Actual inside diameter, outside diameter, profile dimensions, tolerance, mass and stiffness requirements should be confirmed in the technical datasheet for the selected configuration.
Ring Stiffness and Project Selection
Available configurations include SN4, SN8 and SN16, subject to the applicable standard and pipe design.
The appropriate stiffness class should be selected according to the complete installation system rather than pipe diameter alone. Important factors include:
- Burial depth
- Soil conditions
- Bedding and backfill
- Compaction
- Groundwater
- Traffic and surface loading
- Trench conditions
- Applicable engineering standards
For project quotations, buyers can provide these details so the pipe configuration can be reviewed before production.
Quality and Manufacturing
Kaisheng's quality control process covers raw material inspection, extrusion and forming control, dimensional and appearance inspection, project-specific testing, and final loading inspection.
Our production capacity is up to 500 tons/day, depending on product specifications and order volume.
Buyer-appointed third-party inspections, such as SGS or BV, can be arranged by agreement before shipment.
Packaging, Shipping and Lead Time
Pipes are bundled and secured for international transportation. Depending on pipe dimensions and configuration, nesting and 40ft High Cube container loading may be used to improve loading efficiency.
Export documents may include Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin where required, product documentation and applicable inspection or test reports.
Typical production lead time for standard orders may be approximately 7–15 days after specifications, quantity, payment terms and production scheduling are confirmed. Customized or large-volume orders may require additional time.
Customization and Technical Support
Customization can be discussed for diameter, length, ring stiffness, jointing system, markings, meter identification, customer information, packaging and loading requirements.
Technical documents may include product datasheets, dimensional drawings, installation information and available test documentation. CAD or BIM-related information can be discussed for project requirements.
