Ochwepheshe banganikeza nokuholwa ngemikhuba yokulondolozwa kokuvimbela futhi bancome izinto ezifanele noma izingxenye zohlelo oluthile.

Ukucatshangelwa Kwezokuphepha nokuxhunyaniswa kwe-NPT

Izingozi ezingaba khona ezihambisana nokuxhunyaniswa kwe-NPT uma zingafakwanga noma zigcinwe kahle

Uma kukhulunywa nge-NPT (National Pipe Taped), kubalulekile ukuqonda izingozi ezingaba khona ezingavela uma zingafakwanga noma zigcinwe kahle. Okunye kokukhathazeka okuyisisekelo ubungozi bokuvuza. Ngenxa yokwakheka kwe-tapered of NPT CHANTS, kunethuba eliphakeme lokuvuza uma kuqhathaniswa nezinye izinhlobo zokuxhumana. Lokhu kungaholela ezinhlelweni ezahlukahlukene zokuphepha, kufaka phakathi ukungcoliswa kwemvelo, ukulimala kwemishini, kanye nokulimala komuntu.

Ukufakwa okungafanele kokuxhunyaniswa kwe-NPT kungaholela ekulimaleni kwentambo noma ukubekwa uphawu okunganele, okungaholela ekuvuzeni. Imicu yokuxhumeka kwe-NPT ithambekele ekulimaleni uma amandla ngokweqile esetshenziswa ngesikhathi sokufakwa. Kubalulekile ukusebenzisa amathuluzi namasu afanele ukuqinisekisa ukulingana okufanele futhi ugweme ukulimala kwentambo. Ngokwengeziwe, ukusebenzisa ama-balancer wentanta noma ithephu eyenzelwe ngqo ukuxhumana kwe-NPT kungasiza ukuvikela ukuvuza futhi kuqinisekiswe ukuxhumana okuphephile.

Enye ingozi ehambisana nokuxhunyaniswa kwe-NPT yikhono lokugqwala. Uma amapayipi noma ukufakwa kwenziwa ngezinto zokwakha ezingahambelani noma uma zivezwa ezintweni ezilimazayo, kungaholela ekuwohlokeni kokuxhumana ngokuhamba kwesikhathi. Ukugqwala kwenza buthaka ubuqotho bokuxhumeka, okwenza lithambekele ekuvuzeleni nasekwephuthweni. Ukuhlolwa njalo nokulondolozwa kuyadingeka ukukhomba noma yiziphi izimpawu zokugqwala futhi uthathe izinyathelo ezifanele zokuvimbela ukulimala okwengeziwe.

Izindlela zokuphepha zokuphepha okufanele zilandelwe lapho zisebenza ngokuxhumeka kwe-NPT, njengokuphatha izinhlelo eziphakeme zokucindezela nokusebenzisa imishini efanelekile yokuvikela umuntu

Ukusebenza ngokuxhumeka kwe-NPT kufaka phakathi ukuphatha amasistimu aphezulu wengcindezi, okudinga ukubambelela ngokuqinile ekuvikeleni ngokuphepha. Okokuqala nokubaluleke kakhulu, kubalulekile ukuqinisekisa ukuthi uhlelo lucindezelekile ngaphambi kokuzama noma ikuphi ukufakwa, ukugcinwa, noma umsebenzi wokulungisa. Lokhu kungenziwa ngokuvala ama-valves afanele bese kukhulula noma iyiphi ingcindezi ebanjiwe. Ukwehluleka ukucindezela uhlelo kungaholela ekukhishweni okungazelelwe kwamanzi aphezulu wengcindezelo, okubeka engcupheni enkulu ekuphepheni kwabasebenzi abathintekayo.

I-Equiptive Equipment Equipment (i-PPE) idlala indima ebalulekile ekuqinisekiseni ukuphepha kwabantu abasebenza nokuxhunyaniswa kwe-NPT. Lapho ubhekene nezinhlelo zengcindezi ephezulu, kubalulekile ukugqoka i-PPE efanelekile, njenge-goggles ephephile, amagilavu ​​kanye nezingubo zokuvikela. Ama-goggles ezokuphepha avikela amehlo ekuvuzeni okungaba khona noma izifufula, ngenkathi amagilavu ​​enikeza ukuvikela ngesandla emaphethelweni abukhali noma ezintweni ezilimazayo. Izambatho zokuvikela, ezinjengezimbobo noma ama-apors, zingavikela umzimba emikhakheni engaba khona noma ukuchitheka.

Ngaphezu kwe-PPE, kubalulekile ukulandela amasu wokuphatha okufanele lapho usebenza ngokuxhumeka kwe-NPT. Lokhu kufaka ukusebenzisa amathuluzi afanelekayo omsebenzi nokusebenzisa inani elifanele le-torque ngesikhathi sokufakwa. Ukuqiniseka ngokweqile kungalimaza imicu, kuyilapho ukuqina kungaphansi kungaholela ekuvuzeni. Kubalulekile ukushaya ibhalansi efanelekile ukuqinisekisa ukuxhumana okuphephile nokuvuzayo.

Ukuhlola okujwayelekile nokunakekelwa kubalulekile ukukhomba noma yiziphi izingozi zokuphepha ezihambisana nokuxhunyaniswa kwe-NPT. Lokhu kufaka ukubheka izimpawu zokuvuza, ukugqwala, noma ukulimala kwimicu. Noma yiziphi izingqinamba kufanele zibhekwe ngokushesha ukuvikela ukonakala okuqhubekayo futhi ziqinisekise ukuphepha okuqhubekayo nokwethenjwa kohlelo.

Ukugcina

Ekuphetheni, ukuxhumeka kwe-NPT kusetshenziswa kabanzi kwizimboni nezinhlelo ezahlukene zokuhlangana okuphephile futhi okuvuzayo. Banikela ngezinzuzo ezinjengokuhambisana nezinto zokwakha amapayipi ahlukene, ukumelana nokucindezela okuphezulu kanye nezimo zokushisa, kanye nokusebenza kwezindleko. Ukufakwa okufanele nokulungiswa kubalulekile ekufezekiseni ukuxhumana okuthembekile, kanye namathiphu wokuxazulula inkinga kungasiza ekhelini lezingqinamba ezijwayelekile. Ukuqonda ukucatshangelwa kokuphepha okuhambisana nokuxhunyaniswa kwe-NPT nakho kubalulekile ukuqinisekisa ukusebenza okuphephile kwezinhlelo.

imibuzo ejwayelekile ukubuzwa

Q:  Uyini umehluko phakathi kokuxhunyaniswa kwe-NPT ne-NPTF?

A:  NPT (I-National Pipe Thread) ne-NPTF (Kazwelonke Pipe Thread Fuel) bobabili imicu yepayipi. Umehluko omkhulu ukuthi i-NPTF inobubanzi obukhulu bezimpande zentambo kanye nobubanzi obuncane be-fret crest uma kuqhathaniswa ne-NPT. Lo mehluko uvumela ukuxhumana kwe-NPTF ukudala uphawu olunzima, kubenza balungele izinhlelo zokusebenza ezidinga ukuxhumana okuvuzayo.

Q:  Ngabe ukuxhumana kwe-NPT kungasetshenziselwa izinhlelo zombili kanye nezicelo ze-liquid?

A:  Yebo, ukuxhumana kwe-NPT kungasetshenziselwa zombili izinhlelo zokusebenza zegesi kanye noketshezi. Kodwa-ke, kubalulekile ukubheka izidingo ezithile zohlelo lokusebenza futhi uqinisekise ukuthi izinto ezikhethiwe kanye nama-sealant ziyahambisana noketshezi oluhlosiwe noma igesi.

Q:  Ingabe ukuxhumana kwe-NPT kuyahambisana namapayipi epulasitiki?

A:  Ukuxhumana kwe-NPT ngokuvamile kuyahambisana namapayipi epulasitiki. Kodwa-ke, kubalulekile ukubheka uhlobo oluthile lopulasitiki olusetshenziswayo futhi uqinisekise ukuthi ukuxhumana okukhethiwe kwe-NPT kuyahambelana nale nto ethile. Amanye amapulasitiki angahle adinge ama-adaptha akhethekile noma ukufakwa kokuqinisekisa ukuxhumana okufanele nokuvikelekile.
