Ka Taea te Whakamahi i ngā Takirere Pōro mō te Kohu: He Aratohu Kōwhiringa Takirere Paipa

Aratohu Kōwhiringa Takirere Paipa Kohu: Ngā Whakaritenga Takirere Pōro me ngā Momo Noa

Ko ngā pūnaha mamaoa ahumahi e hiahia ana kia tika te whiriwhiri i ngā takirere hei painga mō te haumaru me te whai huatanga.Ngā takirere pōroMe mahi noa i roto i ngā paipa mamaoa ina tutuki ngā tikanga tino pakari: te ātete ki te pāmahana teitei/pēhanga, te hiri pakari, me ngā hoahoa motuhake ki te mamaoa (hei tauira, ngā takirere pōro hiri-mārō katoa). Anei te whakamārama hangarau:

1. Ngā Whakaritenga Matua mō ngā Takirere Pōro Kohu

◼ Ngā Paerewa Rauemi me ngā Hanganga

• Ngā Rauemi Pāmahana-Tiketike: Me whakamahi te maitai whakarewa ASTM A216 WCB, te mea ōrite rānei, mō ngā tinana takirere.
• Hoahoa Pūngao Katoa: Ka whakarite kia kore he here o te rere; me ōrite te akomanga pēhanga ki ngā paipa (hei tauira, Akomanga 150 = 2.0MPa).

◼ Te Mahi Hiri

• Ngā Hiri Mārō Anake: Ka pakaru ngā hiri ngohengohe i raro i ngā pāmahana mamaoa (>150°C).
• Hurihanga Pūmau: Me whakaiti te pakaru o ngā hoahoa pōro mānu/pūmau.

◼ Ngā Tikanga Pai mō te Whakahaere

• Tāutanga o te Kākano Poutū: Ka taea te huri tere i te 90° me te ārai i te turuturu.

◼ Ngā Whakatūpato Matua

• Ngā Whakamahinga: He mea tino pai mō te whakaweto/whakatika tere i te mamaoa i roto i ngā tipu hinu, matū, me te hiko.
• Ngā Herenga Rere: Ka horo te wai i te tere >40m/s – tīpakohia ngā tauira i runga i ngā tere rere o ngā paipa.
• Tiaki: Tirohia ngā hiri i ia toru marama, tangohia ngā putunga o roto, me te whai i ngā aratohu a te OEM.

2. Ngā Takirere Paipa Kohu Matua e 3 kua Whakatauritea

3. Ngā Whakaritenga mō te Takirere Mamao Whānui

Me whai āhuatanga ngā takirere mamaoa katoa:

1. Ātete ki te Pāmahana Nui: Pupuri i te mahi tonu >150°C.
2. Te Parenga ki te Waikura: Whakamahia te maitai kore waikura 316L mō te mamaoa waikura.
3. Hiri Kore-Tuku: Ārai i te ngaronga pūngao me ngā mōrearea haumaru.

4. Ngā Paerewa Whakatutukitanga me te Kōwhiringa

• Ngā Waehere Ao: Whāia te API 600, ASME B16.34, DIN/EN mō te hoahoa/whakamātautau.
• Paearu Kōwhiri: Whakatauritehia ngā āhuatanga o te takirere ki te pēhanga o te paipa, te pāmahana, te tere rere, me ngā rauemi.
• Tāutanga: Whai i ngā whakaritenga ANSI B31.1 mō te haumaru o te pūnaha mamaoa.

Whakarāpopototanga:

Ko ngā takirere porowhita, kuaha, me ngā takirere pōro e tutuki ana ngā whakaritenga matua mō ngā paipa mamaoa. Whakaritea ngā takirere pōro hiri-mārō me ngā tinana ASTM WCB, whakamanahia ngā tere rere (<40m/s), ā, whakatinanahia te tiaki paerewa.
