Rotational Lining Solutions
Rotational lining (aka rotolining) is a technology which allows us tobond a uniform, seamless polymer layer to the interior of virtuallyany metallic structure, regardless of shape and complexity. In therotolining process, granular resin is placed inside the structureto be lined and all openings are covered. The structure is heatedwhile simultaneously being rotated about two axis. The resin meltsand flows evenly over the entire inner surface of the structure,bonding to the metal substrate. Once cooled, the result is amonolithic corrosion and chemical resistant lining that conformsto complex shapes and is virtually free of stresses.
Wall thicknesses can range from 0.090 inches to 0.450 inches,but typically range from 0.250 inches to 0.400 inches, dependingon the size and service of the part. Standard raised face weld neck(RFWM) flanges or United’s proprietary Welded Connection maybe integrated into the lined fitting allowing for installation in eithera mechanical or fully welded system.
We line a wide range of chemical processing, transfer and storage equipment, including some the largest pipe and vessels in the industry. Our breadth of size and manufacturing capabilities can accommodate most size requirements.
Maximum dimensions for rotolined structures:
- 8ft diameter x 20ft length
- 10ft diameter x 12ft length
Our state-of-the-art technology uses different high performance thermoplastics to internally protect steel structures, such as:
- Manifolds and well heads
- Tees
- Bends and reducers
Thousands of rotational lining solutions have been installed over the last 30 years, and many are still in service today. This application provides a permanent solution to the corrosion and abrasion challenges of the oil & gas, mining and industrial processing industries.
United Pipeline Systems can cover a wide range of fluid requirements, temperatures and applications through the use of high performance thermoplastics such as:
- High-density polyethylene (HDPE)
- Nylon PA-12
- PVDF
