P235GH ST35.8 SA192 Simbi yeKabhoni Pombi Isina Musono / Tubhu yeBhoira

Mharidzo yechigadzirwa

Hunhu hwemuchina hwepaipi yeboira chiratidzo chakakosha chekuona kuti simbi inoshanda sei (hunhu hwemuchina), zvinoenderana nemakemikari akagadzirwa uye sisitimu yekurapa kupisa yesimbi. Muchiyero chepaipi yesimbi, zvinoenderana nezvinodiwa zvakasiyana zvekushandisa, taura mashandiro ekudhonza (simba rekudhonza, simba rekudhonza kana nzvimbo yekudhonza, kureba), pamwe nezviratidzo zvekuomarara nekusimba, pamwe nekushanda kwekupisa kwakanyanya uye kwakaderera kunodiwa nevashandisi.
① Tembiricha yekushandisa yepombi yebhoyira iri pasi pe350℃, uye pombi yemumba inonyanya kugadzirwa ne10 ne20 carbon junction steel hot rolled pipe kana cold pull pipe. Nyika dzekunze dzinonyanya kushandisa P235GH, SA192, ST35.8,106B, 210A1,210C.
② Pombi yebhoyira ine simba guru inowanzo shandiswa mumamiriro ekupisa kwakanyanya uye ekumanikidzwa kwakanyanya, pombi iri pasi pesimba remhepo inopisa uye utsi hwemvura, oxidation uye ngura zvinoitika. Pombi yesimbi inodiwa ine simba rakasimba, inodzivirira oxidation uye ngura zvakanyanya, uye ine kugadzikana kwakanaka kwenyama.
Pombi yeboira inonyanya kushandiswa kugadzira pombi dzemvura, pombi dzemvura dziri kufashaira, pombi dzemhepo dzinopisa zvakanyanya, pombi dzemhepo dzinopisa zvakanyanya dzeboira remota, pombi dzeutsi hombe nediki uye pombi dzezvidhinha zvearch, nezvimwewo.

Nzira yekuongorora mhando yepombi yesimbi isina musono

1. Kuongorora kuumbwa kwemakemikari: nzira yekuongorora makemikari, kuongorora kwemidziyo (infrared CS instrument, direct reading spectrometer, zcP, nezvimwewo).
2. Kuongororwa kwemhando yepamusoro yepombi yesimbi: 100%
A. Kuonekwa kweUltrasonic UT:
B. ET: (kupinza kwemagetsi)
C. MT uye kuonekwa kwekubuda kwemvura:
Kuona zvikanganiso zvemagineti, zvakakodzera kuona zvikanganiso zvepamusoro nepedyo pezvinhu zve ferromagnetic.
D. Kuonekwa kwezvikanganiso zve electromagnetic ultrasonic:
Hapana nzira yekubatanidza inodiwa, iyo inogona kuiswa pakuona zvikanganiso pamusoro pepombi yesimbi inodziya zvakanyanya uye inomhanya zvakanyanya, yakaoma uye yakaoma.
Kuedzwa kwekupinda mumvura muE.:
Kupenya, kupenda, uye kuona zvikanganiso pamusoro pepombi yesimbi.
3. Kuongororwa kwepombi yesimbi nemakemikari mumuviri;
4. Kuongororwa kwekushanda kwepombi yesimbi:
① Bvunzo yakati sandara: sampuro yakatenderera yemuenzaniso wakaita seC (S / D & gt; 0.15) H= (1 + 2) S / (+ S / D)
L=40~100mm pahurefu hweyuniti imwe neimwe deformation coefficient =0.07~0.08
② Kuedza kudhonza: L=15mm isina mutswe inokodzera
③ Kuedza kuwedzera nekukombama: tembiricha yepamusoro ndeye 30°, 40° uye 60°
④ Bvunzo yekukombama: inogona kutsiva bvunzo yekutatamura (yepombi hombe ine dhayamita).
