Carbon steel flanges VS insimbi engagqwali flanges

I-Carbon steel iyingxube ye-iron-carbon alloy enokuqukethwe kwekhabhoni ephezulu nendawo encibilikayo ephansi kunensimbi engagqwali. I-Carbon steel iyafana ngokubukeka nezakhiwo zensimbi engagqwali, kodwa inokuqukethwe kwekhabhoni ephezulu.

Ubunjiniyela kanye nezinto zokwakha ezifana ne-carbon steel zivame ukusetshenziswa ezinqubweni ezinkulu zezimboni, ezihlanganisa ukuxhumana ngocingo, ezokuthutha, ukucutshungulwa kwamakhemikhali, nokukhipha nokucwengisiswa kwe-petroleum.

Kunezinhlobo eziningi zensimbi ezingabizwa ngokuthi ama-flange ensimbi engagqwali angu-304, kodwa zonke izinhlobo zensimbi zenziwe ngensimbi nekhabhoni kusetshenziswa inqubo enezinyathelo ezimbili. Lapho i-chromium ne-nickel yengezwa ensimbi engagqwali, ukumelana nokugqwala kuyatholakala.

UMEHLUKO PHAKATHI KWE-CARBON STEEL FLANGES KANYE NE-STAINLESS STEEL FLANGES
Ama-Forgings enziwe kusukela ku-A-105 amabanga ayizinto zokuqala nezivamile ezisetshenziselwa ukwenza ama-flange amapayipi. Kuzinhlelo zokusebenza ezidinga amazinga okushisa aphansi, amamaki A-350 LF2 asetshenziswa, kuyilapho amamaki A-694, F42-F70, enzelwe isivuno esiphezulu. Ngenxa yamandla akhulayo we-carbon steel flanges, impahla ekhiqiza kakhulu isetshenziswa kabanzi ekufakweni kwamapayipi.

Ngaphezu kokuqukatha i-chromium ne-molybdenum eningi kunama-flange ensimbi ye-carbon, ama-alloy steel flange aklanyelwe ukumelana nezinga lokushisa eliphezulu nezimo zengcindezi ephezulu. Ngenxa yokwanda kokuqukethwe kwe-chromium, anokuvikela ukugqwala okuqinile kunama-flange ensimbi ekhabhoni avamile.

Insimbi engagqwali equkethe i-nickel, i-chromium ne-molybdenum ingeyesibili evame ukusetshenziswa kakhulu ekukhiqizeni i-flange. Okuvame kakhulu ukukhohlisa kwe-ASTM A182-F304 / F304L kanye ne-A182-F316 / F316L kutholakala ochungechungeni lwe-A182-F300/F400. Ama-trace elements angengezwa phakathi nenqubo yokuncibilika ukuze kuhlangatshezwane nezidingo zesevisi zalawa makilasi omgunyathi. Ngaphezu kwalokho, uchungechunge lwama-300 aluwona uzibuthe kuyilapho uchungechunge lwama-400 lunezakhiwo kazibuthe futhi alukwazi ukumelana nokugqwala.
