Rotational Lining Solutions

rotolining

Rotational lining (aka rotolining) is a technology which allows us to bond a uniform, seamless polymer layer to the interior of virtually any metallic structure, regardless of shape and complexity. In the rotolining process, granular resin is placed inside the structure to be lined and all openings are covered. The structure is heated while simultaneously being rotated about two axis. The resin melts and flows evenly over the entire inner surface of the structure, bonding to the metal substrate. Once cooled, the result is a monolithic corrosion and chemical resistant lining that conforms to complex shapes and 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, depending on the size and service of the part. Standard raised face weld neck (RFWM) flanges, or United’s proprietary Welded Connection may be integrated into the lined fitting allowing for installation in either a 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. Or breadth of size and manufacturing capabilities can accommodate most size requirements.

Maximum dimensions for rotolined structures:

  • 8ft in diameter x 20ft length
  • 10ft in 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 applications provides a permanent solution to the corrosion and abrasion challenges of the oil and 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
