What is BS EN 1333 - Definition of PN of pipework components about?
BS EN 1333 is a European Standard on flanges and their joints that discusses the pipework components. The primary goal of BS EN 1333 is to offer manufacturers the best industry practices for ensuring a pipe's nominal pressure (PN), which indicates the maximum internal pressure that the pipe and its joints can withstand.
BS EN 1333 gives the definition of PN when applied to components of a pipework system, as specified in those standards which use the PN designation system.
BS EN 1333 specifies the PN numbers which are used.
Who is BS EN 1333 - Definition of PN of pipework components for?
BS EN 1333 on the definition of PN of pipework components is useful for:
- Manufacturers of pipework components
- Piping industry
- Manufactures of pipes and flanges
- Supervisor working on fluid systems and components
- Inspection bodies
Why should you use BS EN 1333 - Definition of PN of pipework components?
PN is an alphanumeric designation used for reference purposes related to a combination of mechanical and dimensional characteristics of a component of a pipework system that comprises the letters PN followed by a dimensionless number.
The maximum allowable pressure of a pipework component depends on the PN number, the material and design of the component, its maximum allowable temperature, etc.
BS EN 1333 specifies the selection of PN values for specifying both pressure class and metric flange dimensions that are used in the pipework system.
It is intended that all components with the same PN and DN designations have the same mating dimensions for compatible flange types.
As a result, if you manufacture flange joints and pipework components, according to BS EN 1333 can assist in identifying the types of pipes used for the appropriate purpose represented by PN values and demonstrating the performance and reliability of your product.
