ASTM A179 Kub Exchanger Tube
Khoom siv
ASTM A179 yog tus qauv kev qhia tshwj xeeb rau seamless txias-kos qis- carbon steel tubs tshwj xeeb tsim los rau cov khoom siv hluav taws xob sib hloov, condensers, thiab cov cuab yeej hloov hluav taws xob zoo sib xws. Cov raj no tau paub txog lawv cov thermal conductivity zoo heev thiab tau siv dav hauv kev lag luam uas hloov pauv hluav taws xob yog qhov tseem ceeb.
Specification
ASTM A179 raj yog tsim los ua kom tau raws li cov qauv nruj, kom ntseeg tau tias lawv tuaj yeem tiv taus qhov kub thiab txias. Cov kev qhia tshwj xeeb npog seamless txias-kos qis- cov pa roj carbon steel raj nrog qhov tsawg kawg nkaus phab ntsa tuab rau siv hauv tubular heat exchangers, condensers, thiab cov khoom siv hluav taws xob zoo sib xws.
Ntsiab nta
Seamless Kev Tsim Kho: Ua kom muaj kev sib haum xeeb thiab lub zog, txo qhov kev pheej hmoo ntawm kev xau thiab tsis ua haujlwm.
Txias-Drawn txheej txheem: Txhim kho qhov tseeb qhov tseeb thiab qhov chaw tiav, muab cov khoom siv kho kom zoo dua qub.
Cov ntsiab lus carbon tsawg: Txhim kho weldability thiab txo qhov kev pheej hmoo ntawm carbide nag lossis daus.
High Thermal conductivity: Zoo tagnrho rau kev siv hluav taws xob hloov pauv tau zoo.
Corrosion Resistance: Haum rau ib puag ncig uas tiv thaiv corrosion yog ib qho kev txhawj xeeb.

Qib Steel
ASTM A179 yog qib qis- carbon steel qib uas yog tsim tshwj xeeb rau cov cua kub exchanger thiab condenser raj. Nws cov ntsiab lus carbon tsawg ua kom zoo weldability thiab txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum vuam. Cov txheej txheem txias - rub tawm txhim kho nws cov khoom siv kho tshuab, ua rau nws tsim nyog rau kev siv siab - siab. Cov qib steel paub txog nws cov thermal conductivity, ua rau nws zoo tagnrho rau kev hloov cov cua sov.
Daim ntawv thov
ASTM A179 raj tau dav siv hauv:
Thaum tshav kub kub Exchangers: Rau kev hloov pauv kub ntawm cov kua.
Condenser: Hauv cov chaw tsim hluav taws xob thiab cov tub yees.
Boilers: Rau chav tsim thiab cua sov rov qab.
Kev ua tshuaj lom neeg: Hauv cov khoom siv uas muaj kev tiv thaiv corrosion thiab thermal conductivity yog qhov tseem ceeb.
Cov qhab nia xaiv tau
ASTM A192 Cov Lus Qhia Tshwj Xeeb: Zoo ib yam li A179 tab sis nrog cov ntsiab lus carbon ntau dua, tsim nyog rau kev siv siab - siab.
