Plastic Pipe Testing Equipments Factory China

Plastic Pipe Testing Equipments

Plastic pipes are widely used in water supply, gas distribution, drainage, and industrial fluid systems. Shijiazhuang Zhongshi Testing Machine Co., Ltd. specializes in pipe testing machines that measure pressure capacity, dimensional stability, and long-term durability for pipes made of PE, PVC, PP, PVDF, and other polymers.

Principal Testing Modules

• Hydrostatic Burst and Fatigue Testing: Systems impose both constant and fluctuating pressures up to 25 MPa, identifying burst thresholds and fatigue life under cyclic loading. Controlled dwell times and ramp rates conform to ISO 1167 and ASTM D1598.

• Creep and Stress Rupture: Under sustained pressure and elevated temperatures (20 °C–95 °C), the machine evaluates pipe elongation, permanent set, and time-to-failure to predict service life.

• Dimensional Control: Laser or mechanical probes monitor outer diameter, wall thickness, ovality, and straightness during and after pressure application.

• Leakage and Flow-Through Analysis: High-sensitivity flow meters detect micro-leaks down to 0.01 mL/min, while conductivity probes distinguish fluid ingress.

• Environmental Conditioning: Integrated temperature jackets and circulation baths allow testing under temperature gradients and simulate solar-thermal environments.

Equipment Features

• Pressure Range: 0–25 MPa adjustable, ±0.1% stability

• Temperature Accuracy: ±0.5 °C in environmental chambers

• Pipe Diameter Capacity: 20 mm–315 mm (expandable on request)

• Data System: Multi-channel acquisition, real-time graphing, and customizable report templates

• Safety: Overpressure relief, emergency shutdown, and guard interlocks

Use Cases

• Municipal Water Mains: Verifying resistance to pressure surges, slow crack growth, and thermal expansion

• Natural Gas Pipelines: Testing low-temperature toughness and high-pressure integrity of PE gas mains

• Sewage and Drainage: Assessing pipes for root resistance and long-term deformation under load

• Industrial Transport: Ensuring chemical-resistant pipes perform under variable pressure and temperature

By partnering with Shijiazhuang Zhongshi Testing Machine Co., Ltd., customers benefit from bespoke test fixtures, method development tailored to new polymer blends, and comprehensive training to maintain rigorous pipe testing workflows.
