K41245 Seamless Steel Yeeb Nkab

1. Kev txiav txim siab cov khoom qib "K41245"

Qhov "K" ua ntej yog qhov tseem ceeb. Hauv Suav GB (Guobiao) cov qauv, uas muaj ntau heev hauv kev lag luam steel, "K" feem ntau qhia txog qib steel siv rau.pipeline tsheb thauj mus los rau cov kua.

Cia peb tawg nws ntxiv:

K: Qhia txog lub raj xa dej.

41: Zoo li hais txog qhovYam tsawg kawg nkaus Yield Strengthntawm cov khoom. Hauv qhov no, "41" tej zaum txhais tau tias 41,000 psi (Pounds per Square Inch). Thaum hloov mus rau chav ntsuas ntau dua, MegaPascals (MPa), qhov no yog kwv yees li283 MPa ua.

* Ceeb Toom: Qee zaum cov qhab nia raug xaiv los ntawm MPa ncaj qha (piv txwv li, L245, qhov twg 245 yog MPa), tab sis cov "K" series feem ntau siv psi - raws li tus lej.*

245: Tus lej no tuaj yeem hloov pauv me ntsis nrog rau "41". Nws yog qhov muaj feem ntau tias qhov "245" no sib haum rau cov metric yield zog nyob rau hauv MPa, uas yog ib tug ntau heev qib hu ua.L245los yogGB/T 9711 PSL1 L245. Lub "L" sawv cev rau "Line Pipe".

Cov ntsiab lus ntawm Qib:"K41245" yog yuav luag txhua tus suav GB tus qauv sib npaug rau cov thoob ntiaj teb cov kav dej steel qibAPI 5L Gr. Blos yogL245. Nws yog cov pa roj carbon steel nrog lub zog zoo thiab zoo heev weldability, tsim tshwj xeeb rau kev xa cov roj, roj, thiab lwm yam kua.

Cov khoom tseem ceeb ntawm K41245 / L245 / API 5L Gr. B:

Yam tsawg kawg nkaus Yield Strength:245 MPa (35,500 psi) lossis ~ 41,000 psi (nyob ntawm tus txheej txheem txhais lus).

Yam tsawg kawg Tensile Strength:415 MPa (60,200 psi).

Zoo ductility thiab cuam tshuam tsis kam.

2. Kev nkag siab "Seamless Steel Pipe"

Qhov no qhia tau hais tias cov yeeb nkab yog tsim li cas.

Seamless (SMLS):Cov yeeb nkab yog tsim los ntawm cov khoom cylindrical steel billet. Lub billet yog rhuab thiab ces pierced los ntawm qhov chaw nrog ib tug mandrel los tsim ib tug hollow raj tsis muaj seams los yog welds.

Qhov zoo:

Uniform Strength:Tsis muaj welded seam uas tuaj yeem yog qhov tsis muaj zog.

Zoo dua rau High Pressure:Withstands siab dua sab hauv thiab sab nraud.

Kev ntseeg tau:Txaus siab rau cov ntawv thov tseem ceeb hauv qhov chaw hnyav.

Qhov tsis zoo:

Feem ntau kim tshaj welded kav (xws li ERW lossis LSAW).

Cov phab ntsa tuab dua thiab hnyav dua.

Kev tsim khoom siv sijhawm ntev dua.

Common Specifications thiab Standards

A K41245 Seamless Steel Yeeb Nkab feem ntau yuav raug tsim nyob rau hauv ib qho ntawm cov hauv qab no Suav lossis thoob ntiaj teb cov qauv:

GB/T 9711: Petroleum thiab natural gas industries - Cov yeeb nkab steel rau kev thauj mus los hauv cov kav dej.Qhov no yog thawj Suav tus qauv rau cov raj xa dej thiab feem ntau sib npaug rau thoob ntiaj teb API 5L tus qauv.

API 5L: Specification rau Kab Yeeblos ntawm American Petroleum Institute. Qhov no yog qhov ntsuas thoob ntiaj teb.

GB/T 8163: Seamless steel raj rau kev thauj mus los.Qhov no yog tus qauv dav dav rau kev thauj cov kua dej, tsis yog rau cov kav dej thiab cov kav dej.

Daim ntawv teev cov khoom siv tag nrho yuav zoo li:Seamless Steel Yeeb Nkab GB / T 9711 PSL1 L245 (K41245).

Tej kev siv

Vim nws cov khoom sib npaug, K41245 Seamless Pipes tau dav siv hauv:

Onshore thiab Offshore Roj & Gas Pipelines:Rau kev sib sau cov kab, cov kab sib txuas, thiab cov kav dej hauv qab hiav txwv.

Natural Gas Transmission Networks:Cov kab tseem ceeb rau kev thauj cov nkev roj mus ntev.

Dej Txhaj Kab hauv Cov Roj Teb:Rau cov roj theem nrab rov qab.

Kev siv tus qauv:Thaum tsim los rau lub siab, nws kuj tseem siv tau rau hauv cov qauv txheej txheem uas nws lub zog thiab seamless xwm muaj txiaj ntsig zoo (xws li, siab -siab hydraulic systems, bearing tes tsho).

Chemical thiab Petrochemical Plants:Rau cov txheej txheem kab hauv cov nroj tsuag.

Cov ntsiab lus

Thaum muab cov khoom no, nws yog ib qho tseem ceeb kom qhia meej tus qauv (piv txwv li, GB / T 9711 lossis API 5L), qhov kev xa khoom, qhov ntev (OD & WT), thiab ib qho kev ntsuas ntxiv uas yuav tsum tau ua (xws li kev sim cuam tshuam lossis NDT) kom ntseeg tau tias nws ua tau raws li koj qhov kev xav tau.
