K11578 Seamless Steel Yeeb Nkab

Summary / Teb ceev

K11578yog cov khoom siv qib tsim los ntawm covKS (Korean Industrial Standards)rau acarbon steel tubesiv rausiab -kev pabcuam kub. A Seamless Steel Yeeb Nkabtsim los rau tus qauv no yog cov yeeb nkab uas tsis muaj welded seam, ua rau nws muaj zog thiab zoo ib yam, haum rau siab -siab thiab siab- kub daim ntawv thov xws li boilers, tshav kub exchangers, thiab superheater raj hauv fais fab nroj tsuag.

Cov ncauj lus kom ntxaws

1. K11578 - Cov Khoom Siv Txheem

KS:Sawv rauKorean Industrial Standards, zoo ib yam li ASTM hauv Asmeskas, JIS hauv Nyij Pooj, lossis DIN hauv Tebchaws Yelemees.

K11578:Qhov no yog tus naj npawb tshwj xeeb. Nws yog Korean sib npaug rau lwm qhov zoo -paub thoob ntiaj teb cov qauv.

Direct sib npaug: ASTM A210 Qib A1(USA)

Kaw qhov sib npaug: JIS G3461 STBA12(Nyiv),DIN 17175 St 35.8(Lub teb chaws Yelemees).

Daim ntawv thov:Cov qauv no qhia txog cov kev xav tau rauseamless carbon steel raj rau boiler thiab superheater daim ntaub ntawv. Qhov no txhais tau tias cov hlau yog tsim los tswj nws lub zog thiab tiv thaiv oxidation (scaling) ntawm qhov kub siab.

Cov tshuaj muaj pes tsawg leeg ntawm K11578:

Cov pa roj carbon (C): ~0.10-0.20%

Manganese (Mn): ~0.30-0.80%

Silicon (Si):Ntau dua lossis sib npaug li 0.25%

Phosphorus (P):Tsawg dua lossis sib npaug li 0.035%

Sulfur (S):Tsawg dua lossis sib npaug li 0.035%

Tej yam khoom siv tshuab:

Tensile zog:~ 415 MPa (min)

Yield zog:~ 255 MPa (min)

Elongation:~ 30% (min)

2. Seamless Steel Yeeb Nkab - Yam khoom

Seamless (SMLS):Cov yeeb nkab no yog tsim los ntawm kev tho lub pob zeb ntawm cov hlau los tsim lub plhaub hollow, uas yog tom qab ntawd elongated thiab dov mus rau qhov xav tau loj thiab phab ntsa tuab.

Cov txiaj ntsig tseem ceeb:

Tsis muaj Seam:Qhov tsis muaj weld seam tshem tawm qhov muaj peev xwm tsis muaj zog, ua kom muaj zog.

Uniform Strength:Nws muaj cov qauv zoo ib yam nyob ib puag ncig nws tag nrho ib ncig.

Zoo dua rau Siab:Withstands siab dua sab hauv thiab sab nraud.

Kev ntseeg tau:Nyiam rau cov ntawv thov tseem ceeb uas tsis ua haujlwm tsis yog qhov kev xaiv.

Cov ntawv thov siv

Cov kav dej ua rau tus qauv K11578 yog siv rau hauv cov tshuab ua haujlwm ntawm qhov kub thiab txias. Common siv muaj xws li:

Boiler Tubes:Cov hlab hauv lub boiler uas dej hloov mus rau chav.

Superheater Tubes:Cov raj uas ntxiv cov cua sov rau qhov kub siab dua rau kev txhim kho kev ua haujlwm.

Thaum tshav kub kub Exchangers:Qhov twg cov kua dej kub hloov cov cua sov mus rau cov kua dej txias.

Fais fab Generation Plants:Fossil roj thiab biomass fais fab chaw nres tsheb.

Petrochemical cog:Nyob rau hauv ntau yam txheej txheem cua sov units.

Kev yuav khoom thiab Specification

Thaum xaj lossis nug txog "K11578 Seamless Steel Yeeb Nkab," koj yuav tsum qhia ntau qhov tseem ceeb kom paub tseeb tias koj tau txais cov khoom raug:

Txheem:KS K11578

Hom:Seamless (SMLS)

Qhov Loj:

Sab nraud txoj kab uas hla (OD):eg, 50 mm, 2 nti, 60.3 mm, thiab lwm yam.

Phab ntsa Thickness (WT):eg, SCH 40, 3.5 mm, thiab lwm yam.

Ntev:Random lossis ruaj (piv txwv li, 6 meters, 20 ko taw).

Delivery condition:Feem ntau muab nyob rau hauv lub normalized los yog annealed cua sov- kho mob kom ua tau raws li qhov yuav tsum tau txhua yam khoom.

Ntawv pov thawj:Nws yog ib qho kev thov ibMill Test Certificate (MTC)los yogMaterial Test Report (MTR)uas tau lees paub cov tshuaj thiab cov khoom siv kho tshuab ntawm cov yeeb nkab batch ua raws li tus qauv K11578.
