Product Description Product Description Heavy Weight Drill Pipe Heavy weight drill pipe (HWDP) is usually run in between the drill collars and the drill pipe in order to prevent fatigue of the drill pipe in the vertical drilling industry. Heavy weight drill pipe is also utilized in the horizontal directional drilling (HDD) industry for added strength in high stress situations. Heavy weight drill pipe (HWDP) may be used to make the transition between the drill collars and drill pipe. The function of the HWDP is to provide a flexible transition between the drill collars and the drill pipe.Heavy Weight Drill Pipe(HWDP) is made from AISI 4145H Alloy steel, fully heattreated, all physical properties conform with API Spec 7-1 latest edition.Non-API standard type of drill collars are also available as per specificationCold-rolled thread rootsIntegral forging and welded type for optionsHard banding and internal coating can be done as per client's requestMaterial: AISI 4145H and Non-magnetic Material Standard: API SPEC 7-1 and NS-1Introduction:Heavy weight drill pipe has a "center upset", also known as wear pad, that increases tube life by protecting the tube from wearing on the outer diameter by keeping the tube away from the hole wall. It also reduces hole drag and differential sticking problems. The walls of heavy weight drill pipe are thicker and have longer upsets compared to conventional drill pipe, as well as being stronger with high tensile strength.Application:Heavy weight drill pipe (HWDP) is usually run in between the drill collars and the drill pipe in order to prevent fatigue of the drill pipe in the vertical drilling industry.
