Ka peka ke tetahi pito o te whakaiti porowhita mai i te pokapū o te paipa, ka puta he whakawhiti porowhita. Ka whakamahia tēnei momo whakaiti ina hiahiatia hei pupuri i ngā hononga waikeri, whakapūhau rānei, hei karo rānei i te hau, i te hau rānei e mau ana i roto i te pūnaha. He rerekē, ko ngā pito e rua o te whakaiti porowhita e hangai ana ki te pokapū, e whakarato ana i te whakawhiti ōrite i waenga i ngā rahi paipa.
4. He aha te SCH80? He aha tōna hiranga?
Ko te SCH80 e pā ana ki te matotoru o te paipa, o te hononga rānei, i tēnei wā he mea whakawhāiti i te hononga o te maitai kore waikura. He waehere paerewa tēnei e whakamahia ana hei whakaatu i ngā matotoru pakitara motuhake mō ngā paipa me ngā hononga. Ko te tohu SCH80 e tohu ana he matotoru ake ngā pakitara o te rauemi i te SCH40, e whakarato ana i te kaha miihini me ngā whakatauranga pēhanga teitei ake mō ngā tono uaua.
5. Ka taea te whakamahi i te SCH80 SS316 kowiri tira whakaiti-āhua rerekē me ngā rauemi rerekē?
Ae, ka taea te whakamahi i ngā Whakaiti Whakarewa Kowiri tira SCH80 SS316 me ngā rauemi rerekē, engari he mea nui kia whakaarohia te hototahitanga. Ko te kowiri tira he hototahi ki ngā momo rauemi, engari me kōrero ki tētahi tohunga ahumahi kia pai ai te hototahitanga, me te whakaaro ki ngā āhuatanga pēnei i te pāmahana, te pēhanga me te ātete matū.
6. Me pēhea te tāuta i te SCH80 SS316 kowiri tira hei whakaiti i te weranga o te pūwero?
Ko te tukanga tāutanga mō te SCH80 SS316 Stainless Steel Butt Weld Eccentric Reducer ko te tapahi i te paipa ki te wāhi e hiahiatia ana, kia ma ai, kia tapawhā ai te tapahi. Me whakarite te whakaiti ki ngā pito e rua o te paipa, ā, me mahi te tukanga whakarewa i runga anō i ngā paerewa me ngā aratohu a te ahumahi. Me whakarite kia tika te whakarite me ngā tikanga whakarewa tika kia hanga he hononga kaha, kāore hoki e turuturu.
7. He aha ngā whakamahinga noa o te SCH80 SS316 he mea whakarewa-kowiri tira, he mea hanga ki te whakarewa?
He maha ngā whakamahinga o ngā Whakaiti Whakakotahitanga Kowiri tira SCH80 SS316 i roto i ngā momo ahumahi me ngā tono. He maha ngā wā ka kitea i roto i ngā tipu tukatuka matū, i ngā whare whakapai hinu me te hau, i te umanga rongoā, i ngā tipu tukatuka kai me ngā whare maimoatanga wai. He pai ēnei whakaiti mō ngā tono e hiahia ana ki te roa, te ātete ki te waikura me te rere pai o te wai.
8. He aha ngā tiwhikete, ngā paerewa rānei e tika ana kia tutukihia e te SCH80 SS316 he mea whakarewa maitai kore waikura?
I te wā e whiriwhiri ana i te taputapu whakaiti ira whakarara SCH80 SS316, he mea nui kia whakarite kia tutuki i ngā tiwhikete me ngā paerewa e tika ana. Ko ngā paerewa e whakamahia whānuitia ana ko te ASTM (American Society for Testing and Materials), ASME (American Society of Mechanical Engineers), me te ANSI (American National Standards Institute). Hei tāpiri, me whai tiwhikete whakahaere kounga pēnei i te ISO 9001:2015.
9. Ka taea te whakarite i te whakaiti rerekē i hangaia ki te kowiri tira SCH80 SS316?
Āe, ka taea te whakarite i ngā Whakaiti Whakapūmau Kowiri tira SCH80 SS316 kia tutuki ai ngā whakaritenga kaupapa motuhake. Tērā pea ko ngā kōwhiringa whakaritenga he rerekē ngā diameter pito, he roa, he whakarerekētanga rānei hei whakauru i ngā whirihoranga paipa ahurei. E taunakihia ana kia kōrero ki te kaihanga, ki te kaiwhakarato rānei hei matapaki i ngā kōwhiringa whakaritenga me ngā whakaritenga.
10. Me tiaki te whakawhāiti rerekē o te maitai kore waikura SCH80 SS316?
Ko ngā Whakaiti Whakaheke Kowiri tira SCH80 SS316 he iti noa te tiaki e hiahiatia ana nā te mea he ātete ki te waikura me te roa o te wā. Heoi, e taunakihia ana kia tirohia te whakaiti i ia wā mō ngā tohu pakaru, turuturu rānei. Hei tāpiri, he mea nui te tirotiro auau i te pūnaha paipa katoa me ngā mahi tiaki tika, e ai ki ngā aratohu a te ahumahi, kia pai ai te mahi me te roa o te wā.
He mea nui ngā hononga paipa i roto i te pūnaha paipa, e whakamahia ana mō te hononga, te huri i te taha, te huri i te taha, te whakarerekē i te rahi, te hiri, te whakahaere rānei i te rere o ngā wai.
