Ingano y'umurambararo
ASTM A179 ku miyoboro ifite umurambararo wo hanze uri hagati ya mm 3.2 na 76.2 [NPS 1/8 - 3 in.].
Uburyo bwo kuvura ubushyuhe
Ubushyuhe bwavuwe kuri 1200℉ [650℃] cyangwa hejuru yayo nyuma yo gukurura ubukonje bwa nyuma.
Isura
Umuyoboro w'icyuma urangiye ntugomba kugira igipimo. Oxidation nto ntabwo ifatwa nk'igipimo.
Ubwihangane mu Bipimo
| Ubwihangane mu Bipimo | ||
| Urutonde | Tondeka | Igipimo |
| Misa | DN≤38.1mm [NPS 11/2] | + 12% |
| DN ＞38.1mm [NPS 11/2] | + 13% | |
| Ingano | DN≤38.1mm [NPS 11/2] | + 20% |
| DN ＞38.1mm [NPS 11/2] | + 22% | |
| Uburebure | DN <50.8mm [NPS 2] | +5mm [NPS 3/16] |
| DN≥50.8mm [NPS 2] | +3mm [NPS 1/8] | |
| Kugororoka no Kurangiza | Imiyoboro irangiye igomba kuba igororotse kandi ifite impera zoroshye zidafite uduce duto. | |
| Gukoresha neza inenge | Uguhagarara cyangwa ubusumbane ubwo aribwo bwose buboneka mu muyoboro bushobora gukurwaho hakoreshejwe gusya, mu gihe ubuso bworoshye buhora bumeze neza, kandi ubugari bw'urukuta ntibugabanuke ngo bugere munsi y'ubwo byemejwe n'ibi cyangwa ibipimo by'umusaruro. | |
Ifishi y'uburemere ya ASTM A179 ni:
M=(DT)×T×C
Mni uburemere kuri buri gice cy'uburebure;
Dni umurambararo w'inyuma wavuzwe, ugaragazwa muri milimetero (inchi);
T ni ubugari bw'urukuta bwagaragajwe, bugaragazwa muri milimetero (inchi);
Cni 0.0246615 ku mibare mu bice bya SI na 10.69 ku mibare mu bice bya USC.
Niba ushaka kumenya byinshi ku byerekeye ameza y'uburemere bw'imiyoboro y'icyuma n'ingengabihe,kanda hano!
