Low Pressure Pipe: Global Market, Suppliers, and Procurement Guide

Introduction to Low Pressure Pipes

Low pressure pipes are designed to transport fluids and gases under relatively low operating pressures, typically ranging from 0 to 10 bar (0-150 psi). These pipes are widely used in water supply systems, irrigation networks, drainage, chemical processing, and HVAC applications. المواد commonly used include PVC, HDPE, ductile iron, steel, and concrete. Unlike high-pressure pipes, low pressure variants prioritize cost-efficiency and corrosion resistance over extreme mechanical strength. The global market for low pressure pipes is driven by urbanization, infrastructure development, and agricultural expansion, with a projected CAGR of 5.2% from 2023 to 2030.
