1. ** Qhov ntsuas kub ntawm Astm A335 P22: **
* ** Kev ua haujlwm cov kev ua haujlwm: ** {-29 degree ({}}}}}} degree (1100 degree f) **.
* ** Cov kev txiav txim siab tseem ceeb: **
* Hauv qab no {-29 degree ({}}}}}}} Kev xeem F): Yuav tsum muaj kev cuam tshuam kom ntseeg tau tias muaj kev lom zem thiab tsis txhob muaj nkig.
* Saum toj 593 degree (1100 degree f): lub zog txo qis dua. Cov kev pabcuam ntev ntev saum toj no ** 565 degree (1050 degree f) ** Axetence degradation (oxidation, nkag) thiab yuav tsum tau ua tib zoo tsim. Qhov kev pab txuas ntxiv mus txuas ntxiv yog feem ntau suav hais tias ** ~ 593 degree (1100 degree f) **.
2. ** Yog P22 Stainless Hlau? **
* ** TSIS MUAJ, P22 tsis yog hlau hlau. ** Nws yog tus hlau qis-alloy (tshwj xeeb ib qho chromium-molybdenum hlau). Thaum nws muaj chromium (~ 2.25%), qib no yog qis dua qhov tsawg kawg nkaus ~ 10.5% CREAATION STORLATION. Nws lub hom phiaj tseem ceeb yog qhov siab-kub lub zog thiab cov quav tsis haum, tsis xeb tawm tsam zoo li cov hlau stainless.
3. ** Qib kawm yog dab tsi A335? **
* ** ASTM A335 ** yog cov qauv tshwj xeeb: "
* "** QIB ** yog hais txog qhov tshwj xeeb alloy * hauv * A335 specification. P22 yog ib qib twg. Lwm cov qib kawm suav nrog P5, P9, P11, P91, P91, P92, thiab lwm yam.
* ** Yog li: ** A335 txhais tau qhov * Hom * ntawm cov yeeb nkab (cov hlau uas siv tau (piv txwv li, p22) txhais cov khoom siv tshwj xeeb thiab cov khoom siv.
4. ** Dab tsi yog ATM sib npaug ntawm A335? **
* Lo lus nug no yog me ntsis misphrased. ** ASTM A335 * yog * astm specification. ** Tsis muaj tus lej ASTM sib txawv uas yog "sib npaug" rau A335 nws tus kheej.
* ** Koj yuav txhais tau (sib npaug thoob ntiaj teb): ** Yog tias koj txhais tau hais meej cov lus qhia los ntawm * Lwm cov koom haum * Cov Koom Haum Qauv:
* ** RAU \/ ISO: ** TO 10216-2 (Seamless Cov Menyuam Yaus - Cov Khoom Siv Hluav Taws Xob - Qhov Tsis Muaj-Alloy thiab Alloy Steel Leeg nrog cov khoom ntsuas kub thiab ntsuas). Qhov ze tshaj plaws rau P22 yog feem ntau txiav txim siab ** 13Crmo {}} (1.7335) ** lossis ** rau cov ntawv thov sib txig zoo sib xws yuav tsum muaj cov ncauj lus kom ntxaws.
* ** JIS (Nyiv): ** JIS G 3458 (Alloy Steel Kave rau kev pab kub ntawm kub). Qhov kawg yog ** STPA24 ** **.
* ** CEEB TOOM: ** "Sib npaug" yog feem ntau * zoo sib xws *, tsis yog * tib yam *. Daim ntawv thov tseem ceeb yuav tsum muaj cov ncauj lus piav qhia ntxaws ntxaws ntawm cov tshuaj, kho tshuab, thiab kev soj ntsuam.
5. ** Qhov sib txawv ntawm ASTM thiab ASME YEES: **
* ** ASTM (American Society rau kev sim thiab cov khoom siv) cov khoom siv neeg siv tshuaj ntsuab (og)
* ** ASME (Asmeskas haiv neeg ntawm cov neeg kho tshuab engineers): ** Kev tsim kho * Tsim thiab tsim qauv *, feem ntau yog BPVC (boiler thiab siab vessel code) **. ASME Adopts Astm Khoom Cov Khoom Siv (piv txwv li, ** {{0} -335} **, thiab feem ntau ntxiv cov kev xav tau ntxiv.
* ** Hloov qhov sib txawv: **
* ** Tsom: ** ASTM txhais * Cov khoom siv yog *. ASME TXHAIS * Yuav siv cov khoom muaj kev nyab xeeb * hauv cov khoom siab (tsim qauv, kuaj, kuaj xyuas).
* ** SAU: ** ASTM npog cov ntaub ntawv raw (daim hlau, kav dej, fittings, bolts, thiab lwm yam). ASME BPVC npog cov qauv tsim, thiab tshuaj xyuas ntawm boilers, cov raj kav dej siab, thiab cov khoom siv hluav taws xob zoo li cov astm).
* ** Daim ntawv pov thawj & cim: ** Cov kav dej tsim los ua cov astm specs kom tau raws li cov khoom yuav tsum tau ua. Cov kav dej tsim mus rau tus coj Asme Spec (SA-XXX) Raws li cov khoom yuav tsum tau ua * thiab * yuav muaj kev tsim kho ntxiv kom ua tau rau ASME Code Siv. Lawv tau txais cov ** Asme code cim cim npe ** (piv txwv li, "S" rau lub zog boilers).
* ** AUTE: ** ASTM SPECTS yog cov qauv dawb. ASME BPV Txoj Cai Code feem ntau yog raws li kev cai lij choj rau cov cuab yeej siv siab.
* ** Kev sib raug zoo: ** ASME Nquag koom ua ke TTM cov khoom siv tau los ntawm kev siv, ua ntej _ -335). ASME yuav ntxiv ntxiv yuav tsum tau ua ntxiv (piv txwv li, kev sim ntxiv, kub dua kev siv zog) rau kev siv code.
