Ar a laghad tá deireadh ceangail snáithe NPT fireann nó baineann ag nascóirí NPT an bhranda buaite sa chónascaire, is snáithe barrchaolaithe píopa náisiúnta Mheiriceá é NPT, ar a dtugtar snáitheanna píopa ANSI/ASME B1.20.2M freisin.

Tá tréithe thíos ag snáithe NPT:

1.Tá teascadh na bhfréamhacha agus na suaitheantais snáithe cothrom

Uillinn snáithe 2.60°

3. Is é 1° 47'24” an uillinn idir ais barrchaolaithe agus ais lár na snáithe píopa

4.Thread pitch tomhaiste in aghaidh an orlach.

Toisc go bhfuil teascadh snáithe NPT fréamhacha agus uachtair snáithe cothrom, tá sé difriúil le NPTF, mar sin ní mór téip shéalaithe PTFE a úsáid chun séala saor ó sceitheadh ​​a chinntiú, ansin séala éifeachtach a thabhairt do chónaisc ag baint úsáide as sreabhán hiodrálach.

Áirítear ar mhéideanna snáithe NPT do chónaisc Buaiteora: 1/8”-27, 1/4”-18, 3/8”-18, 1/2”-14, 3/4”-14, 1”-11.5, 1.1/ 4”-11.5, 1.1/2”-11.5, 2”-11.5.

Conas a aithint gur snáithe NPT é agus méid an tsnáithe a chinneadh?

Cigireacht 1.Visual an snáithe agus tá sé barrchaolaithe, nó úsáid a bhaint as caliper thomhas an trastomhas amach snáithe seachtracha nó an trastomhas beag snáithe inmheánach i suíomh fad éagsúla agus fuarthas amach go bhfuil an trastomhas difriúil agus freastal ar 1:16 taper, nó go díreach a úsáid. 1:16 tomhsaire cón.

2.Use caliper tomhas an trastomhas suíomh bonnlíne.Tomhais an trastomhas snáithe le caliper ID/OD, déantar trastomhas snáithe seachtrach a thomhas ar an trastomhas amach, agus an caliper a choinneáil ar uillinn bheag le haghaidh léamh níos cruinne, le haghaidh snáithe inmheánach a thomhas ar an trastomhas inmheánach, agus é a shealbhú ingearach leis. an snáithe le haghaidh léamh mná níos cruinne.

3.Measure na snáitheanna in aghaidh an orlach (TPI) nó an pháirc.Mar an trastomhas tomhaiste agus úsáid a bhaint as tomhsaire páirce coibhneasta, bain triail as tomhasairí snáithe éagsúla go dtí go gcinnfidh an t-oireann is déine, gabháil leis an oiread snáitheanna agus is féidir, tá níos mó snáithe ag gabháil, is amhlaidh is cruinne an léamh.Coinnigh an feisteas/cónascaire agus tomhsaire tuinairde an tsnáithe suas go dtí an solas, ag lorg bearnaí idir an tomhsaire agus an snáithe, is fusa é seo a fheiceáil ar fheisteas/cónascaire seachtrach snáithe ná ar fheisteas/cónascaire snáithe inmheánach.Nó déan an fad idir suaitheantas an dá snáithe a thomhas go díreach

toisc gur féidir toisí snáithe comhchosúla a bheith ag níos mó ná méid amháin.Seo thíos comparáid idir na sonraíNSnáithe PT vs snáithe BSPT, tá sé cosúil, mar sin ní mór a bheith cúramach gan mheascadh nó dul amú.
