PVC pipes are plastic pipes manufactured through high-temperature extrusion using polyvinyl chloride (PVC) resin as the primary raw material, combined with additives such as stabilizers and lubricants; they account for approximately 40% of the domestic pipe market. Based on their application, they are primarily categorized into three types:

Type	Implementation Standard	Application Scenario	Normal Service Life
PVC Water Supply Pipe	GB/T 10002.1-2023	Municipal water supply, potable water transport	≥50 years
PVC Drainage Pipe	GB/T 5836.1-2018	Building drainage, municipal sewage	≥40 years
PVC Electrical Conduit	JG 3050-1998	Residential wiring, engineering cable routing	≥30 years

Key purchasing tips: ① Check product labeling (manufacturer details and applicable standard numbers); ② Inspect the appearance (smooth surface, free of bubbles or indentations, and uniform wall thickness); ③ Request test reports and qualification certificates from the brand; ④ Retain proof of purchase to ensure after-sales support. High-quality PVC pipes feature a tensile strength of ≥40 MPa and a wall thickness tolerance within ±0.2 mm; inferior products made from recycled waste have a tensile strength of ≤25 MPa and a lifespan of only 5–10 years.
