PE, PVC at PPR Pipe sa Drainage at Sewage System (DWV)

Sa sistema ng pagtutubero ng mga modernong gusali, ang Drain, Basura, Sistema ng vent (DWV) ay ang pangunahing link upang matiyak ang pag-andar at kaligtasan ng kalinisan ng gusali. Bilang mga eksperto sa produksyon ng tubo, we know that the performance differences of pipes made of different materials directly affect the lifespan and maintenance costs of the project. This article will provide an in-depth analysis of the unique advantages and applicable scenarios of Mga tubo ng PE (polyethylene), Mga tubo ng PVC (polyvinyl chloride), and PPR pipes (random na copolymer polypropylene) in DWV systems to help you precisely match project requirements.

Mga tubo ng PVC: The first choice for lightweight and high cost performance

PVC pipes have long dominated the DWV system market due to their lightweight, mababang halaga, and chemical resistance. Its rigid structure effectively resists soil pressure and is suitable for underground drainage pipe installation.

Mga pangunahing pakinabang:

1. Excellent acid and alkali resistance: Can withstand corrosive substances such as grease and cleaning agents in domestic sewage for a long time.

2. Easy to install: The glue bonding process is used, the connection is fast and the labor cost is low.

3. Mababang paglaban sa daloy: The inner wall is smooth, reducing the risk of dirt deposition and the probability of clogging.

Mga aplikasyon:

– Vertical drainage main pipes in residential buildings

– Underground sewage pipe network for commercial buildings

– Branch exhaust lines of the ventilation duct system

Construction tips: Avoid exposure to ultraviolet environments (buried or protected), and the working temperature is recommended to be controlled between -5 ° C at 60 ° C.

Mga tubo ng PE: A flexible and impact-resistant buried solution

High-density polyethylene (HDPE) pipes are known for their exceptional flexibility, freeze crack resistance, at wear resistance, making them particularly suitable for DWV projects in complex terrain and cold regions.

Mga pangunahing pakinabang:

1. Excellent impact resistance: It can withstand ground settlement and vehicle pressure, reducing the risk of pipeline rupture.

2. Zero leakage in hot-melt connection: Seamless connection is achieved through an electric fusion welding machine, eliminating leakage at the interface.

3. Long life design: hanggang sa 50 years or more in the absence of direct ultraviolet radiation.

Mga sitwasyon ng aplikasyon:

– Underground main sewage network in industrial parks

– Connecting pipes for septic tanks in cold regions

– Flexible drainage systems for buildings in seismic zones

Construction tips: Special hot-melt equipment is required, and the construction team must hold PE pipe welding certification.

Mga tubo ng PPR: Green materials that can withstand high temperatures

While PPR pipes are more often used in water supply systems, their heat-resistant, non-toxic and environmentally friendly properties make them stand out in special DWV scenarios.

Mga pangunahing pakinabang:

1. High temperature stability: Can withstand 95 ° C high temperature wastewater (such as laboratory and kitchen drainage) for a long time.

2. Ecological safety: Compliant with food-grade standards, suitable for sensitive places such as hospitals and food factories.

3. Low coefficient of thermal expansion: reduces pipe deformation caused by temperature differences.

Mga sitwasyon ng aplikasyon:

– Hospital high-temperature disinfection wastewater discharge system

Oily wastewater pipelines in food processing plants

– Condensate drainage pipes for solar water heaters

Construction tips: Use hot-melt socket connection and precisely control the heating time to avoid tube wall deformation.
