CenFuse/CenGas HDPE Socket Fusion Time Cycles CenFuse HDPE Pipe & Fittings 1. For this work, two factors are quantified. Butt Welding Testing Weld testing techniques can be divided into 2 categories – long term tests that are used to evaluate weld parameters and materials and short term tests that are used to assess production welds. Determine pressures (joining, heating, and fusion) for pipe size(s) per McElroy Chart. The debeading technique used should not gouge or otherwise damage the pipe. Attach the proper size heater plates to the heating tool. 8. In the field of welding, no matter what the material, cleanliness matters and should be emphasised throughout the process. Cut the pipe squarely with pipe cutter. Aug 12, 2024 · In this comprehensive guide, we delve into the essential techniques and timings involved in HDPE pipe fusion, a critical process in plastic welding. May 20, 2024 · Butt fusion is a thermofusion process . poor fusion etc. ambient temperature, the diameter of the pipe, and the wall thickness of the pipe. 29 Make joint Lubricate the pipe end and insert the pipe up to the marked insertion depth. Golf course irrigation Leak-free HDPE pipe exclusively for golf course irrigation. HDPE IRON PIPE SIZE (IPS) PRESSURE PIPE PE4710 DR 7 (333 psi) DR 7. Butt fusion is a process by which the square cut ends of two pipes or fittings of the same diameter, wall thickness and material type (PE80 or PE100), are fused together. In particular, the wall thickness and the ambient temperature. In butt-fusion, the strength of the joint is stronger than the pipe itself & the welding is homogenous. Parameter for welds with test channel. Illustration 8. 3 (318 psi) DR 9 (250 psi) DR 9. It describes the butt welding process, which involves trimming the pipe ends, heating them to melting temperature, pressing them together under pressure, and leaving them to cool under low pressure. 5 Snap joint Illustration 8.
