1.1 Cov lus qhia no suav nrog ntau qib ntawm qhov tsawg kawg nkaus-phab ntsa-thickness, seamless, carbon-molybdenum alloy-steel, boiler thiab superheater raj.
1.2 Qhov kev qhia tshwj xeeb no suav nrog cov raj 1 ⁄ 2 txog 5 nyob rau hauv. [12.7 txog 127mm] suav nrog, sab nraud txoj kab uas hla thiab 0. , suav nrog, hauv qhov tsawg kawg nkaus phab ntsa thickness.
1.3 Ib qho kev xaiv ntxiv uas yuav tsum tau muaj thiab, thaum xav tau, yuav tsum tau teev nyob rau hauv qhov kev txiav txim.
1.4 Cov txiaj ntsig tau teev nyob rau hauv ib nti-phaus units lossis SI units yuav tsum raug suav tias yog tus qauv. Nyob rau hauv cov ntawv nyeem, SI units tau qhia nyob rau hauv brackets. Cov nqi teev nyob rau hauv txhua qhov system tsis yog qhov sib npaug; Yog li ntawd, txhua qhov system yuav tsum tau siv nws tus kheej ntawm lwm tus. Kev sib xyaw cov txiaj ntsig los ntawm ob lub tshuab tuaj yeem ua rau tsis ua raws li qhov tshwj xeeb. Cov inch-phaus units yuav tsum siv tshwj tsis yog qhov "M" tsim ntawm qhov kev qhia tshwj xeeb no tau teev tseg hauv qhov kev txiav txim.
