ASTM A 53 inovhara isina musono uye welded simbi pombi ine zita remadziro ukobvu.Mamiriro epamusoro anowanzo kuve dema uye ASTM A53 pombi (inonziwo ASME SA53 pombi) inoitirwa mashandiro emakanika uye kumanikidza uye zvakare inogamuchirwa kune yakajairika kushandiswa muutsi, mvura, gasi uye mhepo mitsara.Yakakodzera kukwirisa uye kugadzira maoparesheni anosanganisira kukoira, kukotama, uye flanging.A53 isina musono simbi chubhu chinhu cheAmerican standard steel pombi.Iyo huru yekugadzira maitiro eA53 isina musono simbi machubhu yakakamurwa kuita inotonhora kudhirowa uye inopisa kutenderera.Musiyano mukuru uripo pakati pezviviri izvi ndewekuti magadzirirwo epombi anotonhora akakungurutswa esimbi asina musono anowanzo kuomarara kupfuura ayo ekutenderera anopisa, uye kutaridzika kweinotonhora yakakungurutswa simbi isina musono pombi ipfupi pane iyo inopisa inokunguruka.Simbi yakakungurutswa isina musono pombi, kukora kwemadziro kweinotonhora-yakamoneredzwa seamless kabhoni simbi pombi kazhinji idiki pane iya inopisa-yakakungurutswa isina seamless kabhoni simbi mapaipi, asi kumusoro kunotaridzika kupenya.Kumusoro kwehot-yakakungurutswa kabhoni simbi chubhu inenge yakaoma.Iyo huru yekugadzira inotenderedza chubhu isina chinhu → kudziyisa → kubaya → matatu-roll skew kutenderedza , inoenderera ichimonereka kana extrusion → kubviswa kwechubhu → saizi (kana kudzikisa dhayamita) → kutonhora → kutwasa → hydraulic test (kana kuona kukanganisa) →maka → yekuisa raibhurari.

1. Iyo huru yekugadzira nzira yekupisa-yakakungurutswa seamless simbi pombi (main inspection process):
Tube kugadzirira uye kuongorora → chubhu isina kupisa kupisa → kubaya → chubhu kutenderedza → simbi kudzoreredza → yakagadzika (yakadzikiswa) dhayamita → kurapa kupisa △ → yapedza kutwasanura chubhu → kupedza → kuongorora (isingaparadze, yemuviri uye makemikari, Taiwan kuongorora) → imba yekuchengetera
2. Iyo huru yekugadzira nzira yekutonhora-yakakungurutswa (yakadhonzwa) isina musono pombi dzesimbi:
Kugadzirira billet → kunhonga lubrication → kunotonhora kukungurutsa (kudhirowa) → kurapwa kupisa → kururamisa → kupedza → kuongorora
