Abstract

Disclosed is a thread protector structure with a reinforcing steel lining. The thread protector structure is used for protecting an external thread of the head of a steel pipe. The thread protector structure comprises a three-layer structure from inside to outside, the innermost layer is an inner plastic layer, the outermost layer is an outer plastic layer, and the steel lining is arranged between the inner plastic layer and the outer plastic layer. The steel lining is provided with a plurality of through holes. Connecting columns for connecting the inner plastic layer with the outer plastic layer are disposed in the through holes. The thread protector structure with the reinforcing steel lining has the beneficial effects that by means of the structure in the technical scheme, the strength of a protector is high, the protector is not prone to being damaged, and the excellent protecting effect on the screw thread of the end of the steel pipe is achieved.

Description

technical field [0001] The invention relates to a protector for protecting the outer thread of a steel pipe pipe head. Background technique [0002] During the transportation of steel pipes, it is very easy to cause damage to the external thread of the pipe end. In order to protect the external thread of the pipe head, a pipe cap, that is, a protector, is generally set at the pipe end. The PVC thread protector used in the past has weak impact resistance and is easily damaged, and sometimes fails to protect the pipe end thread of the steel pipe. SUMMARY OF THE INVENTION [0003] The invention provides a thread protector structure with a reinforced steel lining, which adopts the steel lining as an inner layer and plays a good role in strengthening the strength. [0004] In order to achieve the above object, the technical scheme adopted by the present invention is: [0005] A thread protector structure with reinforced steel lining is characterized in that it includes a thre...
