21/5/2014· After installation of the re-round clamp, check roundness of pipe against measuring pipe diameter. If pipe is still oval, re-position the rerouding clamp (Fig. 7 and 8). 4. Scraping The Pipe Surface In order to remove the oxide layer of the pipe, scrape carefully the
Electrofusion is a simple, cost-effective method for joining HDPE pipe. As an alternative to butt fusion, electrofusion is ideal for repairs and difficult connections of HDPE pipe. It has been successfully and cost effectively used for appliions such as pipe bursting, slip lining, dual containment, directional drilling, and manhole connections.
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.
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
It is well known that it is necessary to scrape off a 0.2 mm outer layer of the PE pipe surface at the loion for the electrofusion weld prior to welding. The reason for this procedure is said to be removal of an oxidized layer (caused by UV degradation and/or the extrusion process) which can restrict molecular diffusion across the welding interface.
So, Hdpe pipe will be connected with the electrofusion fitting. Pe 100 pipes can be welded by Electrofusion welding method with Hdpe pipes of 20 mm diameter and up to 1200 mm diameter. The electrofusion welding method is carried out in accordance with DVS 2207 standard.
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.
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
