What is the basic difference between the Pressure equipment directive and the pressure equipment safety regulations?
The pressure Equipment Directive is a European Directive intended for all member states of the EU. European directives are extremely difficult to police and enforce, so they are simply a directive which the respective governments must adhere to. It was initially intended to ensure a common standard of manufacturing safety and workmanship control, by stipulating design documentation, testing, material control and traceability, and inspection requirements during construction and fabrication of pressure equipment. By doing so, the standard and safety of pressure equipment across the boundaries of EU states, became more uniform, hence it resulted in a virtual removal of trade barriers. The Pressure Equipment Regulations are a means of an individual state (in this case UK) of legally enforcing the requirements of the PED.

What is the difference between a compressible fluid and an incompressible fluid?
The density of a compressible fluid changes with pressure, while the density of an incompressible fluid is not affected by pressure (assuming isothermal conditions).
What is the difference between vessel and drum in chemical engineering or petroleum industry?
I think a vessel is containing a fluid under high pressure whereas a drum contain a fluid with no or low pressure.
What is the difference between Retrievable and Retractable corrosion probes?
Retrievable corrosion probes is meant for high pressure (3600 to 6000 psig). Retractable corrosion probes is meant for pressure about 1500 psig.
How is an accumulator used at the oil refinery?
In an oil refinery, an accumulator serves as a pressure storage device for hydraulic fluids and can help manage pressure fluctuations in various processes. It stores excess fluid under pressure, allowing for a steady supply during peak demand, ensuring that equipment operates efficiently and safely. Additionally, accumulators can assist in emergency shutdown systems by providing backup pressure to control systems when needed. Overall, they enhance the reliability and efficiency of refinery operations.
Can you buy small cylinders of nitrogen for home brew?
In the UK you can rent small cylinders of Nitrogen and mixtures of Carbon Dioxide and Nitrogen for dispensing home brew, you can not buy the cylinder for safety and legal reasons, you pay a charge for the gas and a monthly rent for the cylinder.
When did Pressure Equipment Directive happen?
The Pressure Equipment Directive (PED) was established in 1997 and came into effect on May 29, 2002. It sets the essential safety requirements for pressure equipment used in the European Union to ensure a high level of protection for public health and safety.
What are PED hose?
PED hoses, or Pressure Equipment Directive hoses, are specialized hoses designed to meet the safety and performance requirements outlined by the European Union's Pressure Equipment Directive. These hoses are typically used in industrial applications involving the transport of fluids under pressure, ensuring compliance with safety standards. They are constructed from materials that can withstand high pressures and temperatures, making them suitable for various applications, including chemical processing and hydraulic systems. Compliance with the PED ensures that these hoses are safe for use in environments where pressure-related hazards exist.
What is the criterion for deciding the hydro test pressure in relation to the design pressure of a pressure vessel?
It depends on which Directive the vessel has to be compliant with. For instance, to comply with CE/PED, the test pressure shoud be 1.43 times the maximum operating pressure.
A pressure difference is also known as an?
A pressure difference is also known as a pressure gradient.
Who manufactures high pressure washing equipment?
What are the names of some manufacturers of high pressure washing equipment? Either commercial or consumer grade equipment is ok.
What mean by OEM pressure?
Original Equipment Manufacturer pressure.
What should never be used on aircraft landing gear components?
High pressure wash equipment
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
Why is there a time delay in an oil safety control?
Generally oil safety switches sense the oil pressure. If there is no preset pressure then the oil safety switch acts (to switch off or cut off the device) For an equipment that needs to be protected against the low oil pressure, such switches are used. when the equipment is standstill (or not running) then the oil pressure is also zero. When the equipment starts running, during the initial few seconds the oil pressure builds up from zero to required pressure. The timer is required not to cut off the equipment control in this initial few seconds. Control system waits for few seconds allowing the pressure to build up and after the preset time, if the pressure does not build up then it switches off the equipment since running the equipment with oil pressure is not good for the equipment.

What are the effects of 9 atmospheres of pressure on deep-sea exploration equipment?
The effects of 9 atmospheres of pressure on deep-sea exploration equipment can include increased stress on the equipment, potential structural damage, and the need for specialized materials to withstand the pressure.
What is the difference between static pressure and dynamic pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
