AboutASTM A234 WPB pombi fittings
ASTM A234 ndiyo Yakajairwa Kutsanangurwa kwesimbi pombi fittings inosanganisira kabhoni uye alloy simbi zvinhu zvine mwero uye yakakwirira tembiricha masevhisi.Inovhara simbi dzesimbi dzemhando dzisina musono uye dzakasungwa.Simbi Pipe fittings inoshandiswa mumapombi ekumanikidza uye mukumanikidza ngarava machira.Izvi zvekugadzirisa zvinhu zvinosanganisira simbi yakaurayiwa, forging, mabara, mahwendefa, isina musono kana HFW (fusion welded) zvigadzirwa zvepombi, nesimbi yekuzadza yakawedzerwa.
Chii chinonzi WPB?
W = WELDABLE / yakagadzirwa
P = ZVAKAENDERERA P NUMBER YEVAKASIYANA
B = ITAI KUNE ZVINOGONA KUBVA ZVINHU
Anowanikwa mukuvandudzwa kwazvino kweASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, uye MSS-SP-97.Zvakare inoshandiswa zvakanyanya mukumanikidza pombi uye mukumanikidza ngarava kugadzirwa kwesevhisi kune yakadzikama uye yakakwira tembiricha.Magiredhi anoti ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 neWP22.
Zvinodiwa:
