Paipa LSAWKa whakamahia te hangarau whakarewa pewa ruku, mā te whakamahi i te whakarewa whakakī, te pewa huna rerenga tiaki matūriki.
Ko te LSAW te whakarāpopototanga Ingarihi mō te paipa maitai tuitui tika kua whakapikohia ki raro i te pewa. Ko te tukanga whakaputa o te paipa maitai tuitui tika kua whakapikohia ki raro i te pewa kei roto ko te hangarau hanga JCOE, te hangarau whakapiko pewa kua whakapikohia ki raro i te pewa me te hangarau hanga UOE.
Ko te tukanga hanga i te paipa LSAW (Rongonui Ruku-ā-Arc Welded Paipa) e whai ake nei:
Te whakamātautau pereti ultrasonic → te mira taha → te piko-mua → te hanga → Te whakarewa-mua → Te whakarewa ā-roto → Te whakarewa ā-waho → Te tirotiro ultrasonic → Te tirotiro hihi-X → Te whakawhanui → te whakamātautau waipēhi → te whakakoi l. → Te tirotiro ultrasonic → Te tirotiro hihi-X → te tirotiro matūriki aukume i te pito ngongo

Whakamātautau Waipūmau
Whakamātautau NDT(RT)
Whakamātautau NDT(UT)
Whakamātautau Piko—Me tū te paipa kia rawaka te roa ina pikohia mā te 90° huri noa i te pou whakarara porotaka.
Whakamātautau whakatārewatanga-Ahakoa kāore e hiahiatia he whakamātautau, me kaha te paipa ki te whakatutuki i ngā whakaritenga whakamātautau whakatārewatanga.
Whakamātautau wai-pūmau—haunga ngā mea e whakaaetia ana, me whakamātau te wai-pūmau o ia roa o te paipa, kia kore ai e turuturu mā te pakitara o te paipa.
Whakamātautau hiko kore-whakangaroHei huarahi kē atu ki te whakamātautau wai-pūmau, me whakamātautau te tinana katoa o ia paipa ki te whakamātautau hiko kore-whakangaro. Ki te whakahaerehia he whakamātautau hiko kore-whakangaro, me tohu te roa ki ngā reta "NDE".

| Diameter o Waho | Kaua te whānui o waho o ngā puranga paipa e neke atu i te ±1% mai i te whānui o waho kua tohua. | ||
| Te matotoru o te pakitara | Kaua te matotoru o te pakitara i tētahi wāhi e neke atu i te 12.5% i raro i te matotoru pakitara kua tohua. | ||
| Ngā roa | Me whakarato ngā puranga paipa i roto i ngā roa matapōkere takitahi, ngā roa matapōkere takirua, ngā roa ōrite rānei e ai ki te ota hoko, e ai ki ngā rohe e whai ake nei: | Ngā roa matapōkere takitahi | 16 ki te 25 putu (4.88 ki te 7.62mm), inihi |
| Ngā roa matapōkere takirua | Neke atu i te 25 putu (7.62m) me te toharite iti rawa o te 35 putu (10.67m) | ||
| Ngā roa ōrite | te roa e ai ki te tohu me te rerekētanga e whakaaetia ana o te ±1 inihi. | ||
| Taumaha | Me paunatia motuhake ia roa o te puranga paipa, kaua hoki tōna taumaha e neke atu i te 15% neke atu, i te 5% rānei i raro iho i tōna taumaha matapae, e tatauhia ana mā te whakamahi i tōna roa me tōna taumaha mō ia wae roa. | ||
