4.2.1.13.10 Vacuum relief devices and spring loaded valves shall be provided with flame arresters.

Pressure relief requirements are as indicated in 6.6.2.8.3 to prevent crystallization of the product in the pressure relief valve.

No stop valve shall be installed between the shell and the pressure relief devices except when duplicate devices are provided for maintenance or other reasons and the stop valves serving the devices actually in use are locked open or the stop valves are interlocked so that the requirements of 6.6.4.7 are always fulfilled.

The pressure relief devices shall be of a type that will resist dynamic forces including liquid surge.

The pressure relief devices shall be of the type that will resist dynamic forces including surge.

Oil pressure, 59 and steady. Fuel pressure, 3.5 and steady.

The top of the tank is provided with either a 1 mm opening which simulates the pressure relief valve (PRV) of the IBC or tank or a real PRV of a diameter which is scaled using the vent area to vessel volume ratio.

There's your tailpipe heat, your fuel pressure gauge.

Because when tankers carry oil they have to have ballast at some point, so when they're empty, they have the ballast water in there.

No stop valve shall be installed between the shell and the pressure relief devices except where duplicate devices are provided for maintenance or other reasons and the stop valves serving the devices actually in use are locked open or the stop valves are interlocked so that at least one of the duplicate devices is always in use.

Alternatively, pressurants can be removed with the use of special venting lines and pyrotechnical valves.

Vacuum relief devices, when used, shall have a cross sectional flow area not less than 284 mm2.

No stop valve shall be installed between the shell and the pressure relief devices except when duplicate devices are provided for maintenance or other reasons and the stop valves serving the devices actually in use are locked open or the stop valves are interlocked so that at least one of the duplicate devices is always operable and capable of meeting the requirements of 6.6.3.8.

The seacocks are the valves to drain out the boat.

Bundles containing UN 1045 Fluorine, compressed, may be constructed with isolation valves on assemblies (groups) of cylinders not exceeding 150 litres total water capacity instead of isolation valves on every cylinder.

The capacity and start to discharge pressure of the relief valves shall be based on the results of the tests specified in 4.2.1.13.1.

6.6.2.8.5 When the shell is fitted for pressure discharge, the inlet line shall be provided with a suitable pressure relief device set to operate at a pressure not higher than the MAWP of the shell, and a stop valve shall be fitted as close to the shell as reasonably practicable.

(a) Each plug or valve shall have a taper threaded connection directly to the pressure receptacle and be capable of withstanding the test pressure of the pressure receptacle without damage or leakage

When they come back, they actually dump this oily ballast water into the ocean.

We can squeeze the fish for oil. It's better than water.

An officer...

They ended up swimming through ballast water that had oil in it.

Sea...

Each pressure receptacle with a wall thickness at any point of less than 2.0 mm and each pressure receptacle that does not have fitted valve protection shall be transported in an outer packaging.

The dragoon, you mean?

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

(b) Each valve shall be of the packless type with non perforated diaphragm, except that, for corrosive materials, a valve may be of the packed type with an assembly made gas tight by means of a seal cap with gasket joint attached to the valve body or the pressure receptacle to prevent loss of material through or past the packing

The periodic inspection shall include an external examination, an internal examination or alternative method as approved by the competent authority, a pressure test or equivalent effective non destructive testing with the agreement of the competent authority including an inspection of all accessories (e.g. tightness of valves, emergency relief valves of fusible elements).

Two pyrotechnic valves were designed and added to the pressurization circuit of the tanks, forcing the latter to open into the void at the end of the mission.

So the valves at the bottom of those tubes there are like radio controlled airplane valves.

(d) The materials of construction for the pressure receptacle, valves, plugs, outlet caps, luting and gaskets shall be compatible with each other and with the lading.

What are the seacocks?

Open fuel valves.

4.2.1.13.7 The pressure relief devices shall consist of spring loaded valves fitted to prevent significant build up within the portable tank of the decomposition products and vapours released at a temperature of 50 oC.

6.6.2.5.6 Each stop valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperatures expected during transport.

6.6.3.5.9 Each stop valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperatures expected during transport.

6.6.4.5.8 Each stop valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperature expected during transport.
