2. De passingklasse van metrische draad moet 6g\/6H of hoger zijn volgens de desbetreffende voorschriften en de resterende wanddikte op het diepste punt van een afschuining of ontlastingsgroef van de binnendraad mag niet minder dan 2 mm bedragen.<\/p>\n\n\n\n
3. NPT-buitenschroefdraad met flenzen of blindstoppen moet een effectieve schroefdraadlengte hebben die niet kleiner is dan maat \u201cL2\u201d en de lengte tussen het uiteinde van de flens en de schroefdraadstaart mag niet kleiner zijn dan maat \u201cL4\u201d.
4. NPT binnendraad wordt gemeten met L1 pluggenmeter van \u201cbegraven\u201d tot \u201c2 slagen\u201d.
5. Het buitendraadgedeelte moet ten minste 8 mm lang zijn en ten minste 8 schroefdraadplaatsen bevatten. Indien de schroefdraad een ontlastingsgroef heeft, wordt een integrale en niet- samendrukbare sluitring of een gelijkwaardige voorziening aangebracht om de vereiste inschroefdraadlengte te garanderen.
*NPT Ex afdichtingspluggen hebben geen flens.
# Rekening houdend met de mogelijke afschuining of ontlastingsgroef bij installatie in de inlaat van de apparatuur, is de vereiste van 8 schroefdraadplaatsen om minstens 5 schroefdraadplaatsen te garanderen.<\/p>","protected":false},"excerpt":{"rendered":"
