Ukuqonda Izinqubo Zokushisela Amapayipi: Umhlahlandlela Ophelele

Incazelo emfushane:

Izinqubo zokushisela amapayipi zibaluleke kakhulu ezimbonini ezahlukahlukene okuhlanganisa ezokwakha, ezokukhiqiza, uwoyela negesi, nokuningi. Ukwazi lezi zinqubo kubalulekile ekuqinisekiseni ubuqotho besakhiwo kanye nokuphepha kwamapayipi. Kulesi siqondiso esiphelele, sibheka'Ngizogxila ezicini ezibalulekile zenqubo yokushisela amapayipi, okuhlanganisa amasu, imishini, kanye nemikhuba emihle kakhulu.

1. Qonda izisekelo zezinqubo zokushisela amapayipi

Ukushisela amapayipi kuhilela ukuhlanganisa izingxenye zamapayipi ndawonye ukuze kwakheke ipayipi eliqhubekayo nelingavuzi. Le nqubo idinga ukuqonda okujulile ngamasu okushisela njenge-TIG (igesi ye-tungsten inert), i-MIG (igesi ye-metal inert) kanye nokushisela okunamathelayo. Ubuchwepheshe ngabunye bunezinzuzo nemikhawulo yalo, futhi ukukhetha ubuchwepheshe kuncike ezintweni ezifana nohlobo lwezinto, ububanzi bepayipi kanye nendawo yokushisela.

2. Ukulungiselela ukushisela amapayipi

Ukulungiselela okwanele kubalulekile ngaphambi kokuqala inqubo yokushisela. Lokhu kuhlanganisa ukuhlanza izindawo ezizoshiselwa, ukuqinisekisa ukuthi amapayipi afakwe kahle nokukhetha izinto zokushisela ezifanele. Ngaphezu kwalokho, kubalulekile ukulandela izinqubo zokuphepha nokuqinisekisa ukuthi indawo yokusebenza ayinazo izingozi ezingaba khona.

3. Khetha imishini efanele

Ukukhethwa kwemishini yokushisela kudlala indima ebalulekile empumelelweni yohlelo lwakho lokushisela amapayipi. Lokhu kuhlanganisa ukukhetha umshini wokushisela ofanele, ama-electrode okushisela, amagesi okuvikela kanye nezinye izesekeli. Kubalulekile ukutshala imali emishinini esezingeni eliphezulu ukuqinisekisa ubuqotho bemishini yokushisela kanye nohlelo lonke lwamapayipi.

4. Sebenzisa izindlela ezinhle kakhulu

Ukunamathela emikhubeni emihle kubalulekile ekufinyeleleni ukushisela kwamapayipi okuseqophelweni eliphezulu nokuqinile. Lokhu kuhlanganisa nokugcina imingcele efanele yokushisela njenge-voltage, i-current kanye nesivinini sokuhamba ukuqinisekisa ukungena nokuhlanganiswa okufanele. Ngaphezu kwalokho, ukulungiswa kwamalunga okuhlangana okufanele, okuhlanganisa ukulungiswa kwe-bevel kanye nomphetho, kubalulekile ekufinyeleleni ukushisela okuqinile nokuthembekile.

5. Qinisekisa Ukuthobela Imithetho

Ezimbonini eziningi,izinqubo zokushisela amapayipikumele balandele amakhodi nezindinganiso ezithile ukuqinisekisa ubuqotho nokuphepha kohlelo lwamapayipi. Lokhu kungafaka phakathi ukuhambisana nemininingwane efana ne-ASME B31.3, API 1104, noma i-AWS D1.1. Abashiseli nabahloli bokushisela kumele babe nokuqonda okuphelele kwalezi zincazelo futhi baqinisekise ukuthi zonke izinqubo zokushisela ziyahlangabezana nezindinganiso ezidingekayo.

6. Ukulawulwa kwekhwalithi nokuhlolwa

Ukulawulwa kwekhwalithi nokuhlolwa kuyizingxenye ezibalulekile zohlelo lokushisela amapayipi. Lokhu kuhlanganisa ukwenza ukuhlolwa okubonakalayo, ukuhlolwa okungabhubhisi (NDT) kanye nokuhlolwa okubhubhisayo ukuqinisekisa ikhwalithi nobuqotho bezinto zokushisela. Abahloli bokushisela badlala indima ebalulekile ekuqinisekiseni ukuthi izinqubo zokushisela ziyahambisana nezidingo nezindinganiso ezithile.

Ngamafuphi, ukuba yingcweti yezinqubo zokushisela amapayipi kudinga inhlanganisela yobuchwepheshe, imishini efanele, ukunamathela emikhubeni emihle kakhulu, kanye nokuhambisana nezindinganiso zemboni. Ngokulandela lezi ziqondiso, abashisela bangaqinisekisa ukuthembeka nokuphepha kwezinhlelo zamapayipi ezinhlotsheni ezahlukahlukene zezicelo zezimboni. Ukuqeqeshwa okuqhubekayo kanye nokuqwashisa ngentuthuko yakamuva kwezobuchwepheshe bokushisela nakho kubalulekile ekuqondeni izinqubo zokushisela amapayipi nokufeza ubuhle emkhakheni.
