Spiral submerged arc welded steel pipe nthawi zina amakumana ndi zochitika zina popanga, monga mabowo a mpweya.Pakakhala mabowo a mpweya mumsoko wowotcherera, zimakhudza mtundu wa payipi, kutulutsa payipi ndikuwononga kwambiri.Pamene chitoliro chachitsulo chikugwiritsidwa ntchito, chidzachititsanso dzimbiri chifukwa cha kukhalapo kwa mabowo a mpweya ndikufupikitsa nthawi yautumiki wa chitoliro.Chomwe chimayambitsa mabowo a mpweya muzitsulo zozungulira zitsulo zowotcherera msoko ndi kukhalapo kwa madzi otuluka kapena dothi powotcherera, zomwe zingayambitse mabowo a mpweya.Pofuna kupewa izi, muyenera kusankha zofanana flux zikuchokera kuti sipadzakhala pores pa kuwotcherera.
Pamene kuwotcherera, makulidwe a solder kudzikundikira adzakhala pakati pa 25 ndi 45. Pofuna kupewa mpweya mabowo pamwamba pa ozungulira zitsulo chitoliro, pamwamba zitsulo mbale ayenera kuthandizidwa.Pa kuwotcherera, zinyalala zonse zazitsulo ziyenera kutsukidwa kaye kuti zinthu zina zisalowe mumsoko wowotcherera ndikutulutsa mabowo a mpweya pakuwotcherera.
