Ħarsa ġenerali lejn ASTM A312 Pajp ta 'l-Azzar li ma jsaddadx mingħajr saldatura
Il-grad ASTM A312 ikopri l-grad standard tal-pajp tal-istainless steel. Il-Pipe ASTM A312 għandu elementi ta 'liga bħal kromju, nikil, ram, molibdenu, eċċ, li jagħtihom tolleranza u reżistenza eċċellenti għall-midja korrużiva u ossidattiva f'setups indotti mill-istress. Il-grad versatili jkopri mingħajr saldatura, firxa ta 'azzar inossidabbli awstenitiku wweldjat maħdum ħafna kiesaħ u moduli ta' pajpijiet ta 'weldjatura dritta. L-ASTM A312 Skeda 40 Pipe huwa maħsub għall-użu f'temperaturi għoljin u jidher komunement f'sistemi ta 'pressjoni moderata. Il-pajp sch 40 huwa skeda komuni dan il-pajp huwa disponibbli fl-industrija. Il-Pipe ASME SA12 huwa grad ta 'pajp ta' bastiment taħt pressjoni ddisinjat għal setups ta 'pressjoni u temperatura elevati. Dawn il-moduli għandhom saħħa tajba u ma jgħawġux jew jgħawġu faċilment fl-ebda ċirkostanza.

Tipi ta 'Manifattura ta' Pajpijiet ASTM A312
l Pajp mingħajr saldatura (SMLS): Ikopri pajp jew tubu mingħajr saldatura ta 'l-istainless steel f'irrumblar bis-sħana jew miġbud fil-kesħa.
l Pajp Iwweldjat (WLD): Iwweldjat permezz ta 'proċess ta' wweldjar awtomatiku li ma jżidx metall tal-mili waqt l-iwweldjar.
l Cold Worked Pipe (pajp HCW): Il-pajp tqil maħdum bil-kesħa li japplika xogħol kiesaħ ta 'mhux inqas minn 35% tnaqqis fil-ħxuna taż-żewġ ħajt, u wweldjat mal-pajp iwweldjat qabel l-ittemprar finali. Tużax fillers waqt l-iwweldjar.
l Pajp iwweldjat u HCW: Pajp iwweldjat u pajp HCW ta '14 u iżgħar minn NPS 14 għandu jkollhom weldjatura lonġitudinali waħda. Wara l-approvazzjoni mix-xerrej, il-pajp iwweldjat u l-pajp HCW b'NPS akbar minn NPS 14 għandu jkollhom weldjatura lonġitudinali waħda jew għandhom jiġu manifatturati billi jiġu ffurmati u wweldjati żewġ sezzjonijiet lonġitudinali ta 'stokk ċatt. Allura kull weldjatura għandha tiġi ttestjata, spezzjonata, spezzjonata jew ittrattata.
