Embodiment Construction

[0010] attached by figure 1 It can be seen that the present invention includes the steel sleeve 2 and the plastic inner lining 1 provided outside the steel sleeve 2, the top of the steel sleeve 2 is provided with an inwardly stretched arc, and a shoulder 3 is provided between the arc and the plastic inner liner 1. The bottom of the plastic lining 1 is provided with an inwardly recessed back cover 4, and a transition platform 6 is provided between the back cover 4 and the top of the steel sleeve 2 near the shoulder 3, and the depth of the back cover 4 should be greater than 1% of the overall height of the protective cover. / 2, so that the spreader is more tightened during hoisting. The inside of the plastic lining 1 and the outer wall of the steel sleeve 2 are provided with threaded threads 5, which are used to cooperate and connect with the protected steel pipe.

[0011] It should be noted that the embodiments described in the present invention are only preferred modes, and a...

Abstract

An external thread protector with a hangable bottom cover relates to a protection kit for a steel pipe head. It includes a steel sleeve and a plastic inner lining set outside the steel sleeve. The top of the steel sleeve is provided with an inward stretching arc, and a shoulder is provided between the arc and the plastic inner lining. The plastic inner lining is provided with an inward transition to the bottom. Recessed back cover, a transition platform is provided between the bottom cover and the top of the steel sleeve near the shoulder, and threads are provided on the contact part between the plastic lining and the outer wall of the steel pipe, and the beneficial effect is that the protective cap is sleeved on the end of the steel pipe , so that the end of the hoisting tool is clamped in the bottom cover groove of the protector, and it will not fall off during hoisting, which is safe and reliable.

Description

technical field [0001] The invention relates to a protection set for a steel pipe head. Background technique [0002] During the transportation of the steel pipe, it is very easy to cause damage to the pipe end. In order to protect the pipe end, a pipe cap, that is, a protector, is generally placed on the pipe end. There is also a steel-plastic combination pipe cap with a plastic lining on the outside of the steel sleeve. Due to the buffering effect of the plastic, the protection effect is ideal. However, when the steel pipe is hoisted and transported, the existing protector cannot be hoisted because the spreader needs to be clamped at the end of the pipe. Contents of the invention [0003] The invention provides an external thread protector with a hangable bottom cover, which enables the steel pipe on which the protector is installed to protect the pipe head and is convenient for hoisting. [0004] In order to achieve the above object, the technical scheme that the pres...
