Product Overview
PVC Culvert Pipe is a PVC-U double-wall corrugated drainage pipe for road drainage, municipal stormwater systems, agricultural drainage, and underground culvert projects.
The pipe uses a smooth inner wall and corrugated outer wall, with nominal diameters of DN100–DN800 mm and project-specific sizes up to DN1200 mm. It is used for non-pressure gravity drainage and underground water conveyance applications.

Key Performance Benefits
PVC Culvert Pipe features a smooth inner wall for efficient water flow and SN2 to SN12.5 stiffness options for different underground load conditions. PVC-U offers excellent resistance to soil and drainage corrosion for long-term use. The lightweight socket-and-rubber-ring connection makes handling and installation easier, with less need for specialized equipment on site.

Quality Assurance Process
Raw Material Inspection: Verification of primary PVC-U resin purity, stabilizer ratios, and additive blending.
Dimensional & Visual Checks: Continuous laser monitoring of wall thickness, inside/outside diameter, and structural integrity during extrusion.
Mechanical Testing: Regular execution of Ring Stiffness Tests (per ISO 9969 / ASTM D2412), Impact Resistance Tests, and Pipe Flexibility Tests.
Sealing Integrity: Verification of socket dimensions and elastomeric ring tolerances to guarantee zero leakage under joint deflection.
Third-party inspection (SGS, BV, Intertek, etc.) prior to shipment is fully supported upon request.
Customization & Supply Capability
Dimensional Adjustments: Tailored wall thicknesses and non-standard diameters up to DN1200 mm.
Stiffness Optimization: Engineered ring stiffness classes tailored to specific burial depths and surface load calculations.
Branding & Marking: Custom laser-printed text, project tracking codes, and logo embossing on the pipe surface.
Packaging & Logistics: Optimized container loading configurations (nesting smaller pipes inside larger ones to minimize freight costs) and export-grade bundling.
Production lead time typically ranges from 10 to 25 days, backed by comprehensive shipping and logistics support.
Certifications and Technical Documentation
Kaisheng can provide available product documentation, Technical Data Sheets (TDS), dimensional blueprints, installation guidelines, and standard factory test reports. If a project requires specific EN/ISO/ASTM standards, third-party testing, or other certifications, requirements can be confirmed prior to purchase.
Installation Guidance
The standard connection uses a socket-and-rubber-ring sealing system. The socket and sealing ring should be cleaned thoroughly before assembly, and the pipe must be inserted to the specified depth according to standard underground trenching and backfilling codes.
Frequently Asked Questions
Q: What is the minimum order quantity (MOQ) for customsized or standard PVC culvert pipes?
A: Our standard MOQ is typically one 40ft highcube container, but trial or mixedsize orders can be negotiated based on current factory production scheduling.
Q: What are the standard payment terms accepted for international orders?
A: We commonly accept T/T (Telegraphic Transfer) with a 30% deposit and the balance paid against the copy of the Bill of Lading, or L/C at sight for qualifying contracts.
Q: How are container space and shipping costs optimized for longdistance export?
A: We utilize a professional nesting method by sliding smaller diameter pipes inside larger ones to maximize 40HC container volume and significantly lower freight expenses per meter.
Q: Can your factory accommodate thirdparty preshipment inspections (PSI) by agencies like SGS or BV?
A: Yes, we fully cooperate with designated thirdparty inspection bodies for quality and quantity checks prior to final container loading.
Q: What is the standard production lead time for a full container load (FCL)?
A: Regular production is completed within 10 to 25 days following the receipt of the advance payment and final drawing confirmation.
Q: Do you offer OEM or privatelabel branding services on the pipe exterior?
A: Yes, we provide custom inkjet printing on the pipe body to display your company name, project reference code, or specific standard markings.
Q: What type of export packaging is used to protect the pipe sockets during transit?
A: Pipe ends and sockets are protected with specialized plastic caps or secure bundling straps, and rubber sealing rings are packed separately in sealed export cartons.
Q: Can you provide raw material test certificates and factory inspection reports with the shipment?
A: Yes, a comprehensive Mill Test Certificate (MTC) and factory quality inspection report are provided alongside commercial shipping documents for every batch.
Q: Which departure ports do you normally use for maritime shipping?
A: We routinely ship via major Chinese ports such as Tianjin, Qingdao, or Shanghai depending on the most costeffective maritime route for the destination country.
Q: Are physical product samples available for laboratory evaluation or client approval?
A: Yes, free short segment pipe samples can be supplied upon request, with courier freight costs collected or prepaid by the inquiring buyer.
