Material AISI 4145H Sprial Drill Collar for Oil and Gas

 

Product Introduction
 

Spiral drill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from diffirential pressure. The drill collars are manufactired strictly according to API Spec7-1 and Standard SY5144. The drill collars are made of modified AISI 4145H chromium molybdenum alloy steel.

 

Our Spiral Drill Collar is made from AISI 4145H modified alloy steel, and completely meets the requirement of API Spec 7-1 and SY/T5144 Standard. It is a kind of drill collar which adds three dextrogyrate spiral groove on the outer circle of ordinary drill collar when processing, and the purpose is to reduce the area of contact and friction with the well wall, which can effectively prevent the pressure sticking. The single weight of the spiral drill collar is round about 4% lighter than the ordinary drill collar with the same specification, and the shape and thread of the both ends are the same with the drill collar.
