Ngā Pūrongo - Paipa LSAW me SSAW: Ngā Whakatakotoranga, Ngā Rerekētanga Matua me te Aratohu Hoko

I roto i te tuku hiko o te ao, ngā hanganga ā-tāone me ngā hanganga ahumahi taumaha, ko ngā paipa maitai whakarewa pewa raro (SAW) te pou tuara o ngā pūnaha kawe wai pono. E rua o ngā raina hua e tino tohua whānuitia ana koLSAW (Whakapirihia te Pewa Ruku Roa)meSSAW (Whakapiripiri Porowhita Rukuhia)ngā paipa. Ahakoa e whakamahia ana e rāua te pono o te hangarau whakarewa pewa i raro i te wai, ko ō rāua rerekētanga taketake i roto i te tikanga hanga me te aronga whakarewa ka waihanga i ngā āputa motuhake i roto i te mahi miihini, te whakahaere i ngā āhuatanga, te ātete ki ngā hapa, te kōtaha utu me ngā horopaki tono e tika ana. Mō ngā tohunga hoko, ngā miihini paipa me ngā kaiwhakawhanake kaupapa, he mea nui te māramatanga mārama ki ēnei rerekētanga hei whiriwhiri i te hua tino pai e hangai ana ki ngā tikanga whakahaere, ngā whakaritenga ture me ngā utu huringa ora katoa.

Ngā Whakatakotoranga Paipa LSAW me SSAW, Ngā Rerekētanga Matua me te Aratohu Hoko

He aha te paipa LSAW?

Paipa maitai LSAW, he whakarāpopototanga mō te paipa whakarewa porowhita roa, e kiia ana hoki koPaipa SAWL, he mea hanga mai i ngā pereti maitai taumaha motuhake. Ko te nuinga o ngā mahi hanga arumoni e whai ana i te ara hanga JCOE: ka huri tuatahi ngā pereti mata ki te mira taha tika, kātahi ka hangaia mārire kia rite ki te kōtaha porotaka mā roto i ngā wāhanga hanga-J, hanga-C me te hanga-O, i mua i te whiwhi i te whakarewa pewa ruku rua-taha o roto me waho. Ko te whakaotinga i muri i te whakarewa ko te rahi, te whakatikatika miihini, te whakapiko pito me te manatoko kounga raina-katoa.

Mā tēnei hoahoa hononga-tika, he pereti te turanga, ka puta he painga ā-roto mō te ōritetanga o te whakarewa, te ōritetanga o te āhuatanga miihini me te pono o te hanganga. Ka rere whakarara te hononga whakarewa ki te tuaka paipa, me te poto o te roa whakarewa katoa mō ia wāhanga paipa pumau, e whakaiti ana i te mōrearea tatauranga o ngā hapa whakarewa.

Paipa LSAWNgā Whakatakotoranga me te Mahi

Awhe whānui o waho:Ko te whānuitanga o te hanga paerewa mai i te 16 inihi (406 mm) ki te 60 inihi (1,524 mm), me te rahi ritenga e wātea ana mō ngā kaupapa hangarau motuhake.

Te kaha o te matotoru o te pakitara:Tautoko ana i te hanga pakitara taumaha kia tutuki ai ngā whakaritenga kaha-teitei, pēhanga-teitei, me ngā rohe matotoru e nui ake ana i ērā o ngā momo ERW me ngā momo whakarewa porowhita.

Ngā kaha matua o te mahi:He ātete pai rawa atu ki te pēhanga o roto, he pakari pai rawa atu i te pāmahana iti, he ātete ki te porowhita me te tika, ā, he pūmau pono te turuturu i raro i te kawenga huringa.

Ngā Whakamahinga Matua o te Paipa LSAW

Ko te paipa LSAW te paerewa ahumahi mō ngā raina matua tuku hinu me te hau, inā koa ko ngā huarahi roa e whiti ana i ngā tāone nui taupori, ngā awa o uta, ngā taiao moana me ngā rohe tiaki taiao. E ai ki ngā whakaritenga hoahoa paipa API 5L, kua whakaaetia katoatia mō ngā akomanga wāhi Akomanga 1 me te Akomanga 2 kei reira te haumaru tūmatanui me te pono o te mahi e kore e taea te whiriwhiri.

Haunga te rāngai pūngao, he whānuitia te whakamahinga mō ngā hanganga taumaha me ngā ratonga, tae atu ki te whakatū pou piriti kawenga, ngā puna tuku wai nui, ngā paipa tukatuka tipu hiko wera me ngā pūnaha ahumahi e hiahia ana ki te kaha hanganga teitei me te roa o te ora ratonga.

He aha te paipa SSAW?

Paipa SSAW, he paipa whakarewa porowhita-uru-ki-te-raro rānei – e mōhiotia ana koPaipa HSAW (Helical Submerged Arc Welded)– ka hangaia mā te tukanga hanga whāngai-koiri tonu. Ka whāngaihia he rīpene maitai hurihuri-wera ki roto i te mira hanga i te koki porowhita e whakahaeretia ana, ka hurihuri hei āhua porotaka, i te wā e whakarewahia ana te hononga porowhita i runga i ngā mata o roto me waho mā te whakarewa pewa ruku.

Ko tētahi painga ōhanga matua o tēnei tukanga ko tōna ngāwari ki te whakaputa: ka taea te hanga i tētahi whānui kotahi o te rīpene maitai hei paipa o ngā diameter o waho maha mā te whakarerekē noa i te koki hanga. Ka whakapai ake tēnei i te whakamahinga rauemi whānui, ka whakaiti hoki i ngā utu whakawhiti taputapu mō ngā ota diameter nui, rahinga nui.

Paipa Rino SSAWNgā Whakatakotoranga me ngā Āhuatanga

Te whānuitanga o te diameter o waho: Ko te putanga paerewa e kapi ana i te 20 inihi (508 mm) tae atu ki te 100 inihi (2,540 mm), e mahi ana i te whānuitanga o ngā tono poka nui.

Ngā āhuatanga hoahoa: Ka tohatohahia e te hononga porowhita te ahotea mahi puta noa i te hononga koki, ka whakaitihia te kawenga ahotea noa e poutū ana ki te rārangi hononga i raro i te pēhanga ā-roto. Heoi, he roa ake te roa katoa o te hononga hononga i tērā o te paipa LSAW ōrite, ka whakanui ake i te tūponotanga tatauranga o ngā hapa hononga.

Ngā whakaaro kounga: Ko ngā wero hanga noa i roto i te whakarewa porowhita ko te porowhita, ngā whakaurunga para, te hanumitanga kāore i oti me te tohatoha ahotea toenga kore taurite, e hiahia ana kia whakamātautau whānuitia te kore-whakangaro (NDT) puta noa i te roanga whakarewa katoa hei manatoko i te tutuki.

Ngā Whakamahinga Matua o ngā Paipa SSAW

I roto i ngā pūnaha hinu me te hau, ko ngā paipa SSAW te mea matua mō ngā wāhi Akomanga 3 me te Akomanga 4 e ai ki ngā paerewa API, tae atu ki ngā raina kohikohi mara, ngā whatunga tohatoha rohe me ngā huarahi tuku pēhanga iti. He hua matua hoki tēnei i roto i ngā kaupapa miihini ā-tāone me ngā kaupapa hangarau ā-iwi, pērā i te tuku wai inu, te waikeri wai ua me te waipara, ngā paipa whakamahana rohe, me te pou turanga mō ngā whare me ngā hanganga tauranga. Mō ngā tono pēhanga ngawari, kāore i te tino nui, ka tukuna he taurite kaha o te mahi hanganga me te whai huatanga utu.

Ngā Rerekētanga Matua i waenga i ngā Paipa LSAW me SSAW

Mā te whakatairite taha-ki-taha ka āwhina i te whakataurite i te kōwhiringa hua ki ngā kaupapa matua o te kaupapa:

Kounga Whakarewa me te Mōrearea o te Koha

He poto, he tika, he roa hoki te hononga o ngā paipa LSAW, he iti ake ngā taurangi hanga, ā, ka hua ake he hanganga whakarewa tino ōrite, he iti ake hoki ngā reiti hapa ā-roto. He roa ake te hononga porowhita o ngā paipa SSAW, ā, he nui ake ngā tawhā tukanga e hono ana hei whakahaere, ka nui ake te tūponotanga taketake o ngā hapa pēnei i ngā whakaurunga me te hanumitanga kāore i oti.

Te Kaha Whakapūmau Pēhanga

Nā te pai o te hanganga whakarewa me te matotoru o te pakitara, ka nui ake te pēhanga pakū o ngā paipa LSAW me te ātete roa ki te ngenge, ā, he pai mō te mahi pēhanga teitei, mahi taumaha. Ahakoa ka whakaitihia e te hononga porowhita koki te kukū o te ahotea ki runga i te whakarewa tonu, ko te whakatauranga pēhanga whānui o ngā paipa SSAW ka herea e te ōritetanga kounga whakarewa me ngā rohe matotoru o te pakitara.

Te Tika o te Ahu

Ko ngā paipa LSAW i hangaia mai i ngā pereti maitai tapahi-tika, he kaha ake te āheinga ki te whānui o waho, te porowhita me te tika, e māmā ake ai te whakauru me te whakarite hononga i te papaanga. He whānui ake ngā āheinga ā-ahu o ngā paipa SSAW i hangaia mā te hanga koiri tonu, ka taea te whakanui ake i te mahi tāutanga me te wā whakatikatika i runga i ngā kaupapa nui.

Ōhanga Whakaputa

He tukanga whakaputa nui tonu te hanga SSAW me te whakamahinga rauemi nui ake, e hoatu ana he painga utu mārama ki ngā ota pakitara nui te whānui, waenga. He maha ake ngā mahi hanga me te whakaoti motuhake mō te hanga LSAW, ka hua ake he utu wāhanga teitei ake engari he kounga me te mahi tino pai, e taea te matapae.

Te Whakaaetanga Whakahaere me te Kaiwhakahaere

E whakaaetia whānuitia ana ngā paipa LSAW e ngā waehere paipa nui me ngā kaiwhakahaere hinu me te hau o te ao mō ngā ara paipa tino nui, tino haumaru hoki. He whaiti ake te whakaaetia o ngā paipa SSAW mō ngā tono raina matua pēhanga teitei, ā, e whakaaetia ana mō ngā akomanga wāhi iti te mōrearea me ngā hanganga kore-pūngao.

Me pēhea te whiriwhiri i te momo paipa tika

Kāore he hua "pai" whānui - ko te kōwhiringa tino pai e whakawhirinaki ana ki te aromatawai whānui o ngā tawhā motuhake mō te kaupapa:

Tīpakohia te paipa LSAW mēnā:Kei roto i tō kaupapa te tuku hiko pehanga teitei i tawhiti, ka whakahaerehia i roto i ngā taiao pāmahana iti, ka whiti i ngā rohe taupori Akomanga 1/2, ngā rohe tairongo taiao rānei, ka hiahiatia rānei te pono mō te wā roa me te iti o te mōrearea tiaki.

Tīpakohia te paipa SSAW mēnā:Me whai paipa nui te whānui mō ngā tono pēhanga iti ki te waenga, kei roto hoki i te tahua pūtea iti, ā, kei raro te kaupapa i ngā wāhi Akomanga 3/4, i ngā whakamahinga ā-tāone/hanganga rānei, he kaupapa matua te arotau i te utu.
