ASTM A214 tus qauv yog ib qho tshwj xeeb tshwj xeeb tsim rau hluav taws xob tiv thaiv welded carbon steel hlab. Nws qhia txog cov tshuaj muaj pes tsawg leeg, qhov ntev specifications, tolerances, thiab lwm yam txheej txheem rau cov hlab no, kom ntseeg tau tias lawv muaj cov neeg kho tshuab thiab thermal zog tsim nyog rau kev ua hauj lwm kub hloov. Cov qauv no tshwj xeeb yog tsim los siv rau hauv cov khoom siv hluav taws xob thiab cov condensers, tsim cov txheej txheem nruj heev los lav cov raj 'kev tsim nyog rau cov ntawv thov.
Qhov ntev ntawm ASTM A214 ERW Heat Exchanger Tube
- Txuj: ASTM A214 / ASME SA214
- Khoom siv: Carbon Steel
- Sab nraud txoj kab uas hla (OD): 6mm -76.2mm
- Phab ntsa Thickness (WT): 1mm -14mm
- Hom: Hluav taws xob tsis kam welded (ERW)
- Daim ntawv thov: Kub exchanger thiab condenser
ASTM A214 muab qhov tseem ceeb rau kev ua haujlwm ntawm cov vuam tsis kam (ERW) txheej txheem rau kev tsim cov raj no. ERW txoj kev siv cov zaus tam sim no los tsim cov welds, khav theeb lub voj voog luv luv. Nws yog qhov zoo rau kev tsim khoom loj thiab cov chaw tsim khoom loj, ua rau txo qis ntawm tag nrho cov nqi tsim khoom. Ib txhij, cov cuab yeej siv thiab kev ua haujlwm cuam tshuam ncaj qha, tshem tawm cov kev xav tau rau cov khoom siv tiv thaiv roj kim. Cov cua kub ceev thiab cua txias cov yam ntxwv ntawm cov vuam tsis kam, ua ke nrog nws qhov txwv tsis pub muaj cua sov, ua rau cov vuam deformation tsawg heev.Qhov no ua pov thawj los ua qhov zoo tshaj plaws rau cov ntawv thov uas xav tau qhov tseeb hauv vuam deformation.
Raws li ASTM A214 / ASME SA214 tus qauv, cov khoom siv raj yuav tsum ua raws li cov lus qhia hauv qab no hais txog tshuaj muaj pes tsawg leeg:

- Cov pa roj carbon monoxide yog qhov tseem ceeb hauv cov pa roj carbon steel, cuam tshuam cov khoom siv lub zog thiab hardness.
- Manganese feem ntau muab tso rau hauv cov pa roj carbon steel los txhim kho nws lub zog thiab toughness. Lub xub ntiag ntawm manganese ua rau cov khoom muaj peev xwm tiv taus kev ntxhov siab thiab deformation.
- Phosphorus feem ntau txwv rau qhov feem pua siab tshaj plaws los tiv thaiv cov embrittlement ntawm hlau. Kev tswj cov ntsiab lus phosphorus yog qhov tseem ceeb rau kev tswj hwm qhov xav tau sib npaug ntawm cov khoom siv kho tshuab.
- Sulfur yog lwm yam tswj hwm los tiv thaiv kev cuam tshuam ntawm cov hlau ductility thiab toughness. Cov ntsiab lus sulfur feem ntau yog nyob rau hauv cov qib siab tshaj plaws.
Ib cag los ntawm delineating cov tshuaj muaj pes tsawg leeg, ASTM A214 kuj qhia txog cov khoom siv ntawm cov hlau tsis kam-welded carbon steel hlab. Lub zog tensile, lub zog tawm los, thiab elongation yog qhov tseem ceeb tsis zoo rau kev ua kom lub raj muaj peev xwm tiv taus kev ua haujlwm thiab muaj kev ntseeg tau ruaj khov hauv kev siv hluav taws xob sib hloov.

- Lub zog tensile quantifies qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus thaum raug ncab lossis rub ua ntej mus txog qhov tseem ceeb ntawm kev sib cog lus hu ua necking.
- Yield zog qhia qhov kev ntxhov siab uas cov khoom pib ua cov yas deformation, cim qhov pib deformation mus tas li nyob rau hauv load.
- Elongation ntsuas qhov twg cov khoom tuaj yeem ncab lossis deform ua ntej ncav cuag qhov tawg. Txaus elongation yog qhov tseem ceeb rau kev tiv thaiv kev ntxhov siab thiab deformations thaum siv ua haujlwm.
- Hardness ua hauj lwm raws li ib tug metric rau cov khoom tsis kam mus deformation, tshwj xeeb tshaj yog nyob rau hauv teb rau indentation los yog khawb.
- Qhov chaw ntawm ASTM A214 ERW Heat Exchanger Tube
ASTM A214 / ASME SA214 tus qauv tswj kev tshem tawm cov nplai lossis oxides uas tuaj yeem tsim rau saum npoo ntawm cov hlab thaum lub sijhawm tsim khoom. Qhov no tau lees paub qhov chaw uas du thiab tsis muaj qhov tsis xws luag, tiv thaiv cov teeb meem xws li xeb thiab txhim kho cov cua sov kom zoo.
- Kev Kho Mob Kub Kub: Ntau dua lossis sib npaug rau 900 degree [1650℉]
