Technical zvinodiwa kutipombi flange forgings(kusanganisiraforgeduyezvidimbu zvakakungurutswa).
1.The giredhi uye unyanzvi zvinodiwa zveforgings(kusanganisirazvimedu zvakaumbwa uye zvakakungurutswa) ichaita zvinoenderana nezvinodiwa zveJB4726-4728.
2.Nominal pressure PN 0.25 MP 1.0 MPa carbon steel uye austenitic stainlessforgings dzesimbiyakabvumira kushandiswa kwemazinga Ⅰ forgings.
3.Pamusoro pezvirongwa zvinotevera, kudzvanywa kwezita kwePN 1.6 MPa kusvika 6.3 MPa forgings kuchaenderana ne Ⅱ level kana pamusoro penhanho Ⅱ.forgings levels.
4.Mune imwe yeinotevera inofanirwa kuenderana nezvinodiwa zve Ⅲ uyeforgings: (1) nominal pressure PN acuity 10.0 MPaflange kugadzira;(2) chromium-molybdenumforgings dzesimbiine simba rezita PN> 4.0MPa; (3) ferriticforgings dzesimbiine zita rekumanikidza PN> 1.6MPa uye tembiricha yekushandisa ≤-20 ℃.

Buttwelding nemutsipa, flat welding nemutsipa, socket weldinguyethreaded flangekazhinji anogadzirwa nefodya kanaforging rollingprocess.Kana simbi ndiro kana chikamu simbi inoshandiswa, zvinotevera zvinodiwa zvinofanira kusangana:
1.Iyo ndiro yesimbi ichaongororwa ne ultrasonic isina stratification defect;
2.Ngachichekwe kuita mitsara inotenderedza simbi, uye yobatanidzwa kuita mhete nekukotama, uye kuita pamusoro pesimbi iite humburumbira remhete.flanges nemitsipa;
3.Kupinda kwakazara weld kuchagamuchirwa kune butt weld yemhete;
4.Iyo butt weld yerin'i ichaitwa post-weld kupisa kurapwa uye kuita 100% X-ray kana ultrasonic chikanganiso chekuonekwa, uye X-ray yekuona kukanganisa kuchasangana neClass II zvinodiwa zveJB4730 uye iyo ultrasonic kukanganiswa kwekuona kuchasangana nekirasi I. zvinodiwa zveJB4730.
