ASTM A106 yog tus qauv Seamless Cov Yeeb Nkab Feem ntau tus tsim qauv qhia thaum cov kab yuav tsum nqa kua dej haus lossis roj. It is made for elevated-temperature service, is dimensioned in accordance with ASME B36.10M, and can be supplied with plain or beveled ends for welding, bending and flanging. Ntawm cov qhab nia A, B thiab C hauv AVEM A106, qib qhab, ductility thiab weldability thiab welminy heab, refinery beaders, txheej txheem piping, txheej txheem piping thiab fais fab nroj tsuag.
Cov Qauv thiab Xa Tawm
- Txheem: Astm A106 / ASME SA106
- Qib: B (Kuj tseem muaj A, C yog tias txoj haujlwm tso cai)
- Daim Ntawv: Seamless, Kub-} ua tiav lossis txias- ua tiav
- Xaus: Tiaj Kawg (PE) lossis beveled kawg (yuav tsum) rau vuam
- Qhov loj me: ASME B36.10M, NPS thiab sijhawm - raws li
Tshuaj Muaj Tshuaj
Cov qib yog ua raws li qhov yooj yim, zoo -} tswj cov pa roj carbon-manganese-silicon tsim. Kev tswj xyuas ntawm p thiab khaws cov yeeb nkab weldable thiab tawv.
| Teem nqi | C (%) | MN (%) | P (%) max | S (%) max | SI (%) min |
|---|---|---|---|---|---|
| A | Tsawg dua los yog sib npaug rau 0.25 | 0.27–0.93 | 0.035 | 0.035 | 0.10 |
| B | Tsawg dua los yog sib npaug rau 0.30 | 0.29–1.06 | 0.035 | 0.035 | 0.10 |
| C | Tsawg dua los yog sib npaug rau 0.35 | 0.29–1.06 | 0.035 | 0.035 | 0.10 |
Vim li cas qhov tseem ceeb: Cov pa roj carbon muab qib nws lub hauv paus muaj zog; Manganese pab tswj cov qauv ferrite-Pearlite thiab txhim kho kev nruj; Silicon txhim kho nplai / oxidation tsis kam thaum cov yeeb nkab nqa chav kub lossis cov xov xwm txheej txheem.
Cov Khoom Siv Neeg Kho Tshuab
Qib B yog "theem nrab" tab sis twb muaj zog txaus rau feem ntau cov ntawv thov cog.
| Teem nqi | Tensile lub zog (mpa) | Yield zog (mpa) | Elongation (%) |
|---|---|---|---|
| A | Ntau dua los yog sib npaug rau 330 | Ntau dua los yog sib npaug rau 205 | Ntau dua los yog sib npaug rau 20 |
| B | Ntau dua los yog sib npaug rau 415 | Ntau dua los yog sib npaug rau 240 | Ntau dua los yog sib npaug rau 20 |
| C | Ntau dua los yog sib npaug rau 485 | Ntau dua los yog sib npaug rau 275 | Ntau dua los yog sib npaug rau 20 |
Kev txhais lus rau kev tsim qauv thiab kev tsim qauv thiab cov ntaub ntawv: tensile zog tiv thaiv tiv thaiv burtsing thiab axial loads; paib lub zog yog qhov kev txwv ua ntej deformation tas mus li, tshwj xeeb tshaj yog rau high- siab khiav; Elongation ua kom cov yeeb nkab tuaj yeem yog ua teb - bent, welded thiab ntsia tsis muaj cracking.
Kev ua tau zoo hauv high - kev pab kub
A106 Qib B yog npaj nyob rau hauv kev pabcuam ntawm cov hlau kub ntxeem mus txog 400-450℃band. Nyob rau theem no cov ferrite-hlaws muaj ruaj khov, silicon pab ua kom cov nplaim hluav taws xob, thiab cov yeeb nkab ua rau nws lub siab} bearing muaj peev xwm. Tias yog vim li cas nws tau teev rau boiler pub kab, chav headers, cua sov {6} Cov roj kub roj hluav taws xob thiab cov tshuab hluav taws xob kub. Nrog rau kev tsim nyog pwht thiab cov txheej txheem vuam, cov yeeb nkab kuj tseem tuaj yeem khiav hauv kev pab tau hnoos qeev tsis muaj kev nruj.
Kev tsim khoom thiab kev kho cua sov
Rau A106 qib B Cov kev tsim khoom lag luam tsis yog qhov laj thawj txuas ntxiv - nws yog vim li cas cov yeeb nkab tuaj yeem ua haujlwm ntawm qhov kub thiab siab. Ib txoj kev sib raug zoo rau seamless A106 Qib B ntawm octal yeeb nkab zoo li no:
1. Kev xaiv lailet thiab chemicalstej
Cov khoom pib tsim ntau dua los ntawm kev tua (Full deoxidized), nplua} nplej} nplej great steel breatts uas twb tau raws li A106 tshuaj lom neeg. Qhov no ua kom pom tseeb p thiab s, huv huv thiab weldability. Cov cua sov raug tshawb xyuas ua ntej dov kom muaj cov phiaj xwm kho tshuab rau qib B tuaj yeem mus txog tom qab tsim thiab kho cua sov.
2. Cov cua sov Billet
Billets yog rhuab nyob rau hauv ib tug teb lossis taug kev {- barte rauv rau lub tho / dov txias. Cov cua kub sib xyaw yog qhov tseem ceeb ntawm no vim tias tsis sib luag yog qhov kub yuav ua rau phab ntsa- thickness kev hloov pauv thaum lub billet yog chob.
3. Kub Tho (Hollow ua)
Lub kub billet yog chob ntawm tus ntoo khaub lig - rob lossis mandrel tho zeb los ua lub plhaub khoob. Qhov no yog qhov twg cov yeeb nkab hloov los ntawm cov khoom khov kho mus rau hauv lub raj uas tsis muaj zog. Lub hom phiaj yog los tsim lub plhaub uas tsis muaj qhov faus nruab nrab thiab nrog txawm phab ntsa ib ncig ntawm txoj kev ncig.
4. Elongation thiab Plug / Mandrel Dov
Lub Plhaub Hollow yog tom qab ntawd elongated thiab dov hla ib lub mandrel lossis ntsaws zeb kom ncav cuag kom ze rau txoj kab uas hla thiab phab ntsa tuab. Ob peb lub yob sawv ntsug yuav raug siv los kho phab ntsa thiab txhim kho saum npoo. Cov kauj ruam no yog qhov tseem ceeb rau kev ua sab hauv du thiab rau kom khaws phab ntsa tuab tsis pub muaj siab ntev.
5. Sizing / Txo Zeb
Lub sizing lossis txo cov zeb coj cov yeeb nkab rau nws kawg od thiab roundness. Rau cov caij nyoog siab dua (tuab phab ntsa), yob cov tsis tau kho tau kho kom muaj kev saib xyuas zoo. Yog li sizing ntawm no txhais tau tias yooj yim vuam thiab zoo dua haum - mus rau ntawm qhov chaw.
6. Txias thiab Ncaj Ncees
Tom qab ua haujlwm kub, kav dej txias rau hauv txoj kev tswj hwm thiab tom qab ntawd dhau los ntawm lub tshuab ncaj. Txoj kab ncaj yog qhov tseem ceeb rau prefabricated spools thiab rau cov vuam tsis siv neeg.
7. Kev kho cua sov (raws li yuav tsum tau)
Ua raws li cov yeeb nkab loj, txo qhov sib xws thiab cov neeg yuav khoom tau txais, kav dej tuaj yeem yog qhov qub lossis ntxhov siab {}} relieved.
Li cas los hloov cov ferrite-petlite qauv, kev tshwm sim tawm ntawm qhov ntev thiab txhim kho kev nruj.
Kev ntxhov siab ntxhov siab tshem tawm cov kev ntxhov siab, uas yog qhov muaj txiaj ntsig yog tias cov yeeb nkab yuav muab welded rau hauv lub system uas yuav pom thermal cycling.
Qhov no tswj kev kho cua sov yog dab tsi pab A106 qib B kom nws qhov kev ua haujlwm kub thiab cuam tshuam hauv kev pabcuam kub.
8. Xov, NDE thiab Hydrotest
Cov kav dej tiav yog txiav kom ntev, xaus yog ntsib / BVELED, thiab txhua qhov ntev yog tshuaj xyuas visually rau sab thiab seem qhov tseeb. Tom qab ntawd cov yeeb nkab raug sim:
- hydrostatic kuaj kom muaj kev ntsuas cov khoom siab
- eddy - Tam sim no lossis ultrasonic nde saib rau sab hauv / saum toj tsis xws luag
- Cim thiab Txheej / Varnish rau Kev Tiv Thaiv
- Tsuas yog tom qab tag nrho cov kauj ruam no yog cov yeeb nkab tso nrog MTC.
Vim tias tag nrho txoj kev yog seamless (tsis muaj cov yeeb nkab weld), cov yeeb nkab muaj qhov laj thawj A106 yog xaiv Welded Yeeb Nkab rau high-}} kub kev pab.

Kuaj thiab tshuaj xyuas
Txhawm rau ua cov yeeb nkab uas tau txais rau cov siab thiab kub kev pab, ittm A106 yog hais txog cov kev xav tau dav dav hauv Astm A999. Cov yeeb nkab octal tuaj yeem muab tag nrho cov kev ntsuam xyuas:
- Hydrostatic qhov kev xeem ntawm txhua qhov ntev los ua pov thawj cov kev ntsuas siab
- Nondestructive Soj Ntsuam (EDDY tam sim no lossis ultrasonic) mus rau screen nto thiab sab hauv
- Tensile thiab hardness kev xeem rau ib qho kub ntawm steel los xyuas cov tshuab ua raws
- Flattening / bend kuaj rau ua kom pom kev
- Nrig, OD, Phab Ntsa thiab Ntev Daim tshev yuav kom ntseeg tau tias muaj kev ywj pheej
- MTCS rau 10204 3.1 / 3.2 rau tag nrho cov cua sov thiab sim traceability
