I roto i te ao hanga me ngā mahi ahumahi e whanake tonu ana, ko te hiahia mō ngā rauemi kaha me te pono te mea nui rawa atu. I roto i ēnei rauemi, ko ngā paipa takirua kua whakarewahia, inā koa ko ērā e tutuki ana i ngā paerewa ASTM A252, kua noho hei pou tokomanawa i roto i ngā momo mara. Ka tūhuratia e tēnei tuhinga ngā whakamahinga o ngā paipa takirua kua whakarewahia i roto i ngā mahi hanga me ngā mahi ahumahi hou, me te whakaatu i tō rātou hiranga me ō rātou painga.
Paipa takirua kua whakarewaina, e mōhiotia ana ko te paipa DSAW (whakapiripiri arc rua), ka taea te tu atu i ngā pēhanga teitei, ā, he pai mō ngā momo taiao uaua. Ko te paerewa ASTM A252 e whakahaere ana i te hanga o ēnei paipa kua whakawhirinakihia e ngā miihini me ngā tohunga hanga mō ngā tau maha. Mā te paerewa ka whakarite kia tutuki i ngā paipa ngā paerewa kounga me te mahi tino pakari, kia pai ai mō te hanga, te hinu me te hau, me ētahi atu tono ahumahi taumaha.
Ko tētahi o ngā whakamahinga matua o ngā paipa whakarewa takirua ko te hanganga o ngā anga hanganga. Nā te kaha me te pakari e hiahiatia ana hei tautoko i ngā kawenga taumaha, he mea nui ēnei paipa i roto i te hanganga o ngā piriti, ngā whare, me ētahi atu kaupapa hanganga. Nā tō rātou kaha ki te tu atu i ngā pēhanga teitei, he pai hoki mō te whakamahi i roto i ngā mahi poupou, ina panaia ki te whenua hei tautoko i te turanga.
I roto i te umanga hinu me te hau,Ngā paipa DSAWHe mea nui te mahi a te paipa DSAW i roto i te kawe i ngā wai me ngā hau. Nā tōna hanganga pakari ka taea te tu atu i ngā pēhanga teitei e pā ana ki ēnei rauemi, kia haumaru ai, kia whai hua ai hoki te kawe. Hei tāpiri, ko te ātete ki te waikura o te paipa DSAW he mea pai mō ngā taiao uaua, pērā i ngā papa keri me ngā whare whakapai hinu i waho o te moana, he mea nui te pānga ki ngā matū waikura.
He mahi uaua te hanga paipa whakapiri takirua e hiahia ana ki te tika me te tohungatanga. Kei te Tāone o Cangzhou, Porowini o Hebei, tō mātou wheketere, ā, kei mua tonu i te umanga mai i tōna whakatūnga i te tau 1993. E 350,000 mita pūrua te rahi o te wheketere, e 680 miriona RMB te tapeke o ngā rawa, ā, he hangarau hou me te 680 ngā kaimahi mohio. Mā tēnei ka taea e mātou te whakaputa paipa hau DSAW kounga teitei e tutuki ai ngā whakaritenga pakari o ngā mahi hanga hou me ngā mahi ahumahi.
Hei tāpiritanga, ko te maha o ngā whakamahinga o ngā paipa whakapiri rua kei tua atu i ō rātou whakamahinga tuku iho. Kei te piki haere te whakamahinga o ēnei i roto i ngā kaupapa pūngao hou, pērā i ngā pāmu hau me te pūngao rā, hei tautoko hanganga me ngā awa tuku pūngao. I a te ao e anga whakamua ana ki ngā otinga pūngao pumau, kāore e taea te whakanui ake i te mahi a ngā paipa whakapiri rua ki te whakahaere i tēnei whakawhiti.
Hei whakamutunga, ko ngā tono a DoublePaipa WhakarewaHe whānui, he rerekē hoki ngā āhuatanga o te hanga hou me te ahumahi. E tutuki ana i a rātou ngā paerewa ASTM A252, e whakarite ana kia tutukihia ngā paerewa kounga me te mahi teitei rawa atu, ā, he whiringa pono tēnei mā ngā miihini me ngā tohunga hanga. I te whanaketanga tonu o te ahumahi me te aro atu ki ngā wero hou, ka piki haere te hiranga o ngā rauemi pono pēnei i te Paipa Whakarewa Takirua. Nā tō mātou whakapau kaha ki te whakaputa paipa hau DSAW kounga teitei i hanga mātou hei kaiārahi i te mara, kia rite ki te whakatutuki i ngā hiahia o te heke mai. Ahakoa i roto i te hanga, te hinu me te hau, te pūngao whakahou rānei, ka whai wāhi nui te Paipa Whakarewa Takirua ki te hanga i te hanganga o te heke mai.
