Tag nrho peb cov khoom thiab cov kev daws teeb meem ua tau raws li cov qauv zoo thoob ntiaj teb thiab tau txais txiaj ntsig zoo hauv ntau lub khw thoob ntiaj teb. Yog tias koj txaus siab rau ib qho ntawm peb cov khoom lossis xav tham txog kev txiav txim siab, nco ntsoov tiv tauj peb. Peb tau tos ntsoov rau kev tsim kev lag luam kev sib raug zoo nrog cov neeg siv khoom tshiab nyob rau yav tom ntej.
ASTM A53 qhia txog qhov yuav tsum tau ua rau seamless / welded dub thiab kub-dip galvanized steel kav rau kev siv dav. Cov hlau uas teev nyob rau hauv tus qauv yuav tsum tau ua tiav nyob rau hauv ib qho qhib cua rauv, alkaline oxygen los yog hluav taws xob rauv, thiab yuav tsum muaj cov tshuaj raws li nram no: carbon, manganese, phosphorus, sulfur, tooj liab, npib tsib xee, chromium, molybdenum thiab vanadium. Lub raj xa dej yuav tsum yog seamless lossis welded. Tensile, dabtsi yog khoov thiab flattening xeem yuav tsum tau ua los xyuas kom meej tias nws yuav tsum tau raws li tus txheej txheem mechanical zog. Kev ntsuas hydrostatic siab yuav tsum tau ua, thiab tsis muaj qhov xau los ntawm lub vuam lossis cov yeeb nkab lub cev. Kev ntsuas hluav taws xob tsis muaj kev puas tsuaj yuav tsum tau ua kom ntseeg tau tias tag nrho cov ntim ntawm cov kav dej yuav tsum ua tau raws li tus qauv. Yog tias pom tau tias tsim nyog los xyuas kom meej tias lub raj xa dej ua tau raws li qhov yuav tsum tau ua, tus neeg yuav khoom muaj cai ua txhua yam kev tshuaj xyuas thiab kev ntsuam xyuas tau teev tseg hauv cov lus qhia no.
ASTM A 53 yog tsim rau cov kav dej siab, cov kav dej rau cov kav dej thiab cov kav dej dav dav ntawm qhov kub ntawm 350 degrees. Ntawm lawv, Gr.B steel qib yog feem ntau siv, nrog nws lub zog tensile ≥ 415 (MPa) thiab yield zog ≥ 240 (MPa).
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
