| I-ASTM A53 | Umbhobho wesinyithi odityanisiweyo nongenamthungo ongenanto kwaye ongenamthungo, ogqunywe ngentsimbi eshushu | Kwiityhubhu ezimiselweyo ezingaphantsi okanye ezilingana ne-NPS 1 1/2 (DN40), ububanzi bayo nayiphi na indawo abuyi kuba ngaphezu kwexabiso eliqhelekileyo le-1/64 in (0.4mm), kwiityhubhu ezimiselweyo ezingaphezulu okanye ezilingana ne-NPS2 (DN50), ububanzi bangaphandle abuyi kudlula ixabiso eliqhelekileyo le-±1% | Ubukhulu bodonga obuncinci nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% kunobukhulu bodonga obuchaziweyo. Ubukhulu bodonga obuncinci obujongiweyo buya kuhlangabezana neemfuno ezikwiTheyibhile X2.4 | Ubunzima bombhobho oqhelekileyo obuchazwe kwiiTheyibhile X2.2 kunye neX2.3, okanye ubunzima obubalwe ngokwefomula efanelekileyo kwi-ASME B36.10M, abuyi kuphambukiswa ngaphezulu kwe-±10% |
| I-ASTM A106 | Umbhobho wesinyithi wekhabhoni oshushu ophezulu | 1/8-1 1/2 ±0.4mm, ＞1 1/2-4 ±0.79mm ＞4-8 ﹢1.59mm -0.79mm ＞8-18 ﹢2.38mm -0.79mm ＞18-26 ﹢3.18mm -0.79mm ＞26-34 ﹢3.79mm ﹣0.79mm ＞34-48 +4.76mm -0.79mm | Ubukhulu bodonga obuncinci nakweyiphi na indawo abuyi kudlula i-12.5% yobukhulu bodonga obuchaziweyo bobunjineli | Ubunzima balo naliphi na ipayipi yentsimbi abuyi kudlula i-10% okanye ngaphezulu kobunzima obumiselweyo, kwaye abuyi kuba ngaphantsi kwe-3.5% okanye ngaphezulu. Ngaphandle kokuba kuvunyelwene ngenye indlela ngumthengisi kunye no-Xu Fang, iipayipi zentsimbi ezine-NPS ezi-4 nezincinci zinokulinganiswa ngokufanelekileyo ngeebhetshi. |
