St35.8 boiler steel tubes yog rau cov carbon structural steel qeb ntawm German DIN tus qauv. Lawv cov tshuaj muaj pes tsawg leeg muaj cov ntsiab lus carbon tswj ntawm 0.17% thiab 0.24%, silicon cov ntsiab lus ntawm 0.10% thiab 0.35%, thiab manganese cov ntsiab lus ntawm 0.40% thiab 0.80%, thaum tswj cov ntsiab lus ntawm cov teeb meem xws li sulfur thiab phosphorus. Qhov kev tshawb fawb muaj pes tsawg leeg no muab cov khoom zoo heev yas deformation muaj peev xwm thiab weldability.
Specification
St35.8 Khoom Paub meej: Cov yeeb nkab steel rau German boilers thiab cov hlab ntsha siab, ua raws li DIN 17175 tus qauv:
Chemical Composition: Cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.17%, Manganese cov ntsiab lus 0.40-1.20%
Mechanical Properties: Tensile zog 360-480MPa, lav qhov kub thiab txias tawm los lub zog
Cov Kev Xav Tau Tshwj Xeeb: Kev kuaj Hydrostatic thiab kuaj ultrasonic yog yuav tsum tau.
Daim ntawv thov
St35.8 seamless steel kav, vim lawv qhov siab - kub thiab siab - siab tsis kam, feem ntau yog siv rau hauv cov xwm txheej hauv qab no:
Ua ntej, nyob rau hauv lub boiler manufacturing kev lag luam, lawv yog siv los tsim cov khoom tseem ceeb xws li superheater raj, reheater tubes, thiab cov kav dej rau ntau yam boilers;
Thib ob, nyob rau hauv kev lag luam petrochemical, lawv tau siv los thauj cov siab - kub thiab siab - cov roj thiab cov pa tawm;
Thirdly, nyob rau hauv kev lag luam fais fab, lawv tau siv nyob rau hauv lub cua sov nto piping systems ntawm fais fab nroj tsuag boilers.
Tsis tas li ntawd, lawv tau siv dav hauv kev tsim khoom, kev lag luam tsheb, thiab lwm yam. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho ntawm supercritical chav boilers, St35.8 seamless steel kav yog ib tug irreplaceable cov ntaub ntawv vim hais tias lawv tswj kev ua tau zoo txawm nyob rau hauv kub txog li 570 degree.
