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. Use SDR13.6 or SDR11 fittings; SDR17 is not suitable for SDR13.6 pipelines.

Q:What types of HDPE fittings does SUNPLAST provide?

We provide HDPE butt fusion fittings (DN50-800mm), electrofusion fittings (20-630mm), and compression fittings (20-110mm).

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

Yes, they can be welded together. However, for the best welding results, we recommend welding PE80 pipes with PE80 fittings.

Q:Can HDPE fittings connect directly to PVC or PPR pipes?

No. Thermal plastic fittings can only connect to pipes of the same material grade. HDPE fittings connect only to HDPE pipes.

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

Since they are different materials, use a flanged connection. Utilize HDPE flange adaptors and backup flanges to connect to PVC flanges.
