Advantages Of HDPE Electrofusion fittings
As a unique memeber of HDPE fittings, electrofusion fittings has all advantages that HDPE fittings have, such as: hygiene, reliability, long-lifetime design, corrosion resistance.,etc.
 
By comparison of the other HDPE fittings, HDPE electrofusion fittings repute more benefits:
* A simpler installation process:electrofusion process is much simpler, and electrofusion machine is much smaller size & lighter weight, this allow the electrofusion fittings can be easily joined to HDPE pipes in circumstances where butt fusion is not practicable.
* lower installation costs & labor costs: electrofusion process is much simpler, and easily operation. This greatly reduce the installation costs & laber costs.
* More reliable joints: The consistency of the electrofusion welding process in creating stronger joints, which is more reliable. Due to more reliable joints, HDPE electrofusion fittings are very popular used in building & repairing gas distribution pipeline.
* Easy for repairing: HDPE electrofusion fittings support secondary welding when some joints leak, and HDPE electrofusion repair saddle can also easily repair the leaking of pipeline.

FAQS
* What's the electrofusion welding process?
A: Electrofusion welding involves the following steps:
• Preparing the pipe for removing the gaps and cleaning the contaminants
• Marking the connection on the pipe, rubbing the pipe surface
• Reinforcing and applying strain on pipe or connector
• Applied electrical current
• Cooling, opening clips
• Documentation of the process
• Final payment, cleaning and removal of contaminants
 
* HDPE butt fusion fittings & HDPE electrofusion fittings, which one is better?
A: HDPE butt fusion fittings & HDPE electrofusion fittings, both are the most common used HDPE pipe fittings.
 
* Material Costs
The HDPE butt fusion fittings are regular much cheaper prices than HDPE electrofusion fittings. The HDPE pipes adopt butt fusion methods, no special coupler fittings needed , so less fittings will be requested, and much lower on material costs.
 
* Installation Costs
The HDPE electrofusion fittings can be welded in much simpler way, which can be used for the certain circumstances where butt fusion is not practicable. Less installation costs & labor costs for electrofusion, as well as electrofusion machine is much lower on prices.
 
*Reliability of Jointing
HDPE electrofusion fittings has a more reliable jointing than HDPE butt fusion fittings. The HDPE electrofusion fittings can weld in secondary times when a leak happens.
 
So, it is difficult to distinguish which one is better, because both of them reputes excellent performances. The HDPE electrofusion fittings can save installation costs and provider a more reliable jointing while HDPE butt fusion fittings are much lower on material costs.
 
Finally, it depends on the project size and type, and location of installation.  Electrofusion fittings can be a better choice for smaller, tighter spaces where onsite welding is being used.
 
* Can HDPE electrofusion coupler be used for welding the PPR pipe?
A: No, HDPE electrofusion coupler is manufactured & designed to weld to the HDPE pipeline only, NOT suitable for PPR pipe.
 
* Is there any barcode on the electrofusion fittings provided by SUNPLAST?
A: Yes, all HDPE electrofusion fittings are with a barcode on it. The worker on site can use electrofusion machine to scan the barcode, so all welding parameter will be inputting to welding machine automatically.
 
* Can electrofusion fittings made by PE100 material weld to the pipe in PE80?
A: Yes, this will be ok. To guarantee the best welding result, we recommend to use PE80 fittings to weld to the PE80 pipe.
 
* What's the typical reasons that make the electrofusion welding fail?
A: The majority of fittings that leak do so because of incorrect installation. The three main causes of joint failure when using electrofusion fittings are:
• Poor joint preparation
• Contamination of the joint caused during the jointing process
• Misalignment of the pipe within the fitting.
 
So, to achieve the success of electrofusion welding, a well trained installer strictly follow the guide is very important.
 
* Is scraping necessary before Electrofusion?
A: Yes, before electrofusion, the installer shall scrap the oxidation layer on both edage of HDPE pipe, the scrap area shall cover the edage of pipe to the marking line on the pipe, which mark insert depth of the electrofusion fittings. This is necessary step.
 
* What's the effectiveness of electrofusion welding?
A: The effectiveness of electrofusion depends on attention to preparation of the jointing surfaces and ensuring that the surfaces to be welded have satisfactory contact during the welding and cooling cycles. The pipe surfaces to be fused need to be scraped to remove the surface oxidation layer prior to fusion.
 
To prepare the jointing surfaces the pipe surface must be scraped with an appropriate pipe scraper, as recommended by the pipe or fitting manufacturer, to remove the entire surface of the pipe over the area indicated, to a depth of approximately 0.3mm. Following scraping the scraped surface must be wiped with an authorised Ispropanol impregnated pipewipe, as recommended by the pipe or fitting manufacturer, to remove any dust residue. Methylated spirits, acetone, methyl ethyl ketone (MEK) or other solvents are not recommended for wiping the scraped surface. The prepared surfaces must be completely dry before proceeding.
 
The resulting joint, when properly made, is as strong as the original pipe and can withstand all the loads applied during routine installation and operation.
