Taub qab Weld Flanges yog hom nrov tshaj plaws ntawm kev kub siab pipeline flange. Lub taub hau tsim ntawm pob tw ntawm pob tw weld flanges muab ib qho kev sib txuas muaj zog heev, thiab pob tw weld flanges tuaj yeem ua tau ntau yam tsis muaj cov ntaub ntawv sib cuam tshuam thiab muaj / lossis kev sib txuas zoo. Taub qab Weld Flanges tseem muaj qhov zoo dua ntawm kev ua tau zoo rau huab siab siab thiab qis.

Siv cov hlua S31803 DupleX steel yeeb nkab flanges ua kom muaj kev ua tau zoo, siab dua lub neej kev ua haujlwm. Vim tias dual xwm ntawm Austenitic thiab Ferritic Micrtructures tam sim no nyob rau hauv vaj huam sib luag, cov theem kub thiab ob sab flange cov khoom siv ntawm ob qho tib si steels.

ASME B16.5 WN \ / LWN \ / Yog li \ /

Cov kev loj-lub zog flanges muab kaw cia ntawm ntau yam kav dej kav dej. Folifunctional flange qhia zoo ruaj ruaj thiab cov khoom pov thawj txhim kho kom tsis txhob muaj chloride pitting hauv cov ntawv thov marine. Nrog cov qauv vuam cov txheej txheem, Super Duplex Flanges tuaj yeem muab tso rau yooj yim rau cov raj xa khoom sib txawv.

Duplex 2205, tsis yog S32205, yog cov khoom siv stainless hlau uas muaj cov microstructure muaj sib npaug muaj sib npaug ntawm cov ferrite thiab austenite. Cov qib no yog hom nrov tshaj plaws, thiab ob hom khoom siv ob-theem no yog qhov tseem ceeb tshaj 316 stainless hlau nyob rau hauv cov nqe lus muaj zog thiab corrosion tsis kam.

Cov hlau dua lub lag luam tau qhia rau kev ua lag luam raws li kev ua haujlwm cuam tshuam nrog cov teeb meem kev ntxhov siab uas tshwm sim los ntawm chlorine daws teeb meem. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom siv dullex flange kuj ua rau cov flanges tsawg dua rau cov chlorine-ntxias pitting corrosion. Cov alloys no tsis tshua kim dua li cov hlau uas muaj menyuam yaus npib tsib xee.
