Hello everyone, I want to confirm an information about the hight of the foam dam. We disagreed with a contractor about the interpretation of the following statement in the designe criteria: '' Dam height shall be at least 2 in. (51 mm) higher than any burnout panels in metal secondary seals''...

I want to understand the downsides of the amplitude on the surface being too rough and the relationship between surface roughness and the degree of cleanness (Sa2, Sa2.5,... SA3). From what I know, the peaks of metal will be exposed through the primary coat, but what if we thikens the primary a...

Hello All, Looking at the method of using patch repair plates on the tank Bottom in accordance with API653 does API 653 states any maximum size of patch plates? what to do if you find several adjacent damaged plates on the bottom of the tank? Can you cover a whole part of the bottom with new...

Hi, I want to know which standards are used to design the fire-water protection piping network in an oil storage farm. Thanks

I need information on regenerative desiccant dryers sizing. I couldn't find a book that talk about this subject. So please help me if you know any book!

we want to open a window or a door in the shell of a 220 ft diameter oil storage tank. what do the standards ( API650, API653) say about it and in what sections I can find it. the door si about a 6.5 by 6.5 ft and we want to open it so we can repair the tank's bottom.

I need to know the most important specifications and caracteristics of corrosion inhibitors that i need to demand from a contractor who is providing them to us. we need the inhibitors to use them in hydrostatic tests for oil storage tanks.

we have a crude oil storage tank that has a very damaged 1st shell. Pittings are Spread on most of the underside area of the 1st shell plates( about 40 cm from the bottom). the thickness loss is in some places about 66% of the original thickness. the shell original thikness is 22 mm ( 0.866...

After cleaning an oil storage tank for reparation..what's the best way to chase the residual flamable gases underneath the tank bottom to avoid problems when the welding starts?.

1. Is using products like Belzona epoxy effective for repairing corroded areas on the bottom of an oil storage tank. Is that allowed by the API 653.. 2.what's the limit where it is better to put a new bottom than repairing the old one by welded patches?

what's the best way to detect leaks after opening a petroleum storage tank for reparation. in my work place we inject water under the tank bottom. What does API 653 says about that? and is using Helium better?

Hi, I'm a mechanical engineer and I moved recently to storage tank departement.. I need a detailed description of the correct procedures to completely rehabilitate an API storage tank according to the API 653

Hi, we have a gas turbine GE Frame 3 that is started by a diesel engine and we want to study the possibility of changing the system to a pneumatic starter. what I don't understand is why does the diesel engine has a torque converter even though its torque is usually higher than an air...

We have a compressor that compresses an associated gas (gas separated from oil). But although all the filtration we always have contamination of the dry gas seals by oil. What are the possible causes of this contamination knowing that the filtration is by the standards? Why always the failure...

can someone explain in details the air/gas turbo-starters that are used to start gas turbines..what are their main components? how does they work?..any links or documents that talk about them theoricaly because I've only found Industrial and commercial links

hi, I'm a mechanical engineer..I'm new to turbines, I don't know alot about them....we have an old gas turbine that is started by a diesel engine coupled through a torque converter... it's a very old engine and we don't have any documents about it..I'm trying to understand the starting...

we have at my work place pumps that have different outlet pressure, 11 bars and 8 bars pumps I want to know if there is a methode to combine the pumps together (parallel) in the same pipeline

Hi, I'm working at an oil pumping station. We have two gas turbines that have diesel motors as a starting system and they asked me to study the possibility of changing them with turbo-starters because the diesel motors are very old and their spare parts no longer exist in the market. I haven’t...
