Nco tseg:Thaum cov qib no sib npaug ntau, tuaj yeem muaj qhov sib txawv me me hauv cov tshuaj muaj pes tsawg leeg txwv thiab cov khoom siv kho tshuab. Nco ntsoov paub meej nrog qhov project cov khoom tshwj xeeb xav tau.
Tshuaj muaj pes tsawg leeg
Qhov sib xyaw ua ke yog qhov tseem ceeb hauv nws qhov tsim nyog rau kev pabcuam siab -siab. Nws yog ibqis- carbon steelnrog tswj qib ntawm lwm cov ntsiab lus kom ntseeg tau zoo weldability thiab lub zog ntawm qhov kub thiab txias.
Ib qho piv txwv muaj pes tsawg leeg yog:
Cov pa roj carbon (C):0.10 - 0.18% (Cov pa roj carbon tsawg rau zoo weldability)
Manganese (Mn): 0.40 - 0.80%
Phosphorus (P):Tsawg dua los yog sib npaug rau 0.025% (Tsawg los tiv thaiv embrittlement)
Sulfur (S):Tsawg dua lossis sib npaug li 0.025% (Tsawg los txhim kho ductility thiab toughness)
Silicon (Si):~0.10 - 0.35% (Ntxiv lub zog thiab deoxidizes cov hlau)
Mechanical Properties
Cov khoom yog lav nyob rau hauv chav tsev kub thiab tsim kom ruaj khov nyob rau hauv lub sij hawm ntev - raug tshav kub.
Tensile zog:410 - 530 MPa (kwv yees . 59, 500 - 76,900 psi)
Yield zog (Min.):~ 255 MPa (kwv yees . 37,000 psi)
Elongation (Min.):~ 25% ( Qhia tau tias zoo ductility)
Cov yam ntxwv tseem ceeb thiab vim li cas nws thiaj siv rau boilers
High Pressure thiab Kub Resistance:Nws yog tsim tshwj xeeb los tiv thaiv cov kev kub ntxhov sab hauv thiab qhov kub thiab txias hauv boiler systems, superheaters, thiab kub exchangers (feem ntau txog ~ 450℃/ 840℃F).
Zoo heev Creep Strength:Creep yog qhov qeeb, mus tas li deformation ntawm cov khoom nyob rau hauv qhov kev ntxhov siab tas li ntawm qhov kub thiab txias . 1.0254/A192 muaj kev tiv thaiv zoo rau creep, txhais tau tias nws yuav tsis maj mam ncab lossis ua tsis tau ntau xyoo ntawm kev pabcuam.
Zoo Weldability thiab Formability:Cov ntsiab lus tsis tshua muaj carbon ua rau nws yooj yim rau vuam siv ntau txoj hauv kev yam tsis muaj qhov dav ua ntej - lossis tshaj tawm -weld kho cua sov, uas yog qhov tseem ceeb rau kev tsim thiab txhim kho cov tshuab boiler complex.
Kev ntseeg tau thiab kev nyab xeeb:Cov kav dej no tau tsim nyob rau hauv kev tswj hwm nruj, suav nrog tsis yog - kev kuaj kev puas tsuaj (xws li hydrostatic lossis ultrasonic kuaj) kom ntseeg tau tias lawv tsis muaj qhov tsis xws luag uas tuaj yeem ua rau muaj kev puas tsuaj loj.
Seamless Kev Tsim Kho:Boiler raj yuav luag txhua zausseamless(raws li DIN 17175 thiab ASTM A192), txhais tau tias lawv tau tho los ntawm cov khoom siv pob zeb. Qhov no tsim cov qauv zoo sib xws uas tsis muaj qhov ntev weld seam, uas yog qhov muaj peev xwm tsis muaj zog nyob rau hauv siab.
Cov ntawv thov siv
1.0254 / A192 cov kav dej yog siv txhua qhov chaw uas xav tau kom muaj dej los yog chav nyob hauv qhov kub thiab txias.
Siab -Boiler Tubes:Cov dej tseem ceeb- cov phab ntsa thiab cov raj boiler hauv cov pob txha roj hluav taws xob thiab cov boilers muaj.
Superheaters thiab Reheaters:Cov seem ntawm lub boiler uas ntxiv cov cua sov ua kom cov nroj tsuag efficiency.
Thaum tshav kub kub Exchangers:Hauv ntau cov txheej txheem kev lag luam.
Piping rau Saturated Steam:Kev thauj cov chav nyob hauv ib lub zog lossis cov txheej txheem.
