Heavy Weight Drill Pipe (HWDP) is an intermediate weight drill stem component which is used in conjunction with the drill pipes and drill collars. Our HWDP is available in standard, spiral and nonmagnetic designs. In some applications, heavy-weight drill pipes also can be used instead of the drill collars.
The HWDP is made from one-piece AISI 4145H modified quenched and tempered steel. It is designed for tough drilling environment in vertical and directional wells. Our HWDP is a transition member between drill collar and drill pipe. For directional holes HWDP provides weighton-bit and additional stiffness to prevent buckling.
Features and Benefits:
A center upset or wear pad to increase tube life, reduce hole drag and differential sticking problems;
Connections are completed (phosphate coated) to protect them from the elements after machining and to help prevent galling upon initial make-up;
Thread roots are cold rolled on API and H-90 connections. And pressed steel thread protectors are supplied for standard connections;
Hardbanding and internal coating can be provided on customer's request
Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.
