ASTM A53 yog ib qho ntawm cov khoom siv dav tshaj plaws rau cov yeeb nkab steel siv hauv cov roj thiab roj thiab lwm cov txheej txheem kev lag luam. ASTM A 53 qib B yog qhov nrov dua li lwm qib. Cov hlab no tuaj yeem liab qab yam tsis muaj txheej txheej, lossis lawv tuaj yeem ua zinc lossis kub dip coated thiab tsim los ntawm vuam lossis cov txheej txheem tsim seamless.
Hauv cov roj thiab roj, cov kav dej A53 qib yog siv rau hauv cov qauv thiab tsis tseem ceeb. Lawv tsis siv hauv cov kev pabcuam hydrocarbon lossis hauv cov kev pabcuam uas cuam tshuam nrog lub siab thiab kub.
Qhov ntau thiab tsawg thiab hom raj xav tau hauv ASTM A53 tus qauv
Cov qauv no suav nrog cov yeeb nkab loj NPS 1/8 "rau NPS 26". Qhov no yog sib npaug rau DN 6 rau DN 650.
Muaj peb hom kav dej uas tau them los ntawm tus qauv no.
Hom F - Rauv taub qab welded raj.
Qib A
F Garde Ib hom yeeb nkab yog tsim los ntawm cov kauj txuas txuas ntxiv, thiab cov kab sib txuas ntev yog welded los ntawm forge welding. Cov txheej txheem no siv cov txheej txheem ntawm cov chais uas tsim cov tshuab ua haujlwm siab rau cov sib koom kub kawg ntawm lub kauj.
Hom E - Hluav taws xob tiv thaiv welded raj.
Qib A
Qib B
Garde A thiab Garde B cov kav dej ntawm hom E yog tsim los ntawm cov kauj txuas txuas ntxiv, thiab cov kab sib txuas ntev yog welded los ntawm cov cua sov uas tsim los ntawm hluav taws xob tsis kam ntawm qhov sib txawv ntawm cov yeeb nkab. Ib txheej ntawm rollers kuj tau siv rau hauv cov txheej txheem no los koom nrog cov cua sov kawg. Weld hlaws ntawm qib B kav dej yog kho cua sov tom qab vuam mus rau qhov tsawg kawg nkaus ntawm 540 degree.
Hom S - Seamless Pipes
Qib A
Qib B
S hom kav yog tsim los ntawm txoj kev extrusion.
Cov hlau nyoos siv los ua cov raj yog tsim los ntawm lub qhov cub qhib, hluav taws xob rauv lossis cov pa oxygen yooj yim.
Tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm ASTM A53 kav
Hlau yog lub ntsiab ntawm A53 kav dej. Lwm cov khoom xws li carbon, manganese, phosphorus, sulfur, tooj liab, npib tsib xee, chromium, molybdenum thiab vanadium kuj muaj nyob rau hauv me me. Saib cov lus sib xyaw tshuaj rau hom E, F thiab S.

ASTM A53 Mechanical Properties
Qhov tsawg kawg nkaus tau txais txiaj ntsig rau lub zog tensile thiab lub zog yield hauv Mpa rau kev ntsuas tshuab ntawm ASTM A53 cov kav dej tau teev tseg hauv qab no.

Tube kuaj thiab kuaj
Thaum lub sij hawm soj ntsuam cov kav dej, cov kev ntsuam xyuas hauv qab no yuav tsum tau ua nyob rau hauv cov kav dej los xyuas qhov zoo ntawm cov khoom kawg.
Tshuaj ntsuam xyuas cov khoom kawg. Tus naj npawb ntawm cov kev xeem - 2 raj rau ib pob ntawm 500 lossis 2 raj rau ib lub xov tooj cua sov. Yog tias ib qho ntawm cov raj tsis ua haujlwm, ob lub raj ntxiv los ntawm tib pawg yuav raug sim.
Tensile test - Qhov kev sim no yog ua los xyuas cov khoom siv ntawm lub raj. Nyob rau hauv cov ntaub ntawv ntawm welded kav, lub zog ntawm weld yuav tsum tsis txhob tsawg tshaj li ntawm cov yeeb nkab lub cev.
Bending Test - Rau cov yeeb nkab loj NPS 2 thiab me me dabtsi yog khoov xeem yog ua los xyuas cov ductility ntawm cov yeeb nkab. Kev ntsuas khoov tuaj yeem yog 90 degrees lossis 180 degrees nyob ntawm qhov xav tau.
Flattening Test - Cov kav dej loj dua NPS 2 raug sim rau ductility siv qhov kev ntsuas flattening. Ib qho piv txwv ntawm cov yeeb nkab yog txiav thiab muab tso rau ntawm ob qhov chaw tiaj tus thiab flattened raws li tau teev tseg hauv ASTM A53.
Kev sim hydraulic - Qhov kev sim no yog ua los ntawm txhua ntu ntawm cov yeeb nkab los xyuas qhov nruj. Lub siab yuav tswj tau li 5 vib nas this lossis ntau dua.
Ultrasonic los yog electromagnetic test ntawm weld hlaws - Qhov kev ntsuam xyuas tsis muaj kev puas tsuaj no yog ua raws tag nrho qhov ntev ntawm qhov vuam los xyuas nws cov khoom khov.
