Ububanzi Bebanga
I-ASTM A179 yamashubhu anobubanzi obungaphandle obuphakathi kuka-3.2 -76.2 mm [NPS 1/8 - 3 in.].
Ukwelashwa Kokushisa
Ukushisa kulungiswe ku-1200℉ [650℃] noma ngaphezulu ngemva kokudlula kokugcina kokumunca umkhuhlane.
Ukubukeka
Ipayipi lensimbi eliqediwe akufanele libe nesikali. Ukushiswa okuncane akubhekwe njengesikali.
Ukubekezelelana Okulinganayo

| Ukuqonda Nokuqeda | Amashubhu aqediwe kufanele aqonde kahle futhi abe neziphetho ezibushelelezi ezingenama-burrs. | |
| Ukuphathwa kahle kwamaphutha | Noma yikuphi ukungaqhubeki noma ukungahleleki okutholakala epayipini kungasuswa ngokugaya, uma nje indawo egobile ebushelelezi igcinwa, futhi ubukhulu bodonga bungancishiswa bube ngaphansi kwalokho okuvunyelwe yilokhu noma incazelo yomkhiqizo. | |
Ifomula yesisindo se-ASTM A179 yile:
M=(DT)×T×C
Mubude besisindo ngeyunithi ngayinye;
Dububanzi obucacisiwe bangaphandle, obuvezwa ngamamilimitha (amasentimitha);
