Umsonto weKontraki oMatye kunye noMsonto oMgangatho oMbi
Kukho imisonto emibini eyahlukeneyo eqhelekileyo esetyenziswa ngokubanzi kwimilomo yokuqhushumba kunye nezibambi zoqhushumbo. Ngokuqhelekileyo sasizibiza ngokuba ziCoarse Contractor Thread kunye neFine Standard Thread.
Ke uthini umahluko phakathi komsonto orhabaxa kunye nomsonto ocolekileyo? Masifunde ngabo.
Umsonto wekontraka orhabaxa yi-50mm Umsonto womgangatho woShishino kwi-4½ imisonto nge-intshi nganye (TPI) (114mm), ngoko ikwabizwa ngokuba yi-2-intshi imisonto ngamanye amaxesha. Kufana nesikrufu somthi. Kukho indawo eninzi phakathi kweentambo kwaye zikhangeleka kakhulu.
Umsonto olungileyo ubizwa ngokubaumsonto woMbhobho weMibhobho oLungileyo woMgangatho weSizwe (i-NPSM). Ngumgangatho woShishino umsonto othe ngqo osetyenziswa ngokubanzi kuMntla Melika, othiibonakala ngathi sisikrufu somatshini. Iisayizi ezimbini zomsonto ocolekileyo zisetyenziswa kakhulu kwimilomo yokuqhushumba: 1-1/4″ intambo kunye ne-3/4”-14 intambo.
Umahluko phakathi komsonto weKontraka kunye nomsonto osemgangathweni ucacile. Ubungakanani kunye nomgama phakathi kwemisonto emibini yomsonto orhabaxa wekontraki mkhulu kakhulu kunomsonto ocolekileyo. Sinokuzibona kwisithombe njengoko singezantsi.
Kwi-Coarse Contractor Thread vs. Fine Standard Thread, asiyi kuthi enye ingcono kunomnye. I-Clemco kunye ne-Contracor zibonelela ngentambo erhabaxa eyi-50mm njengomgangatho kunye netyala labo, thina apha kwi-BSTEC sithanda ukusebenzisa umsonto wekontraka njengolona hlobo lomsonto lokudubula kwemilomo kunye nabagcini. Mancinci amathuba okunqumla imisonto okanye ukubopha imisonto kuba mikhulu kwaye kulula ukuyifaka. Xa uqhushumba ngemithombo yeendaba ephucukileyo, awuzukuba nangxaki yokuncamathela kwimithombo yeendaba.
Kwi-1-1 / 4 ″ Umsonto oLungileyo, udume ngakumbi kunomsonto wekontraka eMntla Melika ngokwexesha lawo loMgangatho. Xa uthenga i-abrasive blaster evela eSchmidt, Empire, Dustless Blasting, Marco, kunye nabanye, umlomo wokuqala oza nalo matshini uya kuba yi-1-1/4 ″ intambo entle. Kungenxa yoko le nto isemgangathweni kwimarike yaseMntla Melika. Umsonto ocolekileyo uthatha ixesha elide kunomsonto orhabaxa xa ufaka, kwaye unokufumana imidiya ebambekayo xa usebenzisa imidiya entle kakhulu. Kodwa umsonto ocolekileyo unamandla angcono kwi-tensile kunye nokusebenza kokucheba kunomsonto orhabaxa womsonto wawo.
Nangona kunjalo, naluphi na uhlobo lomsonto olukhethayo, qiniseka ukuba umlomo wakho kunye nombhobho wakho odibanisa imisonto iyahambelana xa ubeka iodolo yakho. I-BSTEC ikakhulu ithwala i-50mm ye-Contractor intambo kunye ne-1-1/4″ ecolekileyo. Sikwanayo 3/4″ imisonto kwezo yunithi zincinci kunye neekhabhathi eziqhumayo.
