Ngā Pūrongo - Paipa API Tuitui me te Paipa API Whakarewa: He Whakataurite Whānui mō ngā Kaihanga Kaupapa

I roto i ngā kaupapa hanganga mōrearea nui pērā i ngā papa keri hinu ki tai, ngā tipu matū, ngā paipa hau pēhanga teitei rānei o te tāone, ko ngā paipa te kaupapa matua. Mō tePaipa maitai API 5LKo te tikanga, ko te tautohetohe e aro ana ki ngā kōwhiringa matua e rua:paipa maitai kore-tuituimepaipa maitai whakarewa(ERW/LSAW).

Ehara i te mea he take tahua anake te whiriwhiri i te paipa hē, engari he take haumaru me te roa o te ora hoki. Kei raro nei he aratohu whānui hei āwhina i a koe ki te kimi i te paipa tika mō tō tono.

Te Mārama ki te Āputa Hanga

Ko te rerekētanga matua i waenga i ngā paipa maitai kore hononga me ngā paipa maitai whakarewa kei roto i ā rātou tukanga whakaputa.

Ngā Paipa Rino Kore-Tuitui (SMLS)

Ka hangaia ngā paipa maitai kore-tui mā te keri i ngā kōhao i roto i te porowhita maitai totoka mā te whakamahi i te tukanga miihini mandrel. Nā te mea kāore he whakarewa, he ōrite te porowhita o te paipa.

Ngā Painga:He ātete pēhanga teitei, he pono teitei, he ōritetanga āhuahanga pai (he porowhita teitei).

Ngā ngoikoretangaHe nui te utu whakaputa, he roa te wā tuku mō ngā paipa nunui.

Ngā Paipa Rino Whakarewa (ERW, LSAW, SSAW)

He mea hanga ngā paipa rino kua whakarewahia mai i ngā poro rino, ngā koiri, ngā pereti rānei. Ka hurihia te poro ki roto i te paipa, kātahi ka whakarewahia mā te whakamahi i te whakarewa ātete auau-teitei (ERW) te whakarewa pewa ruku rānei (LSAW).

Ngā Painga:He tino whai hua te utu, e wātea ana i ngā diameter nui, ā, he ōrite te matotoru o te pakitara (ngā ātete).

Ngā ngoikoretanga:Kua whakaarohia tonutia te hononga whakarewa he "ngoikoretanga," ahakoa kua tino whakaitihia tēnei tirohanga e ngā whakamātautau o ēnei rā.

Te Pēhanga me te Pāmahana: Ngā Wāhi Pakaru

Ko ngā āhuatanga whakahaere te mea nui rawa atu hei whakaaroaro māu i roto i tāu whakatau kaupapa.

Ngā tono pēhanga tino teitei:Ko ngā ngongo tuikore te paerewa mō ngā tono pēhanga tino teitei. Nā te mea kāore he hononga whakaroa, kāore he mōrearea o te "rahunga o te hononga."Mena kei runga ake i te 2,000 PSI te pēhanga e hiahiatia ana e tō tono, ko ngā ngongo tui kore te kōwhiringa pai ake.

Ngā taiao waikawa/waikura:I roto i ngā taiao waikawa (kei roto te hauwai whanariki), ka ngawari ake te pakaru o ngā ngongo whakarewa ki te pakaru waikura ahotea (SCC). Ahakoa ka rongoatia ngā ngongo whakarewa kounga teitei ki ngā maimoatanga motuhake hei ātete i tēnei waikura,ngongo tuituihe painga taiao tōna i roto i te ōritetanga matū, nō reira he ātete ake.

Paipa API 5L He Paipa Tino Hira mō te Waka Pūngao

He mea nui te rahi me te tauine

Tērā pea ka taea te whiriwhiri i runga i te whānui o waho (OD) e hiahiatia ana.

Momo Paipa	Awhe Rahi Noa	Te Whakamahinga Pai rawa atu
Tuitui kore	1/8" ki te 26"	Ngā aho pēhanga teitei, he whānui iti ki te waenga.
Whakarewahia (ERW)	2" ki te 24"	Te pēhanga iti ki te pēhanga waenga, te kawe waka tawhiti.
Whakarewahia (LSAW)	16" ki te 60"+	He tuku hiko nui, he pou hanganga.

Ki te hiahia koe i tētahi48-inihipaipa matua mō te paipa hau whakawhiti-whenua, kāore e taea te hanga i taua rahi. Ka piki ake koe ki teKo te paipa LSAW (Longitudinal Submerged Arc Welded) ko te paipa SSAW (Spiral) rānei.

Te Tātari Utu-Painga

I ngā utu o nāianei,he tata ki te 20% ki te 30% te iti ake o te utu mō ngā paipa whakarewa i te paipa maitai kore hononga o te rahi me te kounga ōrite.

Āhea hei tiaki:Mena me kawe wai koe, me kohikohi hinu me te hau pēhanga iti, me whakamahi noa rānei i ngā paipa hanganga, ko te paipa whakarewa te kōwhiringa tino whai hua.

Āhea te wā hei haumi atu:I roto i ngā pūnaha e pā ana ki te ora, ki te mate rānei, i ngā paipa tipu hiko, i ngā wāhi wera rānei i roto i ngā whare whakapai hinu, he rite te utu tāpiri mō ngā paipa tui kore ki te inihua mō te pakaru kino.

Ngā Paerewa Kounga: Te Tauwehe API 5L

Kāore e pāngia te tuku o ngā māka (ahakoa he rerekē ngā māka PSL1 me PSL2). Me tutuki i te maitai tuitui me te maitai whakarewa teAPI 5L PSL1 PSL2ngā tohu whakatakotoranga hua.

PSL1: Kounga paerewa mō ngā tono whānui.

PSL2: Ngā whakaritenga tino pakari ake mō te hanganga matū, te pakari o te kokoru, me ngā āhuatanga miihini. Ko te nuinga o ngā kaupapa taiwhenua me ngā kaupapa pēhanga teitei e whakahau ana kia whakamahia te maitai PSL2 kore hononga.

Whakatau Whakamutunga: Ko tēhea te mea me whiriwhiri e koe?

Kōwhiringa Paipa Rino Kore-Tuitui:Mena kei roto koe i ngā taiao he nui te pēhanga hau, he nui te pāmahana o te mamaoa, he moana hohonu rānei, e kore e taea te whakatika mēnā ka pakaru.

Kōwhiringa Paipa Rino Whakarewahia:Mena kei te mahi koe i tētahi kaupapa nui e hiahia ana ki te pēhanga reo-waenga, me hiahia koe ki ngā paipa he nui ake i te 24 inihi te whānui, he iti rānei te tahua whakapaunga whakapaipai.

Tohutohu Ngaio:I mua i te whakaoti i tō rārangi hoko, kōrero ki tētahi miihini kaupapa ngaio, ki tētahi kaiwhakarato wheako rānei, hei arotake i ō "tawhā hoahoa". Me tino kaha ngā paipa tika, engari me whakarite hoki kia haumaru, kia iti hoki te utu.

Tāuruhia ngā whakaritenga mō tō kaupapa kia mōhio ai koe ki ngā taipitopito me ngā whakaaro mō tō kaupapa.
