ASTM A618 STEEL HOLLOW seem yog dab tsi?

ASTM A618 steel yeeb nkab yog ib qho welded thiab seamless yeeb nkab uas tsim los ntawm lub zog siab qis alloy (HSLA) hlau. Nws muab cov khoom kho kom zoo dua qub dua carbon steel rau kev xav tau kev pabcuam.

Kev tsim khoom

Seamless A618 yeeb nkab yog kub extruded thaum welded yeeb nkab pob qij txha yog fusion welded siv high kub input txheej txheem. Cov txheej txheem vuam kom raug thiab tsis yog- kev kuaj kev puas tsuaj ua kom cov vuam zoo ua tau raws li ASTM cov qauv.

Daim ntawv thov

A618 yeeb nkab pom cov ntawv thov hauv refineries, tshuaj nroj tsuag thiab lub zog tsim kev lag luam rau kev thauj mus los ntawm kev kub siab chav, dej kub / txias thiab slurries vim nws cov khoom muaj zog, tensile zog thiab corrosion kuj.

Teem caij thiab qhov ntau thiab tsawg

Nws muaj nyob rau hauv ntau yam yeeb nkab teem caij raws li ASTM A106 nrog tus qauv qhov ntev xws li 1/2 "mus rau 60". Phab ntsa thickness sib txawv raws li qhov sib txawv siab ntsuas.Saib cov lus qhia tshwj xeeb

Cov txiaj ntsig zoo tshaj Carbon Steel

Lub zog siab dua tso cai rau cov phab ntsa nyias, txo qhov hnyav. Zoo heev toughness kom muaj kev ruaj ntseg tiv thaiv brittle failures. Kev tiv thaiv kev tawg thiab corrosion kuj ua rau nws tsim nyog rau kev xav tau kev pabcuam.

Kev xeem thiab ntawv pov thawj

Ua tau raws li txhua qhov kev ntsuam xyuas hydrostatic thiab flattening raws li ASTM A106. Cov ntaub ntawv kuaj xyuas zeb suav nrog kev tshuaj xyuas tshuaj thiab kev ntsuas siab ua kom pom tseeb cov yeeb nkab zoo.
