Cov phaj muaj nyob rau hauv peb qib uas muaj zog sib txawv: Qib 60; Qib 65; thiab Qib 70. Cov hlau yuav tsum raug tua thiab ua rau kev xyaum ua austenitic ntxhib. Cov hlau yuav tsum ua raws li cov kev cai tshuaj tau teev tseg. Kev ntsuas nruj yuav tsum tau ua kom ua raws li cov kev xav tau teev tseg.
Scope
1.1 Qhov specification2 no suav nrog carbon-silicon steel daim hlau feem ntau rau nruab nrab- thiab siab dua-kub kev pabcuam hauv welded boilers thiab lwm cov hlab ntsha siab.
1.2 Daim phiaj raws li qhov tshwj xeeb no muaj nyob rau hauv peb qib uas muaj qib sib txawv raws li hauv qab no:
Qib US [SI]
Tensile zog, ksi [MPa]
60 [415]
60–80 [415–550]
65 [450]
65–85 [450–585]
70 [485]
70–90 [485–620]
1.3 Qhov siab tshaj plaws thickness ntawm daim hlau tsuas yog txwv los ntawm lub peev xwm ntawm cov muaj pes tsawg leeg kom tau raws li cov kev cai ntawm cov cuab yeej cuab tam.
1.4 Rau cov phaj uas ua los ntawm cov kauj thiab cov rooj tog tsis muaj kev kho cua sov lossis nrog kev ntxhov siab nkaus xwb, cov kev xav tau ntxiv, suav nrog cov kev xav tau ntxiv thiab kev tshaj tawm cov txiaj ntsig kev xeem ntxiv, ntawm Specification A20 / A20M siv.
1.5 Qhov tseem ceeb 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.
1.6 Cov txheej txheem thoob ntiaj teb no tau tsim los ua raws li cov txheej txheem thoob ntiaj teb lees paub txog kev tsim qauv tsim hauv Kev Txiav Txim ntawm Cov Ntsiab Cai rau Kev Txhim Kho Cov Txheej Txheem Thoob Ntiaj Teb, Cov Lus Qhia thiab Cov Lus Pom Zoo los ntawm World Trade Organization Technical Barriers to Trade (TBT) Committee.
