Accepted in principle.

With regard to ISO 6162-2 (clearance approx. 0,5 to 1,8 mm) the screw bores should be 1mm larger (H13 tolerance) compared to screw diameter for all sizes. Change d2 in table 2 as follow:

DN32 from 13,5 to 13mm

Table 2, 3 te The radius r1 of the flange head is optional. If there is not any radius the radius of the port r2 can be too large. In that case the corner of the flange can interfere with the port area which is outside of the specified surface.

To avoid interchange issues (o-ring vs. bores) d5 will be reduced to apply the same dimension as d7 from table 4.

Figure 1 right hand figure has to be corrected accordingly (d5 = d7). Remove the step.

Change d7 for DN32 from 28 to 29 in table 4.

Additionally, the screw bores have been reduced.

Table 4 te changes in d9 (O-ring diameter) changes the pressure are and could change working pressure

What were the results of these tests.

Dimension d10.

The clearance inbetween the flange bore Table 1, d4 and the flange head diameter Table 4, d10

should be 0,5 mm on both sides (in total 1 mm) for size DN 63 up to DN 80 - like for size DN 70.

The actual clearance of DN 63 and DN 80 is 3,5 / 2,5 mm and therefore much too large.

The clearance should be reduced to the recommended clearance.

The flange bore diameters Table 2, d4 are confirmed.

Therefore, the flange head diameters of size DN 63 and DN 80 should be increased.

Show test results for new flange heads. Also information on what happens if old heads are used since OD is same.

Accepted in principle

The diameter d9 has been changed within - 0,7/+0,2 mm. This has no significant impact on the working pressures. Size DN 51 was increased by 0,2 mm and DN 80 by 0,1 mm. The sizes DN 25, 51 and 80 will be tested.

By specifying clamp load, other grades/types of screws could be used with different coefficients.

Partially accepted:

Concerning clamp load see US-06. The lubricant has

the function to equalize/compensate

different friction conditions on components, such as

material, plating, fluid rests. A hydraulic oil is not

sufficient for the high contact pressures of the

threads. It requires a pasty lubricant with solid anti

friction particles. MoS2 paste is commonly used in

Table A.1

te This comment was not discussed during the meeting and is relating to findings that have been made during the agreed flange connection burst tests and their assemblies.

The torques should be reduced on some sizes to achieve more reserve to the yield strength of the 10.9 screws. The test assemblies confirmed that reduced torques work sufficient and target burst pressure ratings can be achieved without problems.

Based on the test results it is proposed to change the torques as follow:

DN 25: from 65Nm to 55Nm





DN 25: from 65 Nm to 60 Nm




AU-02 Table 4 te

This comment was not discussed during the meeting and is relating to findings that have been made during the agreed flange connection burst tests and their assemblies.

During the screw tightening for the burst tests it was recognized that on size DN 25 the gap that should be left between the port face and the flange clamp after assembly is very small (see photo at the end of the comment table) compared to the other tested sizes.

Based on the test results it is proposed to increase the flange head shoulder length ―l10‖ for DN 25 and DN 32 by 0,5 mm:

DN 25: from 9.5mm to 10.0mm

DN 32: from 10.3mm to 10.8mm
