Drill pipe is the basic component of drill string. It is mainly used to supply torsional energy and drilling fluid to the bit. The drill pipe we supply covers full range of API, shell NS - 1 standard, also can be customized to use in complex well conditions. Internal coating and hardbanding is applied for drill pipe improve service life. The internal coating can resist the corrosion of hydrogen sulfide and carbon dioxide, thus reducing the cost of oilfield production. The hardbanding has great wear-resisting and wear-reduction performance. That can prolong the bit's life.
Our company lays emphasis on product quality. Product quality is controlled strictly according to API standard and customer's special requirement: appearance inspection, dimension inspection, chemical & physical properties inspection; performance test, NDT, strength test, tensile test, hardness test, welding zone test& inspection, etc. All the measures ensure our products qualified.
