What is PVC Piping system?

The POLYGON PVC Piping System is a comprehensive solution manufactured by Polygon Pipe, specializing in PVC-based drainage pipes, fittings, and electrical conduits. The system includes PVC-U (unplasticized polyvinyl chloride) pipes designed for durability, corrosion resistance, and efficient fluid transport. Products range from standard drainage pipes to specialized noise-reducing spiral pipes and electrical conduits, all certified with quality standards (e.g., CNAS laboratories).

The Category of PVC Piping system

The PVC Drainage Pipe Series

PVC-U Drainage Pipes:

Standard pipes available in sizes from DN40 to DN200.

Noise-Reduction Pipes:

PVC structural wall drainage pipe, PVC spiral drainage pipe and UPVC structure wall spiral drainage pipe for quiet operation.

Renovation Systems:

PVC Flat pipes for floor drain relocation.

PVC Drainage Fittings:

Over 31 series of components, such as elbows, tees, reducers, traps, and cleanouts. Examples include 45° elbows, equal tees, P-traps, and vent caps.

Shrinkage Pipe Fittings:

Designed for reduced space requirements, e.g., Tee-Lower Shrinkage.

Accessories:

Clamps, rings, and floor drains (e.g., balcony floor drains).

The PVC Electrical Conduit Series

PVC Electrical Conduits

Available in Light, Middle, and Heavy grades, with sizes from DN16 to DN50.

Transparent Conduits

For easy wire inspection and distinction between strong/weak electricity

PVC Electrical conduit fittings

Couplings, elbows, tees, junction boxes (e.g., gang boxes), and saddle clamps.

Specialized Components:

Such as radius bends, bypass bends, and audio-visual gang boxes.

Product Advantages

Product Advantages of PVC Drainage Pipe Series

High Mechanical Strength:
Resists external pressure, impact, and tensile stress, ensuring durability.

Corrosion and Chemical Resistance:
Excellent performance in acidic/alkaline environments, outperforming steel pipes.

Smooth Water Flow:

Non-scaling walls with low fluid resistance (roughness coefficient lower than steel or cement pipes).

Lightweight:
Density is 1/5 to 1/6 that of steel pipes, reducing transport and installation costs.

Noise Reduction:

Spiral structures (e.g., in hollow spiral pipes) minimize water flow noise.

Easy Installation:
Bonded connections with good sealing; lightweight design allows for quick handling.

Quality Assurance:
Supported by CNAS laboratories for full-process quality control.

Product Advantages of PVC Electrical Conduit Series

Flame Retardancy:

Self-extinguishing when removed from flames, ensuring safety.

Insulation Protection:

Excellent insulation properties prevent leakage and electric shocks.

Easy Bending:

Can be manually shaped at room temperature using bending springs.

Corrosion and Insect Resistance:

Durable in various environments, unlike metal conduits.

High Visibility:

Transparent conduits allow for easy inspection and maintenance.

Cost-Effective:

Lightweight and easy to install, reducing labor costs.

Application

Application of PVC Drainage Pipe Series

Building Drainage:
Used in residential and commercial projects for toilets, sinks, and wastewater systems.

Renovation Projects:
Flat pipes enable flexible adjustment of floor drain positions in retrofits.

Industrial Settings:
Suitable for chemical plants due to acid/alkali resistance.

Noise-Sensitive Areas:
Hospitals, hotels, and apartments benefit from noise-reducing pipes.

Urban Infrastructure:
Applied in public drainage systems and municipal projects.

Application of PVC Electrical Conduit Series

Urban Power Grids:
Used in construction and renovation of city electrical networks.

Industrial and Commercial Projects:
Applicable in industrial parks, airports, bridges, and postal telecommunications.

Building Wiring:
For residential and commercial electrical systems, including hidden conduits.

Safety-Critical Areas:
Hospitals, schools, and public facilities due to flame-retardant properties.

Audio-Visual Systems:
Special gang boxes for multimedia installations.

FAQ

For PVC Drainage Pipe Series

Q1: How do I connect PVC drainage pipes securely?

A: Use solvent cement—apply to the socket and pipe end, then twist for even distribution. Allow 30-60 minutes for curing.

Q2: Can PVC drainage pipes handle high-temperature wastewater?

A: PVC-U pipes are suitable for temperatures below 60°C; avoid direct exposure to heat sources.

Q3: Are noise-reducing pipes compatible with standard fittings?

A: Yes, but for optimal performance, use specialized silencing fittings like Silencing Tees.

Q4: What is the best way to cut PVC pipes without damage?

A: Use a saw for clean cuts, then bevel edges at 15° to prevent burrs.

Q5: How do I prevent leaks in bonded connections?

A: Ensure surfaces are clean and dry before gluing; test-fit parts first.

Q6: Can flat pipes be used in new constructions?

A: They are primarily for renovations; standard pipes are recommended for new builds.

Q7: What maintenance is required for PVC drainage systems?

A: Periodic inspections for blockages or leaks; no special maintenance needed due to corrosion resistance.

For PVC Electrical Conduit Series

Q1: How do I bend PVC conduits without breaking them?

A: Insert a bending spring inside and shape manually at room temperature.

Q2: What is the difference between Light, Middle, and Heavy grade conduits?

A: Heavy grade has thicker walls for higher impact resistance; choose based on application demands.

Q3: Can transparent conduits be used outdoors?

A: Yes, they are UV-resistant and suitable for outdoor use, but check local standards.

Q4: How do I distinguish between strong and weak electricity conduits?

A: Red conduits are for strong electricity (e.g., power lines), blue for weak electricity (e.g., data cables).

Q5: What tools are needed for conduit installation?

A: Basic tools like saws, glue guns, and bending springs; follow the installation guide for steps.

Q6: How do I prevent conduit damage during installation?

A: Avoid over-tightening clamps and use rubber pads with metal brackets.
