in the s-lay system, the pipeline assembly is done at the installation site, on board a vessel that has all the equipment required for joining the pipe segments: pipe handling conveyors, welding stations, x-ray equipment, joint-coating module, etc. the s notation refers to
this method is very time-consuming and thus very costly since it involves cutting the belt, dismantling it from the press, turning the belt and re-installing it in the press followed by the belt joining operations welding and grinding of the joint and running-in procedures.
automated conveyor roller condition monitoring is an emerging field that has risen out of the need to make bulk handling conveyors more reliable. belt conveyor systems are widely utilized for continuous transport of dry bulk materials i.e. coal , iron ore over varying distances.
a joiner is an artisan and tradesperson who builds things by joining pieces of wood, particularly lighter and more ornamental work than that done by a carpenter, including furniture and the 'fittings' of a house, ship, etc. joiners may work in a workshop, because the formation of various joints is made easier by the use of non-portable, powered machinery, or on job site.
a surface lift is a means of cable transport for snow sports in which skiers and snowboarders remain on the ground as they are pulled uphill. once prevalent, they have been overtaken in popularity by higher-capacity aerial lifts like chairlifts and the gondola lift.today, surface lifts are most often found on beginner slopes and very small ski areas. they are often utilized at glacier skiing .
however, this type of drum motor design has a limited maximum radial load due to the bending stresses caused by the normal belt tension of a conveyor and is therefore used mainly for small light duty conveyors and loads. for heavier loads the most common design is to use two separate shafts, one fixed to the motor housing and one fixed to the .
