ZaZida za chitoliro cha ASTM A234 WPB
ASTM A234 ndi Mafotokozedwe Okhazikika azitsulo zamapaipi achitsulo amaphatikizapo zinthu zachitsulo za carbon ndi alloy pa ntchito zolimbitsa thupi komanso kutentha kwambiri.Zimakwirira zitsulo zamitundu yopanda msoko komanso yowotcherera.Zopangira zachitsulo zachitsulo zimagwiritsidwa ntchito pamapaipi oponderezedwa komanso pamapaipi oponderezedwa.Zida zopangira izi zimakhala ndi zitsulo zophedwa, zopangira, mipiringidzo, mbale, zopanda msoko kapena HFW (fusion welded) zida zamapaipi, zowonjezeredwa zitsulo.
WPB ndi chiyani?
W = WELDABLE / wopangidwa
P = ZOKHUDZANA NDI P NUMBER YA CHIKWANGWANI CHA Alloy
B = KUTANTHAUZIRA KU ZONSE ZONSE ZONSE ZONSE ZONSE
Akupezeka mukusintha kwaposachedwa kwa ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, ndi MSS-SP-97.Amagwiritsidwanso ntchito kwambiri popanga mapaipi oponderezedwa komanso popanga zotengera zokakamiza kuti azigwira ntchito pamatenthedwe apakati komanso okwera.Maphunzirowa ndi ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 ndi WP22.
Zofotokozera:
Miyezo: ANSI /ASME B16.9, B16.28, MSS-SP-43.
Kunja Diameter Range: 1/2 "mpaka 48"
Makulidwe osiyanasiyana: SCH 10, sch 20, SCH 40, SCH STD, SCH 80, SCH XS, SCH 160, SCH XXS etc.
Mitundu yopangira mapaipi achitsulo mu forged, threaded, butt weld, and seamless.
