ASTM A423 Qib 1 Thaum tshav kub kub Exchanger / Condenser Tubesxa cov kev ua tau zoo nyob rau hauv siab - qhov chaw ua haujlwm kub. Cov qib alloy no qhia tau hais tias muaj kev tiv thaiv zoo heev hauv kev txo qis xws li raug chlorides, sulfides, alkalis, sulfuric acid, nitric acid, thiab lwm yam tshuaj lom neeg.
Nws muaj zog tiv thaiv corrosion thiab hnav. Tsis tas li ntawd, nws cov thermal expansion coefficient ua rau nws haum rau cryogenic thiab kub -sensitive daim ntaub ntawv, tso cai rau kub tswj tau yooj yim thiab stabilized. Cov khoom siv kuj tsis cuam tshuam los ntawm carbide nag lossis daus, ua kom ruaj khov ntev - lub sijhawm ua haujlwm.
Nyob rau hauv siab - cov kev mob siab, cov hlab no muaj kev sib khi zoo heev uas tsis muaj qhov xau. Lawv kuj muaj cov khoom tsim tau zoo tshaj plaws - lawv cov machinability zoo thiab formability pab txo cov nqi tsim khoom thiab kev ua haujlwm.
Txhua qhov khoom xa tuaj yog muab nrog cov ntaub ntawv tiav, suav nrog daim ntawv qhia tshwj xeeb, daim ntawv xa nyiaj lag luam, daim ntawv pov thawj cov khoom siv raw, cov ntawv ntim khoom, thiab daim ntawv tshaj tawm fumigation.

Cov tshuaj muaj pes tsawg leeg ntawm ASTM A423 Qib 1 yog dab tsi?
Cov tshuaj muaj nyob rau hauv A423 Gr 1 qib yog carbon, phosphorus, manganese, sulfur, tooj liab, thiab silicon. Cov ntsiab lus siab ntawm carbon, manganese, thiab sulfur muab kev txhim kho oxidation tsis kam, pitting tsis kam rau ib puag ncig acidic, crevice kuj, thiab kev ntxhov siab corrosion cracking kuj.
Dab tsi yog cov khoom siv SA 423?
ASTM A423 Weathering Steel Pipes Gr. 1 yog nrov siv hauv cov duab puab sab nraum zoov. ASTM A423 Corten Steel Tubes Qib 1 kuj tseem siv rau hauv choj thiab lwm yam kev siv loj. Cov tshuaj muaj nyob rau hauv Corten steel raj no yog carbon, phosphorus, manganese, sulfur, tooj liab, silicon.
Dab tsi yog qhov ntau thiab tsawg ntawm ASTM A423 kav?
ASTM A423 cov kav dej muaj nyob rau hauv ntau yam txheej sab nraud, phab ntsa tuab, thiab ntev, nyob ntawm seb lawv puas seamless lossis welded. Tus qauv npog nominal yeeb nkab qhov ntau thiab tsawg ntawm 1/8 nti mus rau 24 ntiv tes, nrog phab ntsa thickness thiab ntev sib txawv raws li daim ntawv thov.
Dab tsi yog cov yam ntxwv ntawm ASTM A423 kav dej?
Cov kav dej no yog tsim los rau siab -kev siv kub thiab yog li ntawd muaj zog tensile siab, yield zog, thiab creep kuj. Cov khoom muaj xws li lub zog tensile ntawm 415-550 MPa, yield zog ntawm 205-275 MPa, thiab elongation haum rau kev tsim thiab vuam. Tus nqi tseeb nyob ntawm seb cov yeeb nkab qib thiab phab ntsa thickness.
ASTM A423 cov kav dej feem ntau siv nyob qhov twg?
ASTM A423 kav dej yog dav siv hauv boilers, tshav kub exchangers, superheaters, thiab cov khoom siv fais fab nroj tsuag. Lawv yog cov zoo tagnrho rau cov kav dej uas nqa siab -kub chav, dej kub, los yog gases, qhov twg corrosion kuj thiab seem stability nyob rau hauv tshav kub yuav tsum tau.
