Steel-Plastic Protectors:

External steel inner plastic protector is a common type of protector used by oil pipe manufacturers at present. The structure is to press in or insert the plastic bushing with the crimped steel ring, and then process the thread with the numerical control machine tool after pressing. Protector has high strength, especially impact strength. Because threads are processed by CNC machine tools, their accuracy is higher. The anti-vibration and slippage ability of protector is higher than that of other types of protectors in the transportation process. The threads of protectors can also be processed according to the special requirements of the pipe manufacturer. The outer steel inner plastic protector is also easy to recover. Its only disadvantage is that the manufacturing cost is higher than other types of protectors.
