Chii chinonzi high-simba square chubhu?

Maitiro ekuita zvehigh-simba square tubevane simba rakakwirira, kusimba kwakanaka uye kupikisa kwemaitiro.
Simba: goho poindi ( σ s）≥390mpa;
Tensile simba (б b)≥635mpa;
kureba δ 5（%）≥25;
Kuoma hb ≤ 187hv,
Tsanangudzo yekurapa kwekupisa: normalizing 850 ° C;Kudzima 880 ° C;Kupisa 600 ° C.
Material: yakagadzirwa nemhando yepamusorocarbon structural simbinekukunguruka kunopisa kana kutonhora kudhirowa.
Kushandiswa: inoshandiswa kugadzira mvura-yakatonhorera madziro pombi, kuvira mvura pombi, locomotive mvura tank steam pombi uye arch zvidhinha pombi, nezvimwe.
Tsanangudzo uye chimiro chemhando:
Batch rimwe nerimwe remapaipi esimbiInofanira kuongororwa imwe neimwe, uye pasi haifaniri kuva nepakatsemuka, napakapetwa, kana pakakanganiswa paganda.Ultrasonic chikanganiso chekuonekwa chichaitwa kune imwe neimwe pombi yesimbi kuti iongorore ma mechanic properties ye weld.Kazhinji, iyo longitudinal yekusimbisa dhayamita yeweld ndeye 0.2-0.25mm, iyo longitudinal yekusimbisa dhayamita ye circumferential weld ndeye 0.75-1mm, uye iyo longitudinal yekusimbisa yekusimbisa pasocket haizove isingasviki 0.25mm
Mushonga weKemikari Kuumbwa kwemakemikari echigadzirwa chakapedzwa kunoenderana nezvinodiwa zveGB 222-84.
Zvenyama uye zvemuchina:
1) Iyo yekushushikana-kurovera curve yetensile bvunzo ichave yakati sandara pasina kuchinja kamwe kamwe
2) Impact bvunzo Iyo yakaderera-tembiricha kukanganisa kuoma kweiyo sampuli inoedzwa neinotonhora yekukotama bvunzo nzira pane yakatarwa tembiricha.
3) Kutsemuka hakubvumidzwe pamapombi anopiswa ne hydraulic kana pneumatic zvishandiso
4) Kushushikana kusiri-kufanana kwekukotama bvunzo hakupfuurire kukosha kwakatarwa.
Kuyerera kwemaitiro: Mushure mekunge simbi tambo yaiswa otomatiki kuita yakaonda dhisiki chimiro uye ichiramba ichigadzirwa, inokwenenzverwa ne-multi-pass straightener, uye yozopinda mune yakakwirira-frequency welding unit.Migumo miviri iyi yakasungwa ne high-frequency lap welder kuti iite denderedzwa corrugated welding.Mushure mekuputika, pombi yesimbi yakakura uye inochekwa nehukuru uye kucheka unit.Pakupedzisira, pombi yesimbi inodzimwa uye inodzivirirwa neyokupedzisa unit, uye yobva yapfapfaidzwa neprimer kuti ipedze basa rekugadzira.
