Paipa LSAW (Whakarewa Āwhata Roa)
LSAW (Whakarewa Āwhata Ruku Roa):E pā ana tēnei ki te tukanga hangahanga.
Roa: Ka rere whakarara te hononga whakarewa ki te roa o te paipa (i roto i te rārangi tika). He rerekē tēnei i te HSAW/SSAW (Helical/Spiral Submerged Arc Welding), arā, he porowhita te whakarewa.
Te Whakarewa Āwhata Ruku (SAW): He tukanga whakarewa kounga teitei e rumakina ai te āwhata ki raro i tētahi paparanga o te rerenga wairewa. Mā tēnei ka taea te uru hohonu o te wera, ka hangaia he whakarewa tino kaha, ōrite, ā, ka puta he āhua maeneene me te kore e tauhiuhi.
Tuitui Tika, Taha-Rua:E whakaahua ana tēnei i te āhuatanga ā-tinana o te whakarewa.
He mea hanga te paipa mai i tētahi pereti maitai kotahi (skelp) kua hurihia hei rango, ka hanga he hononga tika kotahi.
Taha-Rua: Ka mahia te whakarewa i roto, i waho hoki o te paipa. He mea nui tēnei kia tino tika ai te whakarewa, kia taea ai te whakahaere i ngā pēhanga teitei me ngā mahi uaua.

Ngā Whakamahinga Matua o ngā Paipa Rino LSAW
| Kāwai Taupānga | Ngā Whakamahinga Motuhake | He aha i whakamahia ai te LSAW |
| Ngā Paipa Hinu me te Hau o Tāmaki Makaurau/O Tāwāhi | Ngā paipa tuku mō te hinu mata, te hau māori, me ngā hua kua whakapaia. | Ka taea te tu atu i ngā pēhanga ā-roto tino tiketike, ka ātete ki ngā ahotea o waho, ā, ka taea te pani hei ārai i te waikura i roto i ngā taiao uaua. |
| Ngā Ratonga Pēhanga Teitei | Te mamaoa pēhanga teitei, ngā raina whāngai matū, me te kawe paru. | Ka taea e te hanganga pakari te tu atu i te ahotea pumau, kino, me te kore e pakaru. |
| Ngā Hanganga Moana me ngā Hanganga Pou | Te whakatū pou turanga mō ngā piriti, ngā tauranga, me ngā papaaho tai. | Nā te whānui me te matotoru o ngā pakitara, he nui te tautoko hanganga me te kaha ki te pikau i ngā kawenga. He maha ngā wā ka peia ki roto i te whenua. |
| Hangarau Ā-iwi me te Hanganga | Ngā pou hanganga mō ngā whare teitei, ngā papa tākaro, me ngā whare nunui. | E whakamahia ana hei "pou paipa" kua whakakīia ki te raima (CFST) hei whakarato i te kaha me te pumau whakamiharo ki te hanganga matua. |
| Te Tuku Wai | Ngā paipa wai me ngā paipa wai whānui mō ngā tipu hiko wai. | Ka taea te neke i ngā rahinga wai nui i raro i te pēhanga teitei. |

Kua hangaia e mātou he pūnaha whai i ia paipa mai i te pereti ki te paipa kua oti te hanga me te tau o ngā paipa, ā, hei pupuri i te rekoata mō te iti rawa i te rua tau.
He aha i whiriwhiria ai ngā paipa LSAW mō ngā tono teitei
Te Whakatauranga Kaha me te Pēhanga Pai Rawa:Mā te tukanga SAW taha-rua ka hangaia he whakarewa e rite ana te kaha ki te maitai turanga tonu, e kaha ake rānei i a ia. Nā tēnei ka tino pai mō ngā mahi pēhanga teitei.
Ngā Diameter Nui me ngā Pakitara Matotoru:Ka taea te hanga paipa LSAW i ngā diameter tino nui (mai i te 16 inihi ki te 60 inihi, neke atu rānei) me ngā pakitara matotoru rawa, kāore e taea tēnei me ngā tukanga paipa iti ake pēnei i te ERW (Electric Resistance Welding).
Te Tika Tino Pai o te Ahu:He tino ōrite ngā āhua me te porowhita, he mea nui tēnei mō te hanganga paipa me ngā kaupapa hanganga.
He mea pai mō ngā paninga:Nā te hononga tika me te mata maeneene, he tino pai mō te paninga i ngā momo paninga tiaki (pēnei i te FBE Fusion Bonded Epoxy, 3LPE/3LPP) me ngā arai (hei tauira, te paninga taumaha raima mō ngā paipa moana). Mā te mata maeneene, ōrite ka piri pai te paninga, ā, ka mahi i tana mahi tiaki.
