Advantages:Â

body

straightness
4. Tapered threadsÂ
Raw
materials:Â
Tangshan Jinshi only choose the best
steel tubes in the market to manufacture our rods and pipes. Spot
check will be conducted after the steel tubes delivered to company.
We will make sure the compositions and specifications match the
inspection report form the suppliers.Â
Heat treatment
control:Â
Heat treatment will greatly improve
the material strength and increase the thread wear life of the rods
and casings. We conduct either tru-wall or both ends heat treatment
to the tube body. After heat treatment, strength, hardness,
straightness and concentricity of the treated tubes will be tested
in our lab.Â
Thread opening process:Â
Accuracy of threads will determine
the use effects and life time of drill rod and
casings.Â
CNC latches and form cutter are used
in thread opening processing to minimize error made by anthropic
factors.Â
Additional thread treatment:Â
Surface of the threads will be
cleaned to remove burr adhered after threads are
opened.Â
Afterwards, the tread surface will
be phosphated to improve surface conditions.
