ASTM A106 Chikamu
Pipe type: seamless simbi pombi.
Nominal Pipe Size: Inovhara isina musono pombi yesimbi kubva kuDN6-DN1200 (NPS1/8-NPS48).
Ukobvu hwemadziro: Ukobvu hwemadziro hunodiwa kuti usangane nezvinodiwa zveTafura 1 yeASME B36.10M.
ASTM A106 Giredhi
ASTM A106 ine mamakisi matatu epombi yesimbi: Giredhi A,Giredhi B, uye Grade C.
Musiyano mukuru pakati pemagiredhi matatu ndeye makemikari anoumbwa uye mechanical properties.
ASTM A106 Raw Materials
Simbi inofanira kuurawa simbi.
Simbi inogadzirwa uchishandisa yekutanga kunyunguduka, inogona kunge yakavhurika-yevhu, basic-okisijeni, kana yemagetsi-choto, pamwe yakasanganiswa neyakasiyana degassing kana kunatsa.
ASTM A106 Seamless Simbi Pipe Generation Method
Seamless simbi pombiinogadzirwa nenzira mbiri: inotonhora-inodhonzwa uye inopisa-yakapera.
DN ≤ 40mm simbi isina musono pombi inogona kutonhora-inodhonzwa kana kupisa-kupedzwa.
DN ≥ 50mm isina musono simbi pombi inopisa-yapera.
Hot Treatment
Kupisa-kupedzwa ASTM A106 isina musono simbi pombi haidi kurapwa kupisa.
Cold-drawn ASTM A106 machubhu esimbi asina musono anoda kupiswa nekupisa patembiricha ≥ 650°C.
Kuumbwa Kwemakemikari
ASTM A106 Giredhi A, Giredhi B, uye Giredhi C mukuumbwa kwemakemikari yemusiyano mukuru ndiwo mutsauko uripo pakati pezviri muC neMn, zviri mukati mezvimwe zvinhu mumagiredhi akasiyana zvinogona kuve nemusiyano mudiki, asi kazhinji kudzora a zvishoma zvishoma.
Mechanical Properties
Hurefu hwakareba mu2 in. (50 mm) huchatemwa neinotevera equation:
inch-pound units:
e=625,000A0.2/UO.9
Sl zvikamu:
e=1940A0.2/U0.9
e: elongation shoma mu2 in. (50 mm), %, yakatenderedzwa kusvika padyo 0.5%
A: muchinjika-chikamu nharaunda yeiyo tension test specimen, in2(mm2） zvichibva pane yakatsanangurwa kunze kwedhayamita kana zita remuenzaniso hupamhi uye yakatsanangurwa madziro ukobvu,yakatenderedzwa kusvika padyo 0.01 mukati2(1 mm2).
Kana iyo nzvimbo yakaverengerwa yakaenzana kana yakakura kupfuura 0.75 mukati2(500 mm2), ipapo kukosha 0.75 mukati2(500 mm2) ichashandiswa.

Test Program
ASTM A106 ine yakadzama zvirevo zvekuumbwa kwemakemikari, ongororo yekupisa, zvinodiwa zvemuchina, kukotama zvinodiwa, bvunzo dzekubata kumeso, hydrostatic bvunzo, uye isingaparadzi yemagetsi kuyedzwa.
Kemikari Inoumbwa / Heat Analysis
Heat Ongororo inzira inoshandiswa kuona zviri mukati mechimwe nechimwe chemakemikari zvinhu musimbi kuona kuti kemikari yeimwe neimwe yakawanda yezvinhu inosangana nezvinodiwa zveASTM A106.
Kutsunga kwemakemikari kunobva pakuongorora kwekushisa.Chinonyanya kutariswa chiri pane zviri mukati meiyo zvinhu kabhoni, manganese, phosphorus, sarufa, uye silicon, iyo miyero ine mhedzisiro yakananga pane zvinhu zvepombi.
Tensile Zvinodiwa
Machubhu anofanirwa kusangana nekusimba kwakasimba, simba regoho, uye elongation zvinodiwa.Izvi zvinovimbisa kusimba uye kusimba kwechubhu pane tembiricha dzakakwirira.
Kupeta Zvinodiwa
Kubhenda bvunzo dzinoshandiswa kuongorora kuomarara uye deformation yepurasitiki yemachubhu kana ichiiswa pasi pekupeta kushushikana kuitira kuti ive nechokwadi chekuvimbika kwechubhu panguva yekuisa nekushandiswa.
Flattening Miedzo
Flattening Miedzo inoshandiswa kuongorora iyo ductility uye kuramba kuputika kwemachubhu esimbi.Muedzo uyu unoda kuti pombi igadzirwe kune imwe dhigirii pasina kutsemuka kuratidza kunaka kwezvinhu uye kukwana kweiyo tekinoroji yekugadzirisa.
Hydrostatic Test
Kuyedzwa kweHydrostatic inhanho yakakosha mukutarisa kudzvanywa-kutakura simba repombi yesimbi nekuisa kudzvanywa kwakakwira kupfuura iyo inodiwa nechiyero kuti ive nechokwadi chechimiro chayo uye kusavapo kwekudonha.
Nondestructive Electric Test
Nondestructive Electric Test (eg ultrasonic test or electromagnetic test) inoshandiswa kuona zvakakanganisika mukati uye pamusoro senge makatsemuka, inclusions, kana maburi mumachubhu esimbi kuona kunaka kwechigadzirwa.
Dimensional Tolerances
Misa
Hukuru chaihwo hwepombi hunofanira kunge huri muhupamhi hwe97.5% - 110%yehuwandu hwakatarwa.
Mapombi muNPS 4 [DN 100] uye madiki anogona kuyerwa mumijenya iri nyore;
Mapombi akakura kupfuura NPS 4 [DN 100] achayerwa akaparadzana.
Outer Diameter
Kune OD> 250 mm (10 mu) machubhu, kana yakakwirira OD yakarurama ichidiwa, inobvumirwa OD kusiyana ndeye ± 1%.
Kune ID> 250 mm (10 mu) machubhu, kana yakakwira ID yechokwadi ichidikanwa, iyo inotenderwa ID musiyano ndeye ± 1%.
Ukobvu
Minimum madziro ukobvu = 87.5% yeakatsanangurwa madziro ukobvu.
Urefu
Single random urefu: 4.8-6.7 m [16-22ft].5% yehurefu inobvumirwa kuva isingasviki 4.8 m [16 ft], asi kwete kupfupika kupfuura 3.7 m [12 ft].
Hurefu hwakapetwa kaviri: Hurefu hwepakati peavhareji i10.7 m [35 ft] uye hurefu hudiki ndeye 6.7 m [22 ft].Zvishanu kubva muzana zvehurefu zvinotenderwa kuva pasi pe6.7 m [22 ft], asi kwete kupfupika kupfuura 4.8 m [16 ft].
Kurapa Kwekukanganisa Kwepamusoro
Kusarudza Kukanganisa
Kana kukanganiswa kwepamusoro kuchiitika mumachubhu anopfuura 12.5% yezita remadziro ukobvu kana kudarika hushoma hwemadziro ukobvu, hurema hunofanirwa kubviswa nekukuya chero yasara madziro ukobvu iri 87.5% kana kupfuura yeyakatsanangurwa ukobvu ukoshi.
Zvisingakuvadzi Zvikanganiso
Kuita kuti iyo yepamusoro kurapwa ienderane nezvinodiwa maitiro, zvinotevera zvisiri zvinokuvadza zvirema zvinofanirwa kubviswa nekukuya:
1. Mechanical marks uye mabrasions - senge macable marks, mazino, magirodhi, mavanga ekuumburuka, mabhora anokwenya, indentations nema mold marks, nemakomba, hapana kana chimwe chazvo chinodarika 1/16 mu (1.6mm) zvakadzama.
2. Kusakwana kwekuona, kunyanya macrusts, seams, laps, misodzi, kana zvimedu zvakadzika kupfuura 5 muzana yehukobvu hwezita.
Defect Repair
Kana mavanga kana zvikanganiso zvabviswa nekukuya, nzvimbo yakatsetseka yakakomberedzwa ichachengetedzwa uye ukobvu hwemadziro epombi haizove isingasviki 87.5% yehukoshi hwakatarwa.
Kugadzirisa welds kunoitwa zvinoenderana neASTM A530/A530M.
Tube Marking
Imwe neimwe ASTM A106 simbi pombi ichaiswa chiratidzo chemugadziri, yakatarwa giredhi, zviyero, uye Rongedza giredhi ruzivo rwekuzivikanwa uye kuteedzera.
