6-8 Flashcards
where is it best practice to locate a Steam Trap
on the lowest points in the system
what speed does steam flow at in a steam mainline
145 kilometres an hour
what is a steam separator
a series of baffles Force the steam to change Direction several times as it flows through the body of the separator
what is the purpose for the installation of a strainer and where should they be fitted
to catch nuts bolts and debris installed on their side on a steam main
what are branch Lines
branch lines are used to carry steam from the Steam mains to the point of use
what position is best practice to remove branch line from a steam main and why
taking from the top of the main is the best as it’s when it’s driest
what is the gradient of a condensate line
fall of 1 in 250
what is the reason for installing pressure reducing equipment
they’re fitted to maintain high pressure in a steam boiler
name two types of prv
Direct acting and pilot operated valves
safety valves r install where on a steam system
fitted to distribution systems
what is the purpose for installing vents and why
fitted to steam pipework and systems to remove air and other non condensate gas which may be present
when is water hammer produced
water hammer occurs when condensate build up in steam pipework and travels at velocities and collides with bands valves and other obstacles
give three examples of how to prevent water hammer
system should be warmed up slowly and by proper trained staff
systems should be designed to remove condensate as soon as practical after it forms
make sure to use appropriate steam traps and make sure they’re checked manually or automatically
list three methods for expansion in a steam system
expansion joints Loops or bellows
what precautions should be taken when installing anchors
the Anchor is adequately secured to the pipe.
the Anchor itself is structurally adequate. the Anchor fixings to the building structure or adequate.
