ASTM A53 Scope
Seamless thiab welded steel kav los ntawm DN 6 mus rau 650 mm nrog phab ntsa thicknesses raws li ASTM A53 Tables X2.2 thiab X2.3, raws li zoo raws li galvanized steel kav.
ASTM A53 Hom thiab Qib
Hom yeeb nkab
Hom F:
Furnace Butt-Welded Pipe - Nruam welded yeeb nkab.Ua ntau qhov ntev ntawm cov yeeb nkab, uas tom qab ntawd txiav mus rau hauv ib tus neeg ntev thiab welded los ntawm cov neeg kho tshuab siab tsim los ntawm cov yob kub.
Lus Cim: Hom F tsis muaj nrog flanges
Hom E:
kuj-welded yeeb nkab.Lub taub qab ntev sib koom ua ke nyob rau hauv ib qho ntev, los yog nyob rau hauv ntau qhov ntev ntawm qhov ntev ntawm lub crimped casing, ces txiav mus rau hauv ib tug ntev ntev, muaj ib tug longitudinal pob tw, nyob rau hauv lub merger yog tsim los ntawm tshav kub tau txais los ntawm cov tsis kam ntawm tam sim no nyob rau hauv lub Circuit Court nyob rau hauv ib tug longitudinal pob tw. uas cov yeeb nkab yog nyob, thiab los ntawm kev siv lub siab.
Lus Cim: Hom E yog rooj tog tsis tau nthuav dav lossis txias nthuav dav ntawm qhov kev xaiv ntawm cov chaw tsim khoom.
Hom S:
Seamless Piping - Weldless Pipe Joints Nws yog tsim los ntawm cov hlau ua haujlwm kub, yog tias tsim nyog, los ntawm kev ua haujlwm txias tom qab ntawm cov khoom kub ua haujlwm tubular los tsim cov khoom xav tau, qhov loj me, thiab cov khoom.
Qib Group
Qib A:
Qhov no yog qib hauv paus thiab tsim nyog rau kev hloov pauv cov kua dej uas tsis tshua muaj siab thiab qee qhov kev siv cov qauv.

ASTM A53 Lwm yam kev sim
Khoov Test
DN 50 (NPS 2) lossis me dua: qhov ntev txaus ntawm cov yeeb nkab yuav tsum muaj peev xwm khoov txias los ntawm 90 ° ncig lub cylindrical mandrel, txoj kab uas hla yog kaum ob npaug ntawm cov kab sab nraud ntawm cov yeeb nkab, yam tsis muaj qhov tawg ntawm ib feem thiab tsis qhib. lub vuam.
Kaw coiling: cov yeeb nkab yuav tsum sawv ntsug kom txias txog 180°nyob ib ncig ntawm lub cylindrical mandrel, txoj kab uas hla ntawm uas yog yim npaug ntawm qhov teev sab nraud ntawm cov yeeb nkab, tsis muaj kev ua haujlwm.
Ob chav-ntxiv-muaj zog yeeb nkab tshaj DN 32 (NPS 11/4):tsis tas yuav raug kuaj khoov.
Flattening Test
Welded yeeb nkab tshaj DN 50 hli hauv qhov hnyav ntxiv lossis sib dua: yuav tsum tau ua kom flattening.
Seamless Yeeb Nkab: Tsis muaj kev sim.
Hydrostatic Test
Plain-End Pipe: Siv tau raws li Table X2.2.
Threaded thiab Coupled Yeeb Nkab: Siv tau raws li Table X2.3.
Nondestructive Electric Test
Yog tias qhov ntsuas hluav taws xob tsis muaj kev puas tsuaj tau ua tiav, qhov ntev yuav tsum tau sau nrog cov ntawv "NDE".
Galvanized
ASTM A53 Galvanized yeeb nkab yuav tsum tau galvanized sab hauv thiab sab nraud los ntawm cov txheej txheem kub dip.
Cov zinc siv rau txheej yuav tsum yog qib zinc ua raws li Specification B6.Cov yeeb nkab galvanized yuav tsum tsis pub dawb los ntawm qhov chaw tsis muaj coated, hlwv pob, flux deposits, thiab gross dross inclusions.Lumps, projections, globules, los yog hnyav deposits ntawm zinc uas yuav cuam tshuam nrog kev npaj siv cov khoom yuav tsis raug tso cai.
Qhov saum npoo ntawm cov yeeb nkab steel yuav tsum muaj zinc txheej tsis pub tsawg dua 0.40 kg / m² los ntawm kev suav ntawm qhov hnyav thiab thaj tsam ntawm cov txheej galvanized.
