Flexible, Tough, Reliable…
Varying pipeline wall thickness is a major consideration when planning a pigging program and requires a pig that is strong enough to withstand the internal environment, yet flexible enough to traverse the various line sizes without loosing seal. To meet this challenge Inline developed the Uni Pig Series for applications where flexibility is a must. The Uni-Cup Pig® , Uni-Flex Pig® Uni-Flex Pig® 2C and Uni-Plus Pig® pigs are solid cast from our MAXITHANE® urethane and have unique design characteristics to address different application needs and are available in a variety of sizes. Wrap brushes can be added to each style for more aggressive cleaning. Our Uni pigs are the go-to for liquid removal, product separation and evacuation.
Uni-Pig Models:
The Uni-Cup Pig™ is manufactured as a single piece construction with no small parts. Three cups are molded along the body providing a good flexible seal. This style pig is used where more flexibility is required such as pipeline with varying wall thickness, low flow, or low pressure applications.
This pig is made of Inline’s MAXITHANE™, a higher performing polyurethane. Various durometers are also available to meet specific job requirements.
The Uni-Plus™ Pig combines sealing and scraping capabilities in one cleaning pig. Its solid one piece construction and unique cup ,disc design provides the best possible combination for cleaning efficiency. The cup shape allows the pig to run long distances while maintaining a good seal, even through parts of the pipeline that are out of round. The discs provide the most effective design to remove or scrape foreign material from the pipe walls.
Where hardened deposits are encountered the Uni Plus™ Pig is available with circular stell scraping brushes. The brushes are made of tempered steel to remove hardened deposits.
The solid polyurethane Uni-Flex™ Pig is cast as a single piece construction. The flexible combination of discs and a single cup creates an effective pig for removing liquids from wet gas systems, water from product pipelines, and paraffin from the walls of crude oil pipelines.
Manufactured from MAXITHANE™, Inline’s high performance polyurethane, this pig can flex through varying diameter pipelines, short radius weld ells, tees, valves, dents and out-of-round pipe. Its hollow core allows the pig to expand in diameter thereby increasing its seal as the differential pressure across the pig increases and to center itself for even wear.
The Uni-Flex™ 2C is a solid polyurethane pig cast as a single piece construction. The flexible combination of cups and discs creates an effective pig for removing liquids from wet gas systems, water from product pipelines, and paraffin from the walls of crude oil pipelines.
Manufactured from Inline’s MAXITHANE™, high performance polyurethane, it flexes through varying diameter pipelines, short-radius weld ells, tees, valves, dents and out-of-round pipe. Its hollow core allows the pig to expand in diameter thereby increasing its seal as the differential pressure across the pig increases and to center itself for even wear.
