The oil industry is a large number of industries that use oil pipes, and the oil industry occupies an important position in the petroleum industries:
1, the oil pipeline is large, spend more money, save money, reduce costs of great potential. The oil well pipe consumption can be calculated according to the annual drilling scale. According to China's specific situation, in general, each drilling 1m need well pipe 62kg, which casing 48kg, tubing 10kg.
Drill pipe 3kg, drill collar 0.5kg;
2, the mechanical and environmental behavior of petroleum pipe has an important influence on the use of advanced technology and increasing efficiency of oil industry.
3, the oil pipeline failure loss is huge, its safety reliability and service life is very important to the petroleum industry.
