Scott McDonald, Senior HDPE & Frac Specialist, Victaulic, reveals how a lightweight launcher can simplify the pigging process for layflat hose frac lines. Pigging lines for maintenance and flow assurance is a necessary exercise and a practical way to reduce the risk of line failure. But, it can be time consuming and costly when using conventional equipment. The pigging process facilitates line integrity management, allowing buildup and blockages caused by scale, paraffin, asphaltenes, iron oxides and gas hydrates to be reduced to alleviate their impact on production. It also enables corroded areas to be identified and addressed before damage escalates to a point that safety could be jeopardised.
