JIS G 3444: Ngā ngongo maitai waro mō te hanganga whānui.
E whakatau ana i ngā whakaritenga mō ngā paipa maitai waro e whakamahia ana i roto i te hangarau ā-iwi me te hanganga, pērā i ngā pourewa maitai, ngā tūāpapa, ngā pou turanga, ngā pou turanga, me ngā pou ārai-paheke.
STK 400Ko te paipa rino tētahi o ngā momo tino noa, me ōna āhuatanga miihini o tete kaha kume iti rawa o te 400 MPame tete kaha whakaputa iti rawa o te 235 MPa. He pai tōna kaha hanganga me tōna roakia pai ai mō ngā tono maha.
E ai ki te kaha kume iti rawa, e rima ngā akomanga o te paipa maitai, arā:
STK 290, STK 400, STK 490, STK 500, STK 540.
Whānui te whānui o waho: 21.7-1016.0mm;
Ngā pou turanga me ngā puranga hei pehi i te horo whenua OD: i raro i te 318.5mm.

Me hanga ngā ngongo mā te whakamahi i te huinga o te tikanga hanga ngongo me te tikanga whakaoti e tohua ana.
Ina koa, ka taea te whakarōpū i ēnei ki ngā momo e whitu e whai ake nei, nō reira whiriwhiria te momo e tika ana kia rite ki ngā hiahia rerekē:
1) Ngongo maitai kore-whakaoti wera: -SH
2) Ngongo maitai kore-whakaoti matao: -SC
3) Hei ngongo maitai whakarewa ātete hiko: -EG
4) Ngongo maitai hiko ātete wera kua oti te whakarewa: -EH
5) Ngongo maitai whakarewa ātete hiko kua oti te whakamatao: -EC
6) Ngā ngongo maitai i whakapirihia ki te papa: -B
7) Ngā ngongo maitai whakarewa ā-aunoa: -A

STK 400He maitai waro-iti te maitai, he pai te whakarewa me te mahi mō ngā tono hanganga e hiahia ana kia whakarewahia. Ka whakahaeretia te whākawa me te whanariki i ngā taumata iti hei āwhina i te pupuri i te pakari me te mahi whānui o te rauemi. Ahakoa kāore i hoatuhia ngā uara motuhake mō te silicon me te manganese, ka taea te whakarerekē i roto i ngā rohe e whakaaetia ana hei whakapai ake i ngā āhuatanga o te maitai.
Te Kaha Kume me te Pūwāhi Tuku, te Taumahatanga Whakamātautau rānei
Ka pā te kaha kume o te whakarewa ki ngā ngongo whakarewa pewa aunoa. Koinei te tukanga whakarewa SAW.

Te whakaroa o JIS G 3444
Ko te roa e pā ana ki te tikanga hanga ngongo e whakaaturia ana i te Ripanga 4.
Heoi, ina whakahaerehia te whakamātautau kume ki te Wāhanga Whakamātautau Nama 12, ki te Wāhanga Whakamātautau Nama 5 rānei i tangohia mai i te ngongo i raro i te 8 mm te matotoru o te pakitara, me rite te roa ki te Ripanga 5.
I te pāmahana rūma (5 °C ki te 35 °C), whakatakotoria te tauira ki waenganui i ngā pereti papatahi e rua, ka pēhi kia pakari kia papatahi kia tae rā anō ki te tawhiti H ≤ 2/3D i waenganui i ngā pereti, kātahi ka tirohia mēnā he pakaru kei roto i te tauira.
I te pāmahana rūma (5 °C ki te 35 °C), pikohia te tauira huri noa i tētahi rango i te koki piko iti rawa o te 90° me te radius ā-roto mōrahi kaua e neke atu i te 6D, ā, tirohia te tauira mō ngā pakaru.
Me whakaae wawe ki ngā whakamātautau waipū, ngā whakamātautau kore-whakangaro o ngā whakarewa, me ētahi atu whakamātautau rānei, mō ngā whakaritenga e tika ana.

Me maeneene ngā mata o roto, o waho hoki o te paipa rino, ā, me karekau he hapa e kino ana ki te whakamahinga.
Me tāpiri ngā mōhiohio e whai ake nei ki ia paipa rino.
a)Tohu o te māka.
b)Tohu mō te tikanga hanga.
c)Ngā Ahu.Me tohu te whānui o waho me te matotoru o te pakitara.
d)Ingoa, whakarāpopototanga rānei o te kaihanga.
Mēnā he uaua te tohu i runga i te ngongo nā te mea he iti tōna whānui o waho, mēnā rānei e tonoa ana e te kaihoko, ka taea te hoatu te tohu ki ia paihere ngongo mā te huarahi e tika ana.
Ka taea te pani i ngā paninga ārai-waikura pērā i ngā paninga whai-konutea, ngā paninga epoxy, ngā paninga peita, me ētahi atu, ki ngā mata o waho, o roto rānei.
He pai te taurite o te kaha me te ōhanga o te STK 400, he mea tino pai mō ngā kaupapa hangarau me te hanga maha.
E whakamahia whānuitia ana ngā ngongo maitai STK 400 i roto i te umanga hanga, ā, he tino pai mō te whakamahi hei wāhanga hanganga pēnei i ngā pou, ngā kurupae, ngā anga rānei i roto i ngā whare arumoni me ngā whare noho.
He pai hoki mō ngā piriti, ngā hanganga tautoko, me ētahi atu kaupapa e hiahia ana ki te kaha me te roa waenga.
Ka taea hoki te whakamahi hei hanga i ngā ārai rori, i ngā anga tohu huarahi, me ētahi atu whakaurunga tūmatanui.
I roto i te mahi hanga, ka taea te whakamahi i te STK 400 hei whakaputa anga me ngā hanganga tautoko mō ngā mīhini me ngā taputapu nā te mea he pai tōna kaha ki te pikau kawenga me tōna ngāwari ki te mahi.
Kia mōhio mai, ahakoa he rite te whakamahinga me te mahi o ēnei paerewa, tera pea he rerekētanga iti i roto i te hanganga matū me ētahi tawhā āhuatanga ā-pūkaha.
I te wā e whakakapi ana i ngā rauemi, me whakataurite taipitopito ngā whakaritenga motuhake o ngā paerewa kia tino tutuki ai ngā rauemi kua tīpakohia ki ngā paerewa hangarau me te haumaru motuhake o te kaupapa.
Mai i tōna whakatūnga i te tau 2014, kua noho a Botop Steel hei kaiwhakarato matua o ngā paipa maitai waro i te raki o Haina, e mōhiotia ana mō te ratonga pai rawa atu, ngā hua kounga teitei, me ngā otinga whānui.
He maha ngā momo paipa rino waro me ngā hua e pā ana ki tēnei kamupene, tae atu ki ngā paipa rino tuia, ERW, LSAW, me te SSAW, tae atu ki te whānuitanga katoa o ngā hononga paipa me ngā flange.
Kei roto hoki i ana hua motuhake ngā koranu kounga teitei me ngā maitai kore waikura austenitic, i hangaia kia tutuki ai ngā hiahia o ngā kaupapa paipa rerekē.
