How can we connect HDPE pipes to PVC pipes?

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.

What's the warranty can SUNPLAST provide?

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.

Product Q&A

Q: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?

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.

Q:What kind of HDPE pipe fittings can SUNPLAST provide?

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

Q:Can SUNPLAST provide HDPE fittings in PE80 material?

Yes, PE80 fittings are also possible to us.

Q:Can HDPE fittings made by PE100 material weld with pipes in PE80?

yes, they can be welded together. But, to achieve the best welding results, we recommend to weld PE80 pipes with PE80 fittings.

Q:Can HDPE fittings connect to PVC pipe? Or can HDPE fittings connect to PPR pipe?

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