Mhedzisiro yeHydrogen Sulfide pane Equipment

Wet hydrogen sulfide sevhisi kukuvadzwa kunowanzoonekwa mu kabhoni uye yakaderera alloy simbi midziyo iri mukati mezvivakwa zvinogadzira mahydrocarbons, akadai semafuta negasi, makemikari, uye petrochemical maindasitiri. Assets ari munzvimbo ine aqueous sour environment inosanganisa H2S content yakakura kudarika 50 ppm uye tembiricha iri pasi pe82° C (180° F) inonyanya kukanganiswa nekunyorova kweH2S. Masimbi ekare kana "akasviba" anowanzo kunyorova kukuvadzwa kweH2S nekuti anowanzo kuve neakawanda volumetric inclusions, laminations, uye yepakutanga kugadzirwa kusakwana munzvimbo dzese dzesimbi uye weld deposit. Kukuvara kweH2S kwakanyorova kunoonekwa zvakanyanya mumabhomba emidziyo yekumanikidza, matangi, kana zvikamu zvakakura dhayamita yakareba seam-welded piping zvikamu pane zvakajairwa seamless pombi, tubing, kana forgings.

Muhupo hwehunyoro, H2S inodyidzana nesimbi yemudhuri wesimbi inoburitsa haidrojeni murukova rweoiri. Iyo haidhirojeni inopararira musimbi, ichibatana kuita molecular hydrogen pa discontinuities. Nekufamba kwenguva, yakawanda uye yakawanda haidrojeni inobatwa ichivaka kudzvanywa nokudaro kushushikana musimbi kunotungamira mukukundikana kwenzvimbo. Heano mamwe emhando dzakasiyana-siyana dzinogona kuonekwa:

• Kushushikana kunokonzera kutsemuka kunowanzoita laminar uye kutariswa kunoenderana nemukati nekunze kwechikamu chechikamu. Nekufamba kwenguva, mitswe iyi inowanzobatana nekuda kwekumanikidza kwemukati kuvaka-up uye pamwe nzvimbo dzekushushikana kwenzvimbo munzvimbo dzakakuvadzwa dzinopararira kuburikidza nekukora kwechikamu. Izvi zvinozivikanwa seHydrogen Induced Cracking (HIC) kana kutsemuka nhanho.
• Kana iyo lamination ikaitika pedyo nechepamusoro, tinogona kuguma ne blister inokwira kubva mukati, kunze kwepamusoro, kana mukati memadziro emadziro emidziyo yekumanikidza. Pamusoro pezvo, kutsemuka kunogona kusimuka kubva kunharaunda yeblister, zvichigona kupararira munzira-yemadziro, kunyanya pedyo nevelds.
• Stress Oriented Hydrogen Induced Cracking (SOHIC) inoratidzika semitsetse yezvimedu zvakaturikidzana pamusoro peumwe neumwe zvichikonzera kutsemuka kwepakati-kutenderedza simbi yepasi padhuze neiyo Heat Affected Zone (HAZ).

Kana zvasvika kune Non-Destructive Testing (NDT) nzira, yakajairika Ultrasonic Testing (UT) yakashandiswa zvakanyanya uchishandisa yakajairika chiitiko uye shear wave probes. Izvo zvine, zvisinei, zvinonetsa kusiyanisa pakati pelamination / inclusions kubva mu-sevhisi kukuvara. Iyo zvakare inonetsa uye inononoka maitiro ayo anotsamira zvakanyanya mushandisi.

Iyo itsva hydrogen sulfide inopikisa composite (fiberglass) bhiriji plug rakagadzirwa uye rakagadziriswa neVigor's R&D department rakawana zvinogutsa murabhoritari uye panzvimbo yemutengi, uye Vigor's tekinoroji timu inogona ikozvino kugadzira nekuigadzira zvinoenderana nezvinodiwa nemutengi kusangana nemutengi. pane-saiti zvinodiwa. Kana iwe uchifarira Vigor's bhiriji plug zvigadzirwa, ndapota usazeza kubata neboka reVigor kune zvigadzirwa zvakagadziridzwa uye akasarudzika emhando masevhisi.
