The result of the task group work , along with input from utility users and industry expertise, is the following technical report, TR-49 - Generic Electrofusion User Guide HDPE Fittings - A Complete Guide:Provident ProcurementAccording to the PPI, the purpose of this guide is to provide important safety information on handling, lifting, storing and installing polyethylene pipe and fittings. By adhering to these and other safety guidelines, it is the sincere hope of the PPI and its members that the number of serious accidents and injuries [related to HDPE pipeline HDPE Fusion Procedures - roth-usaHDPE Fusion Procedures August, 2010 Roth 4 Overview Pipe fusion is necessarily performed outdoors in order to join the ground loop piping in the header trench. In many cases, trenches are damp or even wet. Fusion should never be attempted in a wet trench. HDPE can produce static electricity that could be dangerous in an explosive environment.

Mitigating Cold Weather Challenges in Butt Fusion IGSHPA

Dec 19, 2019 · Pipe Slippage Do watch for pipe slippage in the fusion machine. Polyethylene pipe becomes stiff in cold weather and the outer diameter can shrink, making it prone to slippage and causing a bad fusion. Tips for Coiled Pipe Coiled pipe is also uniquely effected in PVC-O and PE joint procedures molecorThe article below outlines the differences between making a push-fit connection on PVC-O pipes and Butt Fusion Welds required for PE pipes. PVC-O Pipe Joint Procedure The connection is made by introducing the male (spigot) part of the pipe into the socket where the elastic joint is placed.

Plastics Pipe Institute Energy Piping Systems Conduit Plastic pipe delivers exceptional value, unwavering reliability and remarkable advantages over conventional types of piping. It's today's right choice for water service, drainage, fuel gas, conduit and plumbing & heating. Other reasons plastic pipes are a superior choice:Long-term service life Poly welding methods for Blackpoly Poly pipe solutionsPLASTIC WELDING / POLY WELDING. Plastic Welding or Poly Welding for semi-finished plastic materials is described as a process of uniting softened surfaces of materials, generally with the aid of heat (except solvent welding). Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling.
