Turbine Pedestal Bearings - Sealing Oil Joints with Marston Universal Jointing Compound

Aug. 18, 2011 - PRLog -- How does Marston Jointing Compound work ? Free samples are also available for your trials !

An essential component in steam and gas turbine power plants are the turbine pedestal bearings.These oil lubricated plain bearings support the entire weight of turbine journal bearings, the turbine shaft and blade assembly (the rotor) and the turbine shell. The turbine pedestal bearing’s function is to allow for thermal expansion, permitting the turbine shell to easily slide and follow the turbine rotor as the turbine assembly expands and contracts. With steam temperature exceeding 1000 degrees F, this expansion can be more than 1/2 inch; both axially and radially.

Marston is developed for application in the pedestal bearing flanges. It is resistant against mineral oils and synthetic oils, fuels, additives, gases, water, anti-freeze, etc. With a unique curtaining action, when pedestal bearing flanges sealed with Marston expand, Marston stretches, and then breaks cohesively, leaving sealant on both sides. When the flanges return together, the putty reseals, a self-healing mechanism. This makes Marston a particularly effective sealant on close fitting large flanges which are subject to extreme vibration, distortion, or joint movement, because while the seal may break for a microsecond, it reseals and the pedestal bearing fluids remain contained avoiding any leakage from the flange avoiding the risk of a fire.

With a higher temperature resistance and better bonding properties than other oil resistant sealing compounds, this product is formulated to avoid corrosion on any metals, and resist mineral as well as synthetic fluids used for oil circulation systems.The non-hardening property allows for several assembly and disassembly without reapplication. For this, its unique red color allows for easy identification on the flange surfaces.

When used in conjunction with old used gaskets as a gasket dressing material, it can supplement the sealing effect and avoid the downtime associated with the lead times of waiting for a replacement gasket. All threaded joints can be sealed against leakages with the application of Marston. The drops of oil that normally leaks from the shopfloor machines that can cause slips and falls is 100% sealed with Marston on threads. These threaded joints can be easily opened as well unlike in case of other thread sealing compounds that work on the basis of creating a rigid sealing material to stop oil leakage but need a higher torque to break open sometime damaging the threads. Marston  is non-hardening in nature so while it seals the threads it also allows for easy opening for maintenance.

With every box of 10 tubes Marston 80ml, you get a Marston Cleaner absolutely free so you do not need to look around for a cleaner to clean the surfaces before sealing. Just apply the cleaner, let dry for a minute and apply Marston. With its non-hardening characteristics you get unlimited assembly time when required.
