DIN 17175 13CrMo44 seamless heat exchange tube yog ib hom tshwj xeeb ntawm seamless steel yeeb nkab tsim los rau kev sib pauv cua sov, ua raws li German kev lag luam tus qauv DIN 17175.
Ua haujlwm kub: 450 - 580 degree
Tawm lub zog (ntawm 20℃(piv txwv li chav tsev kub rau siv)): Ntau dua lossis sib npaug li 280 MPa
Tensile zog: 440 - 590 MPa
Elongation: Ntau dua lossis sib npaug li 20%
Kev pabcuam lub neej: tuaj yeem ua haujlwm ruaj khov rau ntau dua 100,000 teev nyob rau hauv siab -qhov kub thiab txias (nyob ntawm qhov ua haujlwm tiag tiag)

Daim ntawv thov hauv Heat Exchange:
Thawj qhov kev siv ntawm DIN 17175 13CrMo44 seamless heat exchangers yog nyob rau hauv cov cua kub exchangers, uas lawv pab txhawb kev hloov ntawm tshav kub ntawm ob lub kua. Qhov no tuaj yeem tshwm sim hauv ntau qhov chaw lag luam, xws li cov chaw tsim hluav taws xob, cov chaw tsim khoom, cov chaw tsim tshuaj, thiab HVAC systems.
Cov raj yog tsim los tiv thaiv cov corrosive thiab siab -kub tej yam kev mob feem ntau ntsib nyob rau hauv lub tshav kub pauv txheej txheem, ua kom ntseeg tau zoo thiab txhim khu kev qha tshav kub hloov mus rau lub sij hawm ntev.
