Heavy Weight Drill Pipe(HWDP)
Product Introduction In the drilling process, HWDP is a transition from a flexible drill pipe to a rigid drill collar. Moreover, it replaces drill collar to reduce friction in horizontal and extended reach wells.
• Reduces the stress concentration between the drill pipe and drill collar.
• Prevents sticking of drilling tool due to differential pressure.
• Reduces friction and torque.
• Mitigates the problem of excessive flexion on center wear pad
Hilong Drilling Tools is comm𓆉itted to the quality and technol🌌ogical innovation of HWDP. It continues to develop HWDP that meet special environments and drilling conditions.
Hilong HWDP Quality and Performance·The integral HWDP and welded HWDP are manufactured by quenching and tempering heat treatment process, which ensures that the HWDP body has better impact toughness.
Using MES and ERP systems, it can realize comprehensive information management of the entire process from order-to-shipment, including the entire manufacturing process, inspection and test acceptance, and product traceability.
· Pipe body 100% FLUT (longitudinal, transverse, ultrasonic thickness measurement) + Upset end 100% UT or 100% MPI, HWDP tool joints and welding zone 100% UT + 100% MPI.
· Options for improving the performanc💞e of HWDP: Increased length of tong space for HWDP tool joint, make and break, cold rolling of threads, spiral grooves on center wear pad, internal coating, and hardbanding.
HWDP Product Type·Integral HWDP and welded HWDP.
·Welded HWDP includes standard strength HWDP, high strength HWDP, sour services HWDP, and Hilong premium connection HWDP.
·Without spiral groove ওand with spi♚ral groove.
