1. Flat welding:chete welding yekunze layer, pasina welding yemukati layer; Inowanzo shandiswa mukati uye yakaderera kumanikidza mapaipi, iyo yezita kudzvanywa kwepombi isingasviki 0.25mpa. Kune marudzi matatu ekuisa chisimbiso pamusoro peflat welding flange, idzo mhando dzakatsetseka, concave uye convex mhando uye tenon groove mhando. Pakati pavo, mhando yakatsetseka ndiyo inonyanya kushandiswa, uye mutengo unokwanisika uye unodhura.
2. Welding yemagaro:zvose zviri mukati nekunze zvidimbu zveflangeinofanira kunge yakasungwa, inowanzo shandiswa mumapaipi epakati uye akakwirira, uye kudzvinyirirwa kwepombi kuri pakati pe 0.25 ~ 2.5mpa. Iyo yekuisa chisimbiso pamusoro pewelding flangeyekubatanidza ndeye concave uye convex, uye kuisirwa kwacho kwakanyanya kuoma, saka mutengo wevashandi, nzira yekuisa uye yekubatsira zvinhu mutengo wakakwira.

3. Socket welding:inowanzo shandiswa kudzvinyirirwa nezita ishoma pane kana kuenzana ne10.0MPa, dhayamita yezita ishoma pane kana kuenzana ne40mm mupombi.
4. Sleeve yakasununguka: Inowanzo shandiswa mupombi ine yakaderera kudzvanywa asi inoodza svikiro, saka rudzi urwu rweflange rune simba rekudzivirira ngura, uye zvinhu zvacho zvinonyanya simbi isina tsvina.
Rudzi urwu rwekubatanidza runonyanya kushandiswa kubatanidza pombi yesimbi yakakandwa, bushing hose, isiri-iron simbi pombi uyeflange valve, nezvimwewo, uye kubatana kwemidziyo yekushandisa uye flange zvakare yakabatana neflange.
