Cov khoom siv ASME SB111 yog dab tsi?
ASME SB-111 yog tus qauv specification rau seamless tooj liab thiab tooj liab-alloy condenser raj thiab ferrule Tshuag, tus yam ntxwv los ntawm high thermal conductivity thiab corrosion kuj. Nws yog feem ntau yog siv rau cov cua kub exchangers, evaporators, thiab nto condensers nyob rau hauv fais fab nroj tsuag, roj refineries, thiab marine engineering daim ntaub ntawv.
C44300 U-Bend Tube Chaw tsim tshuaj paus
GNEEmuaj tshaj 18 xyoo ntawm kev xa tawm kev ua ke nrog kev tsim cov yeeb nkab siab heev thiab kev ua tiav U- khoov cov thev naus laus zis. Peb muab siab - zooASME SB111 C44300 U-khoov tooj liab alloy rajrau cov phiaj xwm kub exchanger thoob ntiaj teb. Peb cov khoom raug xa tawm mus rau ntau dua 80 lub teb chaws- suav nrog Kaus Lim Qab Teb, Saudi Arabia, UAE, Qatar, Is Nrias teb, Singapore, Indonesia, Nyab Laj, Brazil, South Africa, thiab Europe- pabcuam kev tsim hluav taws xob, petrochemical, shipbuilding, marine engineering, thiab HVAC industries.
PebASME SB111 C44300 U-khoov tooj liab alloy kub exchanger rajyog tsim los ntawm UNS C44300 Admiralty Brass (CuZn28Sn1). Cov tooj liab no -zinc- tin alloy muaj kwv yees li 70% -73% tooj liab thiab 0.9% -1.2% tin, nrog rau me me ntxiv ntawm arsenic los txhim kho nws cov kev tiv thaiv rau dezincification. Lawv tau tsim tshwj xeeb rau lub plhaub{11}}thiab- raj cua kub exchangers, condensers, evaporators, thiab marine cooling systems tuav dej tshiab, dej khib nyiab, los yog dej hiav txwv.
Thaum lub sij hawm U-bending txheej txheem ntawm C44300 hlab, tseem ceeb residual stress yog generated nyob rau hauv lub khoov cheeb tsam. Yog tias tsis kho, cov kev ntxhov siab no tuaj yeem ua rau cov khoom siv tiv thaiv corrosion thiab qaug zog ua haujlwm. Yog li ntawd, kev ntxhov siab-relief annealing yog siv rau ntawm qhov khoov thiab cov ntu ncaj uas nyob ib sab (extending yam tsawg kawg yog 150 mm ntawm txhua qhov tangent point). Qhov kev kho no txo qis kev pheej hmoo ntawm kev ntxhov siab corrosion cracking (SCC) thiab ua kom ntseeg tau, ntev - kev ua tau zoo nyob rau hauv thermal thiab siab cycling tej yam kev mob.
Piv rau cov qauv tooj dag, C44300 nta thermal conductivity ntawm 109 W / m·K (20 degree), xa cov45% nce nyob rau hauv tshav kub hloov efficiency tshaj stainless hlau. Thaum ua kom muaj kev ua tau zoo ntawm cov cua sov, nws tseem muaj qhov tshwj xeeb tiv thaiv pitting, yaig, thiab dezincification hauv cov dej txias txias, ua rau nws nyiam cov khoom siv hluav taws xob, refineries, desalination chaw, offshore platforms, thiab kev lag luam tshuaj.
