Design production capacity of 750000 t. Mainly used for continuous rolling pipe production. Plus the tubing of straight welded casing steel plant in Baoji, and a number of non professional factory with light tubes, production capacity is more than 850000 t.

The consumption of oil well pipe is about 21% ~ 25% of the total consumption of seamless steel pipe. 90's consumption of 75 ~ 900000 t. 1997 apparent consumption of 800000 t to 920000 T, 1998. 1998 domestic oil well pipe 660000 T, the domestic market share of 72%. Estimated consumption in 2000 was less than 1000000 t. Production capacity and apparent consumption of basic level. Due to the high performance of the supply of products is difficult, its actual output is not enough, it is still necessary to import.

The required specifications can be supplied. But the oil casing steel grade is only J55, N80, P110, J55,, N80, 85% or more, from the actual needs of more high steel grade has a large distance.

Technical progress of petroleum industry and pay attention to economic benefits, promote the casing to the small diameter (diameter 139.7mm) transfer. Sometimes not used in the surface casing, technology, or pipe instead of welded pipe. The surface casing pipe has become inevitable, the oil consumption must be reduced by the seamless steel pipe in the same footage case.
