Mai i tōna whakatūnga i te tau 2014,Botop Steelkua noho hei kaiwhakarato matua o ngā paipa maitai waro i te Tai Tokerau 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 kore-tuia, ERW, LSAW, me SSAW, me te whānuitanga katoa o ngā hononga paipa me ngā flanges. Kei roto hoki i āna hua motuhake ngā koranu kounga teitei me ngā rino kowiri tira austenitic, i hangaia kia tutuki ai ngā hiahia o ngā kaupapa paipa rerekē.
Ka taea te hanga tui kore, te whakarewa rānei i ngā paipa maitai ASTM A53.
Ko te tikanga hanga hononga-kore (Momo S) he mahi wera i te rino, ā, ki te tika, he whakaotinga matao o te hua ngongo kua mahi wera kia whiwhi ai i te āhua, ngā rahinga me ngā āhuatanga e hiahiatia ana.
I roto i te paerewa ASTM A53, ko ngā whakaritenga hanganga matū mō te Momo S meMomo EHe rite tonu ngā paipa rino, engari he rerekē ngā whakaritenga hanganga matū mō te Momo F.

Whakamātautau Piko
Mō te DN ≤ 50 [NPS ≤ 2], me taea te piko matao i te roa o te paipa mā roto i te 90° huri noa i te mandrel porotaka, ko te whānui o taua paipa kia tekau mā rua ngā wā o te whānui o waho kua tohua o te paipa, me te kore e puta he kapiti i tētahi wāhanga.
Takirua-tino-kaha(XXS) kāore e hiahiatia kia whakamātauhia te piko o te paipa i runga ake i te DN 32 [NPS 1 1/4].
Whakamātautau Whakapapatahi
Kāore e hiahiatia kia whakamātauhia te whakapapatahi o ngā ngongo maitai tui kore.
Mena e hiahiatia ana e te kirimana, ka taea te whakahaere i te whakamātautau kia rite ki te tikanga kei roto i te S1.
Me pupuri e ngā paipa rino tui kore he pēhanga wai i tētahi taumata motuhake, me te kore e turuturu mō te iti rawa i te 5 hēkona.
Kei te Ripanga X2.2 te pēhanga whakamātautau mō ngā paipa maitai pito-kore.
Kei te Ripanga X2.3 ngā pēhanga whakamātautau mō ngā paipa maitai miro me ngā paipa honohono.
Ka taea te whakamahi hei huarahi kē atu ki te whakamātautau hydrostatic.
Me whakamātautau hiko kore-whakangaro te roanga katoa o ia paipa tui-kore, kia rite kiE213, E309, rāneiE570.
I te hoko i te ASTM A53, me tutuki i te rahi o te paipa maitai ngā whakaritenga e whai ake nei.

Ko te paerewa ASTM A53 e whakatau ana i ngā whakaritenga mō te āhua o te paipa mangu me te paninga konukōre wera-tuku o ngā paipa rino.
Paipa Pango
Ko te paipa pango e pā ana ki te āhua o te paipa maitai kāore he maimoatanga mata.
He maha ngā wā ka whakamahia ngā paipa pango ki ngā wāhi he poto te wā rokiroki, he maroke te taiao, ā, kāore e waikura, ā, he iti ake te utu nā te mea kāore he paninga.
Paninga Pirau wera-toia
Ko ngā paipa piauau, e mōhiotia ana ko ngā paipa mā, e whakamahia pinepinetia ana i ngā taiao makuku, waikura rānei.
Ka taea te whakamahi i te konutea i roto i te paninga konutea hei tetahi momo konutea i raro i te ASTM B6.
Me noho te paipa piauau kia kore he wāhi kāore i pania, he pupuhi, he putunga rere, me ngā paru matotoru. Kāore e whakaaetia ngā puku, ngā kokiri, ngā porowhita, ngā putunga nui rānei o te konutea ka whakararuraru i te whakamahinga o te rauemi.
Kāore e iti iho i te 0.55 kg/m² te nui o te konutea [1.8 oz/ft²].
Ētahi atu paninga
Haunga te paipa pango me te paninga piauau, ko ngā momo paninga noa kopeita, 3LPE, FBE, me ētahi atu. Ka taea te whiriwhiri i te momo paninga e tika ana kia rite ki ngā whakaritenga motuhake o te taiao mahi.
Mā te whakarato i ngā mōhiohio e whai ake nei ka pai ake, ka tika ake hoki tō tukanga hoko.
