Tirohanga Whānui mō ngā Paipa Rino Whakarewahia Porowhita API 5L:
Paerewa: API 5L
Whakaahuatanga: E whakamārama ana te API 5L i ngā whakaritenga mō te hanga i ngā taumata whakatakotoranga hua e rua (PSL1 me PSL2) o ngā paipa maitai kore hononga me ngā paipa whakarewa. Ko ngā paipa SSAW (Spiral Submerged Arc Welded) he momo paipa maitai whakarewa i hangaia mā te tikanga whakarewa porowhita, e āhei ai te hanga i ngā paipa diameter nui.
Ngā Whakatakotoranga Matua mō ngā Paipa Rino 1500MM SSAW:
Diameter:1500mm (60 inihi)
Matotoru o te Pakitara:Ka rerekē pea te matotoru o te pakitara i runga i ngā whakaritenga motuhake, engari ko ngā uara noa kei waenga i te 6mm ki te 25mm, neke atu rānei.
Te Kaupae Rino:
PSL1: Ko ngā māka noa ko A, B, X42, X46, X52, X56, X60, X65, X70.
Tukanga Hanga:
SSAW (Whakarewa Āwhata Rukuhia ki te Roto): Kei roto i tēnei tukanga te takai tonu o te rīpene maitai hurihuri-wera ki runga i tētahi mandrel hurihuri i tētahi koki kua tohua ki te tuaka paipa, ka hanga he hononga āwhata. Kātahi ka whakarewahia te hononga ki roto, ki waho hoki mā te whakamahi i te whakarewa āwhata rukuhia ki te roto.
Roa:Ko te roa e tukuna ana he 12m (40 putu), engari ka taea te tapahi kia rite ki te roa e hiahiatia ana e te kiritaki.
Te paninga me te arai:
Paninga o Waho: Kei roto pea ko te 3LPE, 3LPP, FBE, me ētahi atu momo hei tiaki i te waikura.
Arai ā-Roto: Ka taea te whakauru i te paninga epoxy hei ātete ki te waikura, te arai moata sima mō ngā paipa wai, ētahi atu arai motuhake rānei.
Ngā Momo Mutunga:
Pito Noa: He pai mō te whakarewa mara, mō te hononga miihini rānei.
Ngā Pito Whakapiko: Kua whakaritea mō te whakarewa.
Ngā tono:
Te Tuku Hinu me te Hau: He whānuitia te whakamahinga mō te kawe i te hinu me te hau māori.
Tuku Wai: He pai mō ngā kaupapa tuku wai nui.
Ngā Kaupapa Hanganga: Ka taea hoki te whakamahi i roto i ngā tono hanganga e hiahia ana he paipa whānui.
Te Whakapūmau Kounga o ngā Paipa Rino Whakarewa SSAW:
Te Kaha o te Hua:I runga i te momo, ka taea e te kaha whakaputa te awhe mai i te 245 MPa (mō te Taumata B) ki te 555 MPa (mō te Taumata X80).
Kaha Kume:I runga i te momo, ka taea e te kaha kume te awhe mai i te 415 MPa (mō te Taumata B) ki te 760 MPa (mō te Taumata X80).
Whakamātautau Waipūmau:Ka whakamātauhia ia paipa ki te wai pūmau hei whakarite i te pumau o te hononga whakarewa me te tinana o te paipa.
Tirotiro Ahu:Mā te reira ka tutuki te paipa i ngā rahi me ngā āheinga kua tohua.
