1.Seamless Steel Casing Pipe:

We have four production lines for casing specially used for petroleum industry,with an annual capacity of 200,000 tons.We adopt the most advanced threading machines and numerical cotrol machining equipment.The test pressure of the hdrostatic testing machine is up to 70MPa.

2.ERW Casing Pipes

High dimensional precision.

Good flexibility.

High performance of impact resistance and explosion resistance.

The ERW casing uses hot rolled coiled plate, the tube blank is highly compact and has a high degree of grain size,which is better than seamless steel.

High productivity, low cost and efficiently elongating the life of oil wells
