4 1/2"~20" Steel&Plastic Composite Thread Protectors

Steel&plastic thread protectors description:

Steel&plastic thread protectors are made of a threaded HDPE bumper, which absorbs the impact shocks and a steel shell rolled over the front edge, which insures a superior protection against hazard.

Steel&plastic thread protector is available either in the open end or closed end version, liftable or non-liftable. The liftable protectors allow moving of the tubes using hooking devices and in the same time keep the tube thread and coating undamaged. The closed end protectors may have an optional vent hole designed to keep the inner pressure equal to the outer pressure. The vent hole may also have a filter, which prevents the intrusion of the foreign particles.

The design of the steel&plastic thread protector (steel shell and high density polyethylene bumper) ensures the protector integrity within the temperature range given by the API 5CT standard (-46ºC÷66ºC). Their design allows easy setting and removing using a tube wrench.
