Ukufakwa kwesistimu yegesi
Ilangabi le-oxy-acetylene ngeke lisetshenziselwe ukusika amapayipi, futhi umsiki wepayipi ongumshini (ububanzi obulingana noma obungaphansi kuka-10mm) noma isaha likagesi lensimbi engagqwali (ububanzi obungaphezu kuka-10mm) noma indlela ye-plasma kufanele isetshenziselwe ukusika.Ingaphezulu le-incision kufanele libe bushelelezi futhi lihlanzeke, futhi ukuphambuka kobuso bokuphela akufanele kube kukhulu kuno-0.05 we-diameter yangaphandle yepayipi, futhi akufanele kudlule i-1mm.I-argon ehlanzekile (ukuhlanzeka kwe-99.999%) kufanele isetshenziselwe ukukhipha udoti nothuli ngaphakathi kwe-tube futhi kukhishwe amabala amafutha.
Ukwakhiwa kwamapayipi egesi ahlanzeke kakhulu kanye namapayipi egesi ahlanzeke kakhulu kuhlukile kumapayipi ajwayelekile egesi yezimboni.Ukunganaki okuncane kuzongcolisa igesi futhi kuthinte ikhwalithi yomkhiqizo.Ngakho-ke, ukwakhiwa kwamapayipi kufanele kwenziwe ithimba lochwepheshe, futhi kuhambisane ngokuqinile nemininingwane yokuklama nokwakhiwa, futhi kuphathe yonke imininingwane ngokujulile nangokuzibophezela ekwenzeni iphrojekthi yamapayipi afanelekayo.
Uma ukungcola ohlelweni kusatshalaliswa ngokulinganayo, ukugcwala kwegesi yokukhipha ephuma ohlelweni kuthathwa njengokugxiliswa kokungcola kwesistimu.Kodwa-ke, isimo sangempela siwukuthi nomaphi lapho igesi yangemuva yokuhlanza ihlanzekile iya khona, ukungcola kwesistimu kuzosatshalaliswa kabusha ngenxa yokuphazamiseka okubangelwe isiyaluyalu.Ngesikhathi esifanayo, kunenombolo enkulu ye "stagnation zone" ohlelweni.Igesi "esendaweni yokuma" ayiphazanyiswa kalula igesi lokuhlanza.Lokhu kungcola kungasakazeka kancane kancane ngomehluko wokugxilisa ingqondo, bese kukhishwa ohlelweni, ngakho isikhathi sokuhlanza sizoba side.Indlela yokuhlanza eqhubekayo iphumelela kakhulu kumoya-mpilo ongacondensable, i-nitrogen namanye amagesi ohlelweni, kodwa ngomswakama noma amagesi athile, njenge-hydrogen ephuma ezintweni zethusi, umphumela wawo awubi kakhulu, ngakho-ke isikhathi sokuhlanza sithatha isikhathi eside.Ngokuvamile, isikhathi sokuhlanza ipayipi lethusi izikhathi ezingu-8-20 kunepayipi lensimbi engagqwali.
