What are the steps of electrofusion connection of steel wire mesh skeleton composite pipe

Tsinghua Pipe Industry, with a registered capital of 60 million yuan, is a modern high-tech industry specializing in the research, production, sales and installation services of steel mesh skeleton plastic (polyethylene) composite pipes. The company's leading product, steel wire mesh skeleton plastic (polyethylene) composite pipe, with its unique anti-corrosion, wear-resistant, high-temperature resistance, cold resistance, pressure resistance, creep resistance, good stability, easy installation and other characteristics, gradually replaces all kinds of metal pipes and plastic pipes, and is widely used in petroleum, chemical, gas, water supply, mining, seawater transportation and other fields.

First, the electric fusion pipe fittings are sleeved on the pipe, and then the electric fusion pipe fittings are energized with a special welding machine according to the specified parameters (time, voltage, etc.), so that the inner surface of the electric fusion pipe fittings embedded in the electric heating wire and the outer surface of the pipe insertion end are melted.

How are the electrofusion pipe fittings installed, the pipe and the pipe fitting are fused together after cooling.

How to connect electrofusion pipe fittings --- procedures for electrofusion socket connections:

1. Pipe cutting: The connecting end of the pipe is required to be cut vertically to ensure that there is enough hot melt area. Commonly used cutting tools include rotary cutters, saw bows, plastic pipe scissors, etc.; High temperature is not allowed to be generated during cutting, so as not to cause high temperature deformation.

2. Clean the joint and mark the insertion depth line: scrape off the oxide layer on the surface of the pipe with fine sandpaper, scraper, etc.

For the manufacturer of electrofusion pipe fittings, wipe the dirt on the connecting surface of the pipe and pipe fittings with a clean cotton cloth, and mark the insertion depth line.

3. Pipe fittings into the pipe: Insert the electrofusion pipe fittings into the pipe to the specified depth, and connect the welding machine with the pipe fittings.

4. Correction: adjust the position of pipes and fittings so that the pipes and fittings are on the same axis.

Electrofusion pipe fittings to prevent eccentricity from causing the joint welding to be not firm and the air tightness is not good.

5. Energized welding: The time and voltage of energized heating should comply with the regulations of the electrofusion welding machine and the electric fusion pipe fitting manufacturer, so as to ensure that the best fusion joint is obtained under the best supply voltage and the best heating time.

6. Cooling: Since the PE pipe joint can only reach its maximum compressive strength after it is cooled to room temperature, other external forces during the cooling period will make the pipe and pipe fittings unable to maintain the same axis, thus affecting the quality of the welding, therefore, the connected parts shall not be moved or external force shall be applied at the connection during the cooling period.

Summary. Hello dear, happy to answer your <>

The hot melt method of PE steel wire mesh skeleton pipe composite pipe mainly includes the following steps:1Preparation:

The PE pipe and steel wire mesh skeleton pipe are pretreated according to the requirements to ensure that the surface of the pipe is clean and free of oil, impurities and moisture. 2.Hot melt connection:

The pretreated PE pipe and the steel wire mesh skeleton pipe are inserted into each other according to the required length and hot-melt welded using an electric hot melt welding machine. 3.Check the connection quality:

After the hot melt welding is completed, use the feel or tool to compact the pipe connection to check whether it is firm and free of leakage. 4.Free cooling:

Let the welded pipes cool naturally, and do not move or forcibly change their connection status too soon to prevent cracks or water leaks.

If there is a little dripping water in the pipe, can it be connected?

The pretreated PE pipe and steel wire mesh skeleton pipe are inserted into each other according to the required length, and the hot melt welding is carried out using the telecom wood hot melt welding machine. 3.Check the connection quality:

After the hot melt welding is completed, use the feel or tool to compact the pipe connection part to check whether the shed silver is firm and there is no leakage. 4.Free cooling:

Let the welded pipes cool naturally, and do not slip prematurely and change their connection state by moving or forcibly to prevent cracks or water leakage.

When the hot melt welding of the PE steel wire mesh to the composite pipe of the ant skeleton pipe is buried, there can be no water or other liquids inside the pipe, otherwise the effect of hot melt welding will be affected. Because at high temperatures, water or other liquids will quickly become resistant to vapor, forming a large air pressure, resulting in distortion and deformation of the pipeline, and even serious accidents, so it is strictly forbidden to have a little drop of water inside the pipeline.

Is there still a little water in the pipe?

Kiss, no.
