Ixabiso lombhobho wentsimbi eyi-6 yentsimbi iphakamile kunelo kumbhobho wentsimbi eyi-12 yentsimbi kuba umbhobho wentsimbi eyi-6 unendleko zokucheba umbhobho, umlenze wentloko, njl. Njl.
Xa uthenga imibhobho yentsimbi engenamthungo, cinga ngomehluko. Umzekelo, ubukhulu becala lombhobho wensimbi kunye nobubanzi beI-ASTM A106 GRBI-159 * 6 inokuba ngu-159 * 6.2 Ngobubanzi bodonga lwe-6.2 mm. Ukuba umahluko awuthathelwa ingqalelo, intlawulo iya kuhlawulelwa ngaphezulu xa ubunzima buzinzile. Nangona kunjalo, inkqubo yangoku yemveliso yangoku ayinakuphumelela umahluko, nto leyo yokuphucula okukhulu kumzi mveliso wentsimbi engenamthungo.
Imibhobho emininzi yentsimbi engenamthungo ayikho ngaphezulu. Ezinye zinokuba ziimitha ezingama-8-9, iimitha ezisisi-8,5, iimitha ezisisi-8,3, okanye ezi-8,4 zeemitha, kodwa ungazixela iifoto zempahla nokuba ilungisiwe okanye akunjalo. Umzekelo, le bhetch yempahla ilandelayo ilungisiwe ubude beemitha ezili-12 kwaye zenziwa kakuhle kakhulu.
Xa uthumela ububanzi be-diameter kunye nemibhobho yentsimbi enesithukuthezi emthungo, kufuneka sinikele ingqalelo ekuzibethelele ngaphezulu ngexesha lokuhamba ukuze sibathintele. Kufuneka sihlawule eyona ingqalelo kwaye ikhathazeke ngomgangatho wemveliso. Kufuneka siqinisekise ukuba abathengi banokusebenzisa impahla yabo ngokuzithemba xa befika kwindawo yokwakha kwaye banako ukuhlola umgangatho kunye nokwamkelwa okusemgangathweni. Le yeyona njongo yethu ibaluleke kakhulu, ngoko kufuneka sinike ingqalelo kwaye sikhathazeke ngomgangatho wemveliso.
IXESHA LOKUQALA: AUG-15 ukuya ku-2004
