ASTM A335 / ASME SA335 yog ib qho kev qhia tshwj xeeb rau seamless ferritic alloy steel raj siv hauv kev pabcuam kub (540 - 750 ° C) thiab hauv kev lag luam boiler. Cov kev qhia tshwj xeeb npog cov kav dej ntawm cov phab ntsa nominal thiab cov phab ntsa tsawg kawg nkaus uas muaj cov khoom siv alloy thiab tsim hauv hom seamless.
ASTM A335 P1 seamless steel yeeb nkab yog cov khoom siv yeeb nkab tseem ceeb hauv kev tsim kho thiab kev siv siab. Nws yuav raug tsim los ntawm kub dov thiab kos duab txias. Cov khoom siv raug siv hauv kev hloov cov roj thiab roj, cov dej kub siab, cov qauv tshwj xeeb, kev thauj mus los ntawm cov tshuaj tshwj xeeb, thiab lwm yam. Sab nrauv tuaj yeem kho los ntawm galvanizing, pleev xim, PE txheej, PP txheej, HDPE txheej, thiab lwm yam.
Cov ASTM A335 P1 seamless steel kav no muaj nyob rau hauv sib txawv ntev thiab diameters rau ntau yam kev siv thiab yog ua los ntawm superior zoo. Cov ASTM A335 P1 seamless steel kav no muaj zog heev thiab muaj lub neej ua haujlwm ntev. Lub ntsiab kom zoo dua yog hais tias lub thickness yuav loj, ces siab siab yuav loaded rau hauv uas tsis muaj steel hlau. Lub sij hawm siv tau zoo yuav nyob ib puag ncig 50-70 xyoo. Tus qauv tuaj yeem yog API, ASTM, JIS, thiab lwm yam.
