Embodiment Construction

[0017] As shown in Fig. 1, the polyethylene winding wall-shaped pipe of the present invention is a hollow rib pipe spirally wound outside the inner polyethylene pipe wall 1, and the hollow rib pipe is composed of a PP skeleton pipe coated with a polyethylene layer. The rib tube has two layers. The rib tubes of each layer are arranged at intervals, the second layer of rib tubes 3 is superimposed and wound on the first layer of rib tubes 2, and the rib tubes 3 and rib tubes 2 are arranged tangentially in the shape of a character. fixed by welding.

[0018] The pipe material of the present invention can be provided with a socket at one end and a socket at the other end, a circle of electric heating elements are embedded in the inner wall of the socket, and both ends of the electric heating element protrude from the inner wall of the socket. Setting the socket and the socket can make the operation of the pipe connection more convenient.

Abstract

The invention discloses a high-density tube in the shape like a Chinese character 'pin' with a polyethylene winding structure wall and a production process thereof. The tube disclosed by the invention has the structural characteristics that hollow finned tubes are spirally wound outside the wall of a polyethylene tube; the number of the finned tubes is more than one layer; each layer of the finned tubes are arranged at intervals; the outer layer of the finned tubes and the inner layer of the finned tubes are tangentially arranged in the shape like a Chinese character 'pin'; and the tangential finned tubes are welded and fixed. In the invention, raw materials can be saved, and the product cost can be lowered. Compared with the prior art, under the conditions of the same tube diameter and the same tube weight, the tube disclosed by the invention has greatly enhanced ring stiffness and strong service reliability and can be widely used in the fields of rain and sewage drainage engineering, chemical drainage and the like.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a polyethylene winding structure wall-shaped pipe and its production process. Background technique [0002] At present, the existing polyethylene winding structure wall pipes are produced according to the requirements of the national standard GB / T 19472.2-2004, and the B-type structure wall pipes are pipes with smooth inner surface and hollow spiral ribs on the outer surface. The wound rib tube can be multi-layered, the inner rib tube is wound with zero pitch, and the outer layer of rib tube is wound at intervals, and the flat belt needs to be laid at the same time when the rib tube is wound. For pipes with this structure, in order to ensure equidistant winding of the outer ribbed tube, the diameter of the inner ribbed tube should not be too large, otherwise the winding position of the outer ribbed tube will be affected due to the deep corrugation formed on the surface of t...
