Ibanga Lobubanzi
I-ASTM A179 yamashubhu anobubanzi bangaphandle obuphakathi kuka-3.2 -76.2 mm [NPS 1/8 - 3 in.].
Ukwelashwa Kokushisa
Ukushisa kwelashwa ku-1200℉ [650℃] noma ngaphezulu ngemva kokumuncwa okubandayo kokugcina.
Ukubukeka
Ipayipi lensimbi eliqediwe akufanele libe nesikali.I-oxidation encane ayibhekwa njengesikali.
I-Dimensional Tolerances

| DN≥50.8mm[NPS 2] | +3mm[NPS 1/8] | |
| Ukuqondile futhi Qeda | Amashubhu aqediwe kufanele aqonde ngokufanelekile futhi abe neziphetho ezibushelelezi ezingenazo ama-burrs. | |
| Ukuphatha iphutha | Noma yikuphi ukungaqhubeki noma okungajwayelekile okutholakala kushubhu kungase kususwe ngokugaya, inqobo nje uma kugcinwa indawo ebushelelezi egobile, futhi ukujiya kodonga akwehliswa kube ngaphansi kwalokho okuvunyelwe yilokhu noma ukucaciswa komkhiqizo. | |
Ifomula yesisindo ye-ASTM A179 ithi:
M=(DT)×T×C
Mubukhulu beyunithi ngayinye;
Diwububanzi obushiwo bangaphandle, obuvezwa ngamamilimitha (amayintshi);
T ubukhulu bodonga olucacisiwe, obuvezwa ngamamilimitha (amasentimitha);
Cingu-0.0246615 yezibalo zamayunithi e-SI kanye no-10.69 wezibalo zamayunithi e-USC.
