What are the uses of PVC pipe?

1. Six Core Functions of PVC Pipe

• Fluid Transport: A safe and efficient "pipeline network"

Water Supply System:

Used for hot and cold water transportation in homes and municipalities (UPVC and CPVC must be distinguished as they have different temperature resistances). Drainage and Sewage:

Building drainage, rainwater pipes, and septic tank connections are corrosion-resistant and resist scale formation.

Industrial Fluids:

Transport of acid and alkali liquids in chemical and electroplating plants (acid- and alkali-resistant PVC pipes are stabilized with special stabilizers).

• Power and Communications Protection: A "safety armor" for cables

Electrical Conduit:

Protecting indoor electrical wiring, flame retardant and fireproof (conforming to GB/T 14823 standards).

Communication Pipeline:

Underground pre-buried pipes for optical fiber and network cables, resistant to pressure and moisture.

• Agricultural Irrigation: The "artery of the field" for water conservation and increased

production

Drip/Sprinkler Irrigation Systems:

Lightweight and easy to lay, with strong weather resistance (applicable to temperatures ranging from -10°C to 60°C). Greenhouses:

Used as frames or water pipes, the cost is only 1/3 that of metal pipes.

• Structural Support: Lightweight building materials

Temporary building frames:

Construction site fencing, exhibition stand supports, removable and reusable.

Furniture DIY:

Cost-effectively create storage racks, lighting fixtures, and more (a popular material among influencers' home renovations).

• Environmental Protection and Healthcare: Specialized Applications

Medical Waste Pipes:

Chemically resistant drainage for hospital laboratories (medical-grade PVC certification required).

Ventilation Ducts:

Laboratory and factory exhaust systems, resistant to acids and alkalis.

• Cost and Construction Advantages

Low Price:

Cost is only 1/2 to 1/3 that of metal pipes.

Easy Installation:

Connect with adhesives or rubber rings, eliminating the need for welding, increasing construction efficiency by 50%.

3.  Core Advantages of PVC Pipe

• Corrosion Resistance: Rust- and scale-resistant, with a lifespan of up to 50 years (compared to 15-20 years for metal pipes).
• Lightweight: Density of 1.4g/cm³, making handling and installation easier (compared to steel pipes of the same specification, which weigh three times as much).
• Insulation and Flame Retardant: Oxygen index ≥45, self-extinguishing when removed from flames (compared to flammable PE pipes).
• Environmentally Friendly and Recyclable: Can be crushed and recycled, RoHS compliant.

4. Precautions for Using PVC Pipe

Temperature Limitation: Ordinary PVC pipe has a long-term operating temperature of ≤60°C. For high temperatures, choose CPVC (resistant to 90°C).

Impact Resistance: Brittleness increases at low temperatures (freeze-resistant PVC-M is recommended in northern regions).

Health and Safety: Water pipes should be lead-free (compliant with GB/T 17219 drinking water standards).
