Ko nga tohu kei roto te reta, H, i roto i to raatau tohu, he rereke nga whakaritenga mai i era o nga reanga rite kaore i te reta. , H. Ko enei whakaritenga rereke e whakarato ana i te kaha o te ngokingoki-nui atu i te tikanga ka taea i roto i nga reanga rite kaore enei whakaritenga rereke.
Ko nga rahi me te matotoru o nga ngongo ka tukuna ki tenei waahangafko te cation he 1⁄8 inihi [3.2 mm] te whanui o roto ki te 5 inihi [127 mm] te whanui o waho me te 0.015 ki te 0.500 inihi. [0.4 ki te 12.7 mm], tae atu ki te iti rawa o te matotoru o te pakitara, ki te mea he tohu.fed i roto i te raupapa, toharite matotoru pakitara.Ko nga ngongo me etahi atu diameter ka taea te whakawhiwhi, mena ka tutuki enei ngongo ki nga whakaritenga katoa o tenei waahangafcation.

Nga whakaritenga hangarau acc.ki ASTM A 450.
Te rahi o nga paipa kia rite ki te ANSI/ASME B36.19M.
Ko te kounga o nga paipa ka whakapumautia e te mahi hangahanga me te whakamatautau kore-whakangaro.
Te pakeke o te whakarewa kaua e iti iho i te 100 HB.
Ko te roa o nga paipa ine kare i nui ake i te +10 mm.
Ko te aro turuki i te haere tonu o te whakarewa ma te pneumotest me te pehanga 6 pae e waatea ana.
Ko te whakamatautau waikura intergranular i runga i te ASTM A262, Kei te waatea te Mahinga E.

（1）Ko nga ngongo rino kua oti te makariri kia kore he unahi, he pai hoki mo te tirotiro, he iti te pikinga o te waikura kaore i te tauine.
（2）Ko nga ngongo rino kua oti te wera me te kore he tauine, he pai mo te tirotiro.
（3）Ka kohia nga ngongo rino kore utu i te tauine, ka whakamahia te whakamaarama kanapa, kare e tika te kohi.
（4）Ko nga whakaritenga whakaoti motuhake me whakaae ki waenga i te kaiwhakarato me te kaihoko.
