Cleaning Pigs

PEAS Cleaning Pigs are designed for use in the pre-commission and onstream cleaning of pipelines, transporting crude oil, refined products, lube oil, petro chemicals and natural gas, for which purpose several brush/cup combinations are mounted on a welded steel body.

On models CLE.1 up to CLE.8 a stiff body is used, on models FL.C.1 up to FL.C.4/1 two welded steel body sections are linked by means of a joint coupling inside a coil spring (exception: FL.C.2, which model has a very stiff coil spring as body).

Flexible means better sealing in bends.

All carbon components are coated for resistance against corrosion and chemicals.

Pigs will pass all round, full opening gate and plug valves, modern check valves and tees with full diameter branch at 90 or 45 to pipeline; guide bars recommended across opening when branch is 75% of pipe i.d. Pigs equipped with PEAS wear resisting polyurethane cups, type PU.C.1 (4"-14") or PU.C.2 (16"^). A partial flow by-pass facility through body of pig (including threaded bypass plugs), optional to prevent piling up of loosened material.

Pigs can also be equipped with polyurethane guards to prevent metal to metal contact. For this purpose steel or stainless steel brushes are replaced by perlon brushes and the spring mounted brushes are replaced by polyurethane blades.

On request some pigs can be modified to be used in Itag Pic valves.
