Product Description

 
Electrofusion welding is the most common welding technique for joining HDPE pipes. Electrofusion fittings with implanted metal coils is placed around two ends of pipes to be joined, and current is passed through the coils. Resistive heating of the coils melts small amounts of the pipe and fitting, and upon solidification, a joint is formed.
 
SUNPLAST HDPE electrofusion fittings provide simple method of joining HDPE pipes in circumstances where butt fusion is not practicable, and they are commonly used for the construction and repair of water plumbing & gas distribution pipeline.
 
About HDPE electrofusion Coupler
HDPE electrofusion coupler, also called HDPE electrofusion coupling, is the most common & regular fittings that are used to join two lengths of poly pipe in a straight line, and it can also be used to join a long spigot fittings to a piece of pipe.
 
Made by 100% PE100 material, SUNPLAST HDPE electrofusion coupler can come with a size range from dn20~dn630mm. The diameter dn25mm to dn315mm can be in SDR11-PN16 bars, while the diameter dn355 to dn630mm in both SDR17-PN10 & SDR11-PN16.
 
The electrofusion coupling fittings are injection molded in one time, and conform to ISO4427-3,EN12201-3, AS/NZS 4129, EN1555, EN ISO15494 standard.
 
SUNPLAST keeps mass stock in demand for regular sizes, and customers' urgent demand & prompt shipment request can be satisfied.

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
* Which SDR of HDPE fittings shall we use for the HDPE pipe in SDR13.6-PN12.5? Can we use the SDR17 fittings for our SDR13.6 pipe?
A: To guarantee the safety of piping system, the HDPE fittings shall be equal to or higher pressure rating than pipeline. So for HDPE pipe in SDR13.6, you shall take the fittings in SDR13.6 or SDR11. The fittings in SDR17 is not suitable for SDR13.6 pipeline.

* What kind of HDPE pipe fittings can SUNPLAST provide?
A: SUNPLAST is a integrated manufacturer & provider of HDPE fittings in China. We currently can provide three kind of fittings:
HDPE butt fusion fittings: available in a diameter ranging from 50mm to 800mm in SDR17 & SDR11
HDPE electrofusion fittings: available in sizes of 20mm to 630mm in SDR11 & SDR17
HDPE compression fittings: for small diameter 20mm to 110mm in PN16

* Can SUNPLAST provide HDPE fittings in PE80 material?
A: Yes, PE80 fittings are also possible to us.

* Can HDPE fittings made by PE100 material weld with pipes in PE80?
A: yes, they can be welded together. But, to achieve the best welding results, we recommend to weld PE80 pipes with PE80 fittings.

* Is HDPE end cap & HDPE pipe end the same thing?
A: yes, they are referring to the same products.

* Can HDPE fittings connect to PVC pipe? Or can HDPE fittings connect to PPR pipe?
A: For thermal plastic fittings, they can be connect to the pipes with same material grade only. So, for HDPE fittings, they can be connected to HDPE pipe only, but can't connect to PVC pipe or PPR pipe.

* How can we connect HDPE pipes to PVC pipes?
A: Since HDPE pipe & PVC pipe are made of different material grade, they are unable to connect together by "heat-fusion".

The possible way to connect them together is by flanged connection. To use HDPE flange adaptor & HDPE backup flanges to make it possible to connect to PVC flanges.

* Is SUNPLAST HDPE fittings UV resistant?
A: Yes, HDPE fittings are UV resistant and UV stable and will not structurally degrade from UV light. After a lengthy period of direct UV light contact, the external surface of the fittings change visually to a slightly waxy look, but this does not affect the performance and is removed by a rotary pipe scraper prior to electrofusion welding.

* What's the warranty can SUNPLAST provide?
A: All our HDPE fittings are made of virgin PE100 material, and are designed for 50 years lifetime. SUNPLAST will provide a warranty time in quality of 10 years for regular use.
