Inline inspection of the "unpiggable" in fired-heaters and pipelines
Page last modified
Thursday, December 3, 2020 - 13:59
The MERLIN inline inspection tool takes up to 50’000 wall thickness and internal radius readings per metre allowing for identification of tube defects, including: diametric growth; internal and external corrosion; local and general metal loss; pitting and internal fouling.
The bi-directional, single body, neutrally buoyant construction allows the pig to travel with fluid flow for maximum manoeuvrability.
Using the data obtained during the inspection process, Cokebusters can provide Level 1 & 2 FFS/RLA on request.
Pro/con
Single body (able to navigate plug headers)
Able to inspect furnace designs that incorporate common headers
RF A-scan recorded for every measurement
Superior data coverage compared to traditional (grid) UT
Time efficient and cost effective (compared to standard UT and furnace downtime for alternative methods)
Quick deployment ( no shipping of inspection equipment – all hand carry)
Only currently available between 2.5” ID and 12” ID
Specification
Applicability
Fired heater configurations containing 1D | short-radius return bends | plug headers mule-ears flat-back bends Fired heaters containing multiple tube diameters throughout the process coil Arbour coils, Convection coils containing finned/studded tubing
Areas of Application
Process piping within fired heaters | HRSG/OTSG boilers | “unpiggable” pipelines up to 12-inch diameter | Transfer lines | Slop/wastewater lines
Capabilities
Detects localised metal loss | Detects pitting | Detects creep damage (bulging, ovality, swelling) | Able to model true corrosion patterns
Certifications / licences
Patented design
Collaboration
Cokebusters MERLIN inline inspection is available as part of Cokebusters combined decoking and inspection service or stand-alone using a third-party decoking provider.
Compliance
Calibrated to recognised standards.
Inspection
Data analysis is carried out by fully qualified inspection technicians throughout the on-site inspection process.
System Requirements
Requires no Technicians to access the inside of a heater | Usually requires no scaffolding within the radiant box | Requires no surface preparation (grinding) prior to measurement
