Ixabiso le-6-meter ye-ipayipi yensimbi engenamthungo iphezulu kuneyombhobho yensimbi engenamthungo yeemitha ezili-12 ngenxa yokuba umbhobho wensimbi we-6-mitha uneendleko zokusika umbhobho, umphetho wesikhokelo sentloko, ukuxhoma, ukufumanisa impazamo, njl njl. .

Xa uthenga iibhobho zentsimbi ezingenamthungo, qwalasela umahluko. Umzekelo, ubukhulu bodonga lombhobho wentsimbi kunye nobubanzi obungaphandleI-ASTM A106 GrBI-159 * 6 ingaba yi-159 * 6.2 kunye nobukhulu bodonga lwe-6.2 mm. Ukuba umahluko awuqwalaselwanga, intlawulo iya kuhlawulwa ngaphezulu xa ubunzima buxazululwe. Nangona kunjalo, inkqubo yokuvelisa yangoku ayinakufezekisa umahluko, ophuculo olukhulu kwishishini lombhobho wensimbi engenamthungo.

Imibhobho emininzi yentsimbi engenamthungo ayilungiswanga ngobude. Ezinye zinokuba yi-8-9 yeemitha, i-8.5 yeemitha, i-8.3 yeemitha, okanye i-8.4 yeemitha, kodwa unokwazi ukusuka kwiifoto zeempahla ukuba zilungisiwe okanye hayi. Umzekelo, ibhetshi elandelayo yempahla ilungiswe kubude beemitha ezili-12 kwaye yenziwe ngokucokisekileyo.
