Case Study: Main Aqueduct Reinforcement

Location

Mining Company (Aqueduct Line from Extraction Wells)

Application Area

22” Water Transport Duct – Main Aqueduct Line

Project Overview

After a rupture occurred on a critical 22” aqueduct transporting water to the plant, the client performed an initial welded patch. To ensure lasting protection and reinforcement, UPS composite wrap technology was deployed over the repair site.

Challenges Faced

Large diameter pipeline carrying essential process water

Underground pipe section required excavation

Need to reinforce an in-situ welded repair

Repair needed to remain in service during application

Objectives

Strengthen the welded repair on the main aqueduct

Avoid shutdown of water transport system

Apply a long-lasting composite wrap in field conditions

Reinforce pipe integrity with minimal disruption

Repair Solution & Process

Products Used

UPS ASME EMERGENCY PIPE REPAIR BANDAGE

Application Steps

Excavation & Access

Soil was removed to expose the damaged duct with approx. 10 cm clearance below for access and application.

Bandage Activation

Each UPS THISTLEBOND EMERGENCY PIPE REPAIR BANDAGE was submerged in water for 20 seconds to trigger curing.

Reinforcement Wrapping

The activated tape was applied in multiple overlapping layers across the welded area.

Layering for Strength

100 wraps were used to achieve a 14 mm reinforced layer across 1.2 meters of pipe length.

Cure & Backfilling

The wrap was allowed to cure overnight before backfilling, ensuring full mechanical strength.

Results & Key Benefits

Robust reinforcement applied while line remained in operation | Superior mechanical strength over existing welded area | Minimal disruption to the water supply system | Simple yet high-performing repair using no heavy tools or welding | Avoided major replacement works and operational shutdown

SUMMARY

This case highlights how UPS composite wraps provide not just emergency sealing, but long-term structural reinforcement — protecting essential infrastructure with proven reliability in the field.
