Mubvunzo 5: Pamapaipi eCO₂ ane pressure yakakwira (1500 psi, 80°C), musanganiswa upi wamunokurudzira?
A:API 5L X65 rutsigiro(nesimba) +Chifukidziro che316L 2.5-3.0 mm(yekubvumidza ngura). Iyi imhinduro yegesi inotapira inoshandiswa zvakanyanya kuMiddle East neNorth America.

Mubvunzo wechitanhatu: Ndeupi musiyano uripo pakati peSA-106 Gr.B neSA-210 Gr.C yepombi dzakaputirwa?
A: SA-210 Gr.C ine simba rekudhonza rakakwira (485 MPa vs 415 MPa) uye yakagadzirirwa machubhu ebhoyira. SA-106 Gr.B ndeyemapombi ekupisa kwakanyanya. Pakushandisa mabhoyira, shandisa SA-210; pamitsetse yekuchinjisa yekuchenesa, SA 106 inogamuchirwa.

Mubvunzo 7: Ndingawana here zvitupa zveEN 10204 Type 3.2 zvemapaipi aya akavharika?
A: Ehe. Tinoshanda neTÜV, BV, DNV, SGS, uye ABS. Mari yekuwedzera inoshanda uye nguva yekutungamira inowedzera nevhiki imwe kusvika mbiri.

Mubvunzo wechisere: Chisungo chiri pakati pe316L nesimbi yekabhoni chinogona kukanganiswa nehydrogen here?
A: Mubasa reCO₂ rinotapira (risina cathodic protection over-voltage), kwete. Mubasa resour (H₂S), bond interface haisi nzira yekupwanya yakanakira kana yakagadzirwa nemazvo. Zvisinei, 316L pachayo ine miganhu yekuomarara. Kune H₂S yakakwira, tinokurudzira nickel alloy clad.

Mubvunzo 9: Ukuru hwe cladding hunosvika 316L hwamunokurudzira ndehupi?
A: 1.5 mm ndiyo diki pane dzose dzinoshandiswa pakusunga uye kupatsanura ngura. Kuti CO₂ ishande zvine simba uye nekukurumidza kuyerera, tinokurudzira 2.5-3.0 mm.

Mubvunzo 10: Munogona here kupa mapaipi aya akaputirwa muchimiro cheU-bent kune vanochinja kupisa?
A: Ehe, kune pombi isina musono (OD ≤168 mm). Tinoita kukotama kunotonhora ne mandrel, tobva taita kurapwa kwekupisa kunorerutsa kushushikana uye 100% NDT yenzvimbo yakakotama. Ndapota kumbira mutengo wakasiyana weU-bend.

Mubvunzo 11: Munopa "chishandiso chekusarudza mapaipi akavharika" chesimbi dzakasiyana-siyana dzinotsigira here?
A: Hongu. Titumirei mamiriro ebasa renyu: tembiricha yepamusoro, tembiricha shoma, kumanikidzwa, kuumbwa kwemvura (CO₂, H₂S, chlorides, pH). Tinokurudzira simbi yekuseri + ukobvu hwecladding + mwero wekuongorora wakakodzera.

Mubvunzo 12: Pane musiyano mukuru wemutengo pakati pechubhu yeSA-210+316L nechubhu ye316L yakasimba here?
A: Ehe. Pachubhu yemadziro ye63.5mm OD × 5mm, yakasimba 316L inenge iri padanho reKudhura kwakapetwa kaviri nehafu kana katatukupfuura pombi yakaputirwa yeSA-210+316L (2mm cladding). Kana madziro akakora, kuchengetedza kwacho kwakakura.

Mubvunzo 13: Sei ndingasarudza pombi isina musono pane yakasungirirwa yakaputirwa?
A: Pombi isina musono inobvisachero musono we weld weld weld, izvo zvinobatsira pakushanda kwecyclic tembiricha yepamusoro, kushanda kwehydrogen, uye kana paine njodzi yekuti chloride SCC irwise weld. Pamashandisirwo mazhinji emapombi emutsetse (X65+316L), pombi dzakasungirirwa dzakasimba dzakavimbika uye dzinodhura zvishoma.

Mubvunzo 14: Unogona kupfeka ID neOD here?
A: Tinogona, asi izvozvo zvine basa guru. Kazhinji CRA layer imwe chete paID yakakwana. Kana paine ngura yekunze, tinokurudzira pendi, coating, kana nzira yakasiyana yekuvhara kunze (semuenzaniso, weld overlay). Ndapota bvunzai nezve dual-clad.

Mubvunzo 15: Ndingaraira sei musanganiswa wakasanganiswa wesimbi dzinotsigira?
A: Ipai chinhu chemutsetse chega chega: giredhi resimbi yekumashure, OD, core WT, ukobvu hwecladding, kureba, huwandu. Tichataura pamubatanidzwa wega wega. Odha shoma yekuedza yehukuru humwe inogamuchirwa.

Mubvunzo 16: Kuisa 316L cladding kunodiwa here?
A: Ehe. Kuisa simbi kunobvisa chiyero chekupisa chinoumbwa panguva yekubvisa nekupisa, kunogadzirisa pasi pechinhu, uye kunoita kuti nzvimbo yacho ive yakachena kuti iongororwe. Kuendesa kwedu kwakajairika kunoiswa muhari uye kunoiswa muhari. Kana musingade kuisirwa simbi (semuenzaniso, yekuisirwa simbi ipapo ipapo), ndapota taurai.

Mubvunzo 17: Munopa PMI (Positive Material Identification) pa316L cladding here?
A: Ehe. Tinogona kuita XRF panzvimbo dzakasiyana-siyana pachubhu yega yega, uye toisa mushumo wacho mufaira remhando yepamusoro. Pane muripo mudiki pachubhu yega yega yekutenga zvinhu zvikuru.

Mubvunzo 18: Pombi yakaputirwa inogona kupihwa magumo akachekwa uye CRA bota here?
A: Hongu. Kona ye bevel yakajairika 30-35° ine 1.6 mm yekumhara. CRA buttering (2-3 mm yeAlloy 625 kana 316L filler pachiso che bevel) inowanikwa kudzivirira kusanganiswa kwemvura panguva yekusveta. Izvi zvinokurudzirwa zvikuru kune ma weld e girth ari kushanda ne high pressure.

Mubvunzo 19: Chii chaunowana pakupa mapaipi e316L akavharwa zvinoenderana nezvinodiwa neEuropean EN?
A: Tinogara tichipa EN 10216-2 (backing) cladding ye1.4404 (316L). Tinogona kupa EN 10204 3.2 certificates neTÜV witness nePED declaration. Maodha mazhinji aenda kuGermany, Netherlands, France, neUK.

Mubvunzo 20: Mungagovana here zvirevo zvepombi yakavharirwa ine dhayamita hombe ye316L (API 5L X65+316L)?
A: Ehe, takapa pombi yeX65+316L clad (OD 610mm, cladding 2.5mm) yepurojekiti yekuisa CO₂ yekuMiddle East (200 km pombi). Mareferensi anowanikwa paNDA.

Kuti uve nechokwadi chekuti wawana musanganiswa wakakodzera, ndapota ipa zvinotevera kune chinhu chimwe nechimwe chemutsetse:

1. Giredhi resimbi rinotsigirwa(sarudza kubva kuSA-210 Gr.C, SA-106 Gr.B, API 5L X52/60/65, A333 Gr.6, A335 P11/P22)

2. Dhayamita yekunze (OD)uyeukobvu hwemadziro epakati

3. 316L ukobvu hwekufukidza(kazhinji 1.5-3.5 mm)

4. Kureba kumwe chete(m) uye hurefu hwese (kana huwandu)

5. Muyero unoshanda(ASME, API, EN, kana tsanangudzo yepurojekiti)

6. Chitupa chinodiwa(EN 10204 Rudzi rwe3.1 standard; Rudzi rwe3.2 sarudzo)

7. Miedzo yekuwedzera(Charpy, ngura yepakati pegranular, NACE, creep, nezvimwewo)

8. Kupedzisa kupedzisa(isina kupfava, yakachekwa, yakachekwa + ichiwedzera mafuta)

9. Nguva yekutumira(FOB China port, CIF destination port, Air shipping)

10. Womic Steel ichapindura ne:

● Pepa reruzivo rwehunyanzvi rwemusanganiswa chaiwo

● Kotesheni ine mutengo nenguva yekuunza

● Chitupa chemuenzaniso wemugayo (kubva pane zvakamboitwa kare zvakafanana)

● Hurongwa hwemhando yepamusoro hwakarongwa uye nzvimbo yekuongorora

Simba redu:Hatingogadziri chete asiworayirapamubatanidzwa wesimbi inochengetedza mari uye yakavimbika + cladding yemamiriro ebasa rako. Vatengi vazhinji vanonyanya kutsanangura nekufungidzira kuti alloy yakasimba inodiwa - tinovabatsira kuchengetedza 40-60% nepaipi inovhara.
