Umbhobho ongenamthungo we-ASTM SA210 GrA Carbon Steel – Ukhetho oluSebenzayo kwiiBoilers nakwi-Heat Exchangers

I-ASTM SA210 GrAyipayipi engenamthungo yentsimbi yekhabhoni kwiibhoyila ezinoxinzelelo oluphakathi noluphantsi kunye nezitshintshi zobushushu. Ihambelana nemigangatho ye-American Society for Testing and Materials (ASTM). Inokumelana okugqwesileyo nobushushu obuphezulu, amandla okucinezelwa kunye nokusebenza kwe-welding. Isetyenziswa kakhulu kwimveliso yeebhoyila kunye neenkqubo zokutshintshiselana ngobushushu kumashishini anamandla, amakhemikhali, ipetroliyam kunye namanye amashishini.

I-ASTM SA210 GrAyintsimbi ekhabhoni ephantsi (C≤0.27%), equlethe izinto ezifana ne-manganese (Mn 0.93% max) kunye ne-silicon (Si 0.10-0.20%) ukuqinisekisa iipropati ezilungileyo zoomatshini kunye nokusebenziseka lula.

Umxholo ophantsi wesalfure kunye ne-phosphorus (P≤0.035%, S≤0.035%) uphucula ukumelana ne-oxidation kubushushu obuphezulu.

Ukusebenza kakuhle kakhulu

Ukumelana nobushushu obuphezulu: ubushushu bokusebenza bexesha elide ≤450℃, okwethutyana elifutshane ukuya kuthi ga kwi-480℃.

Ukuthwala koxinzelelo oluphezulu: ifanelekile kwiipayipi zebhoyila ezinoxinzelelo oluphakathi noluphantsi ≤5.88MPa.

Ukuhambelana kwenkqubo: kulula ukuyishibiliza, ukuyigoba kunye nenkqubo yokubanda, ifanelekile kwiishiti zeetyhubhu zebhoyila, iintloko kunye nezinye izinto.

Imigangatho engqongqo

Hamba ngokweI-ASTM SA210 GrAimigangatho, kwaye ipasiseGB/T 3087, i-ASME kunye nezinye iziqinisekiso zokuqinisekisa ukhuseleko kunye nokuthembeka.

Umbhobho wentsimbi engenamthungo we-ASTM SA210 GrA lukhetho olufanelekileyo kwezi ndawo zilandelayo:

Ishishini lebhoyila: udonga lwamanzi ebhoyila, i-superheater, i-economizer kunye nezinye izinto ezibalulekileyo.

Umtshintshi wobushushu: imibhobho ye-condenser kunye ne-evaporator kushishino lwe-petrochemical.

Amandla ombane: imibhobho yokuhambisa umphunga kunye neenkqubo ezincedisayo zezityalo zamandla obushushu.

Ukusebenza kakuhle kweendleko: Xa kuthelekiswa nemibhobho yentsimbi ye-alloy, imibhobho yentsimbi yekhabhoni ye-ASTM SA210 GrA inciphisa kakhulu iindleko zokuthenga ngelixa ihlangabezana neemfuno zokusebenza.

Ubonelelo oluzinzileyo: Njengesixhobo setyhubhu yebhoyila ngokubanzi, uluhlu lwemarike lwanele kwaye umjikelo wokuhambisa umfutshane.

Sinikezela ngovavanyo lokusika olulungiselelwe wena, olungonakalisiyo (UT/RT), ingxelo yezinto eziphathekayo kunye nezinye iinkonzo zemibhobho yentsimbi engenamthungo ye-ASTM SA210 GrA, kwaye sixhasa ukusasazwa kwezinto kwihlabathi liphela.

I-ASTM SA210 GrAUmbhobho ongenamthungo wentsimbi yekhabhoni uye waba yimveliso esemgangathweni kwicandelo leebhoyila kunye nezitshintshi zobushushu ngenxa yokusebenza kwayo okuzinzileyo kunye noqoqosho. Ukuba ufuna iiparameter zobugcisa okanye ikowuteshini, nceda unxibelelane neqela lethu leengcali!
