Tib echanjeur chalè ASTM A199
Tib echanjeur chalè ASTM A199 yo itilize prensipalman nan konstriksyon ekipman echanjeur chalè. Sa yo se sitou itilize nan endistri pwosesis tankou raffinerie lwil oliv ak plant pétrochimique. Tib kondansateur SA 199 T11 yo nan gwo demann nan kondansateur gaz akòz pwopriyete fizik ak mekanik yo.
ASTM A199 Chalè Echanjeur Tib Founisè-GNEE
ASTM A199/A199M se yon spesifikasyon pou san pwoblèm frèt trase alyaj asye chalè echanjeur tib ak tib kondansateur. Tib echanjeur chalè alyaj yo te fè nan asye segondè-klas fè ak lòt materyèl alyaj. Tib echanjeur chalè san pwoblèm yo nan gwo demann nan mache a akòz pwopriyete inik yo ki gen ladan: gwo fòs rupture, durability ak rezistans korozyon. Gwoup GNEE founi ASTM A199 T4, ASTM
A199 T5, ASTM A199 T9, ASTM A199 T11 ak ASTM A199 T22.
