We adopts famous domestic large steel enterprises production of
material to produce drill pipe, and heat treatment of materials by
using an integrated multi-processing furnace, profession CNC
machining was applied in all of the connection thread processing,
all the treads are configured thread gauge, which are in accordance
with international standard, internal thickening technology has
carried on the tempering process after friction welding, so the
processing quality of drill pipe is stable, reliable, use cycle
greatly extended. We can process different length, diameter and
wall thickness and material of API standard thread rod, we also can
design and manufacture drill pipe according to customers’
requirement of the material, length, wall thickness and connect
thread.
