The Dura-Cup pig combines the advantage of standard cup mandrel pig with the flexibility of a cast urethane pig. Its one-piece construction does not require redressing. The pig is hollow which allows for expansion and better sealing against the pipe wall.
The Dura-Cup pig is used where more flexibility is required such a pipeline with varying wall thickness, low flow or low pressure applications. It is very effective in removing liquids from wet gas systems, water from product lines, product separation and product evacuation. It is good for controlling paraffin in crude oil pipelines.
The Dura-Cup pig is available in standard and high performance polyurethane. It is available with pull ropes, cables and nylon straps. Brushes can be added for more aggressive cleaning. |
