PVC pipes are categorized by “schedules,” which refer to the thickness of their walls. LESSO America manufactures various types, with PVC SCH 40 pipe being one of the most commonly used. Each schedule is designed to handle specific pressure ratings and installation environments, making it important for contractors to understand the distinctions.

PVC SCH 40 Pipe: A Standard in Many Projects
PVC SCH 40 pipe is known for its balance between strength and cost-efficiency. It is often used in residential plumbing, irrigation, and drainage systems. LESSO America offers PVC SCH 40 pipe in a variety of diameters, allowing for flexible design across different project types. Its smooth interior promotes efficient water flow, and its corrosion-resistant surface makes it suitable for long-term use in both above-ground and underground settings.
How SCH 40 Compares to SCH 80 and Other Options
Compared to SCH 80, PVC SCH 40 pipe has thinner walls and a lower pressure rating. SCH 80 is often chosen for industrial applications where higher pressure handling is required. However, SCH 40 is typically more affordable and easier to install, making it ideal for residential and light commercial construction. LESSO America also produces SCH 80 and other pipe types, providing customers with options based on specific system requirements.
When comparing SCH 40 to SDR (Standard Dimension Ratio) pipes, another difference is that SCH pipes are based on fixed wall thickness, while SDR pipes vary wall thickness based on pipe diameter. This makes PVC SCH 40 pipe a more predictable choice for installations where uniform strength is preferred.
Conclusion
PVC SCH 40 pipe continues to be a practical solution for many construction and plumbing applications due to its cost-effectiveness and durability. While other schedules like SCH 80 offer higher pressure ratings, LESSO America’s SCH 40 pipe meets the needs of most residential and light commercial projects. Their product line helps contractors choose the right pipe for the job without compromising on performance or budget.
