I-ASTM A537 Class 1,2,3 Boiler kanye nepuleti lensimbi lomkhumbi we-Pressure

Ukucaciswa kwe-ASTM A537 Ukucaciswa Okujwayelekile Kwamapuleti Omkhumbi Wengcindezi, Aphethwe Ukushisa, Insimbi Ye-Carbon-Manganese-Silicon esetshenziswa ekusetshenzisweni kwemikhumbi yengcindezi ehlanganisiwe ehlanganisiwe nezakhiwo. Izinhlelo zokusebenza ezijwayelekile ziyimikhumbi yokucindezela eklanyelwe isevisi yezinga lokushisa elimaphakathi neliphansi edinga ukuqina kwenotshi okuhle kakhulu kanye namathangi okugcina e-API 650 kanye ne-API 620. Izinto ze-Class 1 zitholakala njenge-Normalized futhi I-Class 2 itholakala njengamapuleti aQuenched & Tempered.

Amadokhumenti Akhonjiwe

Amazinga e-ASTM:

A20/A20M: Ukucaciswa Kwezimfuneko Ezivamile Zamapuleti Omkhumbi Wokucindezela
I-A435/A435: Ukuhlolwa kwe-Straight-Beam Ultrasonic kwePlate Lensimbi
I-A577/A577M: Yokuhlolwa kwe-Ultrasonic Angle-Beam yamaPlate Ensimbi
I-A578/A578M: ​​Ukuze Uhlolwe I-Straight-Beam Ultrasonic Yamapuleti Ensimbi Agingqelwe Ngezicelo Ezikhethekile

Amanothi Okukhiqiza:

I-Steel Plate ngaphansi kwe-ASTM A537 Ikilasi 1, 2 no-3 izobulawa insimbi futhi ithobelane nemfuneko kasayizi wokusanhlamvu we-austenitic omuhle we-Specification A20/A20M.

Izindlela Zokwelapha Ukushisa:

Wonke amapuleti angaphansi kwe-ASTM A537 azophathwa ngokushisa ngale ndlela elandelayo:
Amapuleti e-ASTM A537 Class 1 azokwenziwa abejwayelekile.
Amapuleti e-Class 2 kanye ne-Class 3 azocishwa futhi aqinise. Izinga lokushisa elishisayo lamapuleti e-Class 2 akufanele libe ngaphansi kuka-1100°F [595°C] futhi lingabi ngaphansi kuka-1150°F [620°C] emapuletini eSigaba sesi-3.
