ʻO ke kinoea ʻawaʻawa pulu - aia ka hydrogen sulfide (H₂S), carbon dioxide (CO₂), a me nā chloride pinepine - kekahi o nā wahi ʻino loa no nā paipu kila kalapona. Hoʻopau koke ke kila X65 maʻamau ma muli oka haki ʻana o ke kaumaha sulfide (SSC)a meka haki ʻana o ka hydrogen (HIC).

Paipu ʻaʻahu bimetal X65MS+Incoloy 825ua hoʻolālā kūikawā ʻia no ia mau kūlana:

● Ke kila kākoʻo X65MS wahohe mana hoʻololi ʻia o X65 me ka lawelawe ʻawaʻawa. He haʻahaʻa kona kalapona (≤0.10%), haʻahaʻa ka sulfur (≤0.002%), a me ka paʻakikī i kāohi ʻia (≤248 HV) e kūʻē iā SSC a me HIC e like me ka mea i koi ʻia e NACE MR0175 / ISO 15156.

●ʻO ka uhi ʻana o loko o Incoloy 825 (UNS N08825)he mea hoʻohuihui nickel ia e loaʻa ana he 38-46% Ni, 19-23% Cr, 2.5-3.5% Mo, me ke keleawe a me ka titanium. Kūpaʻa ia i ka H₂S, CO₂, nā chlorides kiʻekiʻe, ka sulfur elemental, a me nā waikawa organik ma kahi pH ākea a me ka pae mahana.

8. Nā Nīnau i Nīnau Pinepine ʻia (FAQ)

Q1: He aha ka ʻokoʻa ma waena o X65 a me X65MS?
A: He hoʻololi "lawelawe ʻawaʻawa" ʻo X65MS o X65. Loaʻa iā ia ka kalapona haʻahaʻa (≤0.10%), ka sulfur haʻahaʻa loa (≤0.002%), ka mana paʻakikī paʻa (≤248 HV), a me ka hoʻāʻo SSC/HIC i koi ʻia e like me NACE MR0175. ʻAʻole kūpono ka X65 maʻamau no ka H₂S pulu.

Q2: No ke aha e hoʻohana ai iā Incoloy 825 ma kahi o 316L a i ʻole duplex no ka lawelawe ʻawaʻawa?
A: Loaʻa i ka Incoloy 825 ka nickel kiʻekiʻe (38-46%), kahi e hāʻawi ai i ke kū'ē maikaʻi loa i ka SCC a me SSC i hoʻokomo ʻia e ka chloride. Kū'ē pū ia i nā waikawa hoʻemi (e laʻa, HCl) a me ka sulfur elemental - nā kūlana kahi e hāʻule ai ka 316L a me ka duplex. No ka lawelawe ʻawaʻawa koʻikoʻi loa (H₂S kiʻekiʻe + chlorides kiʻekiʻe + elemental S), ʻo Incoloy 825 ka CRA haʻahaʻa loa i ʻae ʻia.

Q3: Hiki ke hoʻopili ʻia ka ʻili Incoloy 825 iā ia iho a i ʻole i ke kila kalapona?
A: ʻAe. Hiki ke hoʻoheheʻe ʻia ʻo Incoloy 825 e GTAW (TIG), GMAW (MIG), a me SMAW. No ka hoʻohui ʻana i ka cladding i ka cladding, e hoʻohana i ka metala hoʻopihapiha Alloy 82 / 82i (ERNiCr-3) a i ʻole Alloy 625 (ERNiCrMo-3). No ka hoʻohui ʻana i ka cladding i ke kila kalapona (e laʻa, ka uhi weld), e hoʻohana i kahi papa waena o Alloy 309L a i ʻole 625 e pale aku i ka dilution a me ka haki ʻana.

Q4: Ua kūpaʻa anei ka wili longitudinal seam i ka lawelawe ʻawaʻawa?
A: ʻAe. Hoʻopili ʻia ka ʻaoʻao o loko me ka mea hoʻopihapiha Incoloy 625 (ʻoi aku ka kiʻekiʻe o ka Ni, Cr, Mo ma mua o 825). Hāʻawi kēia uhi hoʻopili i ka pale ʻana i ka palaho like a ʻoi aku paha ma mua o ka uhi 825. Ua nānā ʻia ka hoʻopili holoʻokoʻa me 100% NDT a ua hoʻāʻo ʻia ka paʻakikī.

Q5: He aha nā palapala hōʻoia i hāʻawi ʻia no ka lawelawe ʻawaʻawa?
A: Hoʻopuka mākou i nā palapala hōʻoia EN 10204 Type 3.1/3.2 e komo pū ana me ka loiloi wela o ke kila kākoʻo, ka paʻakikī, nā hōʻike hoʻāʻo SSC a me HIC (inā hana ʻia), a me ka ana ʻana o ka paʻakikī weld. Ma ke noi ʻana, hāʻawi mākou i kahi leka hoʻokō NACE MR0175.

Q6: He aha ka manawa alakaʻi maʻamau no ka paipu ʻaʻahu X65MS + Incoloy 825?
A: Kauoha mua: 14-18 pule (e komo pū ana me ke kūʻai ʻana i nā mea lawelawe ʻawaʻawa a me ka hōʻoia). Nā kauoha hou: 10-12 pule. Hiki i ka nānā ʻana o ke kolu o ka ʻaoʻao ke hoʻohui i 1-2 pule.

Q7: Hiki iā Womic Steel ke hoʻolako i ka paipu Inconel 625 ma kahi o Incoloy 825?
A: ʻAe. No nā kūlana ʻoi aku ka paʻakikī (wela kiʻekiʻe, H₂S kiʻekiʻe, chlorides kiʻekiʻe), hāʻawi mākou i ka paipu i uhi ʻia me X65MS+Inconel 625 (UNS N06625). ʻOi aku ka ikaika o Inconel 625 a ʻoi aku ka maikaʻi o ke kū'ē ʻana i ka pitting (PREN >45). E kelepona mai iā mākou no kahi ʻikepili ʻokoʻa.
