ASTM A192 (Chithunzi cha ASME SA192) Chitoliro chachitsulo ndi chitoliro chachitsulo chosasunthika chomwe chimagwiritsidwa ntchito potentha kwambiri komanso kutentha kwambiri ndipo chimagwiritsidwa ntchito kwambiri m'ma boilers ndi osinthanitsa kutentha.
M'mimba mwake: 1/2" - 7" (12.7 mm - 177.8 mm);
Makulidwe a khoma: 0.085 ″ - 1.000 ″ (2.2 mm - 25.4 mm);
Kukula kwina kwa chitoliro chachitsulo kungaperekedwenso ngati pakufunika, malinga ngati zofunikira zina zonse za A192 zikwaniritsidwa.
ASTM A192 imapangidwa pogwiritsa ntchito njira yopanda msoko ndipo imatha kutentha kapena kuzizira ngati pakufunika;
Komanso, chizindikiritso cha chitoliro chachitsulo chiyenera kuwonetsa ngati chitoliro chachitsulo chikuwotcha kapena chozizira.
Kumaliza kotentha: Amatanthauza njira yomaliza miyeso yomaliza ya chubu chachitsulo potentha.Pambuyo pa chubu chachitsulo chakhala chikugwira ntchito yotentha monga kugudubuza kotentha kapena kujambula kotentha, sikuzizira kwambiri.Machubu achitsulo otsirizidwa ndi otentha amakhala olimba komanso amadumphira koma amakhala ndi kulekerera kwakukulu.
Kuzizira kunatha: Chitoliro chachitsulo chimakonzedwa mpaka kufika pamiyeso yake yomaliza ndi njira zozizira zogwira ntchito monga kuzizira kozizira kapena kujambula kozizira kutentha.Mapaipi achitsulo oziziritsidwa amakhala ndi mawonekedwe owoneka bwino komanso osalala koma amatha kusokoneza.
Machubu achitsulo osasunthika otenthedwa otentha safuna chithandizo cha kutentha.
Machubu achitsulo osakanizidwa oziziritsidwa amatenthedwa pa kutentha kwa 1200°F [650°C] kapena kupitirira apo pambuyo powachiritsa komaliza.

Rockwell HardnessMtengo: 77HRBW
Kwa mapaipi achitsulo okhala ndi makulidwe a khoma osakwana 0.2" [5.1 mm].
Brinell Kuumamphamvu: 137HBW.
Kwa chitsulo chitoliro khoma makulidwe a 0.2" [5.1 mm] kapena kuposa.
Pazofunikira zina zogwirira ntchito, onani ASTM A450, Gawo 23.
· Mafupipafupi: Chitoliro chilichonse chachitsulo chimayesedwa ndi hydrostatic pressure test.
• Nthawi: Sungani kukakamiza kochepa kwa masekondi osachepera asanu.
Kuthamanga kwa madzi: Kuwerengeka pogwiritsa ntchito njira iyi.Zindikirani gawoli.
Inchi - Mapaundi Magawo: P = 32000 t/D
SI Mayunitsi: P = 220.6t/D
P = hydrostatic test pressure, psi kapena MPa;
t = makulidwe a khoma, mkati kapena mm;
D = kutchulidwa kunja kwake, mkati kapena mm.
· Zotsatira: Ngati palibe kutayikira mu mapaipi, mayeso amaonedwa kuti wadutsa.
Njira ina yoyeserera ya hydrostatic imathanso kuyesedwa koyenera kosawononga.
Komabe, muyezowu sunatchule kuti ndi njira iti yoyesera yosawononga yomwe ingagwiritsidwe ntchito.
Machubu akalowetsedwa mu chowotchera adzayima ndikukulitsa ndi kupendekera popanda kuwonetsa ming'alu kapena zolakwika.Machubu a superheater akagwiritsidwa ntchito moyenera aziyimilira ntchito zonse zopangira, kuwotcherera, ndi kupindika zofunikira pakugwiritsa ntchito popanda zovuta.
Botop Steelndi apamwamba welded mpweya zitsulo chitoliro wopanga ndi katundu kuchokera China, komanso msokonezo zitsulo chitoliro stockist, kukupatsani osiyanasiyana zitsulo chitoliro njira!
Lumikizanani nafepa mawu ochokera ku China seamless steel pipe stockist.
