I te ao whakataetae o te hokohoko maitai B2B, ko te whiriwhiri i waenga i te ASTM A53 Grade Ame te Taumata Behara i te mea he mahi hangarau noa iho—he whakatau e pā ana ki ngā tawhā haumaru o tō kaupapa me te utu taunga katoa. Hei kaihanga matua iTianjinE te Yuantai Derun Group, kua kite mātou me pēhea te hapa iti i ngā whakaritenga e arahi ai ki ngā hapa whakahaere utu nui.
Kati te Matapae: He aha te Hiranga o te Tātaitanga Wā-Tūturu
Ko tētahi o ngā "kaipatu tahua" nui rawa atu i roto i te hokohoko o te ao ko te whakatau tata i te taumaha. He maha ngā āpiha hoko e whakawhirinaki ana ki ngā tūtohi ariā, engari ina whakaarohia te nekehanga mai i te SCH 40 ki te SCH 80, ka taea e te papatipu te peke tata ki te 50% (hei tauira, ka neke te paipa NPS 6 inihi mai i te ~28.26 kg/m ki te ~42.56 kg/m).
Ehara i te mea ko te maitai anake te mea e pā ana ki tēnei; engari ko tō utanga moana me te kaha o te kerēni. Hei whakaoti i tēnei, kua whakauruhia e mātou he Kaiwhakamana Tautuhinga Ora me te Taumaha i raro nei. Kāore i rite ki ngā ripanga tūmau, ka tohu tēnei taputapu i ngā pakanga hanga pea—pērā i te wā he tino nui rawa te matotoru o te pakitara e tonoa ana mō ngā tukanga ERW paerewa.
Te Tuarā Mīhini: He aha mātou i tūtohu ai i te Taumata B
Ahakoa e whakahuatia pinepinetia ana te Wāhanga A mō ōna āhuatanga pai ki te piko makariri, ko te ASTM A53 Wāhanga B tonu te "hōiho mahi" o te umanga. Anei te take:
Huanga Nui Ake, Hanganga Haumaru Ake:Kaua e petipeti ki te rohe 205 MPa o te Taumata A. Ka whakanuia e te ASTM A53 Taumata B te kaha whakaputa ki te 240 MPa. Ehara i te mea he tau noa iho taua kaha tāpiri 17%—ko te rerekētanga i waenga i tētahi kaupapa kāore i te eke ki te taumata tika me tētahi i hangaia mō ngā hanganga mahi taumaha me ngā raina wai pēhanga teitei.
Te Hanga e rite ana ki tāu Tahua:He tino ngāwari te whakamahi i te Paerewa B puta noa i ngā momo raina hangahanga. Mena kei te rapu koe ki te penapena utu, koinei te paerewa mō ngā paipa ERW. Mena kei te hiahia koe ki te pono mō ngā taiao taumahatanga nui, ka tino pai tana mahi hei Tuitui Tngā ubeKa pā ki te "wāhi reka" onge, kāore koe e hiahia ki te whakarērea i te ngāwari mō te kaha.
Kei tua atu i te Whakarewa: Hangarau Paninga Matatau
Mena kei te takutai moana tō kaupapa he nui te tote, he nui rānei te pānga o ngā matū waikura, kāore pea e ranea te tiaki mā te whakamahi i te whakapūmau wera. Koinei te wāhi ka taea e ngā paninga Zinc-Magnesium-Aluminium a Yuantai Derun te tuku i tētahi otinga pono ake. Ka tukuna e tēnei hangarau "Whakaora-Whaiaro" te ātete ki te waikura tae atu ki te 10 ngā wā o ngā tikanga tuku iho, ka tino whakaiti i ō huringa tiaki mō te wā roa.
Tikina he Tāpaetanga Pono i roto i ngā hēkona
Me nui atu i ngā rahi paerewa anake?Me hiahia koe ki te whakahaere tika i te koki-R, ki te SHS/RHS rānei kia rite ki te roa? Kei te rite tā mātou tīma hangarau ki te tautoko i a koe. I Yuantai Derun, ehara i te mea ko ngā paipa anake tā mātou e tuku ana — engari ka whakaratohia e mātou ngā otinga hanganga kua hangaia kia roa.
