One of the most general challenges we notice in the field is ensuring successful fusion fittings. Installations may be intriguing, sometimes due to working in restricted spaces, busy sites and varying weather conditions. However, it doesn’t have to be. Maintaining a methodical approach in the installation and preparation of an electrofusion welder will make the procedure so easy every time. That’s why we always suggest trained and accredited personal conduct electrofusion welding to ensure the longevity and success of the weld. Some simple tips to ensure the procedure go conveniently: The oxidized layer of the pipe should be removed with a well-fitted, top quality scrapping equipment; otherwise the quality of the joint can be seriously compromised:

Welding techniques have been used for more than 4 decades, taking benefit of the attributes of thermoplastic PE, both for water and gas pipes. Two types of welding methods are mainly used: An electrofusion welder and a butt welder. Both methods are quite simple to perform in the country, but it is important that the surfaces should be prepared properly to be welded and that the welding parameters are strictly utilized. Both electro fusion fittings and butt welding machines are generally more automatic, though the skills of the workers and training are still quite vital. It is being introduced as the automatic welding machines that alleviate the welding procedure with all the vital parameters, with the aim of having the traceability of them. It is suggested not to join with butt welding pipes of various materials and with different wall density. In this situation, it is recommendable to weld the pipes with an electrofusion welder. The butt welding process can only be done to join pipes with the same wall density. According to me, we should choose the best system of joining according to the type of work we have to do as both systems have displayed their dependability every time they have been used under the defined conditions. Giving an oval shape to the PE pipes is more problematic for the electrofusion welding than for the butt welding, and that’s why huge manufacturers of electro fusion fittings put pressure on the standardization committees to lessen the resistance of ovality in PE pipes. Most of the issues I have faced during the introduction of the elctrofusion fittings for water pipes have been created by not scraping the pipes, as PE pipes are in contact with the oxygen of the air so they suffer a bit superficial rusting that should be eliminated by scraping. The electrofusion welding is just another traditional fusion system; nonetheless it presents a radical difference. It is distinguished by integrating an inner electric heating element connection. That means that the difference is the technique through the one the heat is implemented. While speaking about electrofusion, we can distinguish between two techniques, through overlap and fitting. Fusion fittings refer to pipe fusion through a specific fitting for this procedure. It is carried out by applying heat and joining the outer pipe edges during a specific period of time. While applying the electrical power, the inner fitting surface is melted with the pipe outer one through heat. As polyethylene fusion is one of the components, these become part of a single piece. The procedure comprise of the following phases: 1.Scrape by using a scraper from the polyethylene surface which will be joined to the assembly. It is vital that the scraped surfaces are not contaminated. 2.Clean the pipe surface where the joint is going to be carried out with electrofusion welder along with disposable absorbent paper and alignment at the ends. 3.Put the pipes, holding them in the hand press in order to prevent them from moving. It should be ensured that the assembly is centered on the edges of the pipe surface, and also it is vital not to touch the pipe with your hands as the areas can be polluted by oils and body sweating, affecting the welding performance. 4.Decide insertion depth of the pipe with respect to the fitting, for instance, pointing out the pipe at the same length. To get the best possible outcomes, it is suggested to place pressures closest possible to the assembly. 5.Connect the electro fusion fittings and elements to the control box from the assembly and to the battery. According to the detail and complexity you need, there are a couple of approaches to consider here. The best one would be to ignore the disagreements before and after the electrofusion welder works, but you can take it all the way and make your excess welding material that you can drop on every fitting you have. On my plant layouts, I always neglect them because we generally have plenty of space and disagreements can be ignored. A simple 10 meter pipe will integrate any variation from thermal expansion to welding. So unless you’re designing medical equipment or any such thing, I wouldn’t bother. Keep this as a reference if occasionally you have to do readings, or the client asks for these welds to be in position and neglect them the rest of the time. On the other hand, avoid grime if you require proper dimensions and BOM reports. Then you have to over-define the engagement dimensions so that the parts interfere and thereby reporting right route dimensions and pipe length, node to node. If you have to get all that precision and you have ample time, then I would recommend you to get the fusion fittings so that you can drop on every fitting. If you require fittings like tees, elbows, or anything else that has table and may go to a Content Center, then you should define the new planes driven by the fusion distance and then set your engagement to plane, so that you can drive the engagement for every fitting diameter separately. I suggest that you don’t change the pipe as you may use that pipe on different connection types such as jointed, welding, socket etc and it will mess things up. Carry out all the changes in the fittings and it will drive the pipe engagement also. Our company includes the production and sales of better quality thermoplastic polymer products. One of our core expertises are piping systems made of polyethylene (PE). Our product group provides a full top quality range of pipes, valves, Fusion Fittings and exceptional items. The major target is the environmentally friendly and secure supply with natural gas and drinkable water as well as the ejection of decay water. Furthermore, we ensure that our pipe and fitting equipments are always kept updated and fulfill the technical demands of the municipal natural gas and water supply. These are especially created for reliable, great performance pipe joining and long system life. This mechanized system has been verified to be most cost-effective due to the low potential for operator’s fault. Waste Water System: Polyethylene gives the efficient cost-effective and technically preferable substitute to other materials, compelling minimum difficulty to install, decreasing the sum of connections needed and raising the system lifespan. Our system establishes an admirable investment for both public wastewater frameworks and private wastewater systems. Electrofusion wastewater system provides an energetic, long-life and is repellent to basic capacity through its exclusive functional products that can be finally combined after being established. Heat Fusion: The principle behind heat fusion of Electrofusion Welder is to heat two surfaces to a nominated temperature, and then fuse them together by utilization of the appropriate force. This applied force fixes the melted areas appearing in an enduring, imposing fusion joint. Poly Pipe fusion methods needs definite tools and component for the fusion type and for the sizes of pipe and fittings to be fixed. Properly joined PE joints generally do not leak. If a crack is encountered during hydrostatic testing, then it can be an occurrence to a system failure. Our company includes the production and sales of better quality thermoplastic polymer products.
