A537 CL1 Mbale Wachitsulo Woponderezedwa Wokhazikika

Muyezo wa ASTM A537 umatanthawuza mbale zotengera zokakamiza, zakuthupi zomwe zimatenthedwa ndi kutentha, chitsulo cha silicon-manganese. Kutengera mphamvu zosiyanasiyana ndi chithandizo cha kutentha, zimayambira m'kalasi 1, 2 ndi 3.
Kukhuthala kwakukulu pansi pa ASTM A537 Kalasi 1 ndi 100 mm [inchi 4], ndi 150 mm [inchi 6] kwa Kalasi 2 ndi Kalasi 3.
Chitsulocho ndi chitsulo chokhazikika chomwe chimagwiritsidwa ntchito kutentha ndipo chifukwa chake chimawonetsa zokolola zambiri komanso mphamvu zolimba kuposa magiredi a ASTM A516. Chitsulocho ndi chabwino kuti chigwiritsidwe ntchito muutumiki wopanikizika onse mu boilers ndi zotengera zokakamiza

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.
