SSAW(e mōhiotia ana hoki koSAWH) e pā ana te paipa maitai ki te paipa maitai kua whakapirihia ki te pewa i raro i te wai, he mea whakapiko porowhita kua whakapikohia.
Ko te tukanga whakaputa mō tēnei momo paipa rino ko te whakapiko tonu i ngā pereti rino kia rite ki te āhua porowhita, me te whakapiripiri i ngā taha o ngā pereti mā te whakapiripiri pewa ruku ā-roto, ā-waho hoki hei hanga i tētahi hononga whakapiri porowhita mō te paipa.
Ko te āhuatanga o tēnei momo paipa rino he hononga whakarewa porowhita, ā, nā te tino pai o te whakaputanga he pai mō te hanga paipa rino whānui.
He kaihanga me te kaiwhakarato paipa maitai whakarewa a Botop Steel nō Haina, e tuku ana i te whānuitanga o ngā paerewa me ngā rahi o ngā paipa maitai ka taea te whakarite kia tutuki ai ngā whakaritenga o tō kaupapa.
Ko ngā hua paipa maitai SSAW ka taea e mātou te tuku ko te paipa maitai porowhita o te API 5L, ASTM A252, EN 10217, GB/T 9711, me te maha atu o ngā paerewa. Hei tāpiri, he maha ngā ratonga e tukuna ana e mātou tae atu ki te tukatuka paipa maitai, te whakapuru, ngā hononga paipa, te paninga, te tango pupuhi, me te maha atu.
Ko te painga ahurei o ngā ngongo SSAW ko te kaha ki te whakaputa ngongo whānui tae atu ki te 3,500 mm, he mea kāore e taea e ētahi atu momo ngongo.
Hei tāpiritanga ki tēnei, he tere te tere o te whakaputa i ngā ngongo SSAW, he kaha ki te whakaputa i ngā ngongo roa ake, me te whānuitanga o ngā whakamahinga.
He tukanga tino aunoa te hanga paipa maitai SSAW, e kore e whakapai ake i te whai huatanga o te hanga paipa maitai anake, engari e whakarite ana hoki i te paerewa kounga teitei o te hua.
Ka kiia te SSAW i ētahi wā koDSAWnā te mea ka whakamahia te hangarau whakarewa pewa ruku rua-taha mō te whakarewanga whakarewa.
