岩心管钻杆接头、沉淀管接头和三翼钻头过去都用元钢墩制造，这样不但浪费材料，同时制造工艺也很繁杂，以岩心管钻杆接头为例，要经过三道工序：锻、车、铣，才能制成成品。现根据苏联专家巴拉巴建议利用无缝钢管来制作，不但能保证使用安全，而且还节省了大批材料，并且简化了制造工艺过程。 Core pipe and pipe fittings, pipe fittings and three-wing drill pipe pier past the use of steel pier manufacturing, so not only a waste of materials, while the manufacturing process is also very complicated, the core pipe drill pipe joints, for example, to go through three processes: forging, Car, milling, can be made into finished products. Now made using seamless steel pipe according to the suggestion of the Soviet expert Baraba, it not only ensures the safety of use, but also saves a large amount of material and simplifies the manufacturing process.
