He kaiwhakarato wheketere Haina mō ngā takirere porowhita maitai whakarewa ASME BS1873 te hanga ngaio
He aha te takirere porowhita BS1873?
BS1873 takirere porowhita
Ko tētahi o ngā hoahoa rongonui o ngā takirere porowhita, mō te pūnaha US me te API. Ko te diameter o roto, ngā rauemi, te mata ki te mata, te matotoru o te pakitara, te pāmahana pēhanga, kua tautuhia e te ASME B16.34.
teBS1873 takirere porowhitaka taea hoki te whakamahi mō ngā mahi whakatere. He maha ngā tinana takirere kotahi-nohoanga e whakamahi ana i te hanganga kākahu, i te momo pupuri rānei hei pupuri i te mowhiti nohoanga, hei ārahi i te mono takirere, hei whakarato hoki i tētahi huarahi hei whakatū i ngā āhuatanga rere takirere motuhake. Ka taea hoki te whakarerekē ngāwari mā te whakawhiti i ngā wāhanga whakapaipai hei whakarerekē i te āhuatanga rere, hei whakarato rānei i te kaha iti.te rere, te whakaiti i te haruru, te whakaiti, te whakakore rānei i te pokanga.
Ngā Tauira Tinana Takirere Porowhita ASME, e toru ngā tauira tinana matua, ngā hoahoa rānei mō ngā takirere Porowhita, arā:
- 1). Tauira Paerewa (e mōhiotia ana ko te Tauira T, Tauira T rānei, Tauira Z rānei)
- 2). Tauira Koki
- 3). Tauira Whakarara (e mōhiotia ana ko te Tauira Wye, ko te Tauira Y rānei)
Te Kaupapa Mahi oBS1873 takirere porowhita
He kōpae nekeneke te mea hanga o te takirere porowhita, me te nohoanga mowhiti tūmau i roto i te tinana porowhita. Kei waenganui te nohoanga o te takirere porowhita, ā, kei te whakarara ki te paipa, ā, ka katihia te whakatuwheratanga o te nohoanga ki te kōpae. Ina hurihia ā-ringa te wira ringaringa, mā te whakamahi rānei i te kaiwhakaoho, ka whakahaeretia te nekehanga o te kōpae (ka whakahekehia, ka hikitia rānei) mā te kakau takirere. Ina noho te kōpae takirere porowhita ki runga ake i te mowhiti nohoanga, ka mutu katoa te rere.
Āhuatanga matua o te takirere porowhita BS1873
- 1). Ngā āheinga hiri pai
- 2). He poto te tawhiti haere o te kōpae (whiu) i waenga i ngā tūranga tuwhera me ngā tūranga kati,Ngā takirere porowhita ASMEhe mea tino pai mēnā me whakatuwhera, me kati pinepine te takirere;
- 3).Ka taea te whakamahi i te takirere porowhita ASME hei takirere aukati-tātari mā te whakarerekē paku i te hoahoa.
- 4).TAnei te whānuitanga o ngā āheinga e wātea ana i roto i ngā momo tinana tee, Wye, me te koki.
