What is pipe 4″ SDR-41 gm upvc 4meter ?

 

Description

A 4″ SDR-41 GM UPVC pipe is a rigid, un plasticized polyvinyl chloride (UPVC) conduit designed for low-pressure or gravity-flow applications. “4”” denotes a nominal diameter of 4 inches (approximately 110 mm outer diameter), “SDR-41” indicates a Standard Dimension Ratio of 41 (where SDR = outer diameter / wall thickness)

Specifications pipe 4″ SDR-41 gm upvc 4meter

• Material: UPVC (ASTM D1784 compliant, with stabilizers for impact and UV resistance).
• Size: 4″ nominal (OD: 110 mm; ID: ~102 mm; varies slightly by standard).
• SDR Rating: SDR-41 (wall thickness ~2.7 mm; pressure rating ~6-10 bar for short-term use, but primarily for gravity flow).
• Length: Standard 6-12 meters per pipe section (custom lengths available).
• Color: Grey (GM designation for medium grade).
• Temperature Range: -5°C to 60°C (avoid freezing or extreme heat).
• Standards: Conforms to IS 4985 (India), BS EN 1452 (Europe), or ASTM D2241; local variants may include ISI marking for quality.
• Weight: Approximately 2-3 kg per meter, making it easy to handle.
• Certifications: Often ISI or equivalent certified; check for local plumbing codes compliance.

Usage

• Primary Applications: Gravity-fed systems like sewage drainage, rainwater harvesting, irrigation, and chemical effluent lines. Not for pressurized potable water due to SDR-41’s thin walls.
• Advantages: Resistant to rust, chemicals, and root intrusion; low friction loss for efficient flow. Cost-effective for large-scale projects in local markets.
• Limitations: Avoid high-pressure, hot water, or direct sunlight without protection. Not flexible for bending.
• Maintenance: Inspect for cracks or blockages; clean with rods if needed. In local contexts, it’s widely used in rural plumbing for affordability and durability in variable climates. Consult manufacturer specs or local plumbers for site-specific use.
