Products Description
Schedule 40 (SCH 40): This is a standardized wall thickness designation. Schedule 40 indicates a specific, medium-weight wall thickness that provides a excellent balance of strength, pressure handling, and cost-effectiveness. It is thicker and stronger than Schedule 10 but not as thick as Schedule 80.
Products Advantages
Durability: The combination of carbon steel construction and the zinc coating makes it extremely robust and resistant to physical impact and abrasion.
Corrosion Resistance: The zinc layer acts as a sacrificial anode, preventing the underlying steel from rusting. This makes it ideal for exposed applications.
High Pressure Rating: Schedule 40 wall thickness is designed to handle relatively high internal pressures for water, air, and other gases/liquids.
Long Service Life: With proper installation, it can last 50 years or more in many environments with minimal maintenance.
Ease of Installation: It is widely available with standard threaded ends (NPT - National Pipe Taper),
Products Specifications
Standard: ASTM A53 is the most common standard for galvanized steel pipe used in pressure and mechanical applications.
Grade: Usually Grade B, which has a higher tensile strength than Grade A.
Type: Type E (Electric Resistance Welded) or Type S (Seamless). ERW is more common and cost-effective for most applications.
Ends: Most commonly Threaded & Coupled (T&C), but can also be plain end (PE) for welding or grooving.
Products Applications
Schedule 40 galvanized pipe is a workhorse found in numerous industries:
Plumbing: Water supply lines (though declining in favor of copper/PEX for interior drinking water due to potential corrosion over time).
Gas Transport: For conveying natural gas and propane (check local codes, black pipe is often used for interior gas lines).
Structural & Construction: Handrails, scaffolding (though specific scaffolding pipe standards may apply), fence posts, framework, and protective bollards.
Industrial Uses: Compressed air lines, process piping, and as conduit for protecting electrical wires (where allowed by code).
Outdoor Applications: Irrigation systems, outdoor water lines, and flagpoles.
