We perform the following inspections at our own works on a continuous basis:<br /> •<br /> <br /> In addition to our own monitoring tests, samples of HAKATHEN® production are regularly inspected by the South German Plastics Centre at Würzburg (SKZ). HAKA.GERODUR is also an active member of the following trade associations: • SFF, Swiss Surface Heating and Cooling Association • BVF, Federal Surface Heating Association (Germany) • eu-ray, European Association for Surface Heating and Cooling<br /> <br /> Jointing method HAKATHEN® composite plastic and metal pipes can be jointed quickly and reliably by means of the HAKAPRESS system. Of course, other well proven jointing methods can also be used. Benefits of HAKAPRESS all round even pressing • all «wetted» parts made of brass are tin-plated • press-sleeve made of stainless steel, V2A • patented front seal against water from inside or condensate from outside<br /> •<br /> <br /> inspection of incoming raw materials: – melt-flow index – dry loss automatic online tests: – surface inspection of the pipe – inspection of the weld seam dimensional checks: external Ø, inner Ø and wall thickness check on the degree of cross-linkage in the inner liner to DIN 16 892 internal pressure tests for creep (conclusions regarding life expectancy) 100% testing of finished pipe rolls at high pressure followed by pilot verification of the inner diameter composite adhesion test<br /> <br /> </p> <h2>Pressure loss from HAKATHEN ® heating pipes</h2> <p> 10000 9000 8000 7000 6000 5000 4000 3000<br /> <br /> <small>Volume flow - water quantity m [kg/h]</small><br /> <br /> <small>1000 900 800 700 600 500 400 300 200</small><br /> <br /> <small>100 90 80 70 60 50 40 30 20</small><br /> <br /> mm 20 mm 6/ Ø 2 0 / 16 mm Ø2 16 mm 0/ Ø 2 0 / 154 mm Ø 218 / 1 mm Ø 13 7/ mm Ø1 12 6/ Ø1 mm 10 4/ Ø1<br /> <br /> <small>5 6 7 8 9 10 1</small><br /> <br /> <small>5 6 7 8 9 102 100</small><br /> <br /> <small>5 6 7 8 9103 1000</small><br /> <small>Pressure loss [Pa/m] (1 mbar = 100 Pa)</small><br /> <br /> </p> </div> <div> <table border="0" cellspacing="0" cellpadding="0"> <tr> <td>Sivu:</td> <td> <a href="http://novrel.netpaper.fi/4544" title="etusivu">[<small><<</small>]</a></td> <td> <a href="http://novrel.netpaper.fi/4545" title="edellinen sivu">[<small><</small>]</a></td> <td> <a href="http://novrel.netpaper.fi/4547" title="seuraava sivu">[<small>></small>]</a></td> <td> <a href="http://novrel.netpaper.fi/4547" title="takasivu">[<small>>></small>]</a></td> </tr> </table> </div> <div> <table border="0" cellspacing="0" cellpadding="0"> <tr> <td>Julkaisu:</td> <td> <a href="http://novrel.netpaper.fi/4568" title="vanhin julkaisu">[<small><<</small>]</a></td> <td> <a href="http://novrel.netpaper.fi/4562" title="vanhempi julkaisu">[<small><</small>]</a></td> <td> <a href="http://novrel.netpaper.fi/19790" title="uudempi julkaisu">[<small>></small>]</a></td> <td> <a href="http://novrel.netpaper.fi/4574" title="uusin julkaisu">[<small>>></small>]</a></td> </tr> </table> </div> </body>
