Ngathi
Uluhlu lweDiameter
I-ASTM A179 yeetyhubhu ezinobubanzi obungaphandle phakathi kwe-3.2 -76.2 mm [NPS 1/8 - 3 in.].
Unyango lobushushu
Ubushushu bunyangwa kwi-1200℉ [650℃] okanye ngaphezulu emva kwepaseji yokufunxa ebandayo yokugqibela.
Imbonakalo
Umbhobho wentsimbi ogqityiweyo awuyi kuba nesikali.I-oxidation encinci ayithathwa njengesikali.
Ukunyamezelwa kweDimensional

| Ukuthe tye kwaye Gqiba | Iityhubhu ezigqityiweyo ziya kuthi nkqo ngokufanelekileyo kwaye zibe neziphelo ezigudileyo ezingenazo iibhara. | |
| Ukuphatha isiphene | Nakuphi na ukungaqhubeki okanye ukunganyaniseki okufunyenwe kwityhubhu kunokususwa ngokusila, ngaphandle kokuba indawo egudileyo egobileyo igcinwe, kwaye ubuninzi bodonga abuncitshiswanga bube bungaphantsi kokuvunyelwa yile nto okanye inkcazo yemveliso. | |
I-ASTM A179 ifomula yobunzima yile:
M=(DT)×T×C
Mbubunzima ngeyunithi yobude;
Dyi-diameter yangaphandle echaziweyo, echazwe ngeemilimitha (ii-intshi);
T ubukhulu bodonga obuchaziweyo, bubonakaliswe ngeemilimitha (ii-intshi);
Cyi 0.0246615 ukubala kwiiyunithi SI kunye 10.69 ukubala kwiiyunithi USC.
