Description
Designed to withstand extreme drilling conditions, heavy weight drill pipe (HWDP) offers superior tensile strength, enhanced torque capabilities, and improved weight distribution. RIGRS HWDP is manufactured by a new wall-thick steel pipe and we could offer a variety specification of HWDP.
Seamlessly integrating with the drill string, HWDP ensures optimal weight management, reducing vibration, and maximizing drilling productivity. Experience the power of HWDP for unmatched drilling success.
We can supply integral HWDP from 3 1/2” to 6 5/8”. Also we can supply friction welded HWDP, which is assembled with AISI 1340 steel pipe and AISI 4145H or 4137H tool joints. Hardbanding type include ARNCO 100XT/150XT/300XT350XT ARNCO series, DURABAND and TCS series. Internal coating services include TC2000, TC2000P and TC2000SS as customer needs.
Benefits & Features
- A centre 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 machiningand to help prevent galling upon initial make-up;
- Thread roots are cold rolled on APl and H-90 connections, and pressed steel thread protectors aresupplied for standard connections;
- Hardbanding and InternalCoating can beprovided on customer’s request;
Heavy weight drill pipe is a type of drill pipe whose walls are thicker and collars are longer than conventional drill pipe.
Heavy weight drill pipe was developed as an intermediate weight drill string member. It was originally developed for three reasons:
- As a transition member to be run between heavy weight drill pipe and drill collars.
- As a flexible weight member to be run in directional drilling.
- As a weight member on small rigs, drilling small diameter holes.
More recently, with the advent of horizontal drilling, it has found a new application being used in the curved portion of the hole below the drill collars.
