HVAC Piping & Fitting Solutions

Copper Refrigerant Piping

Heavy-gauge hard and soft copper tubing brazed with nitrogen purging for zero oxidation and leak integrity.

Suction & Liquid Line Piping

Engineered dual suction and liquid lines with calculated oil traps and vibration dampers for optimal flow.

Drain / Condensate Piping

Rigid uPVC and CPVC gravity drainage with engineered slope gradients and water seal traps to avoid leaks.

Chilled Water Piping

Seamless Schedule 40 MS/ERW carbon steel headers and branch lines hydro-tested to 1.5x working pressure.

Pipe Insulation

Closed-cell elastomeric nitrile rubber and XLPE thermal insulation engineered to eliminate condensation.

Supports & Hangers

Heavy-gauge GI channel supports, threaded drop rods, seismic bracing, and vibration isolation clamps.

Valves & Fittings

Cast iron and brass balancing valves, butterfly valves, Y-strainers, and check valves for hydronic balance.

Related Piping Works

Riser sleeve sealing, firestop penetrations, pressure gauge tapping, and directional flow labeling.

Field Engineering & Quality Assurance

Piping Execution & Testing Standards

01

Nitrogen Purged Brazing

Continuous nitrogen flushing during silver brazing to prevent internal carbon scaling and protect inverter valves.

02

High-Pressure Hold Testing

Nitrogen pressure holding up to 550 PSI for 24-48 hours to guarantee 100% leak integrity prior to charging.

03

Deep Vacuum Dehydration

Double-stage rotary vacuum evacuation down to 500 microns ensuring total non-condensable and moisture removal.

04

Thermal Expansion Control

Strategically placed expansion loops, flexible bellows, and guide anchors preventing pipe thermal stress fatigue.

05

Vapour-Barrier Sealing

Continuous adhesive joint gluing and vapor barrier sealing with zero thermal bridging to avoid sweating.

06

Flow Direction & Identification

Color-coded CPWD and ASHRAE compliant directional banding and service labeling across all headers and risers.
