Several methods of PE pipe hot melt butt（2）

06 Dec 2019

⑶ Selection and quality control of hot-melt connection method The selection of the hot-melt connection method mainly depends on the material grade and density of the plastic pipe. The connection method of plastic pipes should also be based on the buried "Polyethylene Water Supply Pipe Engineering Technical Regulations" (GJJ101-2004) and other relevant regulations. Most polyethylene pipes can be joined together by two hot-melt methods. However, some high-density polyethylene pipes cannot be connected by the method of undertaking. When used in buried heat exchangers, polybutene is generally a socket connection. Both connection methods can be used to obtain a strong joint. Both connection methods are used properly to obtain strong joints, which are stronger than the strength of the pipe itself. It should be noted that due to different melting points and service life, different plastics or different grades of plastic should not be welded together. During construction, visual inspection and...

Several methods of PE pipe hot melt butt

29 Nov 2019

The connection joints of all polyethylene pipes must be connected by electric fusion or thermal fusion, but not by mechanical connection methods. The joints of thermal fusion connection are stronger than the pipeline itself. The joints or connectors are made of plastic and there is no corrosion problem. The choice of pipe connection method depends on the requirements and recommendations of the pipe manufacturer, and the skills of the site construction staff. Hot-melt connections are first trimmed, cleaned, aligned, and then heated to their melting points and joined together. There are two types of hot-melt technology in the industry: hot-melt and socket connection. ⑴Hot melt butt Hot-melt butt jointing is a method in which the end interfaces of polyethylene pipes are heated and fused with a heating plate to fuse with each other, and are fixedly connected together after cooling. Usually, a hot-melt electric welding machine is used to heat the end pipe, make it melt, quickly attach it, m...

Advantages of fully automatic hot melt welding machine

23 Nov 2019

Fully automatic hot melt welding machines are now suitable for welding in a variety of materials and industries. Welding of stainless steel, gold, silver, alloy, steel, pe pipe, etc., or, in use, we can see mobile phone batteries, sensors, medical devices, craft gifts, watches, electronic components, sensors, precision machinery, communications, etc. The industry will use this type of Hydraulic welding machines Automatic hot-melt welding machine can realize spot welding, butt welding, stack welding, sealing welding and so on. It offers the possibility of welding thin-walled materials and precision parts. The deformation is small and the welding speed is fast. The user-friendly design of the automatic hot-melt welding machine, liquid crystal display and button-operated operation make it easier for the operator to complete the work. The automatic hot-melt welding machine workbench adopts a rotatable system, which can not only realize spot welding, but also complete automatic welding such...

Welding characteristics of electric welding machine

15 Nov 2019

In terms of skills, the electric welding machine belongs to the power supply range. It integrates power electronics skills, active control skills, active detection and active identification skills, computer hardware skills, software skills, display skills, barcode scanning skills and database skills. Integral, the first is to supply constant welding voltage or welding current, and to test and control the welding process, so that the welding results reach the best form. Features: 1. Automatic IC closed-loop design, when the welding can not meet the welding conditions (such as voltage, current, temperature failure) according to the standard, it can automatically detect and judge a variety of welding faults, and prompt the corresponding alarm code for the operator's reference . 2. Connect the professional printer to instantly print out the actual parameters of the welding for archival purposes, providing a reliable guarantee for mastering the first-hand welding of real materials, copying ...

Automatic electrofusion welding machine selection and use skills

09 Nov 2019

Pe pipe automatic electric welding machine to improve the work attitude and continuous improvement of innovative ideas, won the recognition. Do we need to pay attention when using the electric welding machine? I believe that everyone has their own opinions on how to use the electric welding machine. Xiaobian will share with you some common problems about using electric welding machines: Each manufacturer's product model and parameters are different. Therefore, the latest electric heating and fusion welding machine should use the latest automatic electric heating and welding machine that supports manual and barcode use. Otherwise, the range of other products will be reduced during use. Thereby reducing the use efficiency, resulting in unnecessary waste, the price of the pe tube electric welding machine, will also have an impact on the quality of work. During construction, generally when the power supply is within 50 meters from the welder, it is necessary to select 2.5mm2 input cable, e...

How to use the hot melt butt welder

01 Nov 2019

Use of hot melt butt welder: 1, welding preparation The preparation for welding is mainly to check whether the condition of the welding machine meets the working requirements. For example, check whether the fasteners in various parts of the machine are detached or loose; check whether the electrical connection of the whole machine is correct and reliable; check whether the hydraulic oil in the hydraulic tank is sufficient; confirm that the power supply matches the requirements of the tool input; whether the heating plate meets the requirements (Whether the coating is damaged); trial operation of milling cutters and oil pump switches, etc. Then put the kava with the same pipe specifications into the rack; set the heating plate temperature to the welding temperature (the welding temperature of the polyethylene pipe channel is 200~230 °C), and wipe the heating plate with soft paper or cloth alcohol before heating. Surface, but be careful not to scratch the PTFE release layer. 2, welding W...
