Seamless Boiler Steel Kav yog ib hom ntawm cov yeeb nkab seamless thiab nws feem ntau muab faib ua qis thiab nruab nrab siab boiler seamless yeeb thiab kub siab boiler seamless raj. Cov kav dej no tau paub txog lawv cov kev ua haujlwm siab zoo& endurance, thiab cov no muaj nyob nrog ntau yam kev cai raws li tus neeg yuav khoom.
Boiler kav tawm smoothpipesmade ntawm cov hlau, tsis muaj seam thiab ntau lub thicknesses, siv rau hauv kev lag luam rau cov hom phiaj dav dav EN 10216-1: 2005 (EX UNI 7287 / 86) lossis rau kev tsim cov kav dej yooj yim, xws li cov kav dej hla dej, dhau los uas lub zog ua los ntawm lub rhaub dej kub.
Cov qauv thiab cov khoom siv rau cov yeeb nkab steel yog muaj ntawm carbon, alloy, thiab tsis muaj cov khoom siv steel hlau.
Cov pa roj carbon steel: ASTM / ASME A / SA 106, ASTM A179, ASTM A192, ASTM / ASME A / SA 210, ASTM A333 Gr 1, 6,7 txog Gr 9,
Alloy hlau: ASTM / ASME A / SA 213 T1, T2, T5, T9, T11, T12, T22, T91, T92; ASTM A335 P1, P2, P5, P9, P11, P12, P22, P91, P92
Stainless hlau: ASTM A268, ASTM A213, TP304 / L, TP316 / L, 310S, 309S, 317,317L, 321,321H, thiab duplex stainless hlau khoom thiab lwm yam.
Qhov ntau thiab tsawg: OD los ntawm 6mm mus rau 1240mm, tuab los ntawm 1mm mus rau 50mm
Cov Ntaus: Ncaj boiler yeeb nkab, thiab U boiler steel yeeb rau raj xa pa raj ua ke.
Cov qauv no qhia meej txog kev faib tawm, qhov loj me, cov qauv, qhov hnyav thiab kev tso cai sib txawv, cov kev xav tau, kev tshuaj xyuas thiab kuaj, ntim, cim thiab cov ntawv pov thawj zoo ntawm cov hlau tsis muaj hau rau cov rhaub dej.
Boiler yeeb nkab loj ntau ua tau raws li qhov sib txawv ASTM tus qauv uas yuav tsum tau. Xws li ASTM A106 lossis ASTM 179, 192 thiab lwm yam.
Tab sis feem ntau ntawm cov raj xa dej yog qhov me me, sab hauv qhov dav feem ntau me dua li 1 1/2 "(1/4", 1/2 ", 3/4", 1 "thiab 1 1/2"). Tom qab ntawd 2 ", 2 1/2", 3 "thiab qhov siab tshaj plaws rau 4".
Raws li qhov sib txawv ua haujlwm kub, nruab nrab lossis siab siab boiler yeeb nkab yuav tsum siv. Feem ntau muab cais raws li cov hauv qab no:
a. Kev ua haujlwm kub ntawm lub rhaub dej kub dav dav yog qis dua 450 ℃. Lub nruab nrab siab boiler pipeline feem ntau adopts kub dov txheej txheem los yog txheej txheem yog nqus txias.
b. Lub tshuab cua kub siab boiler feem ntau siv rau qhov kub thiab txias siab. Raws li kev ua haujlwm ntawm qhov kub kub flue roj thiab chav rhaub, cov yeeb nkab yuav tshwm sim oxidation thiab corrosion. Nws yog qhov yuav tsum tau siab kub boiler yeeb nkab uas muaj lub zog ruaj khov, siab tiv thaiv oxidation thiab zoo nqaij kev ruaj ntseg.
