We also provide HDPE pipe welding services. Both butt welding and electrofusion welding can be executed with automatic machines as per required standards. The HDPE pipe welding is basically of two types: 1) Butt Welding Butt Fusion Welding involves Puhui Pipe manufacturer in China
Electrofusion Fittings Electrofusion jointing is a method of welding polyethylene pipework. Joints are permanent, non-reversible and when done correctly are at least as strong as the pipework it joins. These come standard as 39.5V to suit most welding equipment in
15/5/2015· One of the methods of joining two HDPE pipe lengths together is through heat fusion. The above Automatic Hydraulic Butt Fusion Welding Machine shows the process of HDPE welding though Heat fusion metPuhui Pipe manufacturer in China
Meaning of Electrofusion Electrofusion is a simple method of joining PE pipes in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. Prefabried fittings are used, incorporating an electricalPuhui Pipe manufacturer in China
ELECTROFUSION SOCKET JOINTING 3. Mark the insertion depth on the pipe by holding the bagged fitting against the pipe. 5. Scrape one pipe end using a prescribed tool, for the length of the insertion depth plus 10-20mm. Ensure the whole surface area has 7.
INSTALLATION PROCEDURE The pipe ends must have a square, even cut (Remove reverted ends if necessary) Remove any burrs or shavings from the pipe ends (chamfering leading edge to ease insertion). Ensure clean hands with Pipe wipes or wear disposable gloves.

Plain pipes are jointed by means of electrofusion (EF) fitting incorporating an electrical heating coil which when electrically activated for the appropriate time by electrofusion welding machine, melts the surface of the pipe & fitting together resulting in complete fusion Puhui Pipe manufacturer in China
Acu-Tech sells a large range of equipment for HDPE welding and associated tasks. Pipeline installation requires a lot of tooling and machinery to complete the job. Firstly the poly welding equipment – either electrofusion welders or butt welders, as well as a host of supporting poly equipment – pipe scrapers, machines, generators, bead removers, extrusion guns, squeeze-off tools and pipe Puhui Pipe manufacturer in China
The Method of HDPE Fusion Welding Generally 1inch hdpe pipesing, HDPE pipe is butt fused by applying heat to prepared pipe ends and then pushing the pipe ends together with a pre-determined force to make a permanent butt fusion joint.

24th World Gas Conference WGC , ARGENTINA 2009 6 Figure 10.EF Welding Machine 4.1.1. FITTINGS USED IN ELECTROFUSION WELDING METHOD Sleeve Coupling: The fitting that is used to connect two PE pipes with the same diameter Reduction
Before scraping the pipe, measure the insertion depth of the fitting. With the fittings still in the bag, place alongside the pipe end and put a witness mark on the pipe at half the fitting length plus about 2cm to enable visual checking of the scraped area after jointing.
HDPE Fusion Procedures August, 2010 3 Roth Avoid pipe that is not black in color and pipe that does not have “C” as the UV stabilization digit in the cell classifiion. Along with the correct ground loop piping, fittings must meet requirements for O.D. controlled
ELEKTRA 315 is an universal electrofusion machine, suitable for welding pipe/fittings for the transport of gas, water and for welding fire sprinkler system (HDPE, PP, PP-R couplings from 8 to 48 V). The Elektra 315t machine is made in compliance with international standards.
