• Installation material, see page 3.
• Pipe and operating pressures,
see Section 6 “Limits”.
• Flange spacing
= dimension “a” + 2 x gasket thickness of D2
(dimension “a”: see Sect. 11 “Dimensions and weights”;
arrangement of gaskets: see Sect. 7 “Grounding”).
• High-temperature pipelines
Where process temperatures exceed 100 °C/212 °F, provide for facilities to
compensate for longitudinal expansion on heat-up of the pipeline.
For short pipelines use resilient gaskets and
for long pipelines install flexible pipe elements (e.g. elbows).
• Position of flanges • Torques
Install flowmeter in line with the pipe For all flanged instruments to DIN, ANSI
axis. Pipe flange faces must be and JIS
