Wopanga Mapaipi Achitsulo Otsogola & Wopereka Ku China |

Kusiyana Pakati pa A671 ndi A672 EFW Mapaipi

ASTM A671 ndi A672 onse ndi miyeso yamachubu achitsulo opangidwa kuchokera ku mbale zopatsirana zamtundu wamagetsi ndi njira zowotcherera zamagetsi (EFW) ndikuwonjezera zitsulo zodzaza.

Ngakhale ali ofanana m'mbali zambiri, monga zofunikira zowotcherera, chithandizo cha kutentha, ndi kulekerera kwapakati, amasiyana malinga ndi momwe amagwiritsira ntchito, kalasi, kalasi, miyeso, ndi ntchito zenizeni.

Kuchuluka kwa Ntchito

Chithunzi cha ASTM A671:Matchulidwe Okhazikika a Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures

Chithunzi cha ASTM A672: Mafotokozedwe Okhazikika a Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperature

Size Range

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

Chithunzi cha ASTM A672: DN≥400mm[16 mu] ndi WT≤75mm[3 mu].

Kuyerekeza kwa M'kalasi

Machubu amagawidwa molingana ndi mtundu wa chithandizo cha kutentha chomwe amalandira panthawi yopangira komanso ngati akuwunikiridwa ndi radiographical ndikuyesedwa kukakamizidwa.

ASTM A671 ili ndi mitundu yambiri yamagulu kuposa ASTM A672, kuwonetsa njira ya A671 yogawa zinthu za brittleness ndi zolephera zomwe zimatha kuchitika m'malo otentha kwambiri.
Izi ndichifukwa choti mulingo wa A671 umapereka tsatanetsatane wazinthu zotsika kutentha zomwe zimapangidwira kuti chitolirocho chipitirire kuchita bwino m'malo ozizira.Mosiyana ndi izi, ASTM A672 imayang'ana kwambiri kuzolowera zovuta zosiyanasiyana komanso kutentha kwapakati, zomwe zimaphatikizapo kuyang'anizana ndi kuwongolera mitundu yosiyanasiyana ya kupsinjika.

Kuyerekeza kwa Maphunziro

Amasankhidwa molingana ndi mtundu wa mbale yomwe imagwiritsidwa ntchito popanga machubu achitsulo.

Magulu osiyanasiyana amayimira mitundu yosiyanasiyana yamankhwala komanso makina amakina osiyanasiyana azovuta komanso kutentha.

Magiredi osiyanasiyana angakhudze mtengo ndi magwiridwe antchito a polojekiti.
Kugwiritsa ntchito chitoliro chachitsulo chapamwamba nthawi zambiri kumatanthawuza ndalama zambiri zakuthupi, koma kusankha zinthu moyenera kungachepetse ndalama zolipirira ndikuwonjezera moyo wautumiki pakapita nthawi.

Enieni Mapulogalamu

Mapulogalamu a ASTM A671 Steel Tubing

Ntchito za Cryogenic: monga kachitidwe ka gasi wachilengedwe (LNG) ndi kayendetsedwe ka kayendetsedwe kake, amafuna machubu omwe amatha kusunga makina abwino pamatenthedwe otsika kwambiri.

Njira zoperekera gasi mumzinda: M'makinawa, mapaipi angafunikire kugwira ntchito pa kutentha kochepa kwachisanu, kotero kuti mapepala enieni a chitoliro chachitsulo amafunikira kuti atsimikizire chitetezo ndi mphamvu.

Chemical processing malo: M'makina opangira mankhwala ndi kuzizira, madzi ena amayendetsedwa pa kutentha kwambiri, zomwe zimafuna kugwiritsa ntchito chitoliro cha ASTM A671 kuti chiteteze kuphulika kwa chitoliro chifukwa cha brittleness pa kutentha kochepa.

Mapulatifomu aku Offshore ndi malo opangira mafuta: Malowa nthawi zambiri amakhala m'madzi ozizira, ndipo kugwiritsa ntchito chitoliro cha A671 kumatsimikizira kudalirika komanso kulimba m'malo ozizira am'madzi.

Mapulogalamu a ASTM A672 Steel Tubing

Zomera zamagetsi: Makamaka mu makina opangira boiler ndi nthunzi, machitidwewa amafunikira mapaipi omwe amalimbana ndi kutentha kwakukulu ndi kupanikizika kuti asamutse bwino nthunzi ndi madzi otentha.

Oyeretsa: Pakuyenga, mapaipi amafunikira kuti asamutse bwino mafuta osakanizika ndi zinthu pakati pa malo opangira zinthu zosiyanasiyana, ndipo mapaipiwa ayenera kupirira kutentha kwambiri komanso kuukira kwamankhwala.

Mizere Yotengera Kuthamanga Kwambiri: Mizere yopatsirana yothamanga kwambiri imagwiritsidwa ntchito kunyamula madzi othamanga kwambiri kapena mpweya monga gasi wachilengedwe ndi mafuta.

Industrial Pressure Systems: Pakupanga ndi ntchito zina zamafakitale, machitidwe ambiri okakamiza amafunikira mapaipi odalirika kwambiri kuti atsimikizire chitetezo ndi magwiridwe antchito.

Posiyanitsa pakati pa zinthuzi ndi ntchito, zikuwonekeratu kuti ngakhale miyezo ya ASTM A671 ndi A672 imadutsana muzinthu zina zaukadaulo, imagwira ntchito zosiyanasiyana malinga ndi zofunikira za chilengedwe ndi magwiridwe antchito.
