Non-Magnetic Heavy Weight Drill Pipe

Supplier: Drill collars, drill pipes, square kelly, hexagonal kelly, non-magnetic drill collar, integral heavy weight drill pipe, lifting sub, cross-over sub

The wall thickness of heavy weight drill pipe is between drill pipe and drill collar. Its structure is similar with drill pipe. It is made from premium alloyed steel. Its both tool joints and middle upset are welded hardbands. Technical parameters meet with API Spec7-1 standard.

1.Made of 4145H alloy structural steel. 2.Production complies with the provisions under the Standard SY/T 5146-1997. Connector screws comply with the provisions of the Standard API SPEC 7-1. 3.The tube section has a larger diameter at mid length to protect the heavy weight drill pipe from wear. 4.Hardbanding and Internal Coating can be provided on customer 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: 1. As a transition member to be run between heavy weight drill pipe and drill collars. 2. As a flexible weight member to be run in directional drilling. 3. 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.
