attention to pressure and temperature conditions. Poorly planned steam piping can create reliability problems, water hammer concerns, condensate return issues, maintenance access problems, and energy loss.

DePue supports steam and condensate piping work for boilers, heat exchangers, process equipment, humidification systems, washdown systems, heating systems, and production support utilities.

Steam work has to be coordinated around safety, pressure conditions, system isolation, hot work controls, testing, and startup. When project specifications require code welding, inspection, or documentation, the piping scope should be planned around those requirements before fabrication or installation begins.

For welding-related work, visit our boiler code welding page.

Compressed Air Piping

Compressed air is a critical utility in many industrial facilities. It may support production equipment, packaging lines, pneumatic controls, valves, tools, instrumentation, and plant operations. When air piping is undersized, leaking, poorly routed, or not properly supported, equipment performance can suffer.

DePue installs and modifies compressed air piping systems for active manufacturing and process facilities. Work may include compressor room piping, distribution headers, branch lines to equipment, drops to production areas, valve stations, air dryer or receiver connections, and prefabricated piping assemblies.

Compressed air piping should be planned around pressure demand, access for maintenance, condensate management where applicable, future equipment expansion, and the production areas being served.

Compressed air piping work may involve:

• Air compressor piping
• Main compressed air headers
• Branch piping to production equipment
• Equipment drops and isolation valves
• Receiver tank and dryer connections
• Rerouting or replacing leaking air lines
• Pipe support and vibration control
• Pressure testing and leak checks before startup

Chilled Water, Hot Water, and Glycol Piping

Heating and cooling utility piping supports production, process temperature control, building systems, air handlers, heat exchangers, chillers, boilers, pumps, and packaged mechanical equipment. When these systems are not routed or supported correctly, facilities can experience poor temperature control, pump alignment problems, leaks, restricted maintenance access, or startup delays.

DePue supports chilled water, hot water, and glycol piping for industrial and commercial mechanical systems. Work may include new installation, equipment replacement, piping modifications, tie-ins, prefabricated spools, pump connections, and system testing.

These systems often require coordination with HVAC equipment, process cooling loads, insulation, controls, commissioning, and shutdown windows.

For mechanical HVAC-related piping, visit our commercial HVAC contractor page.

Hydronic and thermal utility piping may include:

• Chilled water supply and return piping
• Hot water supply and return piping
• Glycol piping
• Boiler and chiller connections
• Pump suction and discharge piping
• Air handler and heat exchanger piping
• Expansion, support, and isolation valve coordination
• Flushing, pressure testing, and leak checks

Process Water, Plant Water, and Utility Water Piping

Many industrial facilities rely on utility water systems to support production equipment, washing, cooling, heating, cleaning, process support, and equipment protection. These systems often connect to pumps, tanks, heat exchangers, filters, skids, hose stations, and treatment equipment.

DePue supports process water and plant water piping for manufacturing, food and beverage, water treatment, and process facilities. Work may include piping replacement, reroutes, pump connections, equipment tie-ins, valve stations, utility headers, and prefabricated sections built before shutdown work begins.

The work must be planned around water demand, operating pressure, pipe routing, access, system isolation, drainage, and startup requirements.

Utility water piping may involve:

• Process water piping
• Plant water piping
• Non-potable utility water piping
• Pump discharge and suction piping
• Tank inlet and outlet connections
• Heat exchanger and skid connections
• Filtration or treatment equipment tie-ins
• Valve, drain, vent, and gauge installation
• Pressure testing, flushing, and leak checks

Utility Piping Equipment Tie-Ins

Utility piping projects often center on equipment connections. Boilers, chillers, compressors, pumps, heat exchangers, tanks, skids, air handlers, and process equipment all require piping that fits the equipment connections and the existing facility layout.

DePue supports equipment tie-ins that require careful field measurements, spool planning, flange orientation, valve access, support coordination, and installation sequencing.

Tie-ins are often where field conditions, equipment drawings, schedule pressure, and startup requirements come together. Proper planning reduces rework, outage risk, and field conflicts.

For equipment-related piping and fabrication, visit our pipe fabrication contractor page.

Utility equipment tie-ins may include:

• Boiler tie-ins
• Chiller tie-ins
• Air compressor connections
• Pump suction and discharge piping
• Heat exchanger piping
• Tank connections
• Process skid utility connections
• Air handler piping
• Utility branch piping to new production equipment
• Valve stations, bypasses, drains, vents, and isolation points

Prefabricated Utility Piping

Utility piping work often benefits from prefabrication. When pipe spools, valve stations, equipment connection assemblies, or rack sections are built before crews enter the field, installation can move faster and with less disruption.

DePue supports prefabricated utility piping assemblies for shutdowns, equipment replacements, mechanical room upgrades, pipe rack work, process support utilities, and GC-led construction projects.

Prefabrication is especially valuable when work must be completed during a weekend outage, night shift, holiday shutdown, or planned production stop.

For dedicated fabrication support, visit our pipe fabrication contractor page.

Prefabrication may include:

• Steam and condensate spools
• Compressed air piping assemblies
• Chilled water or glycol piping sections
• Pump connection piping
• Boiler and chiller connection spools
• Valve station assemblies
• Utility rack piping sections
• Shutdown-ready tie-in spools
• Replacement piping built before demolition begins

Shutdown and Tie-In Support for Utility Piping

Some utility piping work cannot be completed while systems are online. Steam headers, compressed air mains, process water lines, chilled water loops, fuel gas piping, and utility connections to production equipment may require planned shutdowns or carefully sequenced tie-ins.

DePue supports shutdown utility piping work by helping plan the scope before the outage begins. That includes field verification, material readiness, spool fabrication, isolation points, demolition sequencing, manpower planning, testing requirements, and startup coordination.

In shutdown work, the best outcome is safe isolation, accurate installation, tested piping, and utilities restored before production needs to restart.

For outage-driven work, visit our shutdown piping contractor page.

Shutdown utility piping may include:

• Replacing leaking or failing utility lines
• Installing prefabricated tie-in spools
• Connecting new equipment to existing utility headers
• Modifying steam, air, water, chilled water, hot water, glycol, or gas systems
• Installing bypass piping where required by the project
• Replacing valves, strainers, fittings, or support components
• Pressure testing and verifying the system before restart
