UPVC Drainage Pipe

I Product Introduction

UPVC drainage pipes are manufactured primarily from polyvinyl chloride (PVC) resin through an extrusion molding process, representing a technologically mature building drainage material. This product boasts corrosion resistance and service life far superior to cast iron pipes, featuring a smooth inner wall that resists scaling and is lightweight for easy installation. Widely used in civil building wastewater/sewage drainage, roof rainwater disposal, and chemical drainage, it has become the preferred material for modern building drainage systems due to its reliable connection methods and excellent physical properties.

I Product Features

● Exceptional Corrosion Resistance: Excellent resistance to chemical media like acids and alkalis, non-rusting, fundamentally preventing leaks and contamination caused by pipe corrosion.

● Low Flow Resistance, High Water Conveyance Capacity: Smooth pipe wall with a roughness coefficient of only 0.009, over 30% lower than cast iron pipes, resisting scaling and bacterial growth, maintaining high flow rates long-term.

● Lightweight & High Strength, Easy Installation: Weight is only 1/6 of metal pipes, easy to handle, and improves construction efficiency. Uses socket adhesive bonding or rubber ring connections, which are simple and reliable.

● Excellent Physical & Mechanical Properties: Tensile yield strength ≥43MPa, Vicat softening temperature ≥79°C, ensuring long-term structural stability.

● Long Service Life: Under standard use conditions, service life can reach 50 years, significantly exceeding traditional cast iron pipes, offering notable comprehensive economic benefits.

I FAQ

1. How do UPVC drainage pipes address drainage noise issues?

Standard UPVC pipes indeed have slightly poorer sound insulation than cast iron pipes. Currently, noise reduction is mainly achieved in two ways: First, by using foam-core pipes, where the middle foam layer provides sound absorption. Second, by using internal spiral pipes, which guide water to flow in a spiral pattern, reducing noise by 5-18dB. For areas requiring quiet environments, these improved products are recommended.

2. What is the connection method for UPVC drainage pipes?

UPVC drainage pipes primarily use socket adhesive bonding, where specialized adhesive bonds the pipe and fitting into one unit. Key points for leak-proof connections: bonding surfaces must be clean and dry; adhesive must be applied evenly; sufficient curing time after insertion; and proper installation of expansion joints to handle thermal expansion/contraction as per standards.

3. What is your company's delivery time?

For standard stock products, shipment is typically within 7 working days. For bulk orders, production and shipment are usually completed within 15-25 working days, depending on quantity. Specific quotations and schedules can be customized based on your requirements.
