Problems solved by technology

[0002] During the production process of plastic-lined steel-plastic pipes, port delamination occurs due to the different shrinkage rates of the two materials and plastic creep. All delamination starts from the port, which affects product quality.
The caps used in the existing plastic-lined steel pipes belong to the outsourcing structure. figure 1 As shown, when it is installed, it is set on the outer surface of the pipe end, and its protection has no meaning for the delamination of the plastic-lined layer; and because the end of the plastic-li...

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The pipe cap structure that the present invention adopts is as attached figure 2 , 3 As shown, including the bowl 1 and the outer edge 2, the outer surface of the bowl 1 is uniformly provided with reinforcing ribs 3, and the bottom of the outer surface of the bowl 1 is arched to form a concave part 4.

[0022] The operation of the present invention is as attached Figure 4 As shown, the bowl 1 is inserted into the port of the plastic-lined steel pipe 5, and the outer edge 2 covers the end face of the plastic-lined steel pipe 5, which supports the plastic-lined steel pipe through the evenly distributed reinforcing ribs 3 provided on the outer surface of the bowl 1. The adhesive layer of the tube 5, no matter how long the product is placed, the port will not be delaminated due to shrinkage, which improves the quality of the product. The design depth of the bow...

Abstract

The invention provides a treatment method suitable for carrying and storing plastic-lined steel pipes. Inwards concave pipe caps are inserted at two ends of the plastic-lined steel pipes, the pipe cap is bowl-shaped and comprises an inwards concave bowl body and a thin ring outer edge positioned at the part of a bowl opening, the external surface of the bowl body is approximately in fit with the pipe diameter of the plastic-lined steel pipe, and the thin ring outer edge covers the end face of the plastic-lined steel pipe. The treatment method effectively prevents ports of the plastic-lined steel pipes from being layered, overcomes the potential safety hazard in a process of carrying products and inconvenience in the operation, and improves the quality of the product and work efficiency.

Description

technical field [0001] The invention belongs to the field of auxiliary processing of plastic-lined steel pipes, and in particular relates to a processing method suitable for handling and storing plastic-lined steel pipes. Background technique [0002] During the production process of the plastic-lined steel-plastic pipe, the end delamination occurs due to the different shrinkage rates of the two materials and the creep of the plastic. All delamination starts from the end, which affects product quality. The caps used in the existing plastic-lined steel pipes belong to the outsourcing structure. figure 1 As shown, when it is installed, it is set on the outer surface of the pipe end, and its protection has no meaning for the delamination of the plastic-lined layer; and because the end of the plastic-lined steel pipe is blocked, it is difficult to drag and pack the pipe, especially Larger-sized composite pipes, because each of the large-sized pipes is very heavy, such as a DN65...
