Strainers, steam traps, Expansion bellows
Strainers
Y-Type
Strainers should be installed upstream to protect an installation from scales and dirt. The larger items fall to the bottom and are held in a basket for later disposal.
On demand, strainers can be made from cast or forged material. Vannes RIGAU strainers can be customized in order to match your process requirement (pressure drop calculation, filtration size, differential pressure monitoring).
Steam Traps
A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam. Most steam traps are nothing more than automatic valves. They open, close or modulate automatically. The three important functions of steam traps are:
- * Discharge condensate as soon as it is formed (unless it is desirable to use the sensible heat of the liquid condensate)
- * Have a negligible steam consumption (i.e. being energy efficient)
- * Have the capability of discharging air and other non-condensable gases.
Expansion bellows
In a piping system a Expansion joints alternately known as Bellows are like sealed springs. Sealed because it is required to contain the fluid pressure which is flowing through it and spring because it is required to respond to the movement of the connected piping without offering appreciable stiffness to the piping system.
An expansion joint/bellow element employed in a piping system is an assembly of generally more than one convolute in series. The convolutes are designed strong enough to withstand the internal pressure of the system, at the same time the typical contour of the convolute assembly allow sit to flex under thermal movement of the connected piping. As a result of this extreme flexibility the expansion joint / bellow as such is highly incapable of absorbing any longitudinal loads by its own,thereby requiring external attachments to transfer these longitudinal loads to its connected piping for maintaining the overall stability of the piping system under question.
