HDPE Buttfusion Welding Machine

HDPE Buttfusion Welding Machine is a device specially used for hot-melt butt welding of high-density polyethylene (HDPE) plastic pipes. It is suitable for hot-melt butt welding of 63-160 (mm) PE, HDPE, PP, and other plastic pipes, and is composed of an operating platform (hydraulic, electronic), a fixture rack, a heating plate, a milling machine, and other parts.

The most popular and reliable welding method for HDPE pipe is Butt fusion welding. Butt fusion welding is thermal jointing. The principle is to heat two pipe ends to a designated temperature, and then fuse them together by application of sufficient force. The quality of joints then depends on the quality butt welding machine, proper welding parameters, and the experience of the welder.
Whatever the project, whatever the need, JUNRUI has the HDPE fusion equipment and expertise to always deliver the right solution. As one of the industry leaders in this field for more than decades, we excel at solving problems and providing custom-made solutions for each valued customer.

HDPE Buttfusion Welding Machine Function

HDPE Buttfusion Welding Machine heats the end of the pipe to melt it, and then quickly cools it to achieve a firm connection between the pipes. The use of this equipment makes the connection of PE pipes more reliable, able to withstand higher pressure and temperature, and suitable for various occasions requiring high-pressure fluid transmission. The machine is suitable for pipes with a diameter of less than or equal to 160mm. For pipes with a diameter greater than 160mm, the electric fusion welding method is applicable, and the HDPE ElectroFusion Welding Machine is used for operation.

Operation process

1. Clean the interface ends of pipes and fittings.

2. Plane the connection surface of the pipe and fittings, check the connection surface of the pipe end, and ensure that the gap does not exceed 0.3mm.

3. The pipes and fittings should be on the same axis, and the misalignment should not be greater than 10% of the wall thickness.

4. Place the heating tool between the two connection surfaces. Let the pipe on the Buttfusion Welding Machine approach the heating tool and apply a certain pressure until it melts to form a smooth and symmetrical flange along the entire outer circumference of the pipe.

5. After heating, the connecting piece should be quickly separated from the butt connection heating tool, and use uniform external force to make it fully contact to form a uniform flange, and the flange hardness reaches a certain degree.

Product Features

1. Wide range of applications: Suitable for connecting HDPE pipes of different specifications and sizes, including but not limited to pipeline systems in the fields of water supply, drainage, and natural gas transmission. ‌

2. High connection quality: Through precise temperature control and a uniform heating process, the sealing and durability of the connection are ensured. ‌

3. Easy operation: The HDPE Buttfusion Welding Machine is designed with ease of operation in mind so that even beginners can get started quickly. ‌

4. Strong corrosion resistance: Due to the corrosion resistance of HDPE materials, this welding method is particularly suitable for environments that need to resist chemical corrosion.‌‌
