Qib B suav rau feem coob ntawmA53kev txiav txim muab tso rau thoob ntiaj teb, feem ntau vim tias nws lub zog siab dua tso cai rau cov phab ntsa nyias nyias ntawm qhov sib npaug ntawm qhov ntsuas siab - cov khoom siv ncaj qha - nqi kom zoo dua ntawm kev txiav txim loj.
Ib feem ntawm Spec Feem ntau cov neeg yuav hla: Hom ntawv
A53 tsis yog ib yam khoom. Tus txheej txheem txhais tau peb hom kev tsim khoom, thiab sib xyaw ua ke ntawm kev yuav khoom yog ib qho ntawm cov khoom tsis raug ntau tshaj plaws uas peb pom dua thoob plaws lub khw.
- Hom S (Seamless):Pierced thiab dov los ntawm ib tug khoom billet, tsis muaj weld seam txhua. Siv qhov chaw uas yuav tsum tau ua kom muaj homogeneous phab ntsa.
- Hom E (Electric{0}}Resistance Welded):Coil steel tsim rau hauv ib lub raj thiab welded raws ib leeg longitudinal seam siv hluav taws xob tiv thaiv tam sim no. Qhov no yog txoj kev tsim khoom tseem ceeb rau A53 hnub no vim tias nws tuav nruj dua qhov ntev ntev ntawm tus nqi qis dua li Hom S.
- Hom F (Lub qhov cub-Butt Welded, Nruam Weld):Cov laus dua, qis dua - tus nqi txheej txheem txwv rau cov kab me me thiab Qib A nkaus xwb. Hom F tsis tshua muaj nyob sab nraud ntawm cov laj kab tshwj xeeb thiab qis - cov ntawv thov siab.
Daim ntawv xaj uas yooj yim hais tias "ASTM A53 yeeb nkab" yam tsis muaj tsab ntawv tawm ntawm lub zeb los txiav txim siab, uas yog raws nraim li cas ib qhov project xaus nrog txuas ntxiv -weld yeeb nkab ntawm ib txoj hauj lwm uas xav tias hluav taws xob-kuj- cov khoom siv welded.
Nyeem Daim Ntawv Qhia Tag Nrho
Qhov ua tiav, tsis paub meej A53 callout zoo li no:ASTM A53 Hom E, Qib B, NPS 6, Teem sijhawm 40, Dub
Txhua ntu muaj lub ntsiab lus sib txawv:
- Hom- txheej txheem tsim khoom (E/S/F)
- Qib- Chemistry thiab lub zog qib (A/B)
- NPS- nominal yeeb nkab loj, tsis yog qhov tseeb sab nraud txoj kab uas hla
- Teem caij- phab ntsa thickness designation
- Ua kom tiav- dub ( zeb tiav) lossis galvanized
Kev tso tseg ib qho ntawm cov teb no yog ib qho ua rau muaj kev tsis sib haum xeeb. Daim ntawv tshaj tawm kev xeem zeb uas sau "A53 Gr. B" uas tsis muaj hom tseem ua tau raws li tsab ntawv ntawm PO tsis meej, tab sis nws yuav tsis ua raws li qhov tseeb engineering yog xav tias cov yeeb nkab seamless.
Kev xeem thiab ntawv pov thawj ua rau hauv tus qauv
A53 xav kom txhua qhov ntev ntawm cov yeeb nkab kom dhau ib qho ntawm ob qhov kev ntsuas siab tau txais - hydrostatic los yog kev ntsuas hluav taws xob tsis zoo - nrog rau txoj kev siv tau teev nyob rau hauv daim ntawv pov thawj zeb. Qib B kuj tso cai (tab sis Qib A tsis tas yuav nqa) cov kev xav tau ntxiv thaum tau teev tseg, xws li kev ntsuas cuam tshuam rau qis- kev pabcuam kub. Daim ntawv pov thawj zeb ua raws li A53 yuav tsum qhia: tus naj npawb cua sov, tshuaj ntsuam xyuas, tensile/yield tau, txoj kev xeem siv, thiab hom/qib/loj cov cim traceable rau lub cev yeeb nkab cim.
Qhov twg tsis meej pem feem ntau tshwm sim hauv kev xyaum
Ib tus neeg cog lus hauv cheeb tsam ib zaug tau txais kev xa khoom ntawm "A53 Qib B" cov yeeb nkab rau compressed - cov kab xa tawm cua thiab tsis lees txais nws ntawm daim ntawv txais vim hais tias sab nraud txoj kab uas hla tsis phim cov yeeb nkab isometrics. Daim ntawv pov thawj zeb yog chemically thiab mechanically raws li - tab sis qhov kev txiav txim tau muab tso rau ntawm NPS loj xwb, tsis tau lees paub lub sij hawm, thiab tus neeg muag khoom tau defaulted rau Schedule 40 thaum lub drawings hu rau Schedule 80. Tsis muaj dab tsi ntawm daim ntawv pov thawj yog tsis ncaj ncees lawm; qhov kev txiav txim yuav tsuas tsis tau teev txaus ntawm txoj hlua xaiv los tiv thaiv qhov kev xav.
FAQ
Q: Puas yog daim ntawv qib siab ib txwm txhais tau tias cov yeeb nkab zoo dua?
A: Tsis yog - Qib A thiab Qib B tsuas yog ob qho kev sib txawv ntawm chemistry / lub zog sib xyaw ua ke hauv A53, tsis yog qib zoo. Qib A cov ntsiab lus qis dua ua rau nws txias me ntsis zoo dua - khoov thiab vuam yam ntxwv, thaum Qib B lub zog siab dua tso cai rau cov phab ntsa nyias nyias ntawm tib qhov kev ntsuas siab. Qhov qhab nia raug yog ib qho uas phim tus qauv tsim, tsis yog ib qho nrog tsab ntawv "zoo dua".
Q: Hom E thiab Hom S yeeb nkab puas tuaj yeem siv sib hloov?
A: Rau feem ntau siab -piping daim ntaub ntawv uas ob qho tib si ua tau raws li tib yam chemistry thiab mechanical xav tau, yog - A53 kho lawv zoo ib yam rau cov hom phiaj tsim. Qee qhov tshwj xeeb lossis cov neeg siv kawg tseem xav tau seamless (Hom S) tshwj xeeb rau qee qhov kev pabcuam, yog li daim ntawv qhia tshwj xeeb yuav tsum tau kuaj xyuas ua ntej hloov ib qho rau lwm tus.
Q: Puas yog A53 yeeb nkab tuaj yeem tsim nyog rau kev siv cov qauv?
A: Tsis yog tsis muaj kev kuaj xyuas tus qauv. A53 qhov tsawg kawg nkaus tawm lub zog yog qis dua ASTM A500's rau puag ncig lub raj ntawm tib lub npe loj, yog li tsim raws li A500 lub rooj muaj peev xwm tsis tuaj yeem xav tias A53 yeeb nkab yuav ua tau zoo ib yam.
Q: "dub" txhais li cas ntawm daim ntawv pov thawj A53 zeb?
A: Dub yog hais txog qhov tsis muaj coated, raws li -tsim zeb tiav - nws tsis yog qib lossis qhov tsis xws luag, tsuas yog qhov tsis muaj galvanizing. Dub A53 yeeb nkab tseem yog tib yam chemistry, txhua yam, thiab kev xeem ntawv pov thawj raws li galvanized A53 ntawm tib hom thiab qib.
