Q1: Qhov txawv tseem ceeb ntawm cov yeeb nkab uas sib txuas ua ke los ntawm cov hlau thiab cov yeeb nkab uas muaj cov khoom siv kho tshuab yog dab tsi?
A: Hauv cov yeeb nkab uas sib txuas nrog hlau, qhov sib txuas ua ke tsim cov atomic-scale diffusion bond (shear strength ≥300 MPa). Qhov no tshem tawm tag nrho cov liner wrinkling, collapse lossis sib cais, uas yog cov kev pheej hmoo rau cov yeeb nkab uas tau sib txuas nrog tshuab hauv qab thermal cycling lossis pressure pulsation.

Q2: Vim li cas ho siv T91 (X10CrMoVNb9-1) es tsis yog P91 ua txheej sab nraud?
A: T91 thiab P91 muaj cov tshuaj sib xyaw ua ke zoo ib yam. T91 yog lub npe rau cov raj tsis muaj qhov (siv rau cov raj me me uas muaj txoj kab uas hla boiler, piv txwv li, cov khoov superheater), thaum P91 yog siv rau cov raj loj uas muaj txoj kab uas hla. T91 yog qhov kev xaiv zoo tshaj plaws rau kev ua cov superheater thiab reheater U-bends.

Q3: Qhov txawv ntawm UNS N08028 (Alloy 28) thiab UNS N08825 (Incoloy 825) yog dab tsi?
A: Alloy 28 muaj Cr, Mo thiab Cu siab dua, muab kev tiv taus zoo dua rau sulfuric acid, phosphoric acid thiab cov chaw muaj chloride ntau (PREN 38-40). Incoloy 825 muaj nickel ntau dua, ua rau nws tiv taus cov kua qaub thiab hydrofluoric acid ntau dua. Nws kuj tseem pheej yig dua. Rau kev tshuaj xyuas tshwj xeeb, sab laj nrog Womic Steel pab pawg engineering.

Q4: Cov yeeb nkab P265GH + TP304L puas siv tau rau qhov kub qis ntawm lub boiler?
A: Yog. P265GH muaj lub zog kub nruab nrab thiab weldability, thaum lub 304L sab hauv cladding tiv taus xeb los ntawm flue gas condensate (muaj sulfurous acid). Nws raug pom zoo kom kaw lub raj kawg tom qab hydrostatic xeem kom tiv thaiv kev ua ntej kev pabcuam xeb.

Q5: Koj puas muab tau daim ntawv pov thawj EN 10204 Hom 3.2 thiab cov neeg ua tim khawv thib peb?
A: Yog. Womic Steel muaj kev koom tes ntev nrog SGS, BV, TÜV, DNV, ABS thiab LR. Peb tuaj yeem npaj cov neeg sab nraud los ua pov thawj rau kev sim (piv txwv li, tensile, UT) thiab muab daim ntawv pov thawj Hom 3.2.

Q6: Lub sijhawm xa khoom ib txwm rau cov yeeb nkab sib xyaw ua ke no yog dab tsi?
A: Rau thawj zaug xaj ntawm cov qauv sib xyaw ua ke, kev xa khoom feem ntau yog 60-90 hnub (suav nrog kev yuav khoom siv, kev sib xyaw ua ke, kev ua tiav txias thiab kev sim).
