Trykkrav

Trykkrav is a term used in Danish and Norwegian technical documentation that translates roughly to "pressure requirement" or "pressure specification." It denotes the specified pressure level a component, system, or process must meet or stay within during design, manufacturing, operation, and testing. The concept is applied in fields where pressure is a critical parameter, such as piping systems, pressure vessels, gas and water supply networks, and HVAC installations.

In practice,trykkrav encompasses several related pressures. These include operating pressure (the pressure expected during normal service), design pressure (the value used for safety analysis and component sizing), maximum allowable working pressure (MAWP), and test pressure (the pressure used to verify integrity through hydrostatic or pneumatic testing). Designers determine trykkrav from anticipated loads, material strength, safety factors, and applicable codes or standards. Documentation, drawings, and procurement specifications commonly state the requiredtrykkrav to ensure safety and performance.

Regulatory context commonly links trykkrav to standardized pressure limits and testing regimes. National and international standards for pressure vessels, piping, and related equipment specify how design pressure is calculated, what test pressures are required, and how compliance is demonstrated.

Limitations: The term is most commonly used in Danish and Norwegian contexts, so in English-language materials it is often translated as "pressure specification" or "pressure requirement." The exact definitions and values for trykkrav can vary by industry, country, and standard adopted for a given project.
