Product Description

HDPE Flange Adapter, also called HDPE stub flange or HDPE stub end, is a cost effective, easy to assemble, mechanical joint intended to connect HDPE pipe to any flanged piping components (such as valves, pumps..etc) without the need for costly fusion equipment.
 
When joining to metal or to certain other piping materials, or if a HDPE pipe section capable of disassembly is required, HDPE flange adaptor or HDPE stub flange are available. These items are designed so that one end matches the HDPE pipe for a butt fusion connection, the opposite end contains a stub that provides structural support. By utilizing the addition of a steel backup ring, it permits bolting to a similar flanged end connection to another pipe, of various possible materials.
 
HDPE flange adaptor shall be assembled together with steel backup rings (G.I. backing rings). Steel bolts/nuts & rubber gaskets will be also requested.
 
SUNPLAST HDPE flange adaptor fittings can be supplied in diameters ranging from 50mm to 1200mm in SDR11 & SDR17. The Fittings in SDR 11 are rated to PN16 for water and PN10 for gas, while SDR 17 fittings are rated to PN10 for water and PN6 for gas.
 
SUNPLAST HDPE stub flanges are injection molded type, fabricated by 100% PE100 material, can fully 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.

HDPE Fittings SUNPLAST Can Offer
SUNPLAST is a professional manufacturer of HDPE fittings over 20 years in China, and here in SUNPLAST, all customers can find the best solution of fittings for their pipeline systems.

SUNPLAST HDPE butt fusion fittings can be supplied in a diameter ranging from dn50 to dn800mm in both SDR11 & SDR17, with regular types: HDPE end caps, HDPE reducer, HDPE 90 degree elbow, HDPE 45 degree elbow, HDPE 22.5 degree elbow, HDPE equal tee, HDPE reducing tee, HDPE flange adaptor, G.I. backing rings.,etc



Advantages Of HDPE fittings
The reason why HDPE pipe has become the most common solution for water plumbing, a reliable HDPE fittings play a important role, as there are many advantages as below:
* The HDPE fittings, including HDPE butt fusion fittings & HDPE electrofusion fittings, are thermal plastic fittings. The pipeline & fittings can be welded together in a heat-fusion technology by using a special welding machine, which creates a fusion joint that is leak-free and as strong as the pipe.
* Can provide variety of choice. The HDPE fittings include different type of fittings for pipeline, such as HDPE butt fusion fittings, HDPE electrofusion fittings, HDPE compression fittings, Mechanical fittings..etc. People can take the best choice based on their budget, construction environment.
* Safety of potable water: HDPE fittings are made of PE100 material, which is hygienic and suitable for portable water transportation.
* Resistance to corrosion, tuberculation, deposits: HDPE fittings are free to corrosive mediums.

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.
