### 1. Dab tsi yog qhov sib txawv ntawm ASTM thiab ASME YEES?
Cov ntsiab lus tseem ceeb ntawm cov lus dag nyob hauv qhov tau txais thiab lub hom phiaj ntawm cov qauv teem los ntawm ob lub koom haum no.
* ** ASTM (American Society rau kev sim thiab cov ntaub ntawv) ** ** yog cov ntaub ntawv cov ntaub ntawv tshwj xeeb. Ib ** ASTM ** tus qauv (piv txwv li, A106, A53) txhais cov khoom siv * (* Cov txheej txheem kev tsim khoom * (* Cov qauv siv tshuab), thiab * kev sim tshuaj * rau cov khoom siv nyoos rau nws tus kheej. Nws qhia txog dab tsi cov yeeb nkab tau ua los ntawm thiab nws cov khoom tseem ceeb.
* ** ASME (Asmeskas haiv neeg ntawm cov kws kho tshuab engineers) ** yog tus qauv tsim thiab kev tsim kho lub zej zog. Ib ** ASME ** tus qauv (uas feem ntau adopts cov khoom siv astm) txhais cov yeeb nkab *, * kev soj ntsuam cov tshuaj lom zem * Nws qhia txog li cas cov yeeb nkab yuav tsum tau siv nyob rau hauv lub system.
Hauv ntej: ** ASTM qhia meej cov khoom siv thiab kev tsim cov yeeb nkab. ASME qhia txog kev siv cov yeeb nkab ntawd hauv cov ntawv sau tshwj xeeb tab sis tsis tuaj yeem ua tau rau ib qho kev thov ua Asme

### 2. Dab tsi yog ATTM A106 thiab ASME SA106?
Qhov no yog ib qho piv txwv zoo meej ntawm kev sib raug zoo ntawm Astm thiab ASME.
* ** ASTM A106 ** yog tus qauv tshwj xeeb rau cov khaub ncaws seamless steel tsis zoo tsim rau high- kub kev pab. Nws npog cov tshuaj, tshuab, thiab qhov chaw nyob sab nraud rau cov yeeb nkab.
* ** ASME SA36 ** yog ASME BOILER thiab siab lub siab boiler code (BPCC) kev tsim qauv uas * ANTM A106 cov lus qhia tshwj xeeb. Thaum cov yeeb nkab cov chaw tsim yeeb ua yeeb nkab tsim cov yeeb nkab rau A106 tus qauv thiab cov txheej txheem pov thawj zoo ntxiv los ntawm kev cai lij choj, lawv tuaj yeem siv tau nws li ** sa106 **.
Qhov tseem ceeb, cov khoom siv yog tib yam. Tus "S" hauv Sa106 tau qhia tias nws yog ib qho khoom siv ASME code haum rau siv rau hauv boilers, siab- kev cai siab}}} kev cai siab.

### 3. Dab tsi yog Astm qauv rau hlau?
ASTM tsis muaj ib tus qauv rau cov hlau. Hloov chaw, nws muaj ntau pua tus qauv sib txawv uas npog ntau yam ntawm cov hlau hom steel, qib, thiab npaj siv. Cov qauv no tau teeb tsa los ntawm hom hlau:
* ** CARBON STEEN: ** Cov qauv xws li A53 (AVENT siv), A106 (siab} kev pabcuam kub), A500 (tub sab teeb).
* ** ALLOY STEEL: ** Cov qauv zoo li A335 (seamless ferritic alloy {}} steel yeeb nkab rau siab kub).
* ** Stainless hlau: ** Cov qauv zoo li A312 (seamless thiab welded stainless hlau yeeb nkab).
* ** Cov qauv hlau qauv: ** Cov qauv zoo li A36 (carbon qauv hlau) thiab A500 (tub kev tub sab).
Txhua tus qauv txhais tau qhov tshwj xeeb rau cov hlau nws npog.

### 4. Dab tsi yog astm txheem rau teem sijhawm 40 steel yeeb nkab?
"Teem sijhawm 40" tsis yog Astm qauv nws tus kheej; Nws yog ** phab ntsa thickness tsim ** Sau los ntawm ASME B36.10M (rau cov roj carbon thiab alloy b36.19m (rau cov hlau stainless). Nws qhia tau ib qho tuab tuab rau ib qho yeeb nkab taub.
Ntau cov qauv yeeb nkab astm suav nrog cov kav dej uas tau ua nyob rau hauv sijhawm 40 tuab. Cov feem ntau muaj yog:
* ** ASTM A53: ** Qib b (seamless lossis welded) {{1} {- siab thauj.
* ** ASTM A106: ** THEM B -} rau high- kub kev pab.
* ** ASTM A500: ** Qib B lossis C -}} rau cov ntawv thov kev tsim qauv.
* ** AVTM A312: ** Hom 304 / 304L - rau cov ntawv thov stainless {}}}} tiv taus cov ntawv thov.
Yog li, koj yuav qhia cov yeeb nkab raws li ** "ANTM A53 qib B, teem sijhawm 40" ** ** lossis ** ASTM A106 qib B, teem sijhawm 40. "** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** **

### 5. Puas yog ASTM A53 Teem Sij Hawm 40?
** AVEM A53 tsis yog nws tus kheej teem sijhawm 40. **
Txawm li cas los xij, cov yeeb nkab uas conforms rau tus ** AFTM A53 tus qauv yog feem ntau tsim thiab muaj nyob rau hauv sijhawm 40 phab ntsa tuab **, xws li cov sijhawm 80, 160, STD, Xs). Yog li, nws yog qhov tseeb rau kev txiav txim lossis xa mus rau cov yeeb nkab raws li ** "ANTM A53 Teem caij 40." **
