Ko te tukanga hanga moA252 Grade 3 paipa maitaiko te hanga i te paihere torino haere tonu i te roa o te paipa, ka puta he hanganga pakari, korekore.Ko tenei tikanga hanga ka whakanui ake i te kaha o te putorino ki te tohatoha i te ahotea me te aukati i te whakarereketanga, he pai mo nga whakaurunga o raro.I tua atu, ka whakakikoruatia te paipa ki te whakamarumaru whakamarumaru e whakanui ake ana i tana aukati ki te pirau me te kakahu, me te whakarite i te roa o te ratonga i roto i nga tono paraka.

Ko te paipa rino A252 Grade 3 kua hangaia hei whakatutuki i nga whakaritenga motuhake o te hanga paipa parakaingaki, penei i te whakarato i te awa pono mo te wai para me te parakaingaki, me te mau i te whenua me nga kawenga waka kei runga ake.Ko nga ahuatanga kaha o nga paipa rino ka taea e ratou te pupuri i te tika o te hanganga ahakoa i raro i nga ahuatanga uaua, na reira ka whakaiti i te tupono o te pakaru, te tiango me etahi atu momo ngoikoretanga o te hanganga.

I tua atu i ona taonga miihini, ko te paipa rino A252 Grade 3 he pai te utu mo nga kaupapa parakani.He ngawari ki te whakauru, he iti nga whakaritenga tiaki me te roa o te ratonga, e awhina ana ki te whakaora i nga utu katoa mo te oranga o te hanganga.I tua atu, ko te hototahi o te paipa me nga momo momo hononga me nga taputapu ka taea te hanga ngawari me te whai hua e tutuki ana i nga hiahia motuhake o te kupenga parapara.

Ka whai hua nga Kaikirimana raima me nga kamupene miihini mai i nga mahi pai ake o te paipa rino A252 Grade 3 i roto i a raatau kaupapa na te mea he otinga pono me te wa roa mo te kawe wai para i raro i te whenua.Ma te kowhiri i nga rauemi kounga penei i te paipa rino A252 Grade 3, ka taea e ratou te whakarite i te mahi mo te wa roa me te kaha o o raatau punaha parakaingi, me te whakaiti i te tupono o te utu utu me te aukati ratonga.

Hei whakarāpopototanga, ko te paipa maitai A252 kōeke 3 he pai te kaha o te kaha, te aukati waikura, me te utu utu nui, na te mea he pai rawa atu mo te hanga paipa waipara.Ko tana hanganga maamaa me te pakari, me te rite ki nga whakaritenga paipa API 5L, ka waiho hei otinga pono me te roa mo te kawe wai para i raro i te whenua.Ka taea e A252 Grade 3 te paipa rino te tu ki nga ahuatanga o raro o te whenua me te whakarato mahi mo te wa roa, ka waiho hei rauemi maataki mo nga kaupapa hanganga parakaingi.
