Shanxi Kaisheng Plastic Co., Ltd. is one of the most reliable manufacturers and suppliers of HDPE pipe fittings in China. Please feel free to buy CE approved HDPE pipe fittings in stock here from our factory. All customized products are with high quality and competitive price. Contact us for quotation.
Product Overview
Our HDPE Pipe Fittings are manufactured for joining, branching, reducing and changing the direction of polyethylene piping systems. Available in HDPE/PE100 configurations for water supply, irrigation, drainage, mining and industrial piping projects. All products strictly comply with ISO 4427 / EN 12201 international manufacturing standards.
Engineered Around the Practical Requirements of HDPE Piping
Inner diameters are precision-engineered and CNC-machined to match standard metric pipes, helping minimize step-down turbulence and unnecessary head loss.
A controlled melt flow rate (MFR ≤ 0.4 g/10 min at 190°C/5 kg) supports stable and uniform bead formation during both butt fusion and electrofusion processes.
UV-stabilized compounding, with carbon black dispersion ≥ 2.0%, helps protect fittings against solar degradation during extended outdoor storage and installation.
Optimized cooling cycles help reduce post-molding volumetric shrinkage, supporting consistent wall thickness and controlled ovality within specified tolerances.

Manufacturing & Quality Control
Certified Raw Material: Sourced exclusively from certified petrochemical producers with verified density and MFR test logs (PE100 virgin resin).
Automated Production: High-tonnage CNC injection molding presses with closed-loop temperature and injection-pressure control.
Dimensional Inspection: Ultrasonic wall thickness gauges and digital calipers check ovality, wall thickness and outer diameter tolerances for each production run.
Pressure Testing: Hydrostatic burst, short-term pressure resistance and longitudinal reversion tests conducted according to ISO 1167 requirements.
Batch Traceability: Laser-etched matrix codes link each fitting to its raw material lot, production date and operator records.
Ordering, Logistics & Custom Requirements
Free Sample Program: Material coupons and standard-size sample fittings available for third-party laboratory testing and evaluation.
Specification Review: Pre-order technical validation covering fluid characteristics, operating pressure, maximum/minimum thermal thresholds, and installation methods.
Scalable Bulk Production: High-capacity factory output with standard lead times ranging from 15 to 30 days depending on order scale.
Export-Grade Packaging: Heavy-duty reinforced wooden crating and palletization engineered to withstand multi-modal maritime transit and rough port handling.
OEM / ODM Customization: Support for custom laser marking, specific project color stripes (e.g., blue for water, yellow for gas), and non-standard engineering designs.
Frequently Asked Questions
Q: What is the service life of HDPE dredging pipes?
A: Made from virgin PE100 resin, they offer a design life of 50+ years, providing superior resistance to abrasion and corrosion compared to steel alternatives.
Q: How are marine floating HDPE pipes connected on-site?
A: They are typically connected using stub ends with backing steel flanges, bolts, and rubber gaskets, or via flexible quick-release couplings for rapid offshore deployment.
Q: Do you support third-party factory inspections?
A: Yes. We welcome inspections by SGS, BV, or TUV, and provide complete factory test reports (hydrostatic pressure, dimensions, and material density) before shipment.
Q: What is the difference between straight pipes and floating coiled pipes?
A: Straight pipes are rigid and ideal for fixed land-based slurry lines, while floating coiled pipes offer high flexibility and buoyancy for offshore marine operations.
Q: What accessories are included for a complete dredging pipeline system?
A: We supply matching system components, including steel backing flanges, rubber gaskets, bolts, nuts, and high-buoyancy marine floaters.
Q: How do you handle shipping and loading for large-diameter pipes (DN800–DN1200)?
A: Smaller pipes are nested inside larger ones to maximize container space, while large-diameter sizes are shipped via open-top containers or bulk cargo vessels to minimize freight costs.
Q: What are your supported trade terms and payment methods?
A: We support standard trade terms including FOB, CIF, and DDP (shipping globally). For payment, we accept T/T (Telegraphic Transfer) and L/C at sight. Flexible terms can be discussed for long-term partners.
