All of the connections are strictly in accordance with API Standard, which have stress relief groove and are cold rolled.
The flank of thread is phosphatized or plated copper, coated with thread and equipped with thread protector. It is mainly the spiral blades (usually three blades, also can be four blades will according to customers' requirements), which rub against the borehole wall.
The working surface of the blade is hard faced.
The hardfacing type we can provide are HF1000, HF2000, HF3000, HF4000, HF5000, HF6000. It is preferred operation that tungsten carbide inserts are cold inset into the working surface of blades including its bevels.
Braze welding tungsten carbide grains are also adopted according to customers' requirements.
ALSO WE CAN SUPPLY DS-1 and NS-1 STANDARD STABILIZER.
We also can make the Impact value under -20°C(negative) low temperature according to the requirements of clients. The average impact value is about 30J.(This only for 4145H Mod.)
