P265GH Pressure Vessel Steel Plate

P265GH Steel - e hanyetsanang le mocheso le e se nang motsoako

P265GH ke eng?
Kereiti ea P265GH ke Litšepe tsa Khatello ea Mocheso tse hanyetsanang le mocheso tse hlalositsoeng tsamaisong ea EN 10028. Ke tšepe e se nang alloy. Boitsebiso bo etselitsoe likopo tse phahameng tsa mocheso. Ka hona e sebelisoa haholo lits'ebetsong tsa mocheso o phahameng lefapheng la oli le khase, liindasteri tsa ts'ebetso ea lik'hemik'hale le makaleng a petrochemical.

Ke thepa e ka sehloohong ea ho etsa li-boilers le likepe tse hatelitsoeng. E tloaelehile ka ho e boloka khahlanong le mocheso oa 890 ho ea ho 950 ° C ntle le ho tšoara; ho futhumatsa ho fetisoa ka botenya ba poleiti.

EN 10028 ke eng?
P265GH e khetholloa ho EN 10028 e tloaelehileng. Ke tekanyetso ea thepa ea Europe bakeng sa "Lihlahisoa tsa Flat tse entsoeng ka litšepe bakeng sa merero ea khatello". Ho feta moo, maemo a koahela "Non-alloy le alloy steels tse nang le thepa e phahameng ea mocheso". Tekanyetso e phatlalalitsoe ka selemo sa 2009.

Hobaneng P265GH e bitsoa A516 grade 60 Steel?
P265GH ke motsoako oa mabitso ho latela maemo a Europe, hape o bitsoa A516 grade 60 ho litekanyetso tsa ASME/ASTM. Baetsi ba bangata ba ipolela hore ba lumellana le lintlha tse peli tsa EN 10028 le ASME/ ASTM thepa ea tšepe ea A516 grade 60.
