Geological tube is steel pipe that using core drilling for the geological department, which a hollow cross section, surrounded by long geological drilling joints with steel pipes.
Geological Drilling Pipe
Geological pipe (YB235-70) with a hollow cross section, a large number of pipes, for conveying fluids such as the transportation of oil, gas, gas, water and some solid materials, pipes, etc. By end-use can be divided into the drill pipe, drill collars, the core pipe, casing and precipitation tubes.
要探索地下岩石结构，在地质管，地质钻管，地下水，石油，煤气和矿产资源的实际应用中，采用钻机钻井井。石油，天然气，采矿不能与钻井，地质钻孔和石油钻井无缝钢管，钻井设备，包括芯外管，芯管，套管，钻孔管。
Drilling tube deep into the depth of several kilometers strata, the working conditions are extremely complex, the drill pipe to withstand tension and compression, bending, torsion, and the uneven impact load stress, but also by the mud, rock wear, therefore, the requirements of the pipe must have sufficient strength, hardness, wear resistance and impact toughness.
规范，标准和识别Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.
Our team is highly trained and experienced in servicing and producing all types of steel supplies.
