We customize any and all API specified drill pipe. Our drill pipes are available in different sizes from 2-3/8 OD with a NC26 rotary connection to a 6-5/8 OD with a 6-5/8 FH rotary connection. Joiners from 3-3/8 OD 1- 3/4 ID to 8-1/2 OD 4/14 ID depending on your specifications.
Our drill pipes threads are turned in a spindle bore making for the best finish and accuracy.
Drill pipe is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses.
Drill stems must be designed to transfer drilling torque for combined lengths that often exceed several miles down into the Earth’s crust, and also must be able to resist pressure differentials between inside and outside (or vice versa), and have sufficient strength to suspend the total weight of deeper components.
Wire rope sheave is usually used for lifting large objects for many different industries, depending on the application, cast iron gives the wire rope a longer life but a short life for the sheave whereas cast steel sheaves have a long life and the rope as well.
Our sheaves come in a variety of different sizes as with our bearings, bushes and seals meeting your specific requirements.
Wire rope sheaves from 40” to 120” diameter.
