| I-ASTM A53 | Umbhobho wentsimbi ongagqunywanga kunye noshushu odiphuliweyo kunye nomthungo wentsimbi | Kwimibhobho yegama elingaphantsi okanye elilingana ne-NPS 1 1/2(DN40), ububanzi bayo nayiphi na indawo ayisayi kuba nkulu kunexabiso eliqhelekileyo le-1/64 kwi-(0.4mm), kwiityhubhu ezibizwa ngokuba zinkulu okanye zilingana ne-NPS2(DN50), idayamitha yangaphandle ayisayi kudlula ixabiso eliqhelekileyo le-±1% | Ubuncinci bodonga olungqingqwa kuyo nayiphi na indawo abuyi kuba ngaphezulu kwe-12.5% ubukhulu kunobumba obuxeliweyo obuchaziweyo. Ubuncinane bodonga obujongiweyo buya kuhlangabezana neemfuno ezikwiTheyibhile X2.4 | Ubunzima bombhobho wegama obuchazwe kwiiThebhile X2.2 kunye ne-X2.3, okanye ubunzima obubalwe ngokwefomula efanelekileyo kwi-ASME B36.10M, abuyi kuphambukiswa ngaphezu kwe-±10% |

Ngaphandle kokuba kuvunyelwene ngenye indlela ngumthengisi kunye noXu Fang, iipayipi zentsimbi ezine-NPS ye-4 kunye nezincinci zinokulinganiswa ngokufanelekileyo kwiibhetshi. |
