Enfòmasyon konplè sou ASTM A312 tiyo asye
ASTM A312 se yon estanda kle pou tib asye pur austenitic (san soude, soude, frèt -travay) yo itilize nan gwo -tanperati / anviwònman korozivite. Li kouvri klas materyèl tankou TP304/L ak TP316/L, epi li apwopriye pou endistri tankou pétrochimique, manje, ak pharmaceutique. Estanda sa a presize pwosesis fabrikasyon, metòd tès (tansyon, plati), dimansyon (NPS 1/8 "a 30" +), epi li mande pou materyèl yo dwe pwòp epi gratis nan echèl oksid pou asire fyab. Li garanti fòs, duktilite, ak rezistans korozyon, kidonk bay pèfòmans serye menm nan kondisyon difisil.
Ki sa ki tiyo ASTM A312?
Tiyo ASTM A312 se yon tiyo jeneral -bi asye pur lajman ki itilize nan divès endistri yo. Dyamèt li yo varye ant 1/8 pous ak 30 pous, ak epesè miray li yo varye ant SCH 10S ak SCH 80S. Klas materyèl yo souvan itilize yo se TP304/304L ak TP316/316L.
Eksteryè Dyamèt: 10.3mm-609.6mm
Epesè miray: 0.2mm-60mm
Longè: 5-12m oswa Customized sou demann
Aplikasyon: Ba-likid presyon, dlo, gaz, tiyo lwil oliv, tiyo jeni chodyè, elatriye.
Pwosesis adisyonèl: koneksyon ki senp oswa file (avèk priz oswa bizote, ak bouchon plastik), tès idrostatik, tès kouran eddy, analiz tèmik enfrawouj
Tretman Sifas: Rekwir klere, marinated, sablaj oswa pasivasyon
Kondisyon livrezon: cho woule, frèt trase
Klas asye: TP304, TP304L, TP316, TP316L, TP321, TP347
