Seamless steel kav yog dav siv. Raws li kev siv sib txawv, muaj tuab-walled seamless steel kav thiab nyias-walled seamless steel kav.
1. Lub hom phiaj dav dav seamless steel kav yog dov los ntawm cov pa roj carbon zoo tib yam steel, cov hlau tsis tshua muaj hlau lossis hlau alloy steel raws li cov khoom siv. Piv txwv li, cov kav dej seamless ua los ntawm cov pa roj carbon tsawg xws li 10 # thiab 20 # feem ntau yog siv los ua cov kav dej xa mus rau chav dej, cov pa roj carbon monoxide, roj liquefied, nkev roj, ntau yam khoom siv roj av thiab lwm yam gases lossis kua; nruab nrab carbon steel xws li 45 thiab 40Cr Cov kav dej seamless tsim yog siv los tsim ntau yam tshuab thiab cov yeeb nkab fittings.
2. Seamless steel kav rau lub hom phiaj dav kuj tau muab raws li cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab, thiab raws li kev ntsuas hydraulic. Seamless steel kav uas dais dej siab yuav tsum dhau qhov kev ntsuas hydraulic.
3. Cov kav dej tshwj xeeb seamless yog siv rau hauv boilers, geological tshawb nrhiav, bearings, acid kuj, thiab lwm yam. xws li roj av geological drilling kav,cov kav dej tawgrau petrochemical kev lag luam,cov kav dej boiler, bearing pipes thiab high-precision structural steel kav rau tsheb, tsheb laij teb thiab aviation.
Cov kav dej seamless steel feem ntau yog siv rau cov qauv dav dav thiab cov khoom siv tshuab. Nws cov ntaub ntawv sawv cev (qib): carbon steel No. 20, No. 45 steel; hlau alloyq345 ua20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, thiab lwm yam.
Seamless steel kav rau thauj cov kua dej yog siv los thauj cov kav dej hauv engineering thiab cov khoom siv loj. Cov ntaub ntawv sawv cev (qib) yog 20, Q345, thiab lwm yam.
Seamless steel kav rau qis thiab nruab nrab siab boilers yog tsuas yog siv rau pipelines thauj uas tsis muaj thiab nruab nrab siab siab kua nyob rau hauv industrial boilers thiab domestic boilers. Cov ntaub ntawv sawv cev yog No. 10 thiab 20 # steel.
Seamless steel kav rau high-pressure boilers yog tsuas yog siv rau high-temperature thiab high-pressure kua thauj headers thiab kav dej nyob rau hauv fais fab nroj tsuag thiab nuclear fais fab nroj tsuag boilers. Cov ntaub ntawv sawv cev yog20 G, 12Cr1MoVG, 15CrMoG, thiab lwm yam.
Seamless steel kav rau cov khoom siv high-pressure fertilizer yog tsuas yog siv los thauj cov dej kub thiab kub siab rau cov khoom siv chiv. Cov ntaub ntawv sawv cev yog 20, 16Mn,12 CrMo, 12Cr2Mo, thiab lwm yam.
Seamless steel kav rau roj av tawg yog tsuas yog siv nyob rau hauv boilers, tshav kub exchangers thiab kua thauj pipelines nyob rau hauv roj av smelting nroj tsuag. Nws cov ntaub ntawv sawv cev yog 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, thiab lwm yam.
Seamless steel kav rau lub tog raj kheej roj yog siv los ua ntau yam roj thiab hydraulic roj thooj voos kheej kheej. Nws cov ntaub ntawv sawv cev yog 37Mn, 34Mn2V, 35CrMo, thiab lwm yam.
Kub dov seamless steel kav yog siv rau hydraulic props, uas yog tsuas yog siv los ua hydraulic kev txhawb nqa, lub tog raj kheej thiab txhua kab hauv cov mines thee, nrog rau lwm cov hydraulic thooj voos kheej kheej thiab kab. Nws cov ntaub ntawv sawv cev yog 20, 45, 27SiMn, thiab lwm yam.
Cold-drawn los yog txias-dov precision seamless steel kav yog tsuas yog siv rau cov khoom siv kho tshuab thiab cov khoom siv carbon pressing, yuav tsum muaj qhov tseeb qhov tseeb thiab qhov chaw zoo. Nws cov ntaub ntawv sawv cev suav nrog 20, 45 steel, thiab lwm yam.
Cold-drawn seamless steel kav thiab tshwj xeeb-shaped steel kav yog siv los ua ntau yam qauv thiab qhov chaw. Lawv yog ua los ntawm high-quality carbon structural steel thiab low-alloy structural steel.
Precision puab txoj kab uas hla seamless steel kav rau hydraulic thiab pneumatic thooj voos kheej kheej yog tsuas yog siv los ua txias-draw los yog txias-dov seamless steel kav nrog precision puab diameters rau hydraulic thiab pneumatic thooj voos kheej kheej. Nws cov khoom sawv cev yog 20, 45 steel, thiab lwm yam.
