Seamless simbi pombi yemaboilers imhando yeboiler pombi uye ndeyechikamu cheiyo seamless simbi pombi. Nzira yekugadzira ndiyo yakafanana neyemapombi esimbi asina musono, asi pane zvinodiwa zvakasimba kune rudzi rwesimbi inoshandiswa mukugadzira mapaipi esimbi. Seamless simbi mapaipi e boilers anowanzoshandiswa pasi pekushisa kwepamusoro uye kudzvinyirira kwakanyanya. Pasi pechiito chepamusoro tembiricha flue gasi uye mhute yemvura, mapaipi anozoita oxidize uye corrode. Mapombi esimbi anodiwa kuti ave nesimba rakasimba rekugara, kupikisa kwakanyanya kune oxidation uye ngura, uye kugadzikana kwakanaka kwechimiro. Mapombi esimbi asina musono emaboilers anonyanya kushandiswa kugadzira mapombi akanyanya-kudzvanywa, mapombi makuru eupfu, nezvimwe.

Yakaderera uye yepakati pressure boiler machubhuGB3087 uyeboilers isina musono machubhuGB5310 zvinhu zvemhando yepamusoro-soro zvinoshandiswa kugadzira mapaipi anopisa anopisa, mapombi emvura anofashaidza epasi-kudzvanywa boilers ezvimiro zvakasiyana, mapombi anopisa anopisa emagetsi emagetsi, pombi hombe dzehutsi, pombi diki dzeutsi uye arch zvidhinha pombi.
