Key features

High Ring Stiffness, Light Weight: Corrugated profile provides SN4 / SN8 / SN12.5 stiffness at roughly half the weight of solid-wall pipe, cutting freight cost and on-site handling time.

Smooth Hydraulic Inner Wall: Low friction coefficient improves flow capacity, reduces silt accumulation, and makes the pipe self-cleaning in sewage and stormwater service.

Socket Joint with EPDM Gasket: Factory-formed bell and spigot with a locked-in rubber gasket gives a fast, flexible, leak-resistant joint without welding.

UV Stabilized Black Outer Wall: Carbon black masterbatch resists sunlight degradation during storage and installation before backfilling.

Blue Inner Wall for CCTV Inspection: High-contrast inner surface lets inspection cameras easily identify cracks, blockages or deformation after installation.

Chemical & Corrosion Resistant: HDPE withstands aggressive sewage, soil chemicals, acids and alkalis, with a design service life of 50+ years underground.

OEM / ODM Flexible: Custom diameters, ring stiffness grades, lengths, stripe colors, logo marking and packaging available per project.

AI-Powered supplier vetting

SummaryHebei Shentong Plastic Co., Ltd. is a China-based factory established in 2011, with 33 employees and operations in Shijiazhuang, Hebei. The evidence indicates documented procedures for supplier service capability, corrective and preventive actions, complaint handling, and supplier assessment. It reports inventory capacity, lead times within 15 working days in both peak and off-seasons, and access to Tianjin Port. ISO9001:2015 certification is referenced, while no overseas warehouse or showroom capability and no valid manufacturing-capacity contract with an affiliated subcontractor are reported. Innovation evidence is limited: the supplier has one national science and technology progress award but no internationally recognized design awards and no available SDK. Production scope includes plastic pipe production lines and injection molding equipment, but customization capability and customer-specific case details are not sufficiently documented.

Supplier typeThe supplier is identified as a limited company and factory in China, with its operating province and city listed as Hebei and Shijiazhuang. Its stated business scope covers instruments and meters, mechanical equipment, metal products, components, materials, import and export activities, and construction-related services, indicating a manufacturing-oriented and diversified business profile.

CertificationsThe evidence explicitly references an ISO9001:2015 certificate and also states that the company has received ISO9001. Quality assurance in quality-control processes is marked as present, supported by documented procedures and records for relevant service mechanisms.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaint handling, and supplier service-capability assessment. It also reports in-stock service capacity and lead times within 15 working days in both peak and off-seasons, but has no overseas warehouse or overseas showroom.

Production capacityThe supplier reports inventory capacity, quality assurance, and facilities associated with injection molding machines and PPR, PVC, and PE pipe production lines. Its company description also claims well-equipped facilities and quality control across production stages, while the absence of a valid manufacturing-capacity contract with an affiliated subcontractor is a documented limitation.
