ASTM A312 TP304, ASTM A312 Tube
Studded yeeb nkab yog ib hom yeeb nkab siv hauv kev lag luam roj thiab roj. Nws yog lub raj xa dej nrog studs lossis bolts welded rau nws qhov chaw. Cov studs no ua haujlwm rau qhov chaw nres tsheb rau cov khoom siv txuas ntxiv lossis cov khoom siv xws li li qub, flanges, thiab fittings. Cov studs feem ntau yog tsim los ntawm cov hlau thiab yog welded rau ntawm cov yeeb nkab nto ntawm qee lub sijhawm thiab qhov chaw txiav txim los ntawm qhov project specifications. Qhov loj thiab tus naj npawb ntawm cov studs siv nyob rau hauv ib tug studded yeeb nkab yog txiav txim los ntawm txoj kab uas hla ntawm cov yeeb nkab, lub siab ntsuas, thiab qhov hnyav ntawm cov khoom yuav tsum tau txuas.
Studded yeeb nkab yog dav siv nyob rau hauv high-pressure thiab high-temperature cov xwm txheej uas qhov hnyav ntawm cov khoom sib txuas tuaj yeem ua rau muaj kev cuam tshuam loj rau hauv cov kav dej. Cov studs ua hauj lwm raws li qhov chaw ruaj khov, faib qhov hnyav sib npaug thoob plaws lub raj xa dej thiab txo qhov txaus ntshai ntawm kev ntxhov siab cuam tshuam los yog ua tsis tiav.

Carbon steel, stainless hlau, thiab alloys xws li Inconel thiab Monel yog cov ntaub ntawv siv los ua cov kav dej studded. Cov khoom siv yog txiav txim siab los ntawm kev siv tshwj xeeb nrog rau kev txiav txim siab xws li kub, siab, thiab corrosive zoo ntawm cov kua uas raug thauj.

Qhov sib nrug thiab kev teeb tsa ntawm cov studs yog qhov tseem ceeb heev thaum siv cov kav dej studded. Qhov sib nrug txaus ua kom ntseeg tau tias cov khoom siv txuas nrog qhov hnyav tau muab faib ua tib yam, txo qhov kev pheej hmoo ntawm kev ntxhov siab cuam tshuam lossis tsis ua haujlwm. Kev npaj ntawm cov studs kuj tuaj yeem cuam tshuam rau cov yeeb nkab kev ua tau zoo ntawm cov kua dej ntws thiab siab poob. Yog li ntawd, cov kav dej studded tau nquag tsim thiab tsim ua raws li kev lag luam cov qauv thiab cov cai.
