Abstract

The invention discloses a water pipe butt joint method, which comprises the following steps: a. end part treatment: cutting the water pipe to make the end surface vertical to the axis; heating the iron plate A to 200 ℃, respectively attaching and placing two water pipe ends on the iron plate A, and heating for 2min until the water pipe ends are in a semi-molten state; b. and (3) flanging treatment: heating the iron plate B to 50 ℃, respectively attaching and placing two water pipe ends on the iron plate B, and then extruding the water pipes along the axis in the direction of the iron plate B to form turned edges on the water pipes and ensure that the turned edges are perpendicular to the water pipes; c. hot melting and butt joint: heating the iron plate A to 300 ℃, then attaching the iron plate A to the flanged end face of the water pipe for heating, wherein the heating time is 10s, taking down the iron plate A, aligning the axes of the two connected water pipes, applying an external force of 200N to fuse the flanged end faces of the two connected water pipes together, and completing the butt joint after the flanged end faces are completely cooled and solidified. The invention does not need to connect fittings, has simple working procedure and low cost.

Description

Water pipe butt joint method
Technical Field
The invention relates to a water pipe butt joint method.
Background
The length of the water pipe is not enough, and the water pipe needs to be butted and lengthened frequently, and the existing plastic water pipe adopts a connector connection mode; the joint connection cost is higher, and the pressure-bearing capacity of the water pipe joint is poor, and the condition of leakage is easy to occur.
In comparison, hot melt butt joint does not need to connect fittings, the process is simple, the cost is low, and the strength of the welding joint is superior to that of the water pipe.
Disclosure of Invention
The invention aims to provide a water pipe butt joint method which is suitable for families and has low cost and simple process.
The technical scheme adopted by the invention for solving the technical problems is as follows: the water pipe butt joint method comprises the following steps:
a. end part treatment: cutting the water pipe to make the end surface vertical to the axis; heating the iron plate A to 200 ℃, respectively attaching and placing two water pipe ends on the iron plate A, and heating for 2min until the water pipe ends are in a semi-molten state;
b. and (3) flanging treatment: heating the iron plate B to 50 ℃, respectively attaching and placing two water pipe ends on the iron plate B, and then extruding the water pipes along the axis in the direction of the iron plate B to form turned edges on the water pipes and ensure that the turned edges are perpendicular to the water pipes;
c. hot melting and butt joint: heating the iron plate A to 300 ℃, then attaching the iron plate A to the flanged end face of the water pipe for heating, wherein the heating time is 10s, taking down the iron plate A, aligning the axes of the two connected water pipes, applying an external force of 200N to fuse the flanged end faces of the two connected water pipes together, and completing the butt joint after the flanged end faces are completely cooled and solidified.
The invention has the beneficial effects that: the process is simple, the cost is low, the strength of the welding joint is superior to that of the water pipe, and the water pipe is suitable for household use.
