Q1: He aha ka ʻokoʻa koʻikoʻi ma waena o ka paipu seamless clad i hoʻopaʻa ʻia me ka metallurgically a me ka paipu i hoʻopaʻa ʻia me ka mechanical?
A: I loko o ka paipu i hoʻopaʻa ʻia me ka metallurgically, hoʻokumu ka interface i kahi pilina diffusion atomic-scale (ikaika shear ≥300 MPa). Hoʻopau loa kēia i ka wili ʻana o ka liner, ka hiolo ʻana a i ʻole ka hoʻokaʻawale ʻana, ʻo ia nā pilikia maʻamau no ka paipu i hoʻopaʻa ʻia me ka mechanical ma lalo o ka thermal cycling a i ʻole ka pressure pulsation.

Q2: No ke aha e hoʻohana ai iā T91 (X10CrMoVNb9-1) ma mua o P91 ma ke ʻano he papa waho?
A: Hoʻokahi ka haku mele kemika o T91 a me P91. ʻO T91 ka inoa no ka paipu seamless (hoʻohana ʻia no nā paipu paila liʻiliʻi, e laʻa me nā kūlou superheater), ʻoiai ʻo P91 e hoʻohana ʻia no nā paipu nui. ʻO T91 ke koho kūpono loa no ka hana ʻana i nā kūlou superheater a me nā reheater U.

Q3: He aha ka ʻokoʻa ma waena o UNS N08028 (Alloy 28) a me UNS N08825 (Incoloy 825)?
A: ʻOi aku ka nui o Cr, Mo a me Cu o ka Alloy 28, e hāʻawi ana i ke kū'ē maikaʻi loa i ka sulfuric acid, phosphoric acid a me nā wahi chloride kiʻekiʻe (PREN 38-40). Loaʻa i ka Incoloy 825 ka nickel hou aku, e ʻoi aku ka paʻakikī o ke kū'ē ʻana i ka hoʻemi ʻana i nā waikawa a me ka hydrofluoric acid. ʻOi aku ka maikaʻi o ke kumukūʻai. No ka loiloi waena kikoʻī, e kūkākūkā me ka hui ʻenekinia o Womic Steel.

Q4: Hiki ke hoʻohana ʻia ka paipu i uhi ʻia me ka P265GH + TP304L no ka ʻāpana haʻahaʻa o ka paila?
A: ʻAe. Hāʻawi ʻo P265GH i ka ikaika maikaʻi o ka mahana waena a me ka hiki ke hoʻopili ʻia, ʻoiai ke kūpale ʻana o loko 304L i ka pala mai ka condensate kinoea flue (loaʻa ka waikawa sulfurous). Manaʻo ʻia e sila i nā wēlau o ka paipu ma hope o ka hoʻāʻo hydrostatic e pale aku i ka popo ma mua o ka lawelawe ʻana.

Q5: Hiki iā ʻoe ke hāʻawi i nā palapala hōʻoia EN 10204 Type 3.2 a me ka hōʻike ʻana mai nā ʻaoʻao ʻekolu?
ʻAe. Loaʻa iā Womic Steel ka laulima lōʻihi me SGS, BV, TÜV, DNV, ABS a me LR. Hiki iā mākou ke hoʻonohonoho i ka ʻike ʻana o nā ʻaoʻao ʻekolu i ka hoʻāʻo ʻana (e laʻa, tensile, UT) a hoʻopuka i nā palapala hōʻoia Type 3.2.

Q6: He aha ka manawa hoʻouna maʻamau no kēia mau hui paipu i uhi ʻia?
A: No nā kauoha mua o nā hui maʻamau, ʻo ka lawe ʻana he 60-90 mau lā maʻamau (me ke kūʻai ʻana i nā mea, ka extrusion composite, ka hoʻopau anu a me ka hoʻāʻo ʻana). No nā hui i hana nui ʻia (e laʻa, P265GH+TP304L), hiki ke hoʻemi ʻia ka manawa alakaʻi i 45-60 mau lā.

10. Kāhea iā Womic Steel - ʻO kāu mea hana paipu Clad
