Ultralarge-diameter axial hollow pipe socket with diameter of 1500mm and forming process

Abstract

The invention belongs to the technical field of drainage engineering, and provides an ultra-large-diameter axial hollow pipe socket with the diameter being 1500 mm and a forming technology. The axial hollow pipe socket comprises a pipe body with the diameter being 1500 mm, the pipe body is provided with a plurality of axial through holes, the end of the pipe body is provided with a socket section, the socket depth of the socket section is 380-700 mm, the socket section comprises a chamfering part, a socket matching part and a sealing part, and the chamfering part is provided with a plurality of through holes; the sealing part comprises a bulge connected with the bell mouth matching part, the angle of the chamfering part is 15-45 degrees, the length of the bell mouth matching part is 176-300mm, and the length of the sealing part is 200-400mm. The bell mouth not only can be conveniently produced in a standardized manner, but also has higher socket and spigot reliability; the forming technology comprises the technological processes of heating, pipe feeding, sealing ring sleeving, forming, vacuum suction, cooling, pipe drawing and the like, the standard axial hollow pipe socket can be produced in cooperation with forming equipment, the production efficiency is high, the product quality is good, and the production requirement can be fully met.

Description

technical field [0001] The invention belongs to the technical field of drainage engineering, and relates to a hollow pipe, in particular to an axial hollow pipe socket with a diameter of 1500 mm and a super-large diameter and a forming process. Background technique [0002] Water supply and drainage engineering mainly solves the problems related to water intake and drainage based on the principles of hydrology and hydrogeology, such as the principle of hydraulics to solve the transportation of water, and the principles of physics, chemistry and microbiology for the treatment and inspection of water quality. With the continuous improvement of the level of urbanization, water supply and drainage engineering, environmental engineering, water resources engineering and environmental science intersect and develop together. Drainage pipes used in water supply and drainage projects can be used to discharge urban sewage, which is an indispensable part of the normal operation of the c...

Problems solved by technology

However, although small and medium-diameter (DN630 and below) drainage pipes have been widely used in my country, the research on super-large-diameter drainage pipes with a diameter of 1.5m is still in its infancy, especially the lack of special research and design on 1500mm drainage pipe joints, and Supporting socket forming process with high production level
