1. Kutenga kunoda kunzwisisa marudzi emapombi esimbi:
A. Yakakamurwa nemhando: yakatwasuka musono simbi pombi, musono simbi pombi, spiral simbi pombi, etc.
B. Kupatsanurwa kwepamuchinjikwa-chikamu maumbirwo emusono seam simbi mapaipi: sikweya pombi, rectangular pombi, elliptical pombi, flat ellipse pipe, semicircular pombi, nezvimwewo.

2. Pfungwa dzekucherechedza:
A. Ukobvu hwemadziro epombi yesimbi hauna kukwana. Kushandisa gedhi zvinoreva, muromo wepombi yesimbi unotaridzika wakakora nenhoo yesando, asi chimiro chepakutanga chichafukunurwa nekuyera nechiridzwa.
B. Shandisa mitsara yakatwasuka semapombi esimbi asina musono. Huwandu hwemasamu akatwasuka welds ishoma pane imwe longitudinal weld. Iyo pombi yakasimba yesimbi inokwenenzverwa nemuchina, unozivikanwa seporizha. Zvinoita sekunge hapana gap rekuve seamless.
C. Ikozvino kuchine imwe yakanyanyisa nzira ndeye musono simbi pombi, iyo iriwo thermally akawedzera simbi pombi. Mushure mekuwedzera, kune hupfu hwemutobvu mukati, uye kune mavanga ekutsva kunze. Iwo welds akafanana asingaoneki. Mapaipi akawanda esimbi akakura zvakati kurei anotengeswa zvisina musono achishandisa rudzi urwu rwepombi yesimbi kutsvaga purofiti yakakura.
D. Circumferential welded seam simbi pombi dzinoshandisa polishing kumiririra mapombi esimbi asina musono nemapombi esimbi akatwasuka.
