Dimensions Thiab Specifications ntawm Pressure Vessel Phaj

Lub thickness ntawm cov phaj siab feem ntau yog li ntawm 5 mus rau 200mm, uas tau muab faib ua ob peb thickness specifications. Lub teb chaws cov qauv teev cov phaj qhov ntau thiab tsawg thiab tso cai sib txawv. Cov tsos mob zoo (1) Cov duab ntawm cov hlau phaj: xws li mob nkhaus, flatness, lub kaum sab xis, thiab lwm yam. (2) Deg defects: deg tsis xws luag ntawm cov hlau phaj feem ntau muaj xws li tawg, nti, flattened npuas, impurities, bulges, pores, nias hlau oxide nplai, thiab lwm yam. Vim muaj kev ruaj ntseg, lub siab lub nkoj steel daim hlau muaj qhov yuav tsum tau nruj me ntsis ntawm qhov chaw thiab sab hauv tsis xws luag. Cov teeb meem saum toj no feem ntau tsis pub muaj nyob. Txawm li cas los xij, nws raug tso cai kom raug tshem tawm nrog txoj kev tsim nyog, thiab qhov chaw tshem tawm yuav tsum tiaj tus. Nws thickness yuav tsum tsis pub tshaj qhov sib txawv ntawm steel phaj thickness. Feem ntau, mezzanines tsis raug tso cai. Chemical composition index:
① Carbon steel phaj: feem ntau kuaj pom carbon, silicon, manganese, phosphorus thiab sulfur cov ntsiab lus. Qee cov pa roj carbon steel kuj muaj qee qhov tooj liab, chromium, nickel, molybdenum, vanadium thiab lwm yam khoom. Ntawm lawv, cov pa roj carbon monoxide yog qhov tseem ceeb uas txiav txim siab lub zog ntawm cov hlau phaj, uas yog, lub zog ntawm cov hlau phaj nce ntxiv thaum cov ntsiab lus carbon nce. Cov ntsiab lus ntawm cov pa roj carbon steel yog nruab nrab ntawm {{0}}.16 thiab 0.33%. Manganese thiab silicon kuj muaj txiaj ntsig ntawm kev txhim kho cov ntaub ntawv thiab ua kom muaj zog. Silicon: 0 10-0.55%, manganese: {{10}} 4-1.6%. Qee cov qauv tsis muaj qhov yuav tsum tau muaj silicon thiab manganese rau cov phaj boiler zoo tib yam, thiab tooj liab yog qis dua 0.30%. Lwm cov qauv xws li Nyiv thiab Russia tsis muaj cov ntsiab lus tooj liab. Qee cov hlau zoo muaj chromium (tsawg dua 0.25%), nickel (tsawg dua 0.30%), molybdenum (tsawg dua 0.10%), thiab vanadium (tsawg dua 0.03%).
② Tsawg alloy steel phaj: Ntxiv nrog rau cov ntsiab lus muaj nyob hauv cov hlau, kuj tseem muaj qee yam ntawm molybdenum, chromium, npib tsib xee, vanadium, thiab lwm yam. Muaj ntau qib ntawm cov hlau tsis tshua muaj hlau, cov qauv siv ntau dua. Raws li hauv qab no: 1/2 molybdenum, 1/2Mo-B steel: ASTM A204, JIS G3107; Mn-1/2Mo1/2Mo, Mn-1/2Mo-V, Mn -1/2Mo{16}}/4Ni, Mn1/2Mo-1/2N i steel ASTM A302, A533, JIS G3119, G3120; 1Cr-1/2Mo, 11/4Cr-1/2Mo, 21/2Cr-1Mo, 3C r-1Mo, 5Cr-1/2Mo, 7Cr{ {42}}/2Mo, 9Cr{45}}Mo: JISG4109, ASTM A387, A533, DIN17155.
③ Quenched thiab tempered high-strength steel daim hlau: ASTM A517, A537, A724, A734, JISG3115.
④ Tsawg-kub steel: suav nrog carbon steel thiab hlau alloy. ASTMA612, A662, A735, A736, A738, A203, A645, JIS G3126.
⑤ Stainless hlau: JIS G4304, ASTM A240, AISI13, ΓOCT5632.
