Plastic Pipe Testing Equipments Factory

Plastic Pipe Testing Equipments

Plastic piping systems are widely used in water supply, wastewater management, gas distribution, and industrial processing. Ensuring pipe strength, leak tightness, and dimensional accuracy is vital for system safety and longevity. Shijiazhuang Zhongshi Testing Machine Co., Ltd. manufactures comprehensive plastic pipe testing equipments tailored to international standards.

Principal Testing Functions

• Hydrostatic Pressure Testing: Continuous and cyclic pressure tests determine burst pressure, minimum burst pressure, and long‑term hydrostatic resistance. Tests conform to ISO 9080, ASTM D1598, and EN 12201.

• Dimensional and Geometric Inspection: Laser micrometers and calipers measure outer diameter, wall thickness, ovality, and length to ±0.02 mm. Data logger maps variation along pipe length.

• Creep Testing: Under sustained pressure and elevated temperature, creep rupture and deformation are recorded. Lifetime prediction algorithms project service life based on stress‑rupture data.

• Impact and Brittleness: Notched‑pipe impact tests assess resistance to crack propagation at low temperatures, per ISO 3127 and ASTM D1790.

Equipment Highlights

• Pressure Range: Up to 25 MPa, with programmable ramp/hold sequences

• Temperature Control: Water baths or heating jackets maintain 20 °C to 95 °C with ±0.5 °C accuracy

• Data System: High‑frequency sampling, multi‑channel recording of pressure, temperature, and deformation; comprehensive report export

Applications and Sectors

• Municipal Infrastructure: Qualifying drinking‑water and sewage pipes for long‑term service under varying pressure and temperature

• Gas Distribution: Certifying PE‑gas lines for leak‑free performance and pressure cycles

• Industrial Plants: Testing chemical‑resistant piping used in processing, cooling, and effluent management

• Renewable Energy: Verifying pipes in solar‑thermal and geothermal installations for temperature‑induced fatigue
