The main points are as follows:

♦ What is a PVC joint

♦ Type and function of PVC pipe coupling

♦ How to repair PVC pipe

What is a PVC joint

The main component of PVC pipe is PVC. Adding other components to enhance its heat resistance, toughness and ductility. The top layer of the surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is backcoat adhesive. PVC pipe joint is one of the simplest PVC joints. Such joints are usually permanently connected or "coupled" from one component to another. They can connect pipes to pipes, pipes to fittings, and even connectors. Some of them are even reduced, so you can connect a small tube to a large one, and vice versa. For PVC pipe coupling, we can provide sliding or internal thread ends according to your needs.

With the development of related industries, more and more kinds of PVC pipe coupling are available. Here we briefly introduce its types and related roles.


(1) 45 degrees elbow

They are pipe joints and pipe joints. Use the main pipe and branch pipe to change the direction of the pipe.

Generally speaking, the 45 degree elbow used in daily life is basically PVC material, because it is of good quality and easy to use.

PVC 45 degree elbow is connected with pipeline by direct welding (the most common way) flange, hot melt connection, electric melt connection, threaded connection and socket connection. According to the production process, it can be divided into welding elbow, punching elbow, pushing elbow, casting elbow, etc.


(2) 90 degree elbow

The 90 degree elbow of it is a common connecting pipe in pipe installation. It is used to connect elbows to change the direction of the pipe.

Other names: 90 degree elbow, right angle elbow, love elbow, punch elbow, press elbow, mechanical elbow, welding elbow, etc. Usage: Connect two pipes of the same or different nominal diameters, so that the pipes rotate 90 degrees to different degrees.


(3) Shun Shui San Tong

Water supply tee is a kind of pipeline in drainage pipeline, which is used for vertical connection between branch pipe and main pipe. Although it is a vertical connection, the connection between branches and managers is not a vertical cross, but through a small smooth flow connection, which makes branches flow horizontally and steadily to managers. The commonly used PVC water supply tee is a small arc, which plays the role of water.


How to repair PVC pipe

PVC pipe is indispensable in our daily life. PVC pipe has excellent characteristics and stability, and has been widely used in various fields. In our daily life, we encounter broken or perforated PVC joints. In this case, how should we remedy them?


(1) First of all, PVC bushing with the same diameter should be used, but enough length is needed to cover the defect. Then the sleeve should be cut longitudinally and clamped in the pipe from one end.


(2) Clean the adjacent area, then apply special adhesive, wipe the end of the pipeline from inside to outside.


(3) Wait until the adhesive is dry, tighten it by hand, and then conduct a water test to see if there is leakage.



In recent years, PVC joints are more and more widely used. It consists of polyvinyl chloride resin, stabilizer, lubricant and so on. Because of its light weight, corrosion resistance, high compressive strength, safety and convenience,PVC joints are welcomed by the engineering community. It has become a popular, popular and widely used synthetic material in the world. If you want to know about our products, please feel free to contact us and we will answer your questions.
