Pipe e se nang mohele ea tšepe ea carbon ea ASTM SA210 GrA – Khetho e Sebetsang hantle bakeng sa liboiler le li-exchange tsa mocheso

ASTM SA210 GrAke phaephe e se nang moedi ya tshepe ya khabone bakeng sa diboiler tsa kgatello e mahareng le e tlase le di-heat exchanger. E dumellana le maemo a American Society for Testing and Materials (ASTM). E na le kganyetso e ntle ya mocheso o phahameng, matla a ho hatella le tshebetso ya ho tjheseletsa. E sebediswa haholo ditsamaisong tsa tlhahiso ya diboiler le phapanyetsano ya mocheso diindastering tsa motlakase, tsa dikhemikhale, tsa peterole le tse ding.

ASTM SA210 GrAke tšepe e nang le khabone e tlase (C≤0.27%), e nang le likarolo tse kang manganese (Mn 0.93% max) le silicon (Si 0.10-0.20%) ho netefatsa thepa e ntle ea mechini le ho sebetsa habonolo.

Selefo le phosphorus tse tlase (P≤0.035%, S≤0.035%) li ntlafatsa khanyetso ea oxidation mochesong o phahameng.

Tshebetso e ntle haholo

Ho hanyetsa mocheso o phahameng: mocheso oa nako e telele oa ho sebetsa ≤450℃, nako e khuts'oane ho fihlela ho 480℃.

Ho bea khatello e phahameng: e loketse liphaephe tsa boiler tsa khatello e mahareng le e tlase ≤5.88MPa.

Ho lumellana ha ts'ebetso: ho bonolo ho e tjheseletsa, ho e koba le ho e bata, e loketse maqephe a li-boiler tube, lihlooho le likarolo tse ling.

Melao e tiileng

LatelaASTM SA210 GrAmaemo, le ho fetaGB/T 3087, ASME le mangolo a mang a netefatso ho netefatsa polokeho le botshepehi.

Phaephe ea tšepe e se nang moedi ea ASTM SA210 GrA ke khetho e ntle bakeng sa masimo a latelang:

Indasteri ea boiler: lebota la metsi a boiler, superheater, economizer le likarolo tse ling tsa bohlokoa.

Mochini o fetolang mocheso: liphaephe tsa condenser le evaporator indastering ea petrochemical.

Matla a motlakase: liphaephe tsa phetiso ea mouoane le litsamaiso tse thusang tsa lifeme tsa motlakase tse futhumatsang.

Katleho ea litšenyehelo: Ha li bapisoa le liphaephe tsa tšepe ea alloy, liphaephe tsa tšepe ea carbon tsa ASTM SA210 GrA li fokotsa litšenyehelo tsa theko haholo ha li ntse li fihlela litlhoko tsa ts'ebetso.

Phepelo e tsitsitseng: Jwalo ka thepa ya tube ya boiler e akaretsang, lenane la thepa la mmaraka le lekane mme potoloho ya ho pepa e kgutshwane.

Re fana ka tlhahlobo e ikhethileng ea ho seha, liteko tse sa senyeheng (UT/RT), tlaleho ea thepa le lits'ebeletso tse ling bakeng sa liphaephe tsa tšepe tse se nang sekoli tsa ASTM SA210 GrA, 'me re tšehetsa kabo ea thepa ea lefats'e.

ASTM SA210 GrAPhaephe e se nang moedi ya tshepe ya khabone e fetohile sehlahiswa sa boleng bo hodimo lefapheng la diboiler le di-heat exchanger ka lebaka la tshebetso ya yona e tsitsitseng le moruo. Haeba o hloka di-parameter tsa tekheniki kapa khotheishene, ka kopo ikopanye le sehlopha sa rona sa ditsebi!
