产品详情
KISN water well drill pipe is made for production and exploration water wells, in tube sizes from 76 mm to 140 mm with API 2-3/8 REG and NC series threads. The body is drawn from large-steel-mill material selected to resist fatigue, because a water well string is judged over years of repeated make-up and break-out, not over one hole.
Flush Profile, Cleaner Hole
The pipe runs a flush profile, so there is no shoulder for cuttings to pack against. Cuttings and returns move past the string instead of building up on it, which keeps the hole cleaner and reduces the torque needed to turn the string.
Internal Upset Forging
Pipe ends are heated by medium-frequency induction and thickened under high-tonnage hydraulic upsetting before the joint is made. This puts extra wall exactly where the load concentrates, and it is the reason the connection, not the tube, is no longer the weak point of the string.
Heat Treatment and Stress Relief
The tube is quenched and tempered to the grade your well calls for, and the weld is stress-relieved after friction welding so the joint and the tube behave as one. Stress relief is what keeps joint performance consistent from the first pipe to the last.
Threads and Interchangeability
Threads are cut to API 2-3/8 REG and NC26 / NC31 / NC35 / NC38 / NC40, so the string makes up with the standard tooling already on your rig and with equipment you already hold. Single and double wrench flats are available to suit how your crews handle the pipe.
Custom
Materials, diameters, lengths and wall thicknesses can all be produced to order. Tell us the well depth, the rig and the formation and we will match the pipe.
Where It Ships
Supplied to drilling contractors in Africa, Southeast Asia and the Middle East.

常见问题
What sizes of water well drill pipe do you make?
76 mm to 140 mm tube OD. Tube diameter, wall thickness, upset type, length and wrench flat are listed for each size on this page.
Which threads are used?
API 2-3/8 REG and NC26, NC31, NC35, NC38 and NC40. This keeps the string compatible with standard rig tooling.
Why does the pipe have a flush profile?
A flush profile leaves no shoulder for cuttings to pack against, so returns clear the hole more easily and the string turns with less torque.
Can you supply custom diameters, lengths or wall thicknesses?
Yes — materials, diameters, lengths and wall thicknesses can all be produced to order.
What is the minimum order and lead time?
Standard minimum order is 10 pieces, with a lead time of 10 days. Special specifications are made to order.
