There's a lot to understand about Flange, Gasket, Bolt & Nut, Spectacle Blind, Orifice Flange Description. We were able to provide you with some of the facts above, but there is still plenty more to write about in subsequent articles.

A car seal is a mechanical means of securing a valve in a certain operating position using a seal and a cable.  After a special locking key makes the seal, operation may be done only by means of cutting the cable.  Hence, it cannot be reused.  This is used for valves designated in the P&ID as “car-seal open” or “car-seal closed”.

Desuper heater is a device fitted with one or more spray nozzles, in which the quantity of spray nozzles depends upon the capacity.  These injects a fine spray of cooling water or feed water into a section of pipe where the superheated steam passed through, absorbing the heat from the steam and reduces the quantity of superheat.   To achieve the maximum mixing efficiency of steam and spray water, the direction of water injection is parallel to the steam flow.

Ejector is a device in which (a) a motive fluid flows from a region of high pressure through a nozzle into a low

pressure-mixing zone, developing a high velocity
(b) the motive fluid mixes with a load fluid entering the mixing zone, and (c) the mixture flows through a diffuser into a region at

a pressure higher than the load-fluid supply pressure.

Advantages:
* Large capacity ejector can be constructed because of simple structure and no moving parts.
* Maintenance free
* Corrosive gas can be treated because of wide range of material construction.
* Low initial cost

 Disadvantages:
* High operating cost
* Noise pollution in case of relieving directly to the atmosphere
* A large amount of waste water
* Narrow operating range

An insulated bolt and gasket is used to protect the pipeline from corrosion.  When dissimilar flange materials are

used in services with a suitable electrolyte and a conductive bolt and gasket, a galvanic cell may be set-up.  Thus, the flange

with the anodic metal (between the two) gets corroded.  Another use is isolate flange joints just before the pipe goes

underground by preventing the flow of electrostatic charge along the pipelines.  To prevent these situations, insulated bolts and

gaskets are used.

A steam trap serves as an automatic valve, which removes the hot condensate, a byproduct of the heat transfer between the steam and the fluid to be heated in a steam system.  The hot condensate is returned to the boiler to conserve its available heat.  Likewise, it is also important to remove the condensate from the heat system because if left at the bottom of a system, it reduces the efficiency of the heat transfer and it can cause several types of water hammer and thus, damage the pipe system.  Steam traps also remove air and other non-condensable gases as they reduce the efficiency of the heat transfer.  Other gases like CO2 and O2 have to be kept out of the system as well because they react to form the corrosive carbonic acid.  Steam traps open to release condensate, air and CO2 but close to keep the steam in.

    A drain trap serves as an automatic loss prevention valve.  Water or moisture may be carried with the air being used in machinery or some tools.  Presence of these elements is unwanted because it washes away the lubricating oil within these machines, accelerating wear and tear.  In instrument air systems, water can collect dirt causing sensitive instruments to fail.  In compressed air systems, excess moisture and oil tend to decrease the efficiency of the gaskets and hoses.  Removing water, moisture or oil may be done manually or using a drain trap.  A drain trap opens to discharge fluids and closes to prevent air and gas loss.
