Professional FAQ: UPVC Electrical Pipe Technical Terms
Q1: What is the advantage of "unplasticized" in UPVC for electrical pipes?
Unplasticized means no plasticizers are added, resulting in a rigid, highly durable pipe with excellent chemical and electrical properties, ideal for protective conduit applications.
Q2: What are the typical sizes available for UPVC electrical pipe?
Standard sizes range from OD 16mm to 110mm, with nominal wall thickness from 1.5mm to 7.5mm. Custom sizes are available for large projects.
Q3: Which certification standards are most relevant to UPVC electrical pipe?
IEC 61386 (conduit systems), ISO 1452 (piping systems), UL94 V-0 (fire resistance), and RoHS (hazard control) are key standards that ensure safety and performance.
Q4: What installation guidelines should be followed for UPVC electrical pipe?
Always cut with pipe cutters, de-burr ends, use the correct solvent cement for joints, and adhere to pull-in force and bending radius recommended in IEC standards to avoid micro-cracks.
Q5: How does UPVC pipe resist corrosion compared to steel?
UPVC is inherently resistant to most acids, bases, salts, and industrial gases, whereas steel corrodes without protective coating—making UPVC ideal for harsh environments.
Q6: Can UPVC electrical pipe be used for underground installations?
Yes, provided the correct wall thickness is selected for burying depth and soil load, and connections are fully solvent welded for water ingress protection.
Q7: What testing methods ensure UPVC pipes' performance?
Hydrostatic pressure, impact resistance, dielectric strength, and fire retardancy tests are conducted per ISO/IEC and ASTM standards with batch test reports available.
