Musiyano Pakati peA671 neA672 EFW Mapaipi

ASTM A671 uye A672 ese ari maviri mazinga esimbi tubing akagadzirwa kubva mukumanikidza mudziyo-mhando mahwendefa nemagetsi fusion welding (EFW) matekiniki pamwe nekuwedzera kwesimbi dzekuzadza.

Kunyangwe iwo akafanana muzvinhu zvakawanda, senge zvinodikanwa zvewelding, kupisa kupisa, uye dimensional tolerances, anosiyana muhukuru hwemashandisirwo, giredhi, kirasi, zviyero, uye mashandisirwo chaiwo.

Chikamu cheApplication

ASTM A671: Yakajairwa Kutsanangurwa kweMagetsi-Fusion-Welded Simbi Pipe yeAtmospheric uye Yakaderera Tembiricha

ASTM A672: Yakajairwa Kutsanangurwa kweMagetsi-Fusion-Welded Steel Pipe yeHigh-Pressure Service paKupisa Kwepakati

Size Range

ASTM A671: DN≥ 400 mm [16 mu] uye WT ≥ 6 mm [1/4].

ASTM A672: DN≥400mm[16 mu] uye WT≤75mm[3 mukati].

Kuenzanisa Kwekirasi

Iwo machubhu akaiswa mumapoka zvichienderana nerudzi rwekurapa kwekupisa kwaanogamuchira panguva yekugadzira uye kuti kana kwete iwo akaongororwa radiographical uye kudzvanywa kwakaedzwa.

astm a671 yakasiyana nea672: kirasi

ASTM A671 ine huwandu hwakakura hwemhando kupfuura ASTM A672, inoratidza A671 yakawedzera nuanced maitiro ekuisa mumapoka zvinhu zvebrittleness uye kutadza modes zvinogona kuitika munzvimbo dzakadzika-tembiricha.
Izvi zvinodaro nekuti iyo A671 yakajairwa inopa yakadzama kuparara kweyakadzika-tembiricha zvivakwa zvakagadzirirwa kuve nechokwadi chekuti pombi icharamba ichiita zvakanaka mumamiriro ekutonhora.Kusiyana neizvi, ASTM A672 inotarisa kuchinjika kune dzakasiyana siyana uye ine mwero tembiricha mamiriro, ayo anosanganisira kutarisana uye kutonga akasiyana marudzi ekushushikana.

Giredhi Kuenzanisa

Yakakamurwa zvichienderana nerudzi rwendiro inoshandiswa kugadzira machubhu esimbi.

Magiredhi akasiyana anomiririra akasiyana maumbirwo emakemikari uye ma mechanical zvimiro zvekumanikidza kwakasiyana uye tembiricha mamiriro.

Magiredhi akasiyana anogona kukanganisa mutengo uye kuita kweprojekiti.
Kushandisa giredhi yepamusoro yepombi yesimbi kunowanzoreva kudhura kwezvinhu, asi kusarudzwa kwezvinhu zvakakodzera kunogona kuderedza mari yekugadzirisa uye kuwedzera hupenyu hwebasa munguva refu.

Specific Applications

Zvikumbiro zveASTM A671 Steel Tubing

Cryogenic services: senge liquefied natural gas (LNG) mabatiro uye masisitimu ekufambisa, anoda machubhu anokwanisa kuchengetedza yakanaka mechanical zvivakwa pakudzika kwakanyanya ambient tembiricha.

Guta gasi rekupa masisitimu: Mune aya masisitimu, mapaipi angangoda kushanda pakudziya kwakadzika kwechando, saka mamakisi chaiwo epombi yesimbi anodiwa kuti ave nechokwadi chekuchengetedza uye kushanda zvakanaka.

Zvigadzirwa zvekugadzira makemikari: Mumakemikari ekugadzirisa uye kutonhora masisitimu, mamwe madhiri anobatwa pane yakaderera tembiricha, inoda kushandiswa kweASTM A671 pombi kudzivirira kuputika kwepombi nekuda kwebrittleness pakudziya kwakaderera.

Offshore mapuratifomu uye zvivakwa zvekuchera mafuta: Izvi zvivakwa zvinowanzowanikwa mumvura inotonhora, uye kushandiswa kweA671 pombi kunovimbisa kuvimbika uye kusimba munzvimbo dzinotonhora dzemugungwa.

Zvikumbiro zveASTM A672 Steel Tubing

Simba zvinomera: Kunyanya mumabhoiler uye masisitimu emhepo, masisitimu aya anoda pombi inopokana nekupisa kwakanyanya uye kudzvanywa kwekufambisa kwakachengeteka kweutsi nemvura inopisa.

Refineries: Mukuita kwekunatsa, pombi inodiwa kuti ifambise zvakanaka mafuta asina kuchena uye zvigadzirwa pakati pezviteshi zvakasiyana zvekugadzira, uye mapaipi aya anofanirwa kumirisana nekupisa kwakanyanya uye kurwisa kwemakemikari maitiro.

High-Pressure Transmission Lines: High-pressure transmission mitsara inoshandiswa kutakura yakakwira-pressure fluid kana magasi akadai segasi rechisikigo neoiri.

Industrial Pressure Systems: Mukugadzira uye mamwe maindasitiri maapplication, akawanda ekumanikidza masisitimu anoda yakavimbika yakakwirira-kudzvanywa pombi kuti ive nechokwadi chekuchengetedza kugadzirwa uye kunyatsoita.

Nekusiyanisa pakati pezvivakwa izvi uye mashandisirwo, zvinova pachena kuti nepo ASTM A671 uye A672 pombi miyero inopindirana mune mamwe maitiro ehunyanzvi, inoshandira zvinangwa zvakasiyana zvichienderana nezvakatipoteredza uye zvekushanda zvinodiwa.
