Ko te nuinga o te ahotea toenga o ngā paipa LSAW he mea nā te whakamatao koretake. Ko te ahotea toenga ko te ahotea taurite ā-roto me te kore he kaha o waho. Kei roto i ngā wāhanga huri wera o ngā wāhanga rerekē tēnei ahotea toenga. Ko te nui ake o te rahi o te wāhanga o te maitai wāhanga whānui, ko te nui ake o te ahotea toenga.
Ahakoa he taurite te ahotea toenga, he pānga tonu tōna ki te mahi a ngā mema maitai i raro i te kaha o waho. Hei tauira, tera pea he pānga kino ki te whakarerekētanga, te pumau me te ātete ki te ngenge. Whai muri i te whakarewa, ka pēhia ngā whakaurunga kore-whakarewa i roto i te paipa LSAW kia angiangi, ka hua ake he whakakikorua. Kātahi ka tino heke te mahi kume o te paipa LSAW i te ahunga matotoru o te whakakikorua, ā, ka pakaru pea te paparanga ina whakaitihia te whakarewa. Ko te taumahatanga ā-rohe i puta mai i te whakahekenga whakarewa he maha ngā wā o te taumahatanga pūwāhi hua, he nui ake i te mea i puta mai i te kawenga. Hei tāpiri, he maha ngā whakakikorua-T o te paipa LSAW, nō reira ka tino pai ake te tūponotanga o ngā hapa whakarewa. Hei tāpiri, he nui te ahotea toenga whakarewa i te whakakikorua-T, ā, he maha ngā wā kei roto te whakarewa whakarewa i te āhua ahotea toru-ahu, e whakanui ake ana i te tūponotanga o ngā pakaru.
Ka tohatohahia te hononga whakarewa o ngā paipa whakarewa porowhita i raro i te pewa porowhita i roto i te rārangi porowhita, ā, he roa ngā whakarewa. Ina koa i te wā e whakarewahia ana i raro i ngā āhuatanga hihiri, ka wehe te whakarewa i te pūwāhi hanga i mua i te whakamatao, ka ngāwari te hanga i ngā kapiti wera whakarewa. Ka whakarara te ahunga kapiti ki te whakarewa, ā, ka hanga he koki whakauru ki te tuaka paipa maitai, i te nuinga o te wā, ko te koki kei waenga i te 30-70°. He rite tonu tēnei koki ki te koki rahunga kutikuti, nō reira kāore ōna āhuatanga piko, kume, pēhi me te ārai-hurihuri i te pai ki te paipa LSAW. I taua wā anō, nā te herenga o te tūranga whakarewa, ka pā te hononga whakarewa nohoanga me te tuara ika ki te āhua. Nō reira, me whakapakari te NDT o ngā whakarewa paipa SSAW kia pai ai te whakarewa, ki te kore, kaua e whakamahia ngā paipa SSAW i ngā wā hanganga maitai nui.
