40 North American Oil & Gas Pipelines | JUNE 2 018 T.D. WILLIAMSON PITBOSS PIGS (918) 447-5000 • Corrosion can't be covered up — literally or figuraƟvely. According to the NaƟonal Asso- ciaƟon of Corrosion Engineers (NACE), it costs the pipeline industry more than $1 billion an- nually. It's a threat that's impossible — and risky — to ignore. Removing pipeline debris with cleaning pigs is a first line of defense in corrosion control. But even the best-orchestrated pigging program can leave deposits in pipeline pits. When con- taminants like paraffin, asphaltene or mineral scale remain behind, they can cover up acƟve corrosion. Masking the problem not only al- lows it to worsen, it prevents corrosion inhibi- tors from reaching their target. One of the most aggressive cleaning pigs on the market, the PitBoss pig from T.D. William- son, is designed to get to the boƩom of pipe- line pits, removing soŌ to hard deposits and scale with its powerful wire brushes. Each brush acts independently as both a spring and a scraper, forcing itself into piƩed areas and scouring away corrosive debris from the inter- nal diameter, regardless of wall thickness or ovality. That leaves the pipe wall more recep- Ɵve to internal corrosion inhibitors, addressing the threat right where it starts. When coupled with RealSeal urethane cups with mulƟ-lip sealing grooves — which per- form like mulƟple scraper discs — the PitBoss is even more effecƟve, providing extremely thorough results. Available for pipeline diameters of 6 in. and larger, as well as in dual diameter configura- Ɵons, PitBoss pigs help operators avoid masked corrosion throughout their pipeline systems. HEBNA CORP. IMFL TOOLS • The HEBNA iMFL tools have the unique capability to inspect steel (or any ferrous host pipe) through an internal lining. MagneƟc flux leakage (MFL) tools used for the inspecƟon of steel pipes have been in use for decades and are a highly accurate method to detect metal loss due to corrosion or pipeline damage. A limitaƟon in the applicaƟon of MFL tools has been their inability to inspect steel pipelines with an internal lining be- cause the tool's array of magnets must be touching or be in close proximity to the pipe wall to obtain an accurate read- ing. AŌer years of research and development, HEBNA iMFL Services Inc. has introduced iMFL, a series of magneƟc flux leakage tools which can inspect steel pipelines through any non-ferrous liner material (cement, polyethylene, cured-in- place pipe, etc.) in high definiƟon delivering results equal to or exceeding the results of standard MFL inspecƟon of unlined pipe.
