Problems solved by technology

With the improvement of people's living standards, the transportation of drinking water by aluminum pipes and white iron pipes is no longer ideal. It is hoped to use stainless steel pipes or copper pipes for transportation, because the water quality is guaranteed, and the decoration of copper pipes and stainless steel is more luxurious and rich. However, the price of copper is high. In order to be practical and ensure that the cost is not too high, a kind of water pipe with thin stainless steel tube and thin copper tube came into being.

Abstract

The present invention relates to a pipe joint for connecting pipes, its two ends are equipped with external screw thread respectively, and it is characterized by that at least one end of the pipe joint also possesses a section of plug-in pipe outside having external screw thread portion, and the pipe mouth of the said plug-in pipe is equipped with a series of compressible notches. The invented advantages are that it not only can save labour for connecting pipes, but also its combination is tight fit, so that it possesses good leakage-resisting effect.

Description

technical field [0001] The invention relates to the connection of pipes, in particular to a pipe joint for connection of thin-walled pipes. Background technique [0002] Fluid conveying pipes, such as water pipes, generally have relatively thick walls in the water pipes currently available in the market, so the pipe walls can be directly threaded for connection. With the improvement of people's living standards, the transportation of drinking water by aluminum pipes and white iron pipes is no longer ideal. It is hoped to use stainless steel pipes or copper pipes for transportation, because the water quality is guaranteed, and the decoration of copper pipes and stainless steel is more luxurious and rich. However, the price of copper is high. In order to ensure that the cost is not too high for practicality, a kind of water pipe with thin stainless steel tube and thin copper tube came into being. There is also a variety of thin-walled tubes such as copper tubes wrapped in pla...
