Ko te tikanga o te "takirere pūrerehua 150" e rua ngā tawhā noa:
- DN150: Te whānui ingoa 150mm (he rite ki te 6 inihi i roto i te NPS).
- 150lb / 150 / Akomanga 150: Te whakatauranga pēhanga ANSI/ASME Akomanga 150 (tata ki te 150 psi, he mea noa i roto i ngā pūnaha paerewa o Amerika, he ōrite ki te PN20 i Haina/Tiamana).
1. Ngā Ahu o te Takirere Pūrerehua DN150 / 6"
Ko ngā momo takirere pūrerehua ko te Wafer, te Lug, me te Double Flanged. Kei roto i ngā raraunga e whai ake nei ngā tawhā matua e hangai ana ki ngā paerewa pēnei i te ASME B16.5.
1.1 Momo Angiangi/Momo Tūhonohono (Momo Here/Momo Tūhonohono, hononga poto noa, e rite ana ki te ISO 5752):
- Roa o te kanohi ki te kanohi: 55–57 mm
- Teitei Katoa (te pou tahanga kāore he actuator): 320–400 mm (pūmau/mahi teitei)
- Rahi o te toki:≈14*14mm
1.2 Momo Taparua (Hononga Taparua, e rite ana ki te ISO 5752):
- Roa Mata-ki-Mata: Tata ki te 140mm/210mm
- Teitei Katoa (te pou tahanga kāore he kaiwhakaoho): 410 mm/589mm (pokapū/takirua) 2. Ngā Tawhā Taketake o te Flange ASME B16.5 Akomanga 150 (E pā ana ki te NPS 6" / DN150)
Koinei te paerewa mō ngā hononga flange takirere pūrerehua (me whai flange paipa ōrite te momo Wafer/Lug, ka tae mai te momo Double Flanged me te flange).
| Tawhā | Uara (inihi) | Uara (mm tata) | Ngā Tuhipoka |
| Diameter o Waho o te Flange (OD) | 11.00 | 279.4 | |
| Te Diameter o te Porowhita Pūtu | 9.50 | 241.3 | |
| Te maha o ngā pūtu | 8 | – | |
| Rahi o te Pūtu | 3/4" | Taurite M20 | Ngā miro UNC 3/4"-10 |
| Te Diameter o te Pūwero | 0.88 | 22.2 | |
| Diameter o te Mata Whakaarahia | 8.50 | 215.9 | He mea noa mō ngā flange RF |
| Matotoru o te Flange (min) | 1.00 | 25.4 | Tae atu ki te mata kua ara ake |
3. Tūtohi me te Taipana o te Pūtu Flange 150
3.1Ngā Whakatakotoranga Pūtu NPS 6" Akomanga 150:
- Te maha o ngā Pūtu: 8
- Te whānui o te pūtu: 3/4"
- Te Roa o te Pūwero Tūhono e Manakohia ana (1/16" RF): Tata ki te 4 inihi (102 (mm)
Te taipana pūtu flange e taunakitia ana mō te tāutanga o te takirere pūrerehua (whai muri i te whakahinuhinu, te whakakīkī whakawhiti):
| Rahi o te Takirere | Rahi o te Pūtu | Taipana iti rawa (ft-lb) | Te Taipana Mōrahi (ft-lb) |
| 5"–8" | 3/4" | 30–40 | 100–120 |
3.2 Ngā Hipanga Whakakīkī (Whakakīkī-Whatunga):
a. Rāuna Tuatahi: 30% Taipana
b. Rāuna Tuarua: 60% Taipana
c. Rauna Tuatoru: 100% Taipana
d. Wāhanga Whakamutunga: Tirohia te taha matau/te taha maui
