Cov yeeb nkab hlau tsis muaj qhov sib txuas rau cov boilers yog ib hom yeeb nkab boiler thiab yog ib feem ntawm cov yeeb nkab hlau tsis muaj qhov sib txuas. Txoj kev tsim khoom zoo ib yam li cov yeeb nkab hlau tsis muaj qhov sib txuas, tab sis muaj cov kev cai nruj rau hom hlau siv rau hauv kev tsim cov yeeb nkab hlau. Cov yeeb nkab hlau tsis muaj qhov sib txuas rau cov boilers feem ntau siv rau hauv qhov kub thiab txias siab. Nyob rau hauv qhov kev ua ntawm cov pa roj kub thiab cov pa dej kub, cov yeeb nkab yuav oxidize thiab corrode. Cov yeeb nkab hlau yuav tsum muaj lub zog ntev, tiv taus oxidation thiab corrosion, thiab ruaj khov zoo. Cov yeeb nkab hlau tsis muaj qhov sib txuas rau cov boilers feem ntau yog siv los ua cov yeeb nkab siab, cov yeeb nkab pa loj, thiab lwm yam.

Cov raj boiler siab qis thiab nruab nrabGB3087 thiabboiler seamless rajGB5310 yog cov ntaub ntawv zoo siv los tsim cov kav dej kub heev, cov kav dej npau rau cov boilers siab qis ntawm ntau yam qauv, cov kav dej kub heev rau cov boilers locomotive, cov kav dej haus luam yeeb loj, cov kav dej haus luam yeeb me me thiab cov kav dej cib. Cov hlau carbon steel kub dov thiab txias kos (dov) seamless steel kav dej.Cov yeeb nkab hlau tsis muaj hlua (GB/T8162)yog cov yeeb nkab hlau tsis muaj seamless siv rau cov qauv dav dav thiab cov qauv kho tshuab.Cov kav dej boiler siab ASME SA-106 (GR.B, GR.C)thiabASTM A210siv rau cov kav dej boiler thiab cov nplaim boiler. Cov raj, suav nrog kev nyab xeeb kawg vault thiab strut raj thiab phab ntsa me me thickness seamless nruab nrab carbon steel raj rau superheater raj,ASME SA-213, seamless ferritic thiab austenitic rau boilers, superheaters thiab cov cua sov exchangers Alloy steel yeeb nkab,ASTM A335 P5, P9, P11, P12, P22, P9, P91, P92, ferritic alloy seamless steel yeeb nkab rau qhov kub thiab txias.

Cov lus qhia tshwj xeeb thiab qhov zoo ntawm cov tsos: GB5310-2017 "Cov Yeeb Nkab Hlau Tsis Muaj Qhov Txuas Rau Cov Boilers Siab" Lub cheeb tsam sab nraud ntawm cov yeeb nkab kub dov yog 22 txog 530 hli, thiab phab ntsa tuab yog txij li 20 txog 70 hli. Lub cheeb tsam sab nraud ntawm cov yeeb nkab txias rub (txias dov) yog txij li 10 txog 108 hli, thiab phab ntsa tuab yog txij li 2.0 txog 13.0 hli.

Cov kav dej seamless rau cov boilers txais cov qib hlau

(1) Cov qib hlau zoo uas muaj cov pa roj carbon zoo suav nrog 20G, 20MnG, thiab 25MnG.

(2) Cov hlau sib xyaw ua ke hlau qib15MoG, 20MoG, 12CrMoG,15CrMoG, 12Cr2MoG, 12CrMoVG, thiab lwm yam.
