Plastic, Steel and Concrete Pipes

In this section, various tests are carried out on various products and uses in Potable water, Sewage, water drainage and Irrigation purposes such as PVC, UPVC, PE & HDPE, Steel and Concrete pipes, the tests that are performed, hydrostatic pressure of pipes, load bearing, welding quality of steel pipe, dichloromethane and impact tests for PPE & PVC pipes etc., all tests are performed according to EN, ISO, ASTM and Palestinian standards

Concrete Pipes Testing

• Concrete mix design, ASTM – C 72
• Compressive strength & water absorption, ASTM – C 72
• Dimensional test, ASTM – C 72
• External load & crushing strength, ASTM – C 497

Steel Pipes (Threaded and none threaded) Testing

• Dimensional and weight tests, PS 186 & PS 141
• Hydraulic Pressure test, PS 186 & PS 141
• Tensile strength test, PS 186 & PS 141
• Threading test, PS 186 & PS 141
• Galvanization and coating thickness test, PS 186 & PS 141
• Crushing test, PS 186 & PS 141

Plastic Pipes Testing

• Dimensional test, ISO 3126
• PVC, PE Pipes – Hydrostatic pressure test (100 Hours, 165 Hours, 1000 Hours), BS EN 920 / ISO 1167
• PVC, PE Pipes –Dichloromethane, BS EN 580
• Thermoplastic pipes- Longitudinal Reversion, ISO 2505-2005
• Thermoplastic Pipes-Impact test of pipes, BS EN 744 / ISO 3126
• Polyolefin pipes and fittings — Determination of carbon black content by calcinations and pyrolysis, ISO 6964–2019

Dichloromethane test is used to determine the resistance of un-plasticized polyvinyl chloride (PVC-U) pipes to dichloromethane (methylene chloride) at a specified temperature (DCMT).
The gelation of PVC is one of the most important product quality considerations as it has an influence on impact strength and resistance to internal pressure.
