   ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)

3. Log splitter - Wikipedia

   en.wikipedia.org/wiki/Log_splitter

   A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Many log splitters consist of a hydraulic pump or electric motor which then powers a hydraulic or electrical rod and piston assembly.

4. Separator (oil production) - Wikipedia

   en.wikipedia.org/wiki/Separator_(oil_production)

   Safety relief valves A spring-loaded safety relief valve is usually installed on all oil and gas separators. These valves normally are set at the design pressure of the vessel. Safety relief valves serve primarily as a warning, and in most instances are too small to handle the full rated fluid capacity of the separator. Full-capacity safety ...

5. Desmodromic valve - Wikipedia

   en.wikipedia.org/wiki/Desmodromic_valve

   A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...

6. Minor losses in pipe flow - Wikipedia

   en.wikipedia.org/wiki/Minor_Losses_in_pipe_flow

   Minor losses in pipe flow are a major part in calculating the flow, pressure, or energy reduction in piping systems. Liquid moving through pipes carries momentum and energy due to the forces acting upon it such as pressure and gravity.

7. Texas City refinery explosion - Wikipedia

   en.wikipedia.org/wiki/Texas_City_Refinery_explosion

   The splitter tower mechanical conditions were seen as degraded, so in 2004 the set point of the pressure relief valves was decreased from 70 psi (480 kPa) to approximately 40 psi (280 kPa). If this change had not been implemented, the valves would not have opened on the day of the accident and the explosion would not have occurred, because the ...
