Drill Pipe Casing

Product Description

Steel pipes for mining exploration are generally divided into several categories, including drill pipe, casing, core pipe and sedimentation pipe. Because the geological drill pipe and casing will work in some extreme environments, it must be able to resist external conditions including high pressure and high hardness, and must also be able to withstand high temperature conditions caused by friction, so the requirements for drill pipe casing are very high.

The material needs to have sufficient strength and hardness, as well as wear resistance and toughness. Based on the principle of using high-quality raw materials and strict processing technology, we ensure that the drill pipe casing can be used in different situations.

We offer W-series API drill pipe casing are made as per DCDMA standards, the most popular sizes are AW, BW, NW, HW and PW, which are widely applied in geotechnial drilling.
