Product Overview
Chilled Water Piping Systems are the essential distribution network for transporting chilled water from central cooling sources - such as water-cooled or air-cooled chillers - to air handling units (AHUs), fan coil units (FCUs), and other terminal cooling equipment throughout a building. These piping systems form the backbone of any central air conditioning system, ensuring that chilled water is delivered efficiently and reliably to maintain comfortable indoor environments in commercial, industrial, and residential buildings.
Chilled water supply temperatures typically range from 4°C to 13°C, and the piping network must be designed to handle these temperatures while preventing condensation, corrosion, and heat gain. Our chilled water piping systems are available in a variety of materials and configurations to suit diverse project requirements, from small commercial buildings to large-scale district cooling networks.
Common Pipe Material Types
Depending on system pressure, temperature, installation environment, and budget, we offer a wide range of pipe materials for chilled water applications:
Galvanized Steel Pipe
Steel pipe with a zinc-coated protective layer that provides excellent corrosion resistance. Suitable for chilled water applications where resistance to condensation and corrosion is critical. Commonly used for surface-mounted pipes with threaded connections for diameters up to DN100. Widely used in HVAC installations for chilled water, condensate drainage, and cooling water systems.
Seamless Steel Pipe
Manufactured without weld seams, offering superior strength and reliability. Ideal for high-pressure chilled water lines in large commercial buildings and industrial facilities. Seamless steel pipes can withstand temperature fluctuations and pressure variations, ensuring safety and stability in demanding mechanical environments. Commonly used for chilled water lines, steam pipelines, and refrigerant transmission.
Welded Steel Pipe (ERW)
Electric Resistance Welded steel pipe, available in black steel (plain) or galvanized finishes. Schedule 40 black steel piping is commonly used for HVAC services including chilled water, process cooling, hot water, and condensate drainage. Stainless steel welded pipes are also available for applications requiring enhanced corrosion resistance in chilled water systems.
Composite Pipe (Multilayer Pipes)
Engineered with multiple layers, typically including an inner and outer layer of polyethylene (PE-RT or PE-X) with a flexible butt-welded aluminum core. Ideal for chilled water applications where flexibility, corrosion resistance, and ease of installation are priorities. Pre-insulated composite piping systems are also available for district cooling and chilled water applications, offering superior thermal performance and reduced installation times.

Selection Considerations
Selecting the right chilled water piping system requires careful evaluation of project-specific parameters, including:
System Pressure
Determines the required pipe schedule and material grade.
Temperature Range
Affects material selection and insulation requirements.
Water Quality
Influences the choice between galvanized, black steel, stainless steel, or composite materials.
Installation Environment
Indoor vs. outdoor, exposure to corrosive elements, and space constraints.
Connection Method
Threaded, welded, flanged, or grooved connections based on pipe diameter and site conditions.
Budget & Lifecycle Cost
Balancing initial material cost against long-term maintenance and replacement costs.
