Chithunzi cha ASTM A53
Mipope yachitsulo yopanda msoko ndi yowotcherera kuchokera ku DN 6 mpaka 650 mm yokhala ndi makulidwe a khoma malinga ndi ASTM A53 Matebulo X2.2 ndi X2.3, komanso mapaipi achitsulo.
Mtundu wa ASTM A53 ndi Gulu
Mtundu wa Chitoliro
Mtundu F:
Chitoliro Chotenthetsera Matako - Chitoliro chowotcherera mosalekeza.Amapanga angapo utali wa chitoliro, amene kenako kudula mu utali munthu ndi welded ndi makina kuthamanga opangidwa ndi otentha masikono.
Zindikirani: Mtundu F supezeka ndi ma flanges
Mtundu E:
kukana-welded chitoliro.Kulumikizana kwa matako aatali muutali umodzi, kapena mochulukira utali kuchokera pachombo chophwanyika, kenako kumadulidwa muutali wamunthu, kukhala ndi gawo lotalikirapo la matako, momwe kuphatikizako kumapangidwa ndi kutentha komwe kumachokera kukana kwapano muderali. chomwe chitolirocho chili, ndi kugwiritsa ntchito mphamvu.
Zindikirani: Mtundu E umaperekedwa osawonjezedwa kapena kuzizira mokulitsidwa mwa kusankha kwa wopanga.
Mtundu S:
Mipope Yopanda Msokonezo - Zophatikiza Zitoliro Zopanda Weld Zimapangidwa kuchokera kuzitsulo zotentha, ngati kuli kofunikira, ndikuzizira kozizira kwa chinthu chotentha chopangidwa ndi tubular kuti apange mawonekedwe ofunikira, kukula kwake, ndi katundu.
Gulu la Gulu
Gulu A:
Iyi ndiye giredi yoyambira ndipo ndiyoyenera kusamutsa madzimadzi otsika komanso magwiritsidwe ena ampangidwe.
Gulu A limakondedwa ngati mapaipi akufunika kuti aphimbidwe mwamphamvu kapena kupindika mozizira.
Gulu B:
Ichi ndi giredi yamphamvu yolimba komanso yokana kukanikiza kuposa Giredi A ndipo nthawi zambiri imagwiritsidwa ntchito pazopanikizika kwambiri.
Kumaliza kwa ASTM A53
Lathyathyathya End: mawonekedwe wamba mapeto a chitoliro si kukonzedwa, ntchito pakufunika zina processing wa zinthu.
Ulusi Mapeto: Mapeto a chitoliro amakonzedwa ndi ulusi kuti athandizire kulumikizana kwa chitoliro.
Beveled End: Mapeto a chitoliro ndi beveled, ndipo makamaka ntchito kugwirizana kuwotcherera.
Zida za ASTM A53
Chitsulo cha mapaipi opanda msoko ndi owotcherera ayenera kupangidwa ndi chimodzi kapena zingapo mwa izi:
Ng'anjo Yotsegula, Ng'anjo Yamagetsi, kapena Alkaline Oxygen.
Kutentha Chithandizo
Ma welds mu Gulu B Mtundu E kapena Type F chitoliro azitenthedwa pambuyo powotcherera mpaka 1000 F [540°C] kuti pasakhale martensite wosatentha.

Mechanical Properties
Kuyesera kwina kwa ASTM A53
Bend Test
DN 50 (NPS 2) kapena zing'onozing'ono: kutalika kokwanira kwa chitoliro kudzakhala wokhoza kuzizira kupyola 90 ° kuzungulira cylindrical mandrel, m'mimba mwake ndi nthawi khumi ndi ziwiri zomwe zimatchulidwa kunja kwa chitoliro, popanda kupanga ming'alu pa gawo lililonse komanso popanda kutsegula. weld.
Tsekani kupopera: chitolirocho chidzayima kukhala chozizira mpaka 180°kuzungulira cylindrical mandrel, m'mimba mwake ndi kasanu ndi katatu kamene kafotokozedwe kunja kwa chitoliro, popanda kulephera.
Chitoliro chowonjezera kawiri pa DN 32 (NPS 11/4):osafunikira kuyesedwa kwa bend.
Mayeso a Flattening
Chitoliro chowotcherera pamwamba pa DN 50 mm mu kulemera kwamphamvu kwambiri kapena kupepuka: kudzakhala kuyesa kosalala.
Chitoliro Chopanda Msoko: Palibe kuyesa.
Kuyesedwa kwa Hydrostatic
Chitoliro Chopanda Mapeto: Kupanikizika koyenera malinga ndi Table X2.2.
Chitoliro Chophatikizika ndi Chophatikizana: Kupanikizika koyenera malinga ndi Table X2.3.
Nondestructive Electric Test
Ngati mayeso amagetsi osawononga apangidwa, kutalika kwake kumalembedwa ndi zilembo "NDE".
Zokhala ndi malata
Chitoliro champhamvu cha ASTM A53 chidzakometsedwa mkati ndi kunja ndi njira yotentha yoviika.
Zinc yomwe imagwiritsidwa ntchito popaka idzakhala giredi iliyonse ya zinc yogwirizana ndi Specification B6.Chitoliro cha malata chizikhala chopanda madera osakutidwa, matuza, ma depositi otuluka, ndi kuphatikizika kwa zinyalala.Ziphuphu, mawonedwe, ma globules, kapena ma depositi olemera a zinc omwe angasokoneze kagwiritsidwe ntchito ka zinthuzo sizidzaloledwa.
Pamwamba pa chitoliro chachitsulo chizikhala ndi zokutira zinki zosachepera 0,40 kg/m² powerengera kulemera ndi dera la zokutira zamakasi.
