Prepare the pipe surface with above Manual scraping Procedure for Socket Fitting. Ensure inner side of fitting clean and dry. Follow the same procedure for fusion jointing of coupler. Join the metal part of other end with threaded pipe as per standard
Jointing procedure 1. Cut the pipe square The pipe ends must be cut square to ensure that the heating element in the coupler is completely covered by the pipe or fitting. 2. Mark insertion depth + 10 mm This is to ensure that across the full welding zone the
The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A''s) of all the elements through the pipe system value chain: design, materials, construction

Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself.
Both pipe clamps must be adjusted so that they hold the pipe tightly enough to withstand the force of the welding process. Press the pipe ends against hot plate by briefly applying a high pressure. Continue heating very low pressure until an up stand of 1 mm has formed.
Our work procedure provides for the necessity of scraping and cleaning the pipe surface before fusion jointing. In order to maintain high and uniform quality of EF jointing work, we have developed an electric scraper for saddle fusion and an ethanol-saturated bottlecontained wet wiper for cleaning.
This document outlines the procedures for joining polyethylene pipe & fittings by butt fusion. Materials that have been pre-qualified to be joined by this fusion procedure are within the nominal melt HDPE Pipe PN16 SDR11 range of 0.05 to 0.25 gm/10 minutes (190 C/ 2.16 Kg), or a
The overall toughness, flexibility and impact resistance make it an ideal pipe system for even the most demanding appliions. Akatherm HDPE offers a choice of welded and mechanical jointing techniques.

1/7/· , it is found that the biaxial stress ratio, which means a ratio of a hoop stress to an axial stress, is 2 for the HDPE pipe specimen for the sustained pressure test. However the total axial stress can be significantly higher than a half of the total hoop stress in the actual piping systems of nuclear power plants as presented in Eq.
Heat fusion can be used to join sections of HDPE pipe, including high-performing PE4710 pipe, while electrofusion is used to add couplings, tapping tees, branch saddles and other fittings. Proven to be a reliable joining system, an electrofusion joint is heated internally, either by a conductor at the interface of the joint or by a conductive polymer.
JOINTING: A wide range of UPVC Pipes & Fittings are available. They are economical, durable, leak proof, easy & quick for the connections. These Fittings include Coupling Sockets, Elbows, Tees, end Caps Flanges, (45 & 90) and reducers. UPVC Pipes & Fittings are available in various sizes for different pressure classes of Pipes.

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. It is a very simple process utilizing a properly sized butt fusion machine for the pipe size to be joined.
The most common welding method used today is the joining of Hdpe pipe and fittings by Butt Welding Method. The joining method is connect the ends of pipes to be welded by using butt welding machine and both ends are pushed toward each other by pressing
immediately place over pipe end and push up to centre stops, or for fittings without centre stops insert the pipe to half the overall fitting length (mark this distance on the pipe prior to insertion). Leave bag over fitting for temporary protection. SOCKETS JOINT 1.
pressure, exerted on the pipe or fittings ends during the cooling cycle of the dual low-pressure procedure after jointing time Note 1 to entry: The value of the corresponding gauge pressure is calculated with the formula given in 4.7 .
