Leakage and emmission control is a critical function in process plant, industrial equipment, machinery, and transportation systems. This volume reflects many of the recent advances in sealing technology with topics including: tribology; static seals; and mechanical seals.
Part 1 Tribology: tribological behaviour of PTFE seal materials in sealing contact with steel and ceramic coatings; influence of the sealing surface characteristics on friction behaviour. Part 2 Dynamic seals - 1: the sealing mechanisms of rotary shaft seals with reference to the elastomer deformation in the contact zone; a study on the fluid-flow and the film-thickness of radial shaft seals using fluorescent microcapsule visualization and laser-induced fluorescent method; prediction of lip seal performance - an advanced FEA/interface iterative solver; material models for finite element analysis based on the example of rotary lip seals for pressure. Part 3 Modelling: gas pressure and leakage rate in static seals; cost-effective perfluoroelastomer sealing solutions for aggressive environments; increased confidence in sealing system design using FEA simulations; simulation of fluid seals by coupled fluid-solid-mechanical analysis. Part 4 Static seals: experience with bolted-flanged joints and the selection of gaskets to minimize fugitive emissions; fastener phobia in fluid sealing; an alternative to asbestos for high-temperature gasketting applications; the further development of a high-temperature sealing material based upon chemically exfoliated vermiculite; the use of serrated core metallic gaskets on air coolers. Part 5 Mechanical seals - 1: towards the universal mechanical seal for industrial pumps; development and application of double pulse gas-liquid face seals; condition monitoring of mechanical seals using actively generated ultrasonic waves; reactor coolant pump seal response to loss of cooling. Part 6 Dynamic seals - 2: optimal surface roughness of the shafts co-operating with oil lip seals; leakage of radial lip seals at large eccentricities; face packing seals - new opportunities for pump rotor hermetic sealing; study of sealing capability of magnetic fluid shaft seals. Part 7 Emissions: joint industry project on the measurement of fugitive emissions from valve stems; improved gland packings for control valves; fugitive emissions from VCM - PVC units - results of the ECVM survey; in-situ repair of double "O" ring seals on CO2 pressure boundaries. Part 8 Mechanical seals -2: the influence of the duty parameter G on the PV limit in mechancial seals; an advanced test bench for mechanical face seals testing; development and tests of the advance wear-resistant mechanical face seals; analysis of lubricant regime transition, experimentally observed in liquid face seals, using an analytical model for thermoelastic face distortion. Part 9 Non-contacting: a model of zero pressure differences and zero leakage for non-contacting spiral groove liquid face seals; determination of optimal parameters of labyrinth-screw seals and pumps; advanced aerostatic dry gas seal; influence of centrifugal growth of runner on floating bushing oil seal performance and compressor stability using finite element methods.
