Manufacturing method of integrally shaped pipe having connecting part

Abstract

A technology for manufacturing the integrally formed tube having joint part includes such steps as preparing an elastic tube according to the shape of target tube, sleeving it on a forming rod, assembling mould to form a cavity between the inner surface of mould and forming rod, pouring thermoplastic resin in the said cavity, demoulding and removing forming rod.

Description

technical field [0001] The invention relates to a method for manufacturing an integrally formed pipe, in particular to a method for manufacturing a pipe material that can replace a pipe joint by integrally forming a plurality of branched elastic pipes. Background technique [0002] In some machinery and equipment, especially chemical equipment, various pipeline structures are involved. Among them, an elastic pipe is often used to transport liquid or gas. When multiple elastic pipes (such as bifurcations) need to be connected, Or when it is necessary to connect two elastic tubes with different diameters, or even to connect the elastic tube and a functional plastic device, the existing method is to use a pipe joint, and the elastic tube is sleeved on the pipe joint, because the elastic tube has a certain expansion capacity. , When the pressure in the pipe is large, leakage is easy to occur, and even falls off the pipe joint. In order to prevent the...

[0002] In some machinery and equipment, especially in chemical equipment, various pipeline structures are involved. Among them, an elastic tube is often used to transport liquid or gas. When it is necessary to connect multiple elastic tubes (such as bifurcations), Or when it is necessary to connect two elastic tubes with different calibers, or even connect the elastic tube with a functional plastic device, the existing method is to use a pipe joint to sleeve the elastic tube on the pipe joint, because the elastic tube has a certain expansion ability , when the pressure inside the pipe is high, it is easy to leak and even fall off from the pipe joint

In order to prevent the leakage of liquid or gas, the connection between the elastic pipe and the pipe joint is required to be reliable. In order to solve this problem, in the prior art, fastening chucks are often used to fix it, or adhesives are used to bond it, and heat-shrinkable tubes are also used to heat Shrinked and closed, however, leakage will still occur in this way, and at the same time, due to the need for fastening operations at each connection of the pipe joint, as the number of connected pipelines increases, the work intensity increases, which also leads to operating costs increase, and even the event that the operator missed the fastening operation
