1. ** Dab tsi yog lub hardness ntawm Astm A333? **
ASTM A333 qhia meej txog cov yeeb nkab qis thiab welded steel yeeb nkab rau cov ntawv thov siab. Nws tsis ncaj qha rau cov kev xav tau yooj yim tab sis tsom rau tensile lub zog, muab lub zog nruj (piv txwv li cov kev sim siab v-tsis yog qhov ua tau zoo hauv qhov chaw qis. Kev tawv tawv muaj nuj nqis, yog tias yuav tsum tau, yuav tsum muaj nyob ntawm qib (piv txwv li qib 1 mus rau qib 11) thiab feem ntau yog muab los ntawm cov khoom siv cov khoom siv neeg kho mob.
2. ** Yuav ua li cas Astm A53 sawv rau? **
ASTM A53 yog tus qauv kev qhia tshwj xeeb rau ** Carbon Steel yeeb nkab **, suav nrog kev ua tsis taus thiab welded hom. Nws npog cov kav dej siv rau cov kav hlau thiab kev siv siab (piv txwv li, dej, dej, lossis siv cov kev pabcuam kub tsawg.
3. ** Yog ASTM A53 hom E lossis S? **
ASTM A53 suav nrog peb hom:
- ** HOM E ** (hluav taws xob tiv thaiv welded),
- ** Hom S ** (Seamless),
- ** HOM F ** (rauv thaiv welded).
Ob hom e thiab hom s muaj nyob; Lawv xa mus rau txoj kev tsim khoom, tsis yog ob txoj kev sib txuas tau tshwj xeeb.
4. ** Dab tsi yog astm A106 A53 cov lus qhia tshwj xeeb? **
ASTM A106 thiab ASTM A53 yog cais cov qauv:
- ** ASTM A106 ** XEEM Seamless Cov Hlau Yeeb Nkab Rau Cov Kev Pab Kub Kub (piv txwv, Chav, Roj Chaw Ua Si).
- ** ASTM A53 ** COV TSWV YIM OB WELDED THIAB Seamless Cov Yeeb Nkab Rau Cov Hlau Hlau rau General-Lub Hom Phiaj Siv (qis dua kub \/ nias).
Lawv tsis ua ke; Cov lus nug yuav sib xyaw ob qho tshwj xeeb cov lus qhia tshwj xeeb.
5. ** Dab tsi ASTM txhais tau? **
** ASTM ** sawv rau ** Hmoob Meskas rau kev kuaj thiab cov ntaub ntawv ** (tam sim no ** ttm thoob ntiaj teb **). Nws yog ib lub koom haum uas nthuav tawm thiab tshaj tawm cov qauv kev ua haujlwm, cov khoom lag luam, cov tshuab, thiab cov kev pabcuam thoob plaws kev lag luam kom paub meej tias qhov zoo thiab kev nyab xeeb.
