PIPEWORK & INSULATION

Protect the connections that matter.

Pipework repairs, valves and insulation for reliable chilled-water and condenser-water distribution.

01 / UNDERSTAND THE SYSTEM

Pipework & insulation in context.

Pipework carries cooling around the building. Correct insulation and a continuous vapour barrier help reduce heat gain and condensation on chilled-water systems.

Well-planned pipe repairs consider the joint, valve, insulation and reinstatement—not only the leaking section.

Pipes & fittings

Material, diameter, supports, connections and operating conditions determine the repair approach.

Valves & accessories

Isolation, balancing and control valves perform different functions and need correct selection.

Insulation & cladding

Insulation limits heat gain; a continuous vapour barrier helps prevent moisture reaching cold surfaces.

02 / SCOPE & CONDITION

What we look at.

Area	What matters	Why it matters
External condensation	Insulation condition and vapour-barrier continuity	Wet insulation may need replacement, not simply another outer covering.
Valve replacement	Size, duty, pressure rating and flange arrangement	Verify dimensions and access before procurement.
Leaking joints	Joint type and sealing condition	Allow for isolation, drainage and reinstatement in the scope.

Work that can be included

Leak rectification and pipe replacement
Isolation and balancing valve replacement
Flanges, fittings and jointing materials
Insulation and protective cladding repairs

Define the scope before work starts.

Parts, quantities, access, shutdowns and reinstatement are confirmed against your site and equipment. Additional defects or specialist works are discussed separately.

03 / HOW THE WORK PROGRESSES

A clear route from enquiry to completion.

01
Measure & assess
Confirm the actual pipe, valve and connection dimensions.
02
Plan isolation
Coordinate water drainage, access and shutdown timing.
03
Repair & reinstate
Complete pipe or valve works and insulation reinstatement.
04
Check the system
Inspect leakage and restore the agreed operating arrangement.

04 / COMMON QUESTIONS

A little more clarity.

Why is my chilled-water pipe sweating?

Condensation can occur when a cold surface meets humid air. Damaged insulation, gaps in the vapour barrier or wet insulation should be assessed before repair.

Can I identify pipe diameter from the insulated outside size?

Not reliably. Insulation and cladding add thickness. Confirm the bare pipe dimensions or equipment documentation.

Is GI cladding the vapour barrier?

Cladding protects the insulation mechanically, but the full insulation system and sealed vapour barrier need to be considered. Metal covering alone is not enough.
