Uyemukelwa eChuamvelo

Izinga lokuhlanganiswa lincike ekulandeleni kwakho okuqondayo nezincomo ezilandelayo.

5.1 Ukuphatha amapayipi nokuhlanganisa

Ngesikhathi se-welding, amapayipi kanye nokuqoqwa kwezindawo kufanele kube ekushiseni okuseduze okukhona, njengoba kutholwe uphethiloli wokushisa we-welder. Kufanele bavikeleke ekukhanyeni okuqondile kokukhanya kwelanga ngaphambi nangesikhathi sokufudumala, ngoba bebengafudumala kangako kunamazinga okushisa akhona, umphumela wokuncibilika we-electro-incling (okuthe xaxa kwepayipi nokuhlangana). Endabeni yokushisa okuphezulu ngokweqile, hambisa amapayipi nama-coarlings endaweni epholile, enomthunzi bese ulinda izinga lokushisa lazo ukuthi libuyele ezindaweni eziseduzane nama-ambient.

5.2 Ukulungiselela

Sika iziphetho zamapayipi ezilungiselelwe ukufudumala ngakwesokudla, usebenzisa amathuluzi afanelekile okusika amapayipi (sincoma ukusebenzisa ipayipi - bheka umfanekiso - 1 -).

Naka ngokucophelela ukugwema noma yikuphi ukugoba noma ukuvezwa kwepayipi.

5.3 Ukuhlanza

I-scleaply skrola ungqimba olungaphezulu lwe-oxidized kusukela ekugcineni kwepayipi noma kufanelekile ukusebenzisa amathuluzi afanele (Sincoma i-RTC 315 Pipe-Scraper, bheka Umdwebo - 2 -). Qiniseka ukuthi uthola iNoma kunjalo, isenzo sokushaya jikeleleEndaweni etholakala epayipweni kugcina kubandakanyeka ekusebenzeni kwe-welding, ukunwebeka okungenani okungenani i-1 cm engxenyeni ngayinye yokuhlangana. Uma lokhu kuhlanza kungenziwa ngokunembile, kuzotholwa isibopho esingesici, ngoba ungqimba oxidised luvimbela ukungena kwamangqamuzana phakathi kwezingxenye futhi ngaleyo ndlela kuphazamise imiphumela efanele yesenzo se-welding. Ukuklebhula ngephepha lesihlabathi, ama-rasps, noma amasondo okugaya ama-emery kuyintoAkufaneleke ngokuphelele.

Susa ukuhlanganiswa kusuka emaphaketheni alo kuphela ngaphambi kokuthi kusetshenziswe futhi kuhlanze ingaphakathi lokuhlanganiswa ngokuhambisana nemiyalo yomenzi.

5.4 Ukuma

Slayida imiphetho yamapayipi ku-coupling.

Kubalulekile ukusebenzisa idivaysi ehambelana nayo:

- Ukuqinisekisa ukuthi izingxenye zihlala zisesimweni esizinzile kuzo zonke izigaba zokushisa nokupholisa;

- Ukugwema noma imuphi umbandela wemishini kokuhlanganiswa ngesikhathi sokushisa nokupholisa izigaba;

(Sincoma ukusebenzisa elinye lamadivayisi avumelanayo ebangeni, bhekisa kuMdwebo - 3 -).

5.5 Ukushiswa kwe-Welding

Indawo lapho kwenziwa khona ukushisa kufanele kuvikelwe ezimweni zezulu ezingezinhle, ezinjenge-damp noma amazinga okushisa ngaphansi - 5 ° C noma ngaphezulu + 40 ° C.

Sebenzisa ikhebula namapharamitha we-welding alungele ukuhlanganisa okusebenzisayo.

5.6 Ukupholisa

Izinga lokushisa elipholile liyahlukahluka, ngokuya ngobubanzi be-couplings kanye nokushisa okukhona. Njalo uhambisana nezincomo zesikhathi zabakhiqizi bepayipi kanye nezinto ezihlanganisiwe ezisetshenziswa e-welding.

Ukususwa kwamadivayisi avumelanayo nokuxhumeka kwezintambo zokufaka izintambo kufanele kwenziwe kuphela ngemuva kokuthi isigaba sokupholisa sesiphelile.
