Chitoliro Chopanda Msoko cha ASTM SA210 GrA Carbon Steel – Njira Yabwino Yogwiritsira Ntchito Maboiler ndi Zosinthira Kutentha

ASTM SA210 GrANdi chitoliro chopanda chitsulo cha kaboni chomwe chimapangidwa ndi ma boiler apakati ndi otsika komanso osinthira kutentha. Chimagwirizana ndi miyezo ya American Society for Testing and Materials (ASTM). Chimalimbana bwino ndi kutentha kwambiri, mphamvu yokakamiza komanso magwiridwe antchito owotcherera. Chimagwiritsidwa ntchito kwambiri popanga ma boiler ndi makina osinthira kutentha m'mafakitale amphamvu, mankhwala, mafuta ndi mafakitale ena.

ASTM SA210 GrAndi chitsulo chotsika cha kaboni (C≤0.27%), chomwe chili ndi zinthu monga manganese (Mn 0.93% max) ndi silicon (Si 0.10-0.20%) kuti zitsimikizire kuti makinawo ali ndi mphamvu komanso kuti zinthuzo zingagwiritsidwe ntchito bwino.

Kuchuluka kochepa kwa sulfure ndi phosphorous (P≤0.035%, S≤0.035%) kumathandizira kukana kutentha kwambiri.

Kuchita bwino kwambiri

Kukana kutentha kwambiri: kutentha kwa ntchito kwa nthawi yayitali ≤450℃, kwakanthawi kochepa mpaka 480℃.

Chotengera cha kuthamanga kwambiri: choyenera mapaipi a boiler apakati ndi otsika ≤5.88MPa.

Kugwirizana kwa njira: njira yosavuta kupotoza, kupindika ndi kuzizira, yoyenera mapepala a boiler tube, mitu ndi zinthu zina.

Miyezo yokhwima

TsatiraniASTM SA210 GrAmiyezo, ndi kuvomerezaGB/T 3087, ASME ndi ziphaso zina kuti zitsimikizire chitetezo ndi kudalirika.

Chitoliro chachitsulo chopanda msoko cha ASTM SA210 GrA ndi chisankho chabwino kwambiri pazigawo zotsatirazi:

Makampani a boiler: khoma la madzi a boiler, superheater, economizer ndi zigawo zina zofunika.

Chosinthira kutentha: mapaipi a condenser ndi evaporator mumakampani opanga petrochemical.

Mphamvu yamagetsi: mapaipi otumizira nthunzi ndi machitidwe othandizira a zomera zamagetsi zotentha.

Kugwiritsa Ntchito Ndalama Moyenera: Poyerekeza ndi mapaipi achitsulo cha alloy, mapaipi achitsulo cha carbon a ASTM SA210 GrA amachepetsa kwambiri ndalama zogulira pamene akukwaniritsa zofunikira pakugwira ntchito.

Kupereka kokhazikika: Monga zinthu zonse za chubu cha boiler, zinthu zomwe zili pamsika ndizokwanira ndipo nthawi yotumizira ndi yochepa.

Timapereka njira zodulira mwamakonda, zoyesera zosawononga (UT/RT), lipoti la zinthu ndi ntchito zina za mapaipi achitsulo osapindika a ASTM SA210 GrA, komanso timathandizira kugawa kwa zinthu padziko lonse lapansi.

ASTM SA210 GrAChitoliro chopanda msoko cha chitsulo cha kaboni chakhala chinthu chofunikira kwambiri pa ntchito za ma boiler ndi zosinthira kutentha chifukwa cha magwiridwe ake okhazikika komanso osawononga ndalama zambiri. Ngati mukufuna magawo aukadaulo kapena mtengo, chonde lemberani gulu lathu la akatswiri!
