Product Details
Casing Pipe or Casing Tube (W Thread) plays a very important role during drilling, it is design to pass the overburden formations or the formation need to use casing for drilling, for making sure the best performance, we use 4130 as the recommended raw material:
Size available:
BW casing 73mm, Thickness: 6.35mm
NW casing 88.9mm, Thickness: 6.35mm
HW casing 114.3mm,Thickness: 6.35mm
PW casing 139.7mm,Thickness: 6.35mm
Tubing
High quality alloy steel tubing;
Consistent concentricity, straightness and heat treatment;
All tubing available in DCDMA sizes.
Thread
Tapered, course threads (3 threads per inch) provides easy make and break;
Load efficiency of 30% provides sufficient strength for average applications.
