Izinqubo Zokushisela Ipayipi Lobungcweti: Umhlahlandlela Ophelele

Izinqubo Zokushisela Amapayipi Enkosi: Umhlahlandlela Ophelele Isithombe Esifakiwe

Incazelo emfushane:

Izinqubo zokushisela amapayipi zibalulekile ezimbonini ezehlukene ezihlanganisa ezokwakha, ezokukhiqiza, zikawoyela negesi, nokunye. Ukwazi lezi zinqubo kubalulekile ekuqinisekiseni ubuqotho besakhiwo nokuphepha kwamapayipi. Kulo mhlahlandlela ophelele, si'izongena ezicini ezibalulekile zenqubo yokushisela amapayipi, okuhlanganisa amasu, izinto zokusebenza, kanye nezindlela ezihamba phambili.

1. Qonda izisekelo zezinqubo zokushisela amapayipi

Ukushisela amapayipi kuhlanganisa ukuhlanganisa izingxenye zamapayipi ukuze kwakheke ipayipi elingavuzi eliqhubekayo. Inqubo idinga ukuqonda okuphelele kwamasu okushisela afana ne-TIG (i-tungsten inert gas), i-MIG (i-metal inert gas) kanye ne-stick welding. Ubuchwepheshe obunye bunezinzuzo nemikhawulo yabo, futhi ukukhetha kobuchwepheshe kuncike ezintweni ezifana nohlobo lwezinto ezibonakalayo, ububanzi bepayipi kanye nendawo yokushisela.

2. Ukulungiswa kokushisela kwepayipi

Ukulungiselela okwanele kubalulekile ngaphambi kokuqala inqubo yokushisela. Lokhu kuhlanganisa ukuhlanza izindawo ezizofakwa ezishiselwe, ukuqinisekisa ukuthi amapayipi afakwe ngendlela efanele nokukhetha izinto ezifanele zokushisela. Ukwengeza, kubalulekile ukulandela imigomo yezokuphepha futhi uqinisekise ukuthi indawo yokusebenza ayinazo izingozi ezingaba khona.

3. Khetha okokusebenza okufanele

Ukukhethwa kwemishini yokushisela kudlala indima ebalulekile empumelelweni yohlelo lwakho lokushisela amapayipi. Lokhu kuhlanganisa ukukhetha umshini wokushisela ofanele, ama-electrode wokushisela, amagesi okuvikela nezinye izesekeli. Kubalulekile ukutshala imali kumishini yekhwalithi ephezulu ukuze kuqinisekiswe ubuqotho bamashisela kanye nalo lonke uhlelo lwamapayipi.

4. Sebenzisa izindlela ezingcono kakhulu

Ukunamathela emikhubeni ehamba phambili kubalulekile ekuzuzeni ukushiselwa kwamapayipi okusezingeni eliphezulu nokuqinile. Lokhu kuhlanganisa nokugcina imingcele yokushisela efanele efana ne-voltage, isivinini samanje kanye nesohambo ukuze kuqinisekiswe ukungena nokuhlangana okufanele. Ukwengeza, ukulungiswa okuhlangene okufanelekile, okuhlanganisa ukulungiswa kwe-bevel kanye ne-edge, kubalulekile ekufezeni i-weld eqinile futhi enokwethenjelwa.

5. Qinisekisa Ukuthotshelwa Kwekhodi

Ezimbonini eziningi,izinqubo zokushisela amapayipikufanele ihambisane namakhodi namazinga athile ukuze kuqinisekiswe ubuqotho nokuphepha kohlelo lwamapayipi. Lokhu kungase kuhlanganise ukuthobelana nezicaciso ezifana ne-ASME B31.3, API 1104, noma i-AWS D1.1. Abahloli be-welding kanye nabahloli bokushisela kumele babe nokuqonda okuphelele kwalokhu kucaciswa futhi baqinisekise ukuthi zonke izinqubo zokushisela ziyahlangabezana nezindinganiso ezidingekayo.

6. Ukulawulwa kwekhwalithi nokuhlolwa

Ukulawulwa kwekhwalithi nokuhlola kuyizingxenye ezibalulekile zohlelo lokushisela amapayipi. Lokhu kuhlanganisa ukwenza ukuhlolwa okubonakalayo, ukuhlola okungabhubhisi (NDT) nokuhlola okulimazayo ukuze kuqinisekiswe ikhwalithi nobuqotho bokushisela. Abahloli bokushisela badlala indima ebalulekile ekuqinisekiseni ukuthi izinqubo zokushisela ziyahambisana nezidingo namazinga athile.

Kafushane, izinqubo zokushisela amapayipi zidinga inhlanganisela yobuchwepheshe, okokusebenza okufanele, ukubambelela emikhubeni ehamba phambili, nokuhambisana nezindinganiso zomkhakha. Ngokulandela lezi ziqondiso, ama-welders angaqinisekisa ukwethembeka nokuphepha kwezinhlelo zamapayipi ezinhlobonhlobo zezicelo zezimboni. Ukuqeqeshwa okuqhubekayo nokuqwashisa ngenqubekelaphambili yakamuva kubuchwepheshe bokushisela nakho kubalulekile ekwazini izinqubo zokushisela amapayipi kanye nokuzuza impumelelo kulo mkhakha.
