Spiral Drill Collar Of Application To Oil Drilling - Chinaprice: contact company for price
special steel of each chemical element control is quite
tight, after a medium frequency induction heating quenching
and tempering, from 1 "below the surface of tube body can
ensure the brinell hardness of 285-341 - hb. Charpy impact
energy reaches more than 54 j.
2.Spiral Drill Collar
Spiral drill collars are widely used because its own
features, the special spiral drill collar can reduce the
contact area of wall and pipe body, thereby avoiding the
phenomenon of "sticking" of the drill string.
Type A (cylindrical) : using ordinary alloy steel
manufacturing, the tube is circular cross section inside and
outside the drill collar.
Type B (spiral) : using ordinary alloy steel manufacturing,
pipe surface with spiral groove drill collar in vitro.
C (no magnet) : with very low permeability of stainless
steel manufacturing, pipe body inside and outside all is
circular cross section of the drill collar.
3.Material:AISI 4145H MOD
The hole diameter: 101 mm
Application: oil drilling
Elevator slot depth and the size of the slip groove depth
according to the nominal outer diameter of the drill collar
