1)
Here the max. outside diameter of the flanged welding neck must be reduced to Ø 74,5 mm the specified wall thickness,
however, must be observed.
2)
Outer pipe dimensions can also be ordered according to this standard, the standard dimensions of SN 553 must be
observed. The outside diameter of the pipe must not exceed the value M stated in the tables.
3)
The max. inside diameter must not be exceeded, the O-ring groove must be maintained as „compartment“. The demanded
pipe dimension at the joint must be adhered to. This is to be implemented by way of a typered transition or by turning off.
