Butt welding flange haisi nyore kukanganisa, yakavharwa zvakanaka, inoshandiswa zvakanyanya, ine inowirirana kusimba uye elasticity zvinodiwa uye zvine musoro butt welding kutetepa shanduko, welding chinhambwe kubva pajoinhi nzvimbo yakakura, iyo yakabatana pamusoro kubva mukupisa tembiricha deformation, zvinotora zvimwe. yakaoma chikosoro chimiro chemuviri, chakakodzera kudzvanywa kana tembiricha kuchinjika kwepombi kana tembiricha yepamusoro, kumanikidza kwakanyanya uye yakaderera tembiricha pombi, Inowanzo shandiswa kuPN yakakura kupfuura 2.5MPa pombi uye yevhavha yekubatanidza;Inoshandiswawo kutakura pombi inodhura, inobvira, inoputika yepakati.
Butt welded flange inowanzogadzirwa nekugadzira kana kugadzira.Kana iyo simbi ndiro kana chikamu simbi inoshandiswa, zvinotevera zvinodiwa zvinofanirwa kusangana:
1.The butt welding flange inofanira kuongororwa ne ultrasonic, pasina delamination defects;
2.Inofanira kuchekwa kuita zvidimbu pamwe chete negwaro resimbi inoputika, yakasungirirwa mumhete kuburikidza nekukotama, uye pamusoro pesimbi kuti iite silinda yemhete.Simbi ndiro haifaniri kugadzirwa zvakananga mumutsipa butt welding flange;
3.The butt weld yemhete inofanira kutora yakazara kupinda weld;
4. Iyo butt weld yemhete ichaitwa post-welding heat treatment, uye ichaiswa pasi pe100% ray kana ultrasonic inspection, iyo inosangana neII zvinodiwa zveJB4730 uye kuongorora kwe ultrasonic kuchasangana neI zvinodiwa zveJB4730.
Kutsetseka kwemutsipa wekunze webutt welding flange haifanire kunge yakakura kupfuura 70 °.Technical parameters yebutt welding flange inodzorwa zvakanyanya panguva yekugadzira uye welding kuti ive nechokwadi chekuti inogona kutamba basa rayo uye kukosha zvizere mukugadzira nekushandisa.
