ASTM A537 Kalasi 1,2,3 Boiler ndi Pressure chombo zitsulo mbale

Muyezo wa ASTM A537 umatanthawuza mbale zotengera zokakamiza, zakuthupi zomwe zimatenthedwa ndi kutentha, chitsulo cha silicon-manganese. Malingana ndi mphamvu zosiyanasiyana ndi chithandizo cha kutentha, zimayambira ku Kalasi 1, 2 ndi 3. Kukula kwakukulu pansi pa ASTM A537 Kalasi 1 ndi 100 mm [inchi 4], ndi 150 mm [inchi 6] kwa Kalasi 2 ndi Kalasi 3.
Maboiler a ASTM A537 Kalasi 1,2,3 Kufotokozera:
Mafotokozedwe a ASTM A537 ndi Standard Specification for Pressure Vessel Plates, Heat-Treated, Carbon-Manganese-Silicon Steel yomwe imagwiritsidwa ntchito popanga zotengera zophatikizika zophatikizika ndi zomangira. Zomwe zimagwiritsidwa ntchito ndi zombo zopanikizika zomwe zimapangidwira kuti zizitha kutentha pang'ono komanso zotsika zomwe zimafuna kulimba kwa notch komanso matanki osungira a API 650 ndi API 620. Zida za Class 1 zimapezeka ngati Zokhazikika ndipo Gulu 2 likupezeka ngati mbale Zozimitsidwa & Zotentha.

Zolemba Zotchulidwa

Miyezo ya ASTM:

A20/A20M: Mafotokozedwe Azofunikira Pazonse Pazamba za Pressure
A435/A435: Kwa Mayeso a Straight-Beam Ultrasonic a Steel Plate
A577/A577M: Kwa Akupanga Angle-Beam Mayeso a Zitsulo mbale
A578/A578M: ​​Pakuwunika kwa Beam-Beam Akupanga Kuyesa Kwambale Zazitsulo Zopiringizika za Mapulogalamu Apadera

Zolemba Zopanga:

Plate yachitsulo pansi pa ASTM A537 Kalasi 1, 2 ndi 3 idzaphedwa chitsulo ndikutsatira zofunikira za kukula kwambewu za Austenitic za Specification A20/A20M.

Njira Zochizira Kutentha:

Ma mbale onse pansi pa ASTM A537 azitenthedwa motere:
Mambale a ASTM A537 Class 1 azikhala okhazikika.
Mambale a Class 2 ndi Class 3 ayenera kuzimitsidwa ndi kutenthedwa. Kutentha kwa mbale za Class 2 sikuyenera kuchepera 1100 ° F [595 ° C] komanso kusachepera 1150 ° F [620 ° C] pa mbale za Class 3.
