Understanding The Plastic Pipe Testing Machine

Understanding the Plastic Pipe Testing Machine

Plastic pipe testing machines play a critical role in ensuring the safety, reliability, and longevity of plastic piping systems used in water supply, gas distribution, sewage, and industrial processes. Shijiazhuang Zhongshi Testing Machine Co., Ltd. offers a robust range of machines designed specifically for evaluating the mechanical and performance characteristics of plastic pipes under real-world conditions.

Key Functionalities

• Pressure Endurance Testing: The machine applies internal pressure to plastic pipes to determine burst pressure and leakage thresholds. It can simulate both steady and cyclic pressure conditions, enabling manufacturers to validate pipe integrity over extended service life.

• Dimensional Accuracy Verification: Integrated laser or contact sensors measure pipe dimensions (outside diameter, wall thickness, ovality) to confirm compliance with international standards such as ISO 9080 and ASTM D1598.

• Creep and Long-Term Performance: Under sustained pressure and elevated temperatures, the machine evaluates permanent deformation (creep) and residual strength, providing data for lifetime prediction.

• Temperature-Controlled Testing: Equipped with heating jackets or environmental chambers, the system can test pipes at temperatures ranging from 20 °C to 95 °C, reflecting conditions encountered in hot-water or solar-thermal applications.

Technical Specifications

• Pressure Range: Up to 25 MPa (depending on model)

• Test Chamber Diameter: 20 mm – 250 mm

• Temperature Control: ±0.5 °C accuracy, 20 °C – 95 °C

• Data Acquisition: Real-time digital recording of pressure, deformation, and temperature, with exportable CSV or PDF reports

• Control Interface: Touchscreen HMI with programmable test sequences and automatic safety shutdown

Industry Applications

• Municipal Water Supply: Verifying that drinking-water pipes can withstand internal pressures and temperature fluctuations.

• Gas Distribution: Ensuring natural gas pipelines meet safety regulations without defects.

• Chemical Processing: Testing resistance to corrosive fluids and pressure variability.

• Construction and Infrastructure: Certifying underground drainage and sewage piping for load-bearing capacity and leak-tightness.
