Tips about Hydraulic Butt Fusion Welding Machines

HDPE pipes have excellent performance, including good flexibility, corrosion resistance, and wear resistance, making them highly recommended. They are widely used in various fields such as gas transportation, water transportation, oil and gas gathering and transportation, municipal engineering water supply systems, building indoor and outdoor water supply systems, residential areas, plant buried water supply systems, old pipeline repairs, water treatment engineering pipeline systems, industrial water pipes in gardens, irrigation, and more. Therefore, the use of hydraulic butt fusion welding machines is also widespread.

However, it is important to note that polyethylene pipes have a temperature limitation. Generally, they can be safely used at temperatures up to 60 °C (140 °F). For projects involving higher temperatures, alternative materials have been required in the past. Fortunately, a bimodal high-density polyethylene (HDPE) resin with a rated pressure of 82 °C (180 °F) has been developed for demanding piping applications.

When it comes to making hot melt connections, it is crucial for butt welding machine suppliers to provide comprehensive skills and quality training to pipeline designers and constructors. This training will help them understand the HDPE pipe welding parameters, improving construction efficiency, avoiding rework, and ensuring safety during the use of hydraulic HDPE pipe welding machines.

The HDPE pipe welding temperature should be carefully controlled, not too high or too long. It is recommended to maintain the temperature at 210 ±10 ºC to prevent excessive melt extrusion and reduce the inner diameter of the water. Additionally, when working in open-air or sun-exposed areas, it is advisable to provide proper shelter.
