JIS G 3454Ko te paerewa ahumahi Japanese mo nga putorino waro maitai mo nga punaha pehanga me te pāmahana whakahaere teitei o te 350°C.Kei roto i te paerewa e rua nga tohu:STPG 370aSTPG 410.E pa ana ki nga paipa paiherea hiko (ERW) me nga putorino tuitui me te 10.5 mm ki te 660.4 mm te diameter (ara 6A ki te 650A, 1/8B ki te 26B ranei).
JIS G 3454 Ko nga paipa rino ka hangaia ma te whakamahi i te huinga tika o nga tikanga hanga paipa maitai me nga tikanga whakaoti i te ripanga i raro nei.

Whakamātautau Whakapapa
Ka tae te tawhiti i waenga i nga papa e rua ki te tawhiti H kua tohua, kaore he hapa, he kapiti ranei i runga i te mata o te paipa maitai.
Mo nga ngongo maitai tuitui: H = (1+e)t/(e + t/D);
Mo nga paipa rino ERW: H = 1/3 D (mo te weld) ranei H = 2/3 D (mo te waahanga kaore he weld);
H: te tawhiti i waenga i nga papa papatahi (mm);
е: te tautuhi takitahi mo ia reanga paipa, 0.08 mo STPG 370, 0.07 mo STPG 410;
t: te matotoru o te pakitara o te paipa (mm);
D: te diameter o waho o te paipa (mm);
E tika ana te Whakamatau Whakapapa ki nga paipa rino he rahi ake i te 40A (48.6mm) te diameter.
Te whakapiko
Ko te kaha o te piko ka pa ki nga paipa e 40 A (48.6), iti ake ranei te diameter.
Me whakapiko te putorino kia 90° i te radius e 6 nga wa o tona diameter o waho.Ko te pakitara paipa me kore he koha, he kapiti ranei.
Ko ia putorino maitai me uru ki te whakamatautau pehanga hydrostatic, ki te whakamatautau kore-whakangaro ranei.
Whakamātautau Hydrostatic
Kia mau tonu te pehanga mo te 5 hēkona iti rawa kia kore e pakaru.
Ko te uara pehanga e pa ana ki te raarangi Nama o te paipa maitai.
