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 applications 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 requiring higher temperatures, alternative materials have been traditionally used. Fortunately, a bimodal high-density polyethylene (HDPE) resin with a rated pressure of 82 °C (180 °F) has recently 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 enable them to 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 to avoid issues. It should not be too high or too long, and the recommended temperature range is 210 ±10 ºC. Excessive melt extrusion can lead to a reduction in the inner diameter of the water. Additionally, it is advisable to provide proper shelter when working in the open air or under direct sunlight.
