Supplier typeThe supplier is classified as a combined company, with business activities covering wholesale of electrical equipment and the production and processing of plastic machinery, general machinery, and plastic products. Its primary offered product is identified as mechanical equipment, and the English company name is Qingdao Huashida Machinery Co., Ltd.

After-Sales capabilityThe supplier commits to a 12-month guarantee from installation, subject to a maximum of 14 months from delivery, with troubleshooting, qualifying spare parts, and free technical training during the warranty period. It also reports written and followed procedures for service-capability assessment and corrective/preventive actions, although the approved-supplier list lacks signatures or dates.

R&D capabilityThe supplier reports ODM capability and broad design-service support, but states that it had no new products in the past year and no available SDK. These facts show design and ODM service capability but do not demonstrate strong recent product innovation.

Production capacityThe supplier operates five production lines, has six to ten quality-control staff, and reports annual output of 70 plastic pipe extruder sets and 2,000 tons of heat-shrink sleeve. It also reports inventory capability, valid manufacturing contracts with associated subcontractors, and fulfillment within 15 working days in both peak and off-peak periods; however, finished-product inspection has instructions but no written records.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM services, supporting a broad stated ability to adapt products to customer requirements.

Client casesThe supplier reports providing OEM services for well-known brands and has exported for 21 years, with 51%–70% of sales from exports to Southeast Asia, the Middle East, and Europe. These statements indicate international and branded-customer experience, but no specific customer names, projects, or verifiable case details are provided.

Product Q&A

Q:What pipe diameter range does this double wall corrugated pipe line cover?

dia 200-3000mm across 4 models (SKRG-1200 through SKRG-3000), covering small municipal sewage collectors through large-diameter stormwater drainage culverts in one product family.

Q:What materials does this corrugated pipe production line process?

HDPE, PP, and PVC, giving municipal sewage drainage pipe manufacturers flexibility to produce different material specifications from one production line without separate equipment.

Q:What is the Weholite I-Beam structured wall design and why does it matter?

Weholite technology uses an I-Beam hollow structured wall profile, delivering superior ring stiffness (SN4/SN8/SN16) and strength-to-weight ratio versus standard double wall corrugated pipe, while using significantly less raw material per meter than solid-wall alternatives.

Q:What is the service life of HDPE structured wall corrugated pipe produced on this line?

50 years, with full chemical resistance to acids, alkalis, and salts in buried municipal sewage and stormwater drainage service, directly replacing concrete and cast iron pipeline networks.

Q:What ring stiffness classes can this line produce?

SN4, SN8, and SN16, the full range of municipal sewage and stormwater drainage pipe stiffness classes, customizable to project ground load and burial depth specifications.
