Oil and Gas Applications

Oil and Gas
Steel pipes play a very important role in the oil and gas industry from extraction to transmission. Because of its strong performance, corrosion resistance, high and low temperature resistance, etc., it has become the preferred material in the oil and gas industry.
Mining: drill pipe, casing, tubing.
The drill bits used for mining, the pipelines that carry oil and gas to the surface, and the wellbores that protect the pipelines from collapsing, are all made of steel pipe.
Transport: In the process of oil and gas transport, need to overcome the pressure, temperature, strength, ductility, corrosion and other difficulties, steel pipe with its weldability, chemical stability, material diversity size flexibility, competent for this difficult task.
