Does SUNPLAST provide HDPE fittings in PE80 material?

Yes, PE80 fittings are also available from SUNPLAST.

What is the difference between HDPE end cap and HDPE pipe end?

They refer to the same products.

AI-Powered supplier vetting

SummaryThe supplier is a small limited company with 8 employees offering HDPE pipes and fittings. It is identified as a professional technical supplier and provides extensive customization, ODM, and OEM services, including for popular brands. However, it does not provide 3D software design, has not launched new products in the past year, and has no available SDK. Service-management procedures exist for corrective actions and complaint handling, but no written records were provided. The supplier reports no overseas warehouse, showroom, agent, or branch, although it has attended EXCON CAPECO and accepts several trade and payment terms. Financial records are indicated for 2021–2023, but their contents are not provided. No certification information, production scale, or verified customer case details are available.

Supplier typeThe supplier is explicitly identified as a professional technical supplier, operates as a limited company, and offers HDPE pipes and fittings. It is not part of a larger company group and has 8 employees, indicating a small, independent supplier structure.

After-Sales capabilityThe supplier has procedures for handling customer complaints and corrective and preventive actions, but no written records are available. It has no overseas warehouse, showroom, agent, or branch, while its service coverage is reported as zero countries; these limitations constrain demonstrated overseas after-sales support.

R&D capabilityThe supplier provides ODM services and is described as having R&D capability, but it launched no new products during the past year, lacks an available SDK, and does not provide 3D software design. Its digitalization program has started, but ERP, OA, CRM, and SAP systems are not established or used.

Product Q&A

Q:Which SDR of HDPE fittings should be used for SDR13.6-PN12.5 pipe?

To guarantee safety, fittings must have an equal or higher pressure rating than the pipeline. For SDR13.6 pipe, use SDR13.6 or SDR11 fittings. SDR17 fittings are not suitable.

Q:Can HDPE fittings made of PE100 material be welded with PE80 pipes?

Yes, they can be welded together. However, for the best welding results, it is recommended to weld PE80 pipes with PE80 fittings.

Q:How can HDPE pipes be connected to PVC pipes?

Since they are different materials, they cannot be heat-fused. The solution is to use HDPE flange adaptors and HDPE backup flanges to connect to PVC flanges via flanged connection.

Q:What is the warranty period for SUNPLAST HDPE fittings?

All fittings are designed for a 50-year lifetime. SUNPLAST provides a 10-year quality warranty for regular use.

Q:Are SUNPLAST HDPE fittings UV resistant?

Yes, they are UV resistant and stable. Prolonged UV exposure may cause a waxy look on the surface, but this does not affect performance and can be removed before welding.
