I roto i ngā kaupapa turanga pou, ko te kounga o ngā pou paipa maitai te mea e whakatau tika ana i te pumau me te pakari o te turanga whare. Te whiriwhiri i tētahi mea ponoTe Wheketere ASTM A252Ko te taahiraa tuatahi nui tēnei hei whakarite i te haumaru o te kaupapa. Mā tēnei tuhinga koe e āwhina ki te mārama ki ngā kaupapa matua o te paerewa ASTM A252 me pēhea te aromatawai i ngā kaiwhakarato kounga teitei.
Te Whakamārama i te Paerewa ASTM A252
Ko te ASTM A252 he paerewa mō ngā "pouaka paipa maitai kua whakarewaina, kua honoa hoki" i hangaia e te American Society for Testing and Materials. E pā ana tēnei paerewa ki ngā pou porowhitapuranga paipa maitaime te matotoru o te pakitara ingoa, ā, e rua ngā momo whakamahinga:
Ngā wāhanga tautoko tuturu: Ko ngā paipa rino te hanganga tautoko tuturu, e tautoko tika ana i ngā kawenga o te whare.
Anga ringihanga raima: Ko te paipa rino te anga, ā, ka ringihia te raima ki roto hei hanga i tētahi puranga whakarewa-ki-te-tūnga.
E toru ngā taumata kaha e hipokina ana e te paerewa: Tau 1, Tau 2, me Tau 3. I roto i ēnei, he tino pai te kaha ki te whakarewa me te penapena o te Paipa Rino A252 TARATA 1, ā, he pai mō ngā kaupapa turanga pou māmā ki te rahi waenga.
Ngā whakaaro matua mō te rahi o ngā puranga paipa maitai
Te kōwhiringa oNgā Rahi Paipa ASTM A252ka pā tika ki te whai huatanga o te hanganga me te kaha ki te kawe kawenga. Ko ngā tawhā matua ko:
Te whānuitanga o te diameter: E ai ki ngā āhuatanga whenua me ngā whakaritenga kawenga, ka taea te whakarite mai i ngā diameter iti ki ngā diameter tino nui.
Te matotoru o te pakitara: Ko te matotoru o te pakitara ingoa te mea e whakatau ana i te kaha pēhi me te kaha piko.
Te roa o te paipa kotahi: Te whakaiti i ngā hononga whakarewa i te papaanga, me te whakarei ake i te whai huatanga o te hanga
Ko ngā paipa puranga whakarewa i tukuna mai e Cangzhou Spiral Steel Pipe Group Co., Ltd. he whānui kei waenga i te 219mm ki te 3500mm, ā, ka taea e ia puranga te tae ki te 35 mita te roa, e tutuki ai te hiahia mō ngā puranga roa i roto i te hangarau turanga hōhonu.
Me pēhea te aromatawai i tētahi wheketere ASTM A252 kounga teitei
I te wā e whiriwhiri ana i tētahi wheketere ASTM A252, me whai whakaaro ki ēnei āhuatanga:
Ngā tohu whakaputa me te kaha whakaputa
I whakatūria te Cangzhou Spiral Steel Pipe Group i te tau 1993, ā, he kaihanga matua ia mō ngā paipa rino porowhita me te paninga paipa i Haina. Kei te Tāone o Cangzhou, Porowini o Hebei te wheketere, e 350,000 mita pūrua te rahi, ā, ko te katoa o ngā rawa he 680 miriona yuan. E 400,000 tana o ngā paipa rino porowhita e whakaputaina ana i ia tau, ā, ko te uara putanga ā-tau he 1.8 piriona yuan. Mā te kaha whakaputa pumau ka taea te tuku wawe i ngā ota nui.
2. Pūnaha Whakahaere Kounga
Kia tino tutuki i te paerewa ASTM A252. Whakatinanahia te mana whakahaere whānui puta noa i te tukanga mai i te hoko rīpene maitai ki te tirotiro whakarewa hei whakarite i ngā āhuatanga miihini me te tika o ngā rahinga o ngā rauemi paipa.
3. Te kaha ki te paninga ā-waikura
He maha ngā wā ka pāngia ngā kaupapa turanga pou e te haukū, e te waikura rānei. Mā te ratonga paninga e whakaratohia ana e te wheketere mō ngā rauemi paipa ka taea te tuku otinga ārai-waikura pērā i te epoxy me te PE, ā, ka roa ake te ora o te mahi.
4. Ngā painga o te kawe waka
Kei te taha tonu o te Tauranga o Tianjin a Cangzhou. Mā te whakamahi i te tauranga nui rawa atu i te raki, ka taea e ia te whakatutuki i te kawe waka moana-whenua whai hua, ā, ka whakaitihia ngā utu kawe waka o te ao.
Whakamutunga
I te wā e whiriwhiri ana i tētahi wheketere ASTM A252 pono, me arotake whānuitia ōna paerewa whakaputa, te kapinga whakatakotoranga, te kaha whakaputa me ngā āheinga whakahaere. Me te tata ki te 30 tau o te wheako hanga me te painga katoa o te mekameka ahumahi, e whakapau kaha ana a Cangzhou Spiral Steel Pipe Group ki te whakarato i ngā otinga puranga paipa maitai kounga teitei mō ngā kaupapa turanga puranga o te ao.
Tena koa whakapā mai ki a mātou mō ngā whakaaro whiriwhiri me ngā whakatau utu ritenga mō ngā Rahi Paipa ASTM A252.
