PVC-U Drainage pipe

1. Excellent physical properties ensure stable operation of the drainage system

Corrosion resistance and aging resistance: PVC-U material has strong chemical stability and can withstand the erosion of various chemical substances such as acids, alkalis, and salts. It does not rust like metal pipes and is not corroded by long-term exposure to sewage (including oil, detergents, etc.). At the same time, its excellent UV resistance and weatherability ensure a service life of over 50 years in indoor and outdoor environments, reducing the frequency of subsequent replacements.

Smooth inner wall and efficient drainage: The inner wall of the pipe is extremely smooth (with a roughness coefficient of only 0.009), resulting in low water flow resistance and resistance to scaling. This effectively prevents debris from adhering and blocking the pipe, ensuring smooth drainage. Compared to traditional cast iron pipes, it reduces the maintenance costs associated with dredging due to blockages.

High mechanical strength and good impact resistance: The pipe material possesses a certain degree of rigidity and toughness, capable of withstanding significant external pressure (such as soil backfilling and ground loads) at room temperature, making it less prone to deformation and cracking. Although it becomes slightly brittle at low temperatures, it can withstand general impacts (such as construction collisions and water flow impacts) during normal installation and use, making it suitable for various scenarios including concealed and exposed installation.

II. Convenient and efficient installation, reducing construction costs

Lightweight and easy to handle: PVC-U has a density of approximately 1.4g/cm³, which is only 1/5 of that of cast iron pipes and 1/3 of that of concrete pipes. It is convenient for transportation and on-site handling, making it particularly suitable for construction in high-rise buildings and confined spaces, reducing manual labor intensity.

The connection method is simple and reliable: it adopts socket-and-spigot bonding or rubber ring sealing connection, and the operation is convenient:

When bonding, simply apply special PVC glue to the joint, align and insert it for quick fixation. No complex processes such as welding or thread machining are required. Ordinary workers can operate after simple training, significantly shortening the construction period.

The rubber ring connection possesses a certain degree of elasticity, enabling it to accommodate pipeline expansion and contraction caused by minor settlement or temperature variations. With its excellent sealing performance, it prevents water leakage.

Convenient cutting and processing: It can be easily cut with a regular hand saw, without requiring special tools. It can be flexibly adjusted according to the on-site dimensions, reducing material waste caused by measurement errors.

III. Environmental protection and safety, meeting modern architectural requirements

No harmful substance release: High-quality PVC-U drainage pipes are produced using environmentally friendly raw materials, free of heavy metals such as lead and cadmium. They do not release toxic substances that pollute water or air during use, meeting the hygienic standards for indirect contact with drinking water (such as GB/T 10002.1). They are suitable for households, hospitals, food factories, and other places with high environmental protection requirements.

Good flame retardancy: PVC-U is a non-flammable material with an oxygen index of ≥32. It is not prone to burning when exposed to fire, and when it does burn, it produces little smoke and low toxicity, which can delay the spread of fire and meet building fire safety standards.

Recyclable: After being scrapped, the pipe materials can be recycled and reprocessed, reducing construction waste pollution and aligning with the sustainable development concept of green buildings.

4. Low comprehensive cost and outstanding cost-effectiveness

Moderate procurement cost: Compared to metal pipes such as stainless steel pipes and cast iron pipes, PVC-U drainage pipes are priced lower, offering a significant advantage in initial procurement costs.

Low maintenance cost: Due to its corrosion resistance, resistance to blockage, and long service life, there is almost no need for frequent maintenance and replacement in the later stages, which can save a significant amount of maintenance costs (such as labor and material costs for rust removal, dredging, and replacement of pipelines).

Low life cycle cost: With a service life of over 50 years, the total cost of "procurement + installation + maintenance" is significantly lower than that of traditional pipes, offering outstanding long-term cost-effectiveness.

5. Wide range of applicable scenarios, complete specifications and categories

Full-scenario coverage: It can be used for building indoor and outdoor drainage (such as domestic sewage, rainwater, and air conditioning condensate), industrial wastewater discharge (non-corrosive), agricultural irrigation, and other systems, suitable for various projects such as residential buildings, commercial buildings, municipal engineering, and factories.

Rich specifications: The pipe diameter ranges from DN50 to DN630 (or even larger), and the wall thickness is divided according to pressure levels (such as SDR26, SDR33, etc.), meeting different drainage capacity requirements. At the same time, a complete set of pipe fittings (elbows, tees, traps, inspection ports, etc.) is provided to achieve functions such as pipeline turning, branching, water storage and odor prevention, ensuring system integrity.
