Ruisong SCH40 Industrial UPVC: The Versatile Choice for Modern Infrastructure

As a leading manufacturer, Ruisong provides high-grade Schedule 40 (SCH40) UPVC piping designed for diverse industrial, municipal, and residential applications. Known for its high impact strength and ease of installation, our SCH40 PVC pipes are the industry standard for systems where high pressure or high temperature is not the primary concern, but durability and cost-savings are essential.

Key Technical Specifications

• Material: Unplasticized Polyvinyl Chloride (Rigid UPVC)

• Manufacturing Standard: ASTM D1785 / ASTM D1784

• Dimensions: IPS (Iron Pipe Size) – Schedule 40 Wall Thickness

• Size Range: 1/2″ up to 24″ (Nominal Pipe Size)

• Pressure Rating: Varies by size (Designed for moderate pressure applications)

• Max Temperature: 140°F (60°C)

• Color: Standard White (Custom colors available for industrial identification)

• Connection: Solvent Cement (Cold Welding) or Threaded (Fittings only recommended)

Why Professionals Choose Ruisong SCH40 UPVC?

1. High Flow Efficiency:
With a smooth, non-porous interior surface, our SCH40 pipes minimize friction loss and prevent the buildup of sediment or biofilm, ensuring consistent water pressure over decades of use.
2. Chemical & Corrosion Resistance:
Resistant to a wide array of acids, bases, and salts found in soil and industrial effluents. It will never rust or pit, unlike traditional metallic piping.
3. Lightweight & Fast Installation:
The rigid yet lightweight nature of UPVC makes handling and installation significantly easier and cheaper than steel or ductile iron, requiring no specialized heavy machinery for jointing.

Primary Applications

• Potable Water Supply: Safe, non-toxic transport for residential and commercial water mains.

• Irrigation Systems: Large-scale agricultural and landscape water distribution.

• Pool & Spa Infrastructure: Resistant to chlorine and common pool chemicals.

• Wastewater & Drainage: Ideal for sanitary sewer and storm-water systems.

Product Selection Matrix: Find Your Perfect Pipe

• Need more pressure? Upgrade to our [Schedule 80 聚氯乙烯] for thicker walls and higher PSI ratings.

• Handling Hot Water (up to 200°F)? You must switch to our [SCH40/80 CPVC Pipes].

• Working with Metric/European Standards? See our [DIN Standard UPVC Pipes].

Frequently Asked Questions

Q1: What is the difference between SCH40 PVC and UPVC?
A: “聚氯乙烯” stands for Unplasticized PVC, which means it is rigid and does not contain added plasticizers. In the United States, “SCH40 PVC” almost always refers to UPVC. Ruisong SCH40 UPVC is the rigid, high-strength material required for industrial and water supply piping.

Q2: Can SCH40 UPVC be used for hot water?
A: 不. SCH40 UPVC is rated for a maximum temperature of 140°F (60°C). For hot water applications (up to 200°F), we strongly recommend using our 聚氯乙烯 (Chlorinated Polyvinyl Chloride) piping systems.

Q3: Is Ruisong SCH40 PVC pipe UV resistant?
A: Our SCH40 pipes contain titanium dioxide (TiO2) to help protect against UV degradation. However, for permanent outdoor installations in extreme sunlight, we recommend painting the pipe with a light-colored water-based latex paint to maintain long-term impact strength.

Q4: Can I use Schedule 40 PVC for compressed air lines?
A: 不. Ruisongbuild, following industry safety standards, does NOT recommend using any thermoplastic pipe (PVC, 聚氯乙烯, or CPVC) for compressed air or gas transport. These materials can fail in a brittle manner under gas pressure. Use our PE pipes for specific gas applications where rated.

Q5: Is SCH40 pipe thinner than SCH80?
A: Yes. Schedule 40 has a thinner wall and a larger internal diameter (ID) compared to Schedule 80 of the same nominal size. This makes it more cost-effective and provides better flow for gravity-fed or low-pressure systems.
