Thermodynamic Trap: Thermodynamic trap is classified as kinetic energy operated traps and it’s the most widely used trap in the oil and gas industry amongst all types. This thermodynamic trap has an extremely robust design and works on a simple mode of operation. It can operate at very high temperature and pressure. The means of operation for the trap is the dynamic effect of ...

Balanced Pressure Trap: As discussed in my previous post Balance pressure trap is classified under temperature operated traps. Due to robust design of the internals balance pressure steam trap has a good life expectancy.  Balanced Pressure is an improvement on the Liquid Expansion Thermostatic Trap in the sense that the above Trap is self-adjusting to varying operating steam pressure conditions within its designed ...

Liquid Expansion Trap: As discussed in my previous post liquid expansion trap is classified under temperature operated traps. Liquid Expansion Trap one of the simplest designs amongst Thermostatic type of Traps. The accompanying sketch (refer Figure-1, Exhibit 34.6) below shows the constructional features of a Liquid Expansion Trap. Figure-1 (Exhibit 34.6) It consists of an oil filled flexible thermostatic element ...

Inverted Bucket Steam Trap: As mentioned in my previous post the inverted bucket steam trap is a mechanical trap classified as a density operated steam trap which operates on the difference in density between steam and water. The accompanying sketch below shows the constructional details of an Inverted Bucket Trap. As the name implies the working portion of the Trap ...

Steam Trap Types: Based on the working principle of the Steam Trap can be classified as follows: Density Operated Steam Trap: Ball Float Inverted Bucketed Temperature Operated (Thermostatic) Steam Trap: Balanced Pressure Liquid Expansion Bimetallic Kinetic Energy Operated Steam Trap: Thermodynamic Impulse or Orifice Ball Float Steam Trap:  The Ball Float Trap works on the principal of sensing the difference ...

As I mentioned in my earlier post regarding about Steam Trap, while selecting a steam trap the most important data required is the condensate load. This data is generally provided by the process department but as a piping engineer too should be in a position to estimate the condensate loads initially. The selected steam tarp shall be functionally at the ...

Introduction: Steam is perhaps one of the most efficient mode of energy transportation in the present times in Process Industry. However it has a potential of becoming highly inefficient if certain aspects associated with its handling are not appropriately addressed in the design of steam network. The aspects, which are of particular concern with respect to efficient and safe design ...

Introduction to Gimbal Expansion Joint: The gimbal pipe expansion joint is basically same as the hinge type, except that instead of being limited to deflection in only one plane gimbal Expansion Joints are used to absorb angular rotation in any plane, using two pairs of hinges attached to a common floating gimbal ring. Gimbal systems generally consist of two gimbal ...
