Flangejiolisengenasiphelosithimetal bhetyebhetye amazinkihyonkefor pipeline. Kwimveliso ye-hose yensimbi, eyona nto ibalulekileyo yintsimbi yentsimbi. Ngoko ke, ulawulo olungqongqo kuyo yonke imiba yokuvelisa i-bellows sisiqinisekiso esibalulekileyo somgangatho wemveliso.

Ngokweemfuno zokuphakama kwamaza ahlukeneyo, umgama wamaza kunye nezinye iinkcukacha zokusetyenzwa kwemveliso, ukuveliswa kwemvulo.

INdibano, i-welding iyisitshixo esibalulekileyo ekubunjweni kwemveliso, ukuba neteknoloji enamandla kunye nesimo sengqondo.

Yonke imveliso iya kuvavanywa phambi kokuthunyelwa, kwaye rhoqo ukulandela umgangatho.
