HDPE PIPE Manufacturer for Water, Gas and Industrial Pipelines
Shanghai Zhongsu Pipe Co., Ltd. (ZHSU) is one of China's established HDPE Pipe Manufacturers, producing high-density polyethylene (HDPE) pipe in Shanghai, China, serving municipal water supply, drainage, gas transmission, mining, and nuclear power projects. Our HDPE PIPE range covers PE100 pipes from 20 mm to 1200 mm outside diameter, with pressure ratings from PN6 to PN25 and standard lengths of 5.8 m or 11.8 m. We produce on imported German BATTENFELD lines using Borealis PE100 compounds, and every batch is tested in our CNAS-certified laboratory before dispatch.
As PE100 HDPE Pipe OEM Suppliers, we supply both pipe and matching HDPE FITTING to complete the pipeline system. Our product portfolio also includes PPR PIPE for hot and cold water building services, giving project teams a single source for plastic piping across multiple scopes.
Product Range and Application Fit
We position our HDPE pipe range around three application families: water supply, high-pressure industrial service, and large-diameter transmission. Each family uses the same PE100 base material but differs in wall thickness, pressure class, and dimensional tolerance to match the working conditions of the project.
| Product Family | Typical Size Range | Pressure Class | Primary Applications |
|---|---|---|---|
| HDPE Pipe for Water | 20 mm – 1200 mm | PN6 – PN20 (SDR26 – SDR9) | Municipal water supply, agricultural irrigation, residential and commercial plumbing, rural water network renovation |
| High Pressure HDPE Pipe | 20 mm – 1200 mm | PN20 – PN25 (SDR9 – SDR7.3) | Nuclear power plant cooling and safety lines, mining slurry transport, industrial process water, trenchless installation |
| Large Diameter HDPE Pipe | Up to 1200 mm OD | PN6 – PN16 | Main water transmission, sewage disposal, large-scale drainage, nuclear power plant SWS siphon renovation |
For building services where hot water or heating is involved, our PPR PIPE FOR HIGH TEMPERATURE WATER and PPR PIPE FOR WATER SUPPLY ranges complement the HDPE line. HDPE remains the preferred choice for buried, long-run, and large-diameter pipelines because of its flexibility, fusion-jointed leak-free performance, and resistance to corrosion and ground movement.
Material and Manufacturing Control
All HDPE pipes are produced from 100% imported PE100 compound sourced from Borealis and South Korean suppliers. The black PE100 material delivers low-temperature crack resistance, UV stability, and food-grade safety for potable water contact. We do not use reprocessed or blended regrind in pressure pipe production.
- Extrusion on imported German BATTENFELD lines for consistent wall thickness and roundness.
- In-line dimensional monitoring and surface inspection throughout the run.
- CNAS-certified laboratory testing: hydraulic pressure, watertightness, tensile strength, and anti-aging.
- 100% pre-delivery inspection on finished pipe, with batch traceability from raw material to dispatch.
Our quality management system is certified to ISO 9001, ISO 14001, and OHSAS 18001. Products are manufactured to ISO 4427, DIN 8074/8075, and GB/T 13663-2000, and CE certification is available for applicable markets.
Critical Specifications and Configuration Options
When we prepare a proposal, we confirm the working pressure, fluid type, installation method, and site temperature range to select the correct SDR and wall thickness. The table below summarises the specification variables we use to configure each order.
| Parameter | Options / Range | Notes |
|---|---|---|
| Material grade | PE100 (black), HDPE 4710 for high-pressure service | Borealis and South Korean compounds |
| Outside diameter | 20 mm to 1200 mm | Full size range for large-scale transmission |
| Pressure rating | PN6, PN8, PN10, PN12.5, PN16, PN20, PN25 | Selected by SDR and design pressure |
| Standard length | 5.8 m or 11.8 m | Custom lengths on request |
| Connection method | Socket fusion, butt fusion | Leak-free joints; no mechanical couplings required |
| Working temperature | Up to 50°C continuous | Suitable for buried and open-air installation |
| Service life | Up to 50 years | Under rated pressure and temperature conditions |
For high-pressure applications, we supply High Pressure HDPE Pipe in SDR7.3 and SDR9 with wall thicknesses engineered for cyclic pressure service. For standard water supply, HDPE Pipe for Water covers the full PN6–PN20 range.
Installation, Integration and Site Support
HDPE pipe is installed by socket fusion or butt fusion, producing a continuous, joint-free pipeline that resists leakage and root intrusion. The material's flexibility allows trenchless methods such as horizontal directional drilling and pipe bursting, reducing excavation cost in urban or environmentally sensitive areas.
- Lightweight coils and straight lengths reduce handling equipment requirements.
- Butt fusion parameters are documented for each SDR and diameter to support consistent field joints.
- Pipes tolerate ground settlement, seismic movement, and wide temperature variation without cracking.
- No internal scaling or corrosion, maintaining flow capacity over the service life.
We provide fusion procedure guidance and can review project-specific installation requirements during the quotation stage. For projects requiring fittings, our HDPE FITTING range includes couplings, elbows, tees, and reducers matched to the pipe dimensions and pressure class.
Quality Assurance and Acceptance Testing
Every production batch is sampled and tested in our CNAS-accredited laboratory. During extrusion, we conduct inspections at regular intervals to verify wall thickness, diameter, and surface quality. Finished pipes undergo hydraulic pressure testing, watertightness testing, tensile testing, and anti-aging testing before release.
We issue factory inspection reports with each shipment. For project acceptance, we can provide test data and certificates covering material grade, dimensional checks, and pressure performance. Our quality management system is certified to ISO 9001, ISO 14001, and OHSAS 18001, and CE certification is available for applicable product scopes.
Information We Use to Configure Your Solution
To prepare an accurate HDPE pipe quotation and configuration, we need the following project inputs. Providing these details at the enquiry stage allows us to confirm the correct SDR, length, and fitting schedule without back-and-forth.
- Fluid type and concentration (water, gas, slurry, chemical).
- Design working pressure and maximum surge pressure.
- Required outside diameter and total linear metres per size.
- Installation method: open trench, burial, or trenchless.
- Site temperature range and soil conditions.
- Connection method preference: socket fusion or butt fusion.
- Fitting requirements: couplings, elbows, tees, reducers, and quantities.
- Trade terms (FOB, CIF, CNF) and destination port.
- Any applicable project specifications or standards to comply with.
Our standard delivery time is typically 15 days, depending on order volume and current production schedule. We maintain sufficient inventory of regular pipes and fittings to support fast turnaround. OEM and ODM are supported for private-label and custom-specification orders.
Packaging, Documentation and Serviceability
Pipes are bundled and wrapped in woven bags for transport protection. Fittings are packed in transparent plastic bags in specified quantities and then placed in dedicated cartons. This packaging protects against UV exposure, impact, and contamination during shipping and storage.
We provide product documentation including material certificates, test reports, and installation guidelines. Our sales and technical team supports order tracking with regular production updates and photos every 2–5 days. If you require video verification of production progress, we can arrange that during the manufacturing window.
Frequently Asked Questions
What is the maximum diameter of your HDPE pipe?
