钻杆使用的钢材不同，价格也会不一样。 我们钻杆采用优质地质专用合金钢管

The steel used for the drill pipe is different, and the price will be different. Our drill pipe is made of high-quality geological special alloy steel pipe (R780, DZ50). The drill pipe joint is made of high-quality alloy structural steel (42CrMo) and treated with real air conditioning quality, which greatly improves the fatigue resistance and shear strength. The other company should use ASI materials. If you want ASI material, we can also follow the price of another company.

The price of the drill pipe will vary depending on the steel used. Our drill pipe uses high-quality geological special alloy steel pipe (R780, DZ50), drill pipe joint sizzle high-quality alloy structure steel (42CrMo), to be treated with real air conditioning quality, greatly improving the strength of anti-fatigue and anti-shear strength. The other one should use ASI materials. If you want ASI material, we can also price another one.

The steel used for drill pipe is different, so is the price. We use high-quality geological alloy steel pipes (r780, dz50) and high-quality alloy structural steel (42CrMo) for drill pipe joints, which are treated by vacuum quenching and tempering, greatly improving the fatigue strength and shear strength. The other one should be ASI. If you want ASI material, we can also follow the price of another one.
