2.1 Materials<br />
Corrugated pipes<br />
The inofl ex stainless steel corrugated pipe is made of stainless steel (Mat. No. 1.4404)<br />
Screw connections<br />
The screw connection parts are made of brass (Mat. No. CuZn40Pb2) and have their own seal ring made of PTFE (FixLock).<br />
A fl at gasket is used with the fl at-sealing screw joint.<br />
2.2 Determinig dynamic pressure drop<br />
pR = l x R<br />
pR = Pressure drop of the inofl ex stainless steel corrugated pipe [Pa]<br />
l = corrugated pipe length [m]<br />
R = pressure drop of the straight mounted corrugated pipe per meter [Pa/m]<br />
Example:<br />
Stainless steel corrugated pipe DN20 (NPS 3/4”)<br />
Length = 3m (9.84 ft); volume fl ow = 100 l/h (0.37 gal/min)<br />
pR = 3m x 10 Pa/m = 30 Pa (pR = 9.84 ft x 3.05 Pa/ft = 30 Pa)<br />
see Diagram Fig. D1<br />
2.3 Permissible operating temperature and pressure<br />
With the selection of insulation materials, please observe all other usage guidelines and notes of the respective manufacturer in<br />
addition to the maximum continuous operating temperature.<br />
The following specifi cations relate to the pure „inofl ex“ corrugated pipe system!
