How to understand PVC joints?

Views:0     Author:Site Editor     Publish Time: 2019-12-13      Origin:Site

With the development of social economy, various industries have been greatly developed. At this time, PVC pipes with portable, durable and other functions, have been more and more widely used. I don't know if you know that all kinds of pipes we use now in our homes and yards must be connected to pvc pipe coupling. Because only in this way can they play their greatest role. So, what exactly is the pvc joint? What kinds and advantages does it have? Next, we give a brief introduction to this, hoping to help you better understand the PVC pipe and pvc pipe coupling.


The main points are as follows:

♦ What is a pvc pipe coupling

♦ Type of pvc pipe coupling

♦ Advantages of pvc joints

♦ Conclusion


What is a pvc pipe coupling

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 of the pipeline is polyvinyl chloride, and the bottom layer is the back coating 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 joints, we can provide different materials and specifications according to your needs.


Type of pvc pipe coupling

At present, PVC pipe is a kind of pipe used for decoration. When using PVC pipe for decoration, due to the reasons of house structure, it is necessary to use some pvc joints with different structures to change the direction of the pipe for easy construction. Let's show you about these different pvc joints.


(1) Shun Shui San Tong

Shunshui tee is a kind of pipe fittings in drainage pipeline, which is used for vertical connection of branch pipe and main pipe. Although it is a vertical connection, the connection between the branch and the main pipe is not a vertical cross, but a small part of the arc connected along the direction of water flow, which makes the branch water very smooth.

It flows to the main pipe. The commonly used three-way downstream PVC, small radian, is to play the role of downstream.


(2) Think along the river

Four connections are pipe fittings and pipe connectors. Also known as quadruple joint or quadruple joint, quadruple joint for main branch. PVC four-way nozzle has the same diameter and different diameter, and the same size as the four-way nozzle with the same diameter; the four-way nozzle with different diameter has the same size, while the nozzle size of branch pipe is smaller than that of main nozzle. Four-way is a kind of pipe fittings used in branch of pipeline.


(3) 45 degree elbow

45 degree elbows are fittings and fittings. For main and branch pipes. Change the direction of the pipe.

The 45 elbows commonly used in daily life are basically made of PVC, because they are of good quality and more convenient to use.

The connection modes of PVC 45 degree elbow and pipeline include direct welding (commonly used) flange connection, 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.


(4) 90 degree elbow

The 90 degree elbow made of PVC is a kind of pipe fittings commonly used for pipeline installation, which is used to connect pipeline bending and change pipeline direction. Usage: Connect two pipes of the same or different nominal diameters to make the pipes rotate at different degrees of 90 degrees.


Advantages of pvc joints

Compared with joints made of other materials, what are the advantages of pvc joints?


(1) The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipe is high.


(2) It has good anti-aging performance, and its normal service life can be more than 50 years.


(3) The pipeline has excellent corrosion resistance to inorganic acids, alkalis and salts, and is suitable for the discharge and transportation of industrial sewage.


(4) Pipeline friction coefficient is small, water flow is smooth, blockage is not easy, maintenance workload is small.


(5) The material with high oxygen index belongs to B2 flame retardant material and has self-extinguishing property.

(6) The coefficient of linear expansion of pipeline is 0.07 m/m.0c, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus of cast iron drainage pipe are small, and the frost resistance of cast iron drainage pipe is better than that of cast iron drainage pipe.


(7) Pipes and fittings can be joined by bonding. The construction method is simple, the operation is convenient and the installation efficiency is high.



Therefore, with the increasing application of PVC pipe fittings, more and more pvc joints have been invented and put into use. Moreover, compared with other materials, PVC pipe fittings have the outstanding characteristics of light weight, high compressive strength and corrosion resistance, which are welcomed by the engineering community. So, if you want to know more about pvc pipe coupling or want to buy our products, please feel free to contact us. We would be happy to answer your question.
