Kev Taw Qhia
Thoob plaws Tebchaws Europe thiab thoob ntiaj teb boiler, heat exchanger, pressure vessel thiab petrochemical process piping sectors,EN 10216yog tus qauv European uas siv dav tshaj plaws rau cov kav hlau tsis muaj seamless rau lub hom phiaj siab. Ntawm txhua qib,P235GHthiabP265GH— ob qib kub siab uas tsis yog hlau ua los ntawm cov hlau alloy — muab kev ua tau zoo sib xws tab sis muaj qib sib txawv. Kev xaiv qib tsis raug cuam tshuam ncaj qha rau tus nqi ntawm qhov project thiab kev nyab xeeb ntawm kev ua haujlwm.
Ua ib lub tuam txhab tsim cov kav hlau rau kev lag luam, SANONPIPE tswj hwm cov khoom muag tag nrho ntawm EN 10216 series seamless kav uas npog txhua qib tsis yog hlau thiab hlau sib xyaw. Tsab xov xwm no rhuav tshem qhov sib txawv tseem ceeb ntawm P235GH thiab P265GH, thiab piav qhia txog cov chaw kuaj xyuas tseem ceeb los muab cov lus qhia meej rau cov pab pawg engineering thiab kev yuav khoom.
Kev Txheeb Xyuas Txog EN 10216 Tus Qauv
EN 10216Cov kav hlau tsis muaj zog rau kev siv siabyog ib qho txheej txheem European uas teev cov xwm txheej kev xa khoom rau cov kav dej siab tsis muaj qhov tsis sib xws hla ntau qhov kub thiab txias. Nws tau teeb tsa ua ntau ntu:
- EN 10216-1Cov kav hlau tsis yog hlau uas muaj cov khoom kub hauv chav tshwj xeeb, qib zoo TR1/TR2, rau kev siv siab dav dav
- EN 10216-2Cov kav hlau tsis yog hlau thiab hlau sib xyaw rau kev pabcuam kub siab, GH qib zoo, rau cov boilers, cov khoom hloov cua sov thiab cov ntawv thov kub siab
