In recent years, Corrugated pipes have developed very rapidly. HDPE Corrugated pipes are increasingly favored in both domestic and industrial applications for their environmental safety and play an important and irreplaceable role. With its unique advantages, it is widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes. So, do you know which way to install the bellows is the most correct? The following article introduces the knowledge of the installation of Corrugated pipes, hoping to help you better understand them.


The main points are as follows:

※ What is Corrugated pipe

※ How to install Corrugated pipes

※ Precautions when using

※ In conclusion


What is Corrugated pipe

Bellows is a new type of light tube made of high density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long service life. Its excellent wall structure design is similar to other structures. By contrast, costs are much lower. And because the connection is convenient and reliable, it is widely used at home and abroad. Extensive replacement of concrete and cast iron pipes.


Bellows installation method

Corrugated pipes are available in several ways:


1. Electric heating ribbon connection

The electric heating ribbon is connected by a specially made electric heating ribbon. The inner surface of the electric heating ribbon of the polyethylene is embedded with a heating wire. After the electric current is applied, the electric melting shaft extrudes the molten material to form a pressure, and the polyethylene on both sides of the interface diffuses with each other, and the power is turned off, and a sufficient connection is formed after being sufficiently cooled and solidified.


2. Heat shrink sleeve (with) connection

The heat shrinkable sleeve (belt) is made of a polyethylene sleeve (belt) and a reinforcing fiber web. After the electron accelerator is irradiated, the polyethylene is crosslinked, heated, expanded and cooled, and the inner wall is coated with a hot melt adhesive. When the joint is applied, it is placed at the joint of the pipe section to be connected, and the heat shrinkable sleeve (belt) is shrunk and the inner wall hot melt adhesive is welded by the torch to form a joint which does not leak and has a certain strength.


3. Clamp and sealing tape connection

The connection of the clamp and the sealing tape is to entangle the two pipe segments to be joined from the outer circumference by a metal clamp which is divided into two parts, that is, consisting of two pieces of half-divided, and the large diameter can be composed of four pieces. The clamp is provided with a raised or curved edge to catch adjacent ribs, so that the two pipe segments to be connected are also fixed in the axial direction. A layer of elastic sealing band is added between the clamp and the pipe, and an elastic sealing block is plugged on both ends of the broken joint of the spiral groove of the steel belt reinforced polyethylene spiral corrugated pipe, and the elastic sealing band is pressed by the lock force of the clamp And the elastic sealing block to achieve the sealing and non-leakage requirements of the connection.


4. Extrusion welding

Extrusion melt welding is to use a hand-held welding torch to extrude molten polyethylene material and weld the polyethylene on both sides of the joint. The hand-held torch body is a small-diameter extruder that can deliver the polyethylene electrode. Extrusion after melting. At the same time, the polyethylene part to be welded is preheated with hot air.


Precautions when using

Because Corrugated pipe is bulky, we need to pay attention to some aspects when installing the connection.


1. HDPE Corrugated pipes cannot be connected with pipe fittings with a soluble binder.


2. Before the interface, check whether the rubber ring is in good condition, and confirm the position of the rubber ring and the insertion depth of the socket.


3. When the interface is installed, first clean the inner wall of the socket, and apply lubricant to the inner wall of the socket and the rubber ring of the socket, and then align the central axis of the end surface of the socket.


In conclusion

With the development of the times, the progress of society, more and more high-tech has been paid attention to by people, so HDPE Corrugated pipe has become more mature in its production process and use technology. Moreover, due to the excellent performance and relatively economic cost of the product, its products can be recognized by consumers in the developed countries such as Europe and the United States and the country's strong support. In recent years, this HDPE corrugated pipe has been introduced to China, and has received strong support from China. Therefore, the sales of this new lightweight pipe in the market is amazing, and it has replaced the position of old-fashioned pipe in the market, such as your current needs. If you are interested in HDPE Corrugated pipes, please contact us and we will be happy to help you. And we can also provide the karh pipe, tank winding machine,etc.
