| I-ASTM A53 | Ipayipi lensimbi elingamboziwe nelishisayo elihlanganisiwe nelingenamthungo | Kumashubhu ajwayelekile angaphansi noma alingana ne-NPS 1 1/2(DN40), ububanzi banoma iyiphi indawo akufanele bube ngaphezu kwenani elijwayelekile elingu-1/64 in(0.4mm), kumashubhu ajwayelekile amakhulu noma alingana ne-NPS2(DN50), ububanzi bangaphandle akufanele budlule inani elijwayelekile elingu-±1% | Ubukhulu bodonga obuncane kunoma iyiphi indawo akumele bube ngaphezu kuka-12.5% kunobukhulu bodonga obubekiwe. Ubukhulu bodonga obuncane obuhloliwe buzohlangabezana nezidingo eziseThebula X2.4 | Isisindo sepayipi elijwayelekile elichazwe kuThebula X2.2 kanye no-X2.3, noma isisindo esibalwe ngokwefomula efanele ku-ASME B36.10M, akufanele siphambukiswe ngaphezu kuka-±10% |
| I-ASTM A106 | Ipayipi elisezingeni eliphezulu lensimbi yekhabhoni engenamthungo | 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 obuncane kunoma iyiphi indawo akumele budlule u-12.5% wobukhulu bodonga obucacisiwe bobunjiniyela | Isisindo sanoma yiliphi ipayipi lensimbi akumele sidlule u-10% noma ngaphezulu kwesisindo esinqunyiwe, futhi akumele sibe ngaphansi kuka-3.5% noma ngaphezulu. Ngaphandle kokuthi kuvunyelwene ngenye indlela ngumhlinzeki kanye no-Xu Fang, amapayipi ensimbi ane-NPS engu-4 kanye nencane angalinganiswa kahle ngamaqoqo. |
