Compared to traditional pipes, PVC-U pipes offer advantages such as light weight, corrosion resistance, low flow resistance, energy saving, quick installation, and low cost, leading to their widespread adoption and significant benefits. my country began piloting PVC-U pipe applications in municipal and building engineering projects in the 1980s. After decades of promotion, PVC-U pipes have achieved sustained development and have become an indispensable product in civil buildings and home drainage systems.

The inner and outer surfaces of the pipes should be smooth, free of bubbles and cracks, with uniform wall thickness and color. The deflection of straight pipe sections should not exceed 1%. Fittings should be regular in shape, smooth, and free of burrs. The socket should be tapered and matched with the spigot. During transportation, the product must not be subjected to severe impacts, throwing, or heavy pressure. The storage area should be flat, with a stacking height not exceeding 1.5m, and at least 1m away from heat sources. When stored outdoors, the pipes must be covered to prevent exposure to direct sunlight.

1. Production Standards

Building drainage pipes are manufactured and inspected according to national standard GB/T5836.1-2006; building drainage pipe fittings are manufactured and inspected according to national standard GB/T5836.2-2006.

2. Product Color

Our company’s PVC-U building drainage pipes and fittings are white.

Product Advantages:

◆ Corrosion-resistant and Insect-proof
Lightweight, easy and quick to handle and install, significantly accelerating project progress and reducing construction costs. Suitable for indoor drainage, continuous discharge of domestic water at <40℃, and instantaneous drainage temperature at <90℃.

◆ Superior Chemical Resistance
Excellent resistance to acids, alkalis, and corrosion, making it ideal for chemical industry applications. Good resistance to external pressure, impact, and tensile strength, suitable for piping projects under various conditions.

◆ Larger and Thicker, Longer Service Life
Using food-grade, environmentally friendly materials, using up to 35% more material than ordinary pipe fittings, providing an extra layer of safety! Good aging resistance; according to pilot data from the Ministry of Construction, the service life is 30-50 years, making it an ideal material for building drainage and sewage.

◆ Low Resistance, Non-conductive, High Flow Rate
The material is non-conductive and unaffected by electrolysis or current corrosion. The smooth inner wall minimizes fluid flow loss, and dirt does not easily adhere to the smooth pipe wall, making maintenance simple and inexpensive.

◆ Easy Installation and Low Cost
Cutting and connection are both simple. Pipe and fitting connections use reliable and safe PVC glue, making construction simple, convenient, and highly efficient.

◆ Low Thermal Conductivity and Excellent Watertightness
The pipe has a low coefficient of linear expansion of 0.07 mm/℃, resulting in minimal deformation due to temperature changes. Its low thermal conductivity and modulus of elasticity provide superior freeze resistance compared to cast iron drainage pipes. Whether using adhesive bonding or rubber ring connections, installation maintains excellent watertightness.
