1. Sei Uchifanira Kusarudza Pombi Yakaputirwa - Uye Sei Uchifanira Kugadzira Simbi Yesimbi?
Pombi yakaputirwa inosanganisasimbi ine simba guru kana kuti simbi ine alloy yakaderera(inobata kumanikidzwa, mutoro wemakanika, uye mutengo) nerukoko rwemukati runodzivirira ngura(inobata zvakananga mvura inodziya). Chimiro ichi chine mativi maviri chinoderedza mutengo wezvinhu ne30–60% zvichienzaniswa nepombi yakasimba yeCRA, ukuwo ichipa dziviriro yakaenzana yengura uye hupenyu hwebasa.
Semunhumugadziri wemapaipi akapfeka, Womic Steel haingope chete katarogu yezvinhu. Tinotanga nemamiriro ekushanda kwako: H₂S, CO₂, Cl⁻, pH, tembiricha, kumanikidzwa, hydrogen partial pressure, uye zvinodiwa zvemakanika. Zvadaro tinokurudzira musanganiswa wakavimbika uye usingadhuri wesimbi yekumashure, CRA cladding, uye maitiro ekubatanidza.
Ruzivo rwedu runobva mumapurojekiti chaiwo - minda yegesi inonaka iri mugungwa, migero yemvura yakadzika pasi pegungwa, mabhoyira emagetsi anonyanya kukosha, mitsetse yehydrogen pilot, uye masisitimu ekuisa CCUS-EOR. Tinonzwisisa kuti pombi yakavharirwa haisi chinhu; chigadzirwa chakagadzirwa nemainjiniya.
2. Maitiro Ekubatanidza Simbi - Maitiro Atinoita Kubatanidza Simbi Mbiri
Chinhu chinokosha pakugadzira pombi yakavimbika ine jira rakavharwa ndichonzira yekubatanidzapakati pesimbi inotsigirwa neCRA layer. Pazasi pane maitiro mana makuru atinoshandisa, akarongwa zvichienderana nesimba remabhondi uye kukodzera kwekushandisa.
2.1 Kukanda kweCentrifugal + Kupisa Kunobuda (Seamless Metallurgical Bond)
Mashandiro azvinoita:
Chigadziko cheCRA chinotanga chakandwa muchubhu isina chinhu ine gomba. Chubhu iyi inozopinzwa muchubhu yesimbi yekabhoni, yodziiswa, uye yoburitswa pamwe chete kuburikidza nemuchina mukuru wekubudisa. Pakupisa kwakanyanya uye kumanikidzwa, simbi mbiri idzi dzinopararira, dzichiita chisungo chechokwadi chesimbi.
Hunhu hwechisungo:
● Simba rekuchekerera reinterface ≥300 MPa (yakanyanya kupfuura mamwe ese maitiro)
● Hapana musono we weld weld kwenguva refu - usina musono zvachose
● Ukobvu hwekuvhara hunoenderana, zviyero zvakananga
Zvakanakira:
Diki kusvika pakati nepakati (≤400mm – ~16″), kumanikidzwa kwakanyanya, kupisa kwakanyanya, hydrogen service, machubhu ebhoyira, machubhu epasi, heat exchanger U-bends.
2.2 Kubatanidza Kunopisa + JCOE / UOE
Mashandiro azvinoita:
Pureti yeCRA nepureti yesimbi yekabhoni zvinocheneswa, zvoiswa mu vacuum, zvovharwa, zvodziiswa, zvopfuudzwa nemuchina unotenderera. Mapuritsi akawanda anotenderera anogadzira chisungo chesimbi. Pureti inovhara inozogadzirwa kuita pombi uchishandisa JCOE (JCO-Edge) kana UOE press forming, zvichiteverwa ne longitudinal seam welding.
Hunhu hwechisungo:
● Simba rekuchekerera reinterface 200–260 MPa
● Zvinokwanisika kuva nedhayamita yakakura kwazvo (kusvika 1,800mm / 72″)
● Hurefu hwakareba hwemunhu mumwe chete (kusvika 24m kana kupfuura)
● Ine musono mumwe chete weld weld (inofanira kunge yakanyatsokodzera uye NDT yakaongororwa)
Zvakanakira:
Mapaipi emhando ye "long dayamita" makuru, "deep water subsea flow lines", "trunk lines", "risers". Iyi ndiyo nzira inonyanya kushandiswa pakugadzira mapaipi e "clad line" ane chitupa cheAPI 5LD.
2.3 Kuputira Kuvhara + Kutenderedza Mapureti
Mashandiro azvinoita:
Purati yeCRA inoiswa pamusoro pepurati yesimbi yekabhoni ine mukaha wakarongwa, yozofukidzwa nezvinhu zvinoputika. Kuputika uku kunoisa purati yeCRA mupurati yekumashure nekukurumidza, zvichiita kuti pave nechisungo chakasimba. Purati yakaputirwa inozopetwa yobatanidzwa mupombi.
Hunhu hwechisungo:
● Chinopindirana chine mafungu chine simba rakanaka kwazvo rekubatanidza (200–280 MPa)
● Inogona kubatanidza simbi dzakasiyana dzakaoma kutenderedza-kubatanidza (semuenzaniso, titanium kusimbi, zirconium kusimbi)
● Saizi yeplate inoganhurirwa nechinhu chinoputika; kusungirirwa kunotevera kunodiwa
Zvakanakira:
Misanganiswa yemhando dzakasiyana dzemachira: titanium/simbi, zirconium/simbi, tantalum/simbi yekuisa mapaipi emakemikari ane simba uye zvinochinja-chinja kupisa.
2.4 Kuisa Micheka Yemuchina (Hazvikurudzirwi Pabasa Rinokosha)
Mashandiro azvinoita:
Chubhu yeCRA liner inowedzerwa nekutonhora kana kuti inowedzerwa ne hydraulic mukati mepombi yesimbi yekabhoni. Zvikamu zviviri izvi zvinogara pamwe chete nekupindirana (hoop stress).
Hunhu hwechisungo:
●Hapana chisungo chesimbi- kungobatwa panyama chete
● Simba rekubatanidza <10 MPa
● Mucheka unogona kumonana, kuputsika, kana kuputsika kana kupisa kuchikwira kana kumanikidzwa kuchikwira
Patinoshandisa:
Kungoshandiswa chete pakupisa kwakaderera, kumanikidzwa kwakaderera, kusingatenderere, uye kana mutengi achibvuma pachena miganhu yacho. Tinogara tichitsanangura njodzi dziripo kana tichienzanisa nepombi dzakasungirirwa nesimbi.
Kurudziro yedu:Kune chero basa rinokosha remafuta negesi, hydrogen, kana mvura yakadzika, sarudza pombi dzakaputirwa nesimbi - kwete pombi dzakaputirwa nekanika.
3. Gwaro Rekusarudza Maitiro - Kurumidza Kutsvaga
