"Vharuvhu yebhatafurayi 150" inowanzo sanganisira maparamita maviri akafanana:
- DN150: Dhayamita yepakati 150mm (yakaenzana nemasendimita matanhatu muNPS).
- 150lb / 150 / Kirasi 150: Kuyera kumanikidzwa ANSI/ASME Kirasi 150 (inenge 150 psi, inowanikwa mumasystem eAmerican standard, yakaenzana nePN20 muChina/Germany).
1. Zviyero zveVharuvhuti yeDN150 / 6"
Mhando dzemavharuvhu emashavishavi dzinosanganisira Wafer, Lug, uye Double Flanged. Ruzivo runotevera runopfupikisa maparamita akakosha zvichibva pamiyero yakaita seASME B16.5.
1.1 Rudzi rweWafer/Lug (Rudzi rweClip-on/Lug, common short connection, inoenderana neISO 5752):
- Kureba Kwechiso Nechiso: 55–57 mm
- Kureba Kwese (mugodhi usina chinhu usina actuator): 320–400 mm (kureba/kushanda kwepamusoro)
- Saizi yemugodhi:≈14*14mm
1.2 Rudzi rweFlanged Double (Kubatana kweFlanged Double, kunoenderana neISO 5752):
- Kureba kweChiso Nechiso: Inenge 140mm/210mm
- Kureba Kwese (mugodhi usina chinhu usina actuator): 410 mm/589mm (concentric/double) 2. ASME B16.5 Class 150 Flange Basic Parameters (Inoshanda kuNPS 6" / DN150)
Uyu ndiwo mwero wekubatanidza flange yemabhatafurayi (Rudzi rweWafer/Lug runoda flange yepombi inoenderana, Rudzi rweDouble Flanged runouya neflange).
| Paramita | Kukosha (masendimita) | Kukosha (mm inenge) | Zvinyorwa |
| Dhayamita yekunze yeFlange (OD) | 11.00 | 279.4 | |
| Dhayamita yedenderedzwa rebhoti | 9.50 | 241.3 | |
| Huwandu hweMabhoti | 8 | – | |
| Saizi yeBhodhi | 3/4" | M20 yakaenzana | UNC 3/4"-10 tambo |
| Dhayamita yeBhodhi | 0.88 | 22.2 | |
| Dhayamita yeChiso Chakasimudzwa | 8.50 | 215.9 | Zvakajairika kune RF flanges |
| Ukobvu hweFlange (min) | 1.00 | 25.4 | Kusanganisira chiso chakasimudzwa |
3. Chati yeFlange Bolt 150 & Torque
3.1Magadzirirwo eBolt yeKirasi 150 NPS 6":
- Nhamba yeMabhoti: 8
- Dhayamita yeBhodhi: 3/4"
- Kureba Kwebhaudhi Rinokurudzirwa (1/16" RF): Inenge mainji mana (102 (mm)
Inokurudzirwa kushandisa flange bolt torque yekuisa butterfly valve (mushure mekuzora mafuta, kusimbisa muchinjikwa):
| Saizi yeVharuvhu | Saizi yeBhodhi | Min Torque (ft-lb) | Max Torque (ft-lb) |
| 5"–8" | 3/4" | 30–40 | 100–120 |
3.2 Matanho Ekusimbisa (Kusimbisa Zvakafanana):
a. Danho Rokutanga: 30% Torque
b. Danho rechipiri: 60% Torque
c. Danho rechitatu: 100% Torque
dDanho Rekupedzisira: Tarisa uchitenderera wachi/wachi uchipesana newachi
