Half-Shell Sleeves for Offshore Riser Pipes, Pipeline Crossings, Flow Lines, and More
Mark Tool Half-Shell Sleeves are pre-molded SplashTRON® or ThermoTRON®, and are made to fit specific pipe diameters and in a range of thickness from ¾" to 4".
They are installed in the field over FBE coated pipe where extended continuous coverage is required.
Half-Shell sleeves are adhered to the pipe with specially formulated epoxy. Our Half-Shells sleeves are suitable for piping systems when it is not practical for piping to be sent to our plant for SplashTRON® or ThermoTRON® vulcanization.
Mark Tool has manufactured these Half-Shells sleeves for many years. We have extensive experience in producing Half-Shells sleeves in lengths up to 4m long.
Unlike our vulcanized plant, applied SplashTRON® and ThermoTRON® insulation, line pipe must be shipped to our plant for application. Instead, we can send this half-shell directly to the job site to be installed in the field by one of our recommended installers.
The applications would include but not be limited to:
