ASME SA53 Qib B ERW Yeeb Nkab

ASME SA53 Qib B ERW yeeb nkabyog welded carbon steel tubing ua los ntawm cov txheej txheem hluav taws xob tsis kam vuam (ERW) thiab muab rau ASME SA53 / ASTM A53 specification. Hauv SA53, Qib B qhia txog qib siab dua - lub zog (tsawg kawg tensile 415 MPa / 60 ksi, tawm los 240 MPa / 35 ksi). Tib qib yog ua nyob rau hauv ob hom:Hom S(seamless) thiabHom E(hluav taws xob-tsis kam welded). Nplooj ntawv no npogHom E (ERW), uas yog tsim los ntawm steel skelp, welded raws ib tug ncaj seam, thiab ces loj, kuaj, thiab xaiv kub -dip galvanized.

Qib B ERW yog ib qho ntawm cov pa roj carbon steel kav ntau tshaj plaws rau qis - mus rau nruab nrab - cov tshuab siab. Nws welds, khoov, thiab threads yooj yim, thiab yog stocked nyob rau hauv dub (liab qab) thiab zinc-coated versions rau sab hauv tsev thiab sab nraum zoov dej.

 

Scope thiab Standard

ASME SA53 yog lub boiler - thiab - siab - nkoj - code tsab ntawmASTM A53 / A53M - Txheem Specification rau Yeeb Nkab, Hlau, Dub thiab Kub-Dipped, Zinc-Coated, Welded thiab Seamless. Cov kev qhia tshwj xeeb suav nrog cov yeeb nkab loj uas tsim los rau kev siv tshuab thiab kev siv siab thiab siv rau hauv cov pa, dej, roj, thiab cov kab cua.

SA53 yog muab rau peb hom thiab ob qib:

Hom S - Seamless(kub-ua tiav lossis txias- kos); Qib A thiab B.

Hom E- Hluav taws xob- tsis kam welded (ERW); Qib A thiab B.Qhov no yog daim ntawv uas muaj nyob rau ntawm nplooj ntawv no.

Hom F- Rauv- taub qab welded (nruam weld);Qib A nkaus xwb(tsis muaj nyob rau qib B).

SA53 Qib B feem ntau yog dual- ntawv pov thawj nrog ASTM A106 Qib B seamless yeeb nkab, tab sis ob qho yog cov khoom sib txawv. Nplooj ntawv no tsuas yog siv daim ntawv welded (Hom E).

Daim ntawv thov

SA53 Qib B ERW yeeb nkab yog siv qhov nruab nrab lub zog thiab zoo weldability teeb meem ntau dua li siab - lub zog xa mus rau lub luag haujlwm:

Siab piping:qis- mus rau nruab nrab- cov kab hluav taws xob siab, cov tshuab cua compressed, cov kab hydraulic, dej thiab roj faib.

Kev tiv thaiv hluav taws:hluav taws sprinkler systems.

HVAC thiab kav dej:chilled - dej thiab kub - cov kab dej, cov kav dej hauv tsev.

Qauv:handrails, guardrails, kev txhawb nqa, scaffolding, fencing.

Kev pabcuam dav dav:conduit, tsis yog - cov txheej txheem tseem ceeb piping.

SA53 yogtsis yogib qhov ntev -kab kis kab yeeb nkab (siv API 5L rau cov kav dej), yogtsis yognpaj rau kev pab cuam cryogenic, thiab rau siab siv qhov tso cai kub raws li cov cai (feem ntau txog li 425℃/ 800℃F).

 

Cov txheej txheem tsim khoom (ERW, Hom E)

Skelp / coil npaj- steel strip yog ntug-milled thiab ntxuav.

tsim- lub cev pob txha yog dov rau hauv ib puag ncig.

Vuam- cov npoo yog koom nrog hluav taws xob tsis kam (feem ntau siab - zaus induction, HFI / ERW) tsis muaj cov hlau muab tub lim, tsim ib txoj kab ncaj nraim.

Sizing thiab straightening- lub raj yog me me rau nominal txoj kab uas hla thiab straightened.

Weld txias txias- xaiv kev kho cua sov ntawm thaj chaw weld lossis tag nrho - lub cev normalizing, ib qho kev txiav txim.

Hydrostatic xeem- txhua qhov ntev yog siab- kuaj.

Ua tiav- muab dub (liab liab) los yog kub-dip galvanized; xaus txiav tiaj, threaded, beveled, los yog grooved.

 

Vuam thiab Fabrication

Qib B ERW yeeb nkab haum rau vuam los ntawm SMAW, GMAW, thiab GTAW, thiab rau kev ua haujlwm xws li coiling, dabtsi yog khoov, thiab flanging. Hom E yeeb nkab tej zaum yuav yog rooj tog tsis nthuav dav lossis txias - nthuav dav ntawm qhov chaw tsim khoom xaiv. Thaum yuav tsum tau kaw coiling lossis txias dabtsi yog khoov, Qib A yog qhov zoo dua, tab sis qhov txias txias ntawm Qib B tau tso cai.

FAQ

Qhov txawv ntawm SA53 Qib B Hom E thiab Hom S yog dab tsi?

Ob leeg yog Qib B carbon steel nyob rau hauv ASME SA53, tab sis Hom E yog hluav taws xob -tsis kam welded (ERW) los ntawm steel skelp, thaum Hom S yog seamless (kub- tiav lossis txias- kos). Hom E yog daim ntawv uas muaj nyob rau ntawm nplooj ntawv no.

 

Puas yog ASME SA53 Qib B ERW tib yam li ASTM A53 Qib B ERW?

Yog lawm. ASME SA53 yog lub boiler - thiab - siab - nkoj - code tsab ntawm ASTM A53. Cov khoom xav tau, chemistry, thiab cov khoom zoo ib yam; Kev xaiv ASME yog siv thaum cov yeeb nkab raug txiav txim rau ASME BPVC lossis ASME B31 piping services.

 

SA53 Qib B ERW cov yeeb nkab puas tuaj yeem siv los ua cov kav dej rau cov roj thiab cov pa xa mus?

Tsis yog. SA53 yog ib qho dav dav - lub hom phiaj siab thiab kev pabcuam cov yeeb nkab, tsis yog qhov ntev - kis kab mob. Kev pabcuam txuas txuas ntxiv yuav tsum siv API 5L yeeb nkab. SA53 Qib B ERW yog tsim los rau cov kav dej siab, chav dej, dej, roj, thiab cua kab, thiab siv cov qauv siv.

 

Dab tsi yog SA53 Qib B ERW yeeb nkab nqa tau?

Tsis muaj ib qho kev ntsuas siab. Kev ua haujlwm siab nyob ntawm lub sijhawm ua yeeb nkab (phab ntsa thickness), txoj kab uas hla, qhov kub thiab txias, thiab cov cai tswj hwm (xws li ASME B31.1). Nws yuav tsum raug xam raws tus qauv tsim qauv, tsis yog nyeem los ntawm qib ib leeg.

 

Puas yog SA53 Qib B ERW yeeb nkab muaj galvanized?

Yog lawm. SA53 npog ob qho tib si dub (liab liab) thiab kub -dipped zinc-coated (galvanized) yeeb nkab. ERW Qib B tuaj yeem muab tau rau hauv ob qho xwm txheej; galvanizing yog siv tom qab vuam thiab hydrostatic kuaj.

 

Qhov kev pabcuam siab tshaj plaws rau SA53 Qib B ERW yeeb nkab yog dab tsi?

Rau kev pabcuam siab, qhov ntsuas kub tau tso cai ua raws li cov cai (xws li ASME B31.1) thiab feem ntau txog li 425℃(800℃F). Nws tsis yog npaj rau kev pabcuam cryogenic lossis rau kev ua haujlwm siab -kub/siab xa mus ua haujlwm.
