Comprehensive Testing Protocols
Quality assurance is paramount in uPVC pressure pipe manufacturing, especially for applications in water supply where failure can have significant consequences. Sri Balaji Plastics Private Limited implements a multi-tier quality control system that includes:
1
Raw Material Inspection:
All incoming materials undergo rigorous checks to verify compliance with specifications before being accepted for production.
2
In-Process Controls:
Critical parameters including melt temperature, extrusion speed, cooling temperature, and dimensions are continuously monitored throughout the production process.
3
Finished Product Testing:
Completed pipes undergo comprehensive testing including:
- Hydrostatic Pressure Testing: Pipes are subjected to internal pressures significantly higher than their rated capacity to verify strength and leak resistance
- Dimensions Verification: Wall thickness, outer diameter, and concentricity are measured to ensure compliance with standards.
- Impact Resistance Testing: Notched impact tests determine the material's toughness and resistance to brittle fracture.
- Tensile Testing: Mechanical properties including yield strength and elongation are verified.
4
Long-Term Testing:
Samples undergo extended pressure testing to validate long-term performance and durability under continuous stress.
