Silos that are filled directly from a pressurised tanker need to incorporate suitable mechanisms to allow displaced air within the silo to escape during filling. If these mechanisms are insufficient for the pressures created within the silo, or if the equipment is poorly maintained and becomes inefficient, dangerously high pressures can build up within the silo. This can lead to a catastrophic blow out, damaging plant and equipment, dispersing possibly toxic silo contents over a wide area and endangering the lives of employees.
This Presentation is about the basic fundamentals one needs to know to begin Piping Engineering. All the basic formulas and questions that are usually asked in interviews are answered in this presentation. Feel free to ask any doubts in the comments and iI may try my best to answer them for you.

Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid
Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of Piping Design (or Piping Engineering). Piping systems are documented in piping and instrumentation diagrams (P&IDs). If necessary, pipes can be cleaned by the tube cleaning process.
"Piping" sometimes refers to Piping Design, the detailed specification of the physical piping layout within a process plant or commercial building. In earlier days, this was sometimes called Drafting, Technical drawing, Engineering Drawing, and Design but is today commonly performed by Designers who have learned to use automated Computer Aided Drawing / Computer Aided Design (CAD) software

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

1. PRESSURE TEST :-PRESSURE TEST :-
Introduction :Introduction :
ƒ Pressure Test is performed or conducted when
there are new or old operating equipment like
Boilers, Heat Exchangers, Pipe Connections and
other pressure vessels installed.
ƒ All pressure vessels must go through the pressure
test before they are permitted to operate.
ƒ In Malaysia, there are the regulation enforced by
Malaysian Authority under the Department of
Occupational Safety and Health (DOSH).
ƒ There are 2 pressure tests performed :-
Pressure Leak Test
Pressure Strength Test - commonly known
as Hydrostatic Test.
2. PRESSURE TEST cont :-PRESSURE TEST cont :-
Objectives :Objectives :
ƒ Fired and Unfired pressure vessels are under
government regulation, their objectives are to
prevent :-
accidents that could cause undue risk to
the personnel working at or near the plant
equipment,
accidents that could cause several severe
material damage and consequently
substantial economic losses,
accidents that could cause risk of pollution
to the environment,
downtime in plant production.
3. PRESSURE TEST cont :-PRESSURE TEST cont :-
Definition:Definition:
ƒ Design Pressure :
ƒ The pressure used in the design of a vessel.
It is manufacturer recommended design
pressure on each equipment. This design
pressure is higher than operating pressure
and it will satisfy the requirement of the
pressure of the fluid and other content of
the vessel standard.
ƒ Operating Pressure :
ƒ This is the pressure which pressure vessel
can work safely or operate normally.
4. PRESSURE TEST cont :-PRESSURE TEST cont :-
DefinitionDefinition contcont ::
ƒ Maximum Allowable Working Pressure (MAWP) :
ƒ It is the internal pressure at which the weakest element
of the vessel is loaded to the ultimate permissible point,
when the vessel is assumed to be :-
corroded condition
under the effect of a designed temperature
in normal operating condition
under the effect of other loading, like wind, external
pressure, etc.
ƒ This MAWP is higher than operating pressure.
ƒ Test Pressure :
ƒ This is manufacturer recommended hydrostatic pressure
test when the vessel or equipment is new as appeared on
the equipment name plate.
5. PRESSURE TEST cont :-PRESSURE TEST cont :-
1. Pressure Leak Test (1.10 x MAWP) :1. Pressure Leak Test (1.10 x MAWP) :
The purpose is to detect leaking paths through the
"pressure envelope" in either direction.
The methods used may be straightforward using water
or gas, like air or inner search gases.
Leakage detection may be visual or measurement of
pressure drop, pressure vacuum decay rate, trace gas
or water respond to detection instrument, audible or
ultrasonic devices, fluorescent dyes, etc.
The pressure applied in the case of trace gas techniques
should be of a very low order and for audible or visual
technique it should be equal to the working pressure of
the vessel with small multiplying factor but it should
not in any circumstances exceed 110% of the MAWP.
6. PRESSURE TEST cont :-PRESSURE TEST cont :-
2. Hydrostatic Test (1.50 x MAWP) :2. Hydrostatic Test (1.50 x MAWP) :
ƒ Is the statutory requirement of pressure vessel in
order to verify and demonstrate the continued
fitness for services.
ƒ The pressure applied may approach up to original
design pressure with a suitable correction factor
applied for the ambient design temperature
differential and deviation from the new and old
condition.
ƒ In practice, the standard hydrostatic pressure test is
equal to 150% of the MAWP.
ƒ Hydrostatic should also be applied when repairs
or modifications have been carried out which
affect the structural integrity of the pressure shell
and foundation.

Safety Requirements :Safety Requirements :
ƒ Safety Requirements :-
1Depressurising the equipment after inspection
and the test has been approved must be done by
releasing the pressure slowly through the vent
and drain valves.
2The vent valve needs to be opened to release
pressure and yo admit air when draining to
prevent collapsing of the system by pulling a
vacuum.
3Never leave equipment an attended at any time
when it is under pressure.
4Always wear safety gear when conducting
hydrostatic test.
13. ƒ The record and inspection report are to be
kept properly according to the requirements of
inspection manual of pressure vessels. It is
necessary to keep a record of all inspection
result of each vessel from the initial inspection
to the latest inspection, so that comparison
and analysis can be made from these inspection
result.
ƒ Plan and report are to be submitted for
evaluation before issuance of inspection
certificate by Malaysian Authority (DOSH).
