Njengoko igama lisitsho, umsonto wepayipi ubhekisa kumsonto osetyenziswa kumbhobho. Apha, umbhobho ubhekisa kumbhobho oqhelekileyo. Ekubeni olu hlobo lombhobho lubizwa ngokuba ngumbhobho oqhelekileyo, umsonto wepayipi ngokwenene ngumsonto oqhelekileyo. Imisonto yepayipi, njengohlobo loqhagamshelwano lombhobho, isetyenziswa kakhulu ekuqhagamshelweni nasekutywinweni kwemibhobho emincinci nephakathi ethwala ulwelo kunye neegesi. Kukho iintlobo ezintathu eziqhelekileyo zemisonto yepayipi. Zezi: umsonto we-NPT, umsonto we-BSPT, kunye nomsonto we-BSPP.
Umahluko ophambili phakathi kweentlobo ezintathu zemisonto:
| Umsonto wePipe | I-engile | I-Taper/Parellel | Phezulu nasezantsi | Ifomu lokutywina | Umgangatho |
| I-NPT | 60° | I-Tapered | Phezulu Phezulu, ezantsi Phezulu | Isigcwalisi | I-ASME B1.20.1 |
| I-BSPT | 55° | I-Tapered | Ingaphezulu ejikelezileyo, ezantsi ejikelezileyo | Isigcwalisi | I-ISO7-1 |
| I-BSPP | 55° | I-Parellel | Ingaphezulu ejikelezileyo, ezantsi ejikelezileyo | I-Gasket | I-ISO228-1 |
Imigaqo yokutywina kunye neendlela zokutywina zeentlobo ezintathu zemisonto yepayipi
Nokuba yintambo yombhobho etywiniweyo engama-55° (BSPT) okanye umsonto wombhobho otywiniweyo oyi-60° (NPT), isibini somsonto kufuneka sizaliswe ngesixhobo esiphakathi ngexesha lokukrufula. Ngokubanzi, iteyiphu yokutywina ye-PTFE isetyenziselwa ukusonga umsonto wangaphandle, kwaye inani lee-wraps liyahluka ukusuka kwi-4 ukuya kwi-10 kuxhomekeke kubukhulu beteyiphu yokutywina ye-PTFE. Xa umsantsa phakathi komphezulu nomzantsi wezinyo ulungelelanisiwe, uyaqina ngokuqiniswa komsonto wombhobho. Imisonto yangaphakathi neyangaphandle icinezelwa omnye komnye, kuqala kususwe umsantsa phakathi kwamacala acinezelweyo. Emva koko, njengoko amandla okuqinisa esanda, umphezulu wezinyo uba bukhali kancinci kancinci, umzantsi wezinyo uba buthuntu kancinci kancinci, kwaye umsantsa phakathi komphezulu wezinyo nomzantsi wezinyo uyanyamalala kancinci kancinci, kufezekiswa injongo yokuthintela ukuvuza. Xa kukho utshintsho okanye ukuphazamiseka phakathi komphezulu nomzantsi wezinyo, baqala bacinezele omnye komnye, okubangela ukuba umphezulu wezinyo ube buthuntu kancinci kancinci kwaye umzantsi wezinyo ube buthuntu kancinci kancinci, kwaye emva koko izinyo liqhagamshelane kwaye lisuse umsantsa kancinci kancinci. Ngaloo ndlela kufezekiswa umsebenzi wokutywina komsonto wombhobho.
Umsonto wepayipi ongatywinwanga we-55 ° (BSPP) ngokwawo awunawo umsebenzi wokuvala, kwaye umsonto usebenza kuphela njengomsebenzi wokudibanisa. Ke ngoko, i-gasket yokutywina iyadingeka ukuze kuvalwe ubuso obupheleleyo. Kukho iindlela ezimbini zokutywina ubuso obupheleleyo: enye kukusebenzisa i-gasket esicaba kubuso obuphelileyo bomsonto wesilisa, kwaye enye kukusebenzisa i-gasket edibeneyo (i-gasket ye-elastic efakwe kwicala langaphakathi lendandatho yesinyithi) kubuso obuphelileyo bomsonto wesifazane.
