Dab tsi yog DIN 17175 khoom?
DIN 17175: German kev lag luam tus qauv, tshwj xeeb tshaj yog tsim los rau cov cua sov- resistant steel boiler raj, haum rau boiler cua sov nto Cheebtsam (xws li economizers thiab superheaters) nrog rau kev ua hauj lwm pressures tsawg tshaj li los yog sib npaug rau 5.88MPa (tsawg / nruab nrab siab) kom siab tshaj los yog sib npaug zos rau 9.8MPa (siab siab peculiarity) thiab kub siab. cov kav dej.
