CDI, one of the world’s leaders in pipeline pig detection, recording and locating technology, broke ground recently for its expansion project in Broken Arrow, OK.
According to market studies, all indications are that the importance of the shale gas market is not going to diminish in the foreseeable future. On the contrary, significant growth is projected in many quarters. For example, a 2011 report issued by ICF International on behalf of the INGAA Foundation predicted that total United States and Canada shale gas production will jump from 2010 levels of about 13 Bcf/d to 52 bcf/d by the year 2035.
A pig trap must be designed to match the pipeline section design specifications. The mechanical design characteristics of the pig trap should meet or exceed the design pressure, have the same design factor, have compatible material type, be designed using the same design code and be suitable for the same temperature range as the pipeline section that it serves.
An intelligent inline inspection run including XYZ mapping provides valuable input in various assessment methodologies and the automated integration of the accurate pipeline centerline with its physical properties into a central pipeline integrity management software allows for a cost-effective and time-saving enhancement of the accuracy and reliability of the assessments results.
Being subject to appropriate inspections, pipelines and piping/pipework offer an almost unlimited service life. Strength and actual service capabilities must be assessed at regular intervals. Especially for thin-walled pipes made of high-strength steel, it is of particular importance to conduct regular inspections and examinations to detect any flaws and defects before they actually start to cause problems. Here, ultrasonic and magnetic flux leakage (MFL) pigs have been established as proven and suitable tools for inspection applications.
Full deployment and inspection of unpiggable pipelines has been achieved with Explorer II. Explorer II is an untethered, modular, remotely controllable, self-powered inspection robot for the visual and non-destructive inspection of 6- and 8-inch natural gas tranmission and distribution system pipelines.
