is used to transport the oil, gas and water drawn out of the ground to the oil and natural gas industry enterprises through the pipeline. The pipeline includes seamless pipe and welded steel pipe, with plain end,beveled end, threaded end and socket end; API 5L seamless steel pipe steel grades: gr.b, X42, X46, 52, X56, X60, X65, X70,etc. Its connection modes are welding, coupling connection, socket connection, etc.
