ASTM A815 UNS S32760 yog ib qho kev qhia tshwj xeeb uas tsim los ntawm American Society for Testing and Materials (ASTM) uas npog cov qauv kev cai rau wrought ferritic, austenitic, thiabduplex steel taub qab-welding fittings. Cov fittings no yog npaj rau siv nyob rau hauv ntau yam high-corrosion thiab high-zog ib puag ncig, ua rau lawv haum rau kev siv nyob rau hauv kev lag luam xws li roj thiab roj, petrochemical, tshuaj ua, thiab lwm yam.
Butt-weld haum yog cov khoom siv los txuas cov kav dej thiab cov kav dej, tso cai rau kev sib txuas tsis sib haum thiab tsis muaj pov thawj. Lawv tau siv dav hauv cov kav dej uas muaj cov kua dej ntws thiab cov khoom ntim tseem ceeb. ASTM A815 UNS S32760 buttweld haum yog tsim los ntawm cov txheej txheem vuam uas koom nrog ob daim yeeb nkab lossis tubing los ntawm cua sov rau lawv thiab tom qab ntawd sib txuas ua ke.
