SA387 GR.12 CL1 Alloy Pressure Vessel saxan bir ah

A387Gr12CL1 weelka cadaadiska saxanka birta ayaa leh awoodda ugu yar ee soosaarka 275 Mpa, iyo xoogga xajinta gudaha 450-585 Mpa. Weelka cadaadiska ee saxanka birta ah SA387 Fasalka 12 CL 1 waa heerka American ASME SA 387/SA 387M.Boiler steel plate A387 Fasalka 12 Cl 1 waa sida waafaqsan ASTM A387/A387M. Qalabkan birta ah sidoo kale waa inay waafaqaan tafatirka birta A 20/A 20M. Shuruudahani waxay qeexayaan hababka iyo hababka tijaabinta iyo tijaabinta, kala duwanaanshaha la ogol yahay ee cabbirka iyo miisaanka, tayada iyo hagaajinta cilladaha, calaamadaynta, rarista, iwm.

Daawaynta kulaylka ee SA387 Chrom Moly Alloy Steel Plate

Saxanka birta birta ah ee moly alloy ee hoos yimaada ASME SA387 waa in la dilo birta, iyada oo kulayl ahaan lagu daaweeyaa iyada oo la tirtirayo, caadiyeynayo iyo dabci. Ama haddii uu ku heshiiyo iibsadaha, qaboojinta degdega ah ee heerkulka hagaajinta hawada hawada ama dareere deminta, oo ay ku xigto heerkulka, heerkulka heerkulka ugu yar waa inuu ahaadaa sida shaxda hoose:

Darajo	Heerkulka, °F [°C]
2, 12 iyo 11	1150 [620]
22, 22L, 21, 21L iyo 9	1250 [675]
