Nchịkọta nke efere nickel Cryogenic
Efere nickel cryogenic dabara nke ọma na ngwa ekpughere na oke okpomọkụ dị oke ala. A na-eji ha eme njem nke gas na-egbu egbu (LNG) na mmanụ mmanụ (LPG).
A 645 Gr A / A 645 Gr B, mbelata ọnụ ahịa yana nchekwa na-abawanye na ethylene na owuwu tank LNG.
Ụlọ ọrụ mmepụta ihe ọgbara ọhụrụ na-eme ka anyị nwee ike ịmepụta ma ọkwa ígwè A 645 Gr A na Gr B yana 5% na 9% nickel steels.
● LNG
A na-agbanye mmanụ gas na oke okpomọkụ nke -164 Celsius C, na-ebelata ụda ya site na ihe dị ka 600. Nke a na-eme ka nchekwa na ibufe ya kwe omume na nke ọma n'ụzọ akụ na ụba. N'oge okpomọkụ ndị a dị oke ala, iji ígwè nickel 9% pụrụ iche dị mkpa iji na-ekwe nkwa ductility zuru oke na iguzogide mgbawa. Anyị na-ebunye efere ndị sara mbara na mpaghara ahịa a, ọbụlagodi na ọkpụrụkpụ ruru 5 mm.
● LPG
A na-eji usoro LPG emepụta propane na nhazi gas sitere na gas. A na-agbanye gas ndị a n'ime ụlọ okpomọkụ na obere nrụgide ma na-echekwa ya na tankị pụrụ iche nke 5% nickel steels. Anyị na-ebunye efere shei, isi na cones site n'otu ebe.
Were ASTM A 645 Gr B Plate Dịka ọmụmaatụ
● Iji A 645 Gr A maka mmepụta nke tankị ethylene na-enye ihe dị ka 15% ike dị elu, nchekwa na-abawanye na ohere nke ibelata mgbidi mgbidi maka nnukwu ego na-akwụ ụgwọ na-ewu tank.
● ASTM A 645 Gr B na-enweta ihe onwunwe dị ka nke omenala 9% nickel steels na nchekwa LNG mana ọ na-emezu ihe ndị a chọrọ na ihe dị ka 30% obere nickel ọdịnaya. Nsonaazụ ọzọ na-ebelata nke ukwuu n'ịrụpụta tankị LNG nke dị n'ikpere mmiri na nke dị n'ikpere mmiri yana n'iwu tankị mmanụ ọkụ LNG.
Ogo kachasị elu maka ogo nchekwa kachasị elu
Ndabere nke efere nickel anyị dị elu bụ slabs na-adị ọcha nke sitere na ụlọ ọrụ na-emepụta ígwè nke anyị. Ọdịnaya carbon dị ala na-ekwe nkwa weldability zuru oke. A na-ahụ uru ndị ọzọ na ike mmetụta dị mma nke ngwaahịa na ihe ndị na-agbaji (CTOD). Elu efere niile na-enweta ule ultrasonic. Ihe ndọta fọdụrụnụ dị n'okpuru 50 Gauss.
