BS ISO 10763:2020,Hydraulic fluid power — Plain-end, seamless and welded precision steel tubes — Dimensions and nominal working pressures.BS ISO 10763:2020 pdf free download.
BS ISO 10763:2020 specifies sizes and nominal working pressures for seamless and welded precision steel tubes with outside diameters in accordance with ISO 4397, and wall thicknesses and mechanical properties in accordance with ISO 3305. The nominal working pressures included in this document reflect a design factor ratio of 4 to 1 applied to the calculated burst pressures.
In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit.
Components may be connected through their ports by connections (fittings)and conduits. Tubes are rigid conduits.
