Plastic Piping System: A Tool Against Chemical Corrosion – Part 2

PLASTIC PIPING SYSTEM: The Plastic Piping System consists of Piping Profile fabricated from plain end pipe, plain and flanged end Fittings (i.e. Elbows and Reducers) and stub-in branch connections. The Flanged Joints are Stub Ends with loose Backing Flanges. In case of Flanged Tapping Long Stub Flanges are recommended to be used in place of pipe stub-in and Short Stub ...

Plastic Piping System: A Tool Against Chemical Corrosion – Part 1

1. Introduction to Plastic Piping System: Because corrosion is a problem in operating and maintaining any Chemical Process Plant, one would prefer avoiding steel completely as a piping material but since its not feasible because of the usefulness of steel in sustaining the Pressure and Temperature conditions normally foreseen in any Process Plant. That brings the concept of composite piping ...

Impulse Trap: Kinetic Energy Operated Traps

Impulse Trap: Impulse trap is classified as Kinetic energy operated traps based on its working principle. Impulse traps cannot give a dead tight shutoff and therefore the use of impulse traps is relatively limited as compared to other types available. Construction and Working Principle of Impulse Trap: The Impulse Trap is schematically shown in the accompanying sketch (refer Figure-1). It consists of a ...

Thermodynamic Trap: Kinetic Energy Operated Steam Trap

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 ...

Balance Pressure Steam Trap

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 – A Temperature Operated Trap

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

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 Selection: How to Calculate Condensate Loads

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 ...
