1. Pfupiso - Nei X65MS+Incoloy 825 yeSour Service

Gasi rakanyorova rine hydrogen sulfide (H₂S), carbon dioxide (CO₂), uye kazhinji ma chloride - ndeimwe yenzvimbo dzinonyanya kukonzera kuputika kwemapaipi esimbi yekabhoni. Simbi yemhando yeX65 inokundikana nekukurumidza nekuda kwekupwanya kushushikana kwesulfide (SSC)uyekutsemuka kunokonzerwa nehydrogen (HIC).

X65MS+Incoloy 825 bimetal clad pombiyakagadzirirwa zvakananga mamiriro ezvinhu akadaro:

● Simbi yekunze yeX65MS inotsigiraimhando yeX65 yakagadziriswa nesour-service. Ine kabhoni shoma (≤0.10%), sarufa shoma (≤0.002%), uye kuomarara kwayo (≤248 HV) kudzivirira SSC neHIC sezvinodiwa neNACE MR0175 / ISO 15156.

●Chifukidziro chemukati cheIncoloy 825 (UNS N08825)isimbi yakagadzirwa ne nickel ine 38-46% Ni, 19-23% Cr, 2.5-3.5% Mo, pamwe nemhangura ne titanium. Inokwanisa kutsungirira H₂S, CO₂, ma chloride akawanda, elemental salfa, uye organic acids pa pH yakakura uye tembiricha.

Matinji maviri aya anobatanidzwa zvachose nechisungo chesimbi (hot roll bonding + JCOE forming). Kusiyana nepombi dzakagadzirwa nemakanika, panehapana njodzi yekudonha kwemuchina, kuunyana, kana ngura panzvimbo inopindirana.

4. Maitiro Ekugadzira - Hot Roll Bonding + JCOE

Maitiro ekugadzira pombi yeX65MS+Incoloy 825 anonyatsotevedzera vimbiso yemhando yebasa rakakora:

●Kusarudzwa kwezvinhu & kusimbiswa– Plate yeX65MS neplate yeIncoloy 825 zvinobva mumigodhi inotenderwa. Kemikari yeOES nekuoma kwayo zvakasimbiswa.

● Kugadzirira pamusoro– Maplate ese ari maviri anocheneswa uye anokuyiwa kuti abvise makwande ne oxide.

● Kuisa muchina wekuchenesa– Maplate akarongwa (Incoloy 825 mukati), mipendero yakavharwa pasi pevacuum (≤10 Pa) kudzivirira oxidation panguva yekupisa.

● Kupisa kutenderedza– Stack inopisa kusvika 1180-1250°C, yakakungurutswa nechiyero chepamusoro chekudzikisa (≥5:1). Chisungo chesimbi chinoumbwa nekupararira kweatomu.

● Kuongorora ndiro dzakaputirwa- Kuongororwa kwe100% kwe ultrasonic kuti uone kuti bond inoenderana nehukuru hwayo.

● Kuumbwa kweJCOE– Purati yakagayiwa nemucheto ine nhanho, yozogadzirwa kuita pombi yakavhurika kuburikidza neJCO presses.

● Kusonwa kwemusono werefu– Nzira yekubatanidza weld yemukati ine Incoloy 625 filler; nzira dzekunze dzine low carbon steel filler. Maitiro ekushongedza weld akakodzera NACE/API 5LD.

● Kufukidza jira rekunamira (kufukidza kwakasarudzwa)– Musono wemukati we weld unogona kuputirwa neIncoloy 625 kuti urambe uchidzivirira ngura zvakanyanya.

● Kurapa kupisa- Kurerutsira kushushikana (PWHT) kana zvichidikanwa nekodhi yekugadzira; zvikasadaro hapana kurapwa kwekupisa kuchengetedza hunhu hwesimbi inonyunguduka.

● NDT & bvunzo– Ona Chikamu 5.

● Pedzisa kupedzisa– Migumo yeBevel + mafuta anodzivirira ngura + zvivharo zvepurasitiki.

8. Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)

Mubvunzo 1: Musiyano uripo pakati peX65 neX65MS ndeupi?
A: X65MS ishanduro ye "sour service" yeX65. Ine kabhoni yakaderera (≤0.10%), sarufa yakaderera kwazvo (≤0.002%), kudzora kuomarara kwakasimba (≤248 HV), uye kuyedzwa kweSSC/HIC kunosungirwa paNACE MR0175. Standard X65 haina kukodzera H₂S yakanyorova.

Mubvunzo wechipiri: Sei uchishandisa Incoloy 825 pachinzvimbo che316L kana duplex pakugadzira sour service?
A: Incoloy 825 ine nickel yakawanda (38-46%), iyo inopa kusimba kwakanaka kuSCC neSSC zvinokonzerwa nechloride. Inodzivirirawo kuderedza acids (semuenzaniso, HCl) uye elemental salfa - mamiriro ezvinhu apo 316L neduplex zvinokundikana. Kune sour service yakanyanya (H₂S yakawanda + chlorides yakawanda + elemental S), Incoloy 825 inowanzova CRA inogamuchirwa zvishoma.

Mubvunzo wechitatu: Ko Incoloy 825 cladding inogona kusungirirwa pachayo here kana kuti kusimbi yekabhoni?
A: Ehe. Incoloy 825 inogona kusungirirwa neGTAW (TIG), GMAW (MIG), uye SMAW. Pakubatanidza cladding necladding, shandisa filler metal Alloy 82 / 82i (ERNiCr-3) kana Alloy 625 (ERNiCrMo-3). Pakubatanidza cladding necarbon steel (semuenzaniso, weld overlay), shandisai intermediate layer yeAlloy 309L kana 625 kudzivirira kusanganiswa uye kutsemuka.

Mubvunzo wechina: Ko welding yemusono we longitudinal inodzivirirawo here?
A: Ehe. Kupinda kwemukati kwakasungirirwa neIncoloy 625 filler (yakakwirira Ni, Cr, Mo pane 825). Iyi weld overlay inopa kudzivirira ngura kwakaenzana kana kuri nani pane 825 cladding. Weld yese yakaongororwa 100% NDT uye kuomarara kwakaedzwa.

Q5: Ndezvipi zvitupa zvinopihwa sevhisi yesour?
A: Tinoburitsa zvitupa zveEN 10204 Type 3.1/3.2 zvinosanganisira kuongorora kupisa kwesimbi, kuomarara, mishumo yekuyedza yeSSC neHIC (kana yakaitwa), uye ongororo yesimba reweld. Kana takumbira, tinopa tsamba yekutevedzera mitemo yeNACE MR0175.

Mubvunzo 6: Ndeipi nguva yakajairika yekupa pombi yeX65MS+Incoloy 825?
A: Odha yekutanga: mavhiki 14-18 (inosanganisira kutenga zvinhu zvebasa rakaoma uye kufanirwa). Kudzokorora odha: mavhiki 10-12. Kuongorora kwevamwe vanhu kunogona kuwedzera vhiki 1-2.

Mubvunzo wechinomwe: Ko Womic Steel inogona kupa pombi dzakaputirwa dzeInconel 625 panzvimbo peIncoloy 825 here?
A: Hongu. Kune mamwe mamiriro ezvinhu akaoma (tembiricha yakakwira, H₂S yakakwira, machloride akawandisa), tinopa pombi dzakavharirwa dzeX65MS+Inconel 625 (UNS N06625). Inconel 625 ine simba rakawanda uye inodzivirira makomba zviri nani (PREN >45). Tibatei kuti muwane rumwe ruzivo.
