Kei roto i te whānuitanga o ngā hua ngā paipa rino kore hononga, ko ngā diameter o waho kei waenganui i te 10.3 - 660 mm me ngā matotoru kei waenganui i te 2 - 100 mm.
Neke atu i te 8,000 tāne o ngā paipa maitai kore hononga kei roto i te taonga, ā, ka taea e mātou te whakarite kia tukuna wawetia ngā rahi noa. Mō ngā momo me ngā rahi motuhake, ka tukuna atu hoki e mātou he ratonga whakaputa ritenga hei whakatutuki i ngā hiahia motuhake o te kiritaki.
Ngā ngongo maitai kore-tuituie rua ngā tukanga matua e hangaia ana: te whakaotinga wera me te tuhi matao.
Ka taea e te DN ≤ 40 te hanga i te mea kua oti te wera, te mea kua oti te matao rānei, ko te nuinga he mea kua oti te matao.
Me whakaoti wera te DN ≥ 50. E wātea ana hoki ngā ngongo maitai kore-hono e kumea ana i te matao ina tonoa.

Hei whakarite kia tutuki i te paipa ngā whakaritenga hanganga matū o te Wāhanga B o ngā paerewa e toru, arā, te API 5L, te ASTM A106, me te ASTM A53, me tino aroturuki te hanganga matū o te rauemi i te wā e hangaia ana. Ko ngā whakaritenga motuhake mō te hanganga matū o ēnei paerewa e toru ēnei e whai ake nei:
Hanganga Matū API 5L Tau B
Te Hanganga Matū ASTM A106 Tau B
Te Hanganga Matū ASTM A53 Tau B
| Whakamātautau | API 5L PSL1 Tau B | ASTM A106 Tau B | ASTM A53 Tau B | |
| Te kaha o te tuku, min | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Kaha kume, min | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Mā te whakataurite i ngā whakaritenga ā-pūkaha mō te Wāhanga B i roto i te API 5L, ASTM A106, me te ASTM A53 e whakaatu ana he rite tonu ngā whakaritenga mō te kaha kume me te kaha tuku. Ko tēnei ōritetanga te pūtake mō te whakawhitiwhiti o ēnei paerewa, ā, ka whakarite kia taea te whakamahi i ngā hua ngongo i roto i te whānuitanga o ngā tono me te kore e manukanuka ki ngā āhuatanga kāore i te ōrite.
