Karakteristik pwodwi yo
1. Segondè fòs: apwopriye pou gwo presyon ak anviwònman tanperati .
2. Kowozyon rezistans: Disponib ak cho-plonje galvanize tretman sifas .
3. lajè aplikabilite: apwopriye pou petrochemicals, veso presyon, koneksyon bride tiyo, elatriye .
Enstalasyon ak sekirite
1. Torque Espesifikasyon:
Lè w ap enstale ASTM A193 Klas B7 boulon, li enpòtan yo swiv espesifikasyon yo koupl kòrèk asire apwopriye pi sere . kòrèk koupl ka rezilta nan anba-pi sere (sa ki lakòz yon koneksyon ki lach) oswa sou-pi sere (domaje boulon an oswa materyèl la ke yo te tache) .}
2. Thread wilaj:
Pou gwo tanperati oswa aplikasyon pou presyon, fil boulon ka mande pou wilaj pou redwi friksyon epi pou anpeche galon fil (rete soude), ki ka lakòz difikilte pandan enstalasyon oswa retire .
3. enspeksyon:
Se enspeksyon regilye rekòmande, espesyalman pou boulon yo itilize nan kritik, aplikasyon pou wo-estrès . enspekte fil yo boulon ak tèt pou siy nan mete, deformation, oswa domaj .
