He mea nui te paipa maitai kore-whakarewa, e whakamahia whānuitia ana i roto i ngā mara maha. Nā te tukanga hanga ahurei, ka kore he hononga o te paipa maitai, he pai ake ngā āhuatanga miihini me te ātete ki te pēhanga, ā, he pai mō ngā taiao pēhanga teitei me te pāmahana teitei.

Mō ngā āhuatanga whakamahinga, he mea noa te whakamahi i ngā paipa rino kore hononga i roto i ngā mara pēnei i te kawe hinu me te hau, te ahumahi matū, te hanga, te hanga kaipuke me te ahumahi motuka. Ina koa i roto i te ahumahi hinu me te hau, he mea noa te whakamahi i ngā paipa rino kore hononga mō ngā paipa me ngā taputapu o raro, ā, ka taea te tu atu i ngā āhuatanga taiao kino.

Mō ngā paerewa, ko ngā paipa maitai tui kore e hangaia ana, e whakamatautauria ana hoki i runga anō i ngā paerewa ā-motu (pērā i a GB, ASTM, API, me ētahi atu).GB/T 8162e tika ana mō ngā paipa maitai kore hononga mō ngā hanganga, i te wāASTM A106e whakamahia ana mō ngā paipa maitai waro korekore mō te mahi pāmahana teitei. Mō ngā paipa maitai koranu korekore, ko ngā paerewa noa koASTM A335, ā, ko ngā māka e tohu ana ko te P5 me te P9 hei whakarite i te mahi a ngā paipa maitai i ngā pāmahana me ngā pēhanga motuhake.

Mō ngā rauemi, ko ngā paipa maitai kore-whakarewa he mea whakamahi i ngā maitai iti-whakarewa me ngā maitai teitei-whakarewa, he tino ātete ki te waikura, ki te pāmahana teitei, ki te waikura hoki. Hei tauira, ko ngā rauemi e whakamahia whānuitia ana mō ngā paipa maitai ko te maitai Cr-Mo (pēnei i te 12Cr1MoG me ētahi atu), e tika ana mō ngā taputapu pāmahana teitei me te pēhanga teitei pērā i ngā kohua me ngā whakawhiti wera. Ka tirotirohia me te tirotirohia ēnei rauemi kia mau ai te pumau me te haumaru i raro i ngā āhuatanga tino kino.

He mea nui ngā paipa maitai kore hononga, inā koa ngā paipa maitai kore hononga koranu, i roto i te ahumahi o ēnei rā. Nā te mea he paerewa te hanga me ngā rauemi pai rawa atu, he mea pai mō ngā mahi hangarau maha.
