Raw materials quality control
Raw materials play a key role in the quality and functionality of PVC pipes and fittings and PE pipes. Therefore, during their journey from arrival at factory gates to the molds that shape them into final products, these materials undergo the following test, which have considerably helped the formulation design team and the production department.
• Density measurement
• Oxidation induction time (OIT) measurement to check for thermal stability
• Melt flow rate (MFR) test
• K-value test
• Malleability control
• Moisture content measurement
• Soot percentage measurement
UPVC Pipe and Fitting Tests
• Dimension measurement and appearance inspection
• Impact resistance test
• Vicat softening temperature measurement
• Resin percentage measurement
• Tests for resistance against dichloromethane
• Ring stiffness measurement
• Thermally‑induced longitudinal contraction test
• Marking test
PEP Pipe Tests
• Melt flow rate (MFR) test
• Soot percentage measurement
• Soot dispersion test
• Hydrostatic pressure test
• Fracture test
• Tensile strength measurement
• Marking test
All the products by Khuzestan Hose and Pipe Co. are certified by competent authorities and fully compliant with the relevant standards. These UPVC pipes and fittings and their O‑rings are especially chemical resistant at various temperatures, which makes them perfect replacements for expensive steel pipes. You can contact our sales or R&D department at Khuzestan Hose and Pipe Co. to ensure our products chemical resistance. The relevant certifications are available as follows.
