NGĀ PAEREWA WHĀNUI
Rīpene Hononga Taupoki
E rua ngā wāhanga paipa e hiahiatia ana mō te hononga whakarara, arā, he pito porotaka me he porotaka tautoko korekore. Ka uru te porotaka tautoko korekore ki runga i te diameter o waho o te pito porotaka, he mea whakapiripiri ki te paipa. Kāore te porotaka tautoko i whakapiripiritia ki te paipa, ā, ka taea te huri, he mea tino whai hua ina hiahiatia te whakatakoto i ngā porotaka i te wā e whakatūria ana.
Waihoki, nā te mea kāore te flange tautoko e pā ki te wai tukanga, ka taea te hanga i tētahi rauemi iti ake te ātete ki te waikura. Hei tauira, ki te mea he waikura te tukanga, ā, me hanga te paipa ki te maitai kore waikura, pērā i te ASTM A312 TP316L, me hanga hoki te pito o te pou ki te SS 316L; heoi, ka taea te hanga i te flange tautoko ki te ASTM A105, he iti ake te utu.
Kāore tēnei tikanga hononga i te tino pakari pērā i te hononga kaki whakarewa engari he pai ake i ngā hononga wiri, hononga kōtui, me ngā hononga paheke; heoi, he nui ake te utu ki te whakamahi, nā te mea me whai hononga whakarewa uru katoa, ā, e rua ngā wāhanga e hiahiatia ana.
PUTUNGA O TE PITO
Ka whakamahia tonutia he Pito Tūpou me te flange Hononga Lap, hei flange tautoko.
Ka whakamahia ēnei hononga flange, i roto i ngā tono pēhanga iti me ngā tono kore-tino nui, ā, he tikanga flanging iti te utu.
Hei tauira, i roto i tētahi pūnaha paipa kowiri tira, ka taea te tāpiri i tētahi flange maitai waro, nā te mea kāore e pā atu ki te hua i roto i te paipa.
Kei te wātea ngā pito pūmau i roto i te nuinga o ngā diameter o ngā paipa. Kei roto i te paerewa ASME B.16.9 ngā āhuatanga me ngā āheinga āhuatanga. Kei roto hoki i te MSS SP43 ngā pito pūmau ātete-waikura māmā.
PAINGA O TE RĀRANGI HUI PŪ
- Mā te herekore ki te hurihuri huri noa i te paipa ka māmā ake te whakarārangi i ngā kōhao pūtu o te flange e anga whakarara ana.
- Nā te kore e pā ki te wai i roto i te paipa, ka taea te whakamahi i ngā flange maitai waro utu iti me ngā paipa ātete ki te waikura.
- I roto i ngā pūnaha e tere ana te memeha, te waikura rānei, ka taea te whakaora i ngā flange hei whakamahi anō.
Whakaaturanga Taipitopito o ngā Hua
1. Kanohi
mata papatahi, ko te pūtoro te mea nui rawa atu
2. Me te pū, kāore rānei he pū
3. Whakaotinga mata
Ko te whakaotinga o te mata o te flange ka inehia hei Arithmetical Average Roughness Height (AARH). Ka whakatauhia te whakaotinga e te paerewa e whakamahia ana. Hei tauira, ka tohua e te ANSI B16.5 ngā whakaotinga mata i roto i te awhe 125AARH-500AARH (3.2Ra ki te 12.5Ra). Kei te wātea ētahi atu whakaotinga mēnā ka tonoa, hei tauira 1.6 Ra max, 1.6/3.2 Ra, 3.2/6.3Ra, 6.3/12.5Ra rānei. Ko te awhe 3.2/6.3Ra te mea tino noa.
TE TOHU ME TE TAKAI
• Ka whakamahia e ia paparanga he kiriata kirihou hei tiaki i te mata
• Mō ngā mea katoa he kowiri tira, ka tākaihia ki te pouaka rakau. Mō ngā mea nui ake, ka tākaihia ngā flange waro ki te papa rakau. Ka taea rānei te whakarite i te tākai.
• Ka taea te hanga tohu tuku mēnā ka tonoa
• Ka taea te whakairo, te tā rānei i ngā tohu i runga i ngā hua. E whakaaetia ana te OEM.
TE TIROTIRO
• Whakamātautau UT
• Whakamātautau PT
• Whakamātautau MT
• Whakamātautau ine
I mua i te tukunga, ka whakaritea e tā mātou tīma QC te whakamātautau NDT me te tirotiro ine. Ka whakaaetia hoki te TPI (tirotiro tuatoru).
TE TUKANGA HANGA
| 1. Kōwhiria te rauemi mata tūturu | 2. Tapahia ngā rauemi mata | 3. Te whakamahana-mua |
| 4. Te Hanga | 5. Te maimoatanga wera | 6. Mīhini Taratara |

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. He whānuitia te whakamahinga o ēnei i roto i ngā mara pēnei i te hanga, te ahumahi, te pūngao me ngā ratonga ā-tāone.
Ngā Mahi Matua:Ka taea e ia te mahi i ngā mahi pēnei i te hono i ngā paipa, te whakarerekē i te ahunga rere, te wehewehe me te whakakotahi i ngā rere, te whakarerekē i te diameter o ngā paipa, te hiri i ngā paipa, te whakahaere me te whakatikatika.
Whānuitanga o te tono:
- Te tuku wai me te rerenga wai o te whare:E whakamahia ana ngā tuke PVC me ngā tuke PPR mō ngā whatunga paipa wai.
- Ngā paipa ahumahi:E whakamahia ana ngā flange kowiri tira me ngā tuke koranu hei kawe i ngā pāpāho matū.
- Te kawe pūngao:E whakamahia ana ngā paipa maitai pēhanga teitei i roto i ngā paipa hinu me te hau.
- HVAC (Whakamahana, Whakahauora, me te Āhuarangi):E whakamahia ana ngā hononga paipa parahi hei hono i ngā paipa whakamatao, ā, e whakamahia ana ngā hononga ngāwari hei whakaiti i te wiri.
- Te whakamakuku ahuwhenua:Mā ngā hononga tere ka taea te huihui me te wetewete i ngā pūnaha whakamakuku pīni.
