Smartpigging

Inline inspection of the "unpiggable" in fired-heaters and pipelines

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
