Pipe Type | Performance & Advantages | Main Application Fields |
PP Pipe (incl. PP-R) | Good heat resistance (PP-R resists 70°C hot water long-term), corrosion-resistant, non-toxic, smooth inner wall (no scaling), lightweight, easy to install (hot-melt connection), long lifespan (up to 50 years), cost-effective. | Building cold/hot water systems, drinking water pipes, industrial pipelines (non-high-temperature/strongly corrosive media), agricultural irrigation. |
Aluminum-Plastic Composite Pipe | Composite of plastic and aluminum, good insulation, wide temperature range (-40°C to 95°C), impact-resistant, bendable without rebound, flexible installation, combining metal and plastic advantages. | Residential cold/hot water pipes, central air-conditioning pipelines, solar water systems, floor heating branches. |
Copper Pipe | High strength, resistant to high temperature/pressure, strong antibacterial property, corrosion-resistant, long lifespan (up to 100 years), stable water quality, suitable for various fluids. | High-end building water supply, medical pipelines, air-conditioning refrigeration pipes, precision instrument cooling systems (high water quality requirements). |
Welded Steel Pipe | High strength, good pressure resistance, strong deformation resistance, wide pressure range, moderate price; needs anti-corrosion treatment (e.g., galvanizing), poor corrosion resistance. | Fire-fighting systems, industrial high-pressure fluid transmission, large water supply/drainage projects, low-pressure gas pipelines. |
PVC-C Water Supply Pipe | High strength, heat-resistant (60°C long-term use), corrosion-resistant (acid/alkali), flame-retardant, smooth inner wall (low water resistance), easy to install. | Transport of corrosive media in chemical/pharmaceutical industries, industrial cooling water pipes, building drainage, seawater transmission. |
Polyethylene (PE) Pipe | Good flexibility, strong impact resistance, low-temperature resistant (-70°C usable), chemical corrosion-resistant, non-toxic, high hot-melt joint strength, lightweight, low laying cost. | Urban water supply/drainage, gas transmission, agricultural irrigation, municipal engineering, buried water pipelines. |
