Valves z'umupira zisudiwegutanga imiyoboro ihoraho kandi idapfukirana mu buryo bw'ingenzi bwo gukurura imiyoboro. Gusobanukirwa itandukaniro ry'ibanze hagati yo gusudira solvent na thermal welding ni ingenzi kugira ngo hatoranywe neza valve:
| Igipimo | Valves z'umupira wo gusudira solvent | Valves z'umupira wo kogosha ubushyuhe |
| Uburyo bwo guhuza | Guhuza imiti ya thermoplastics | Gushonga ibyuma (TIG / MIG gusudira) |
| Ibikoresho | PVC, CPVC, PP, PVDR | Icyuma kidasembuye, icyuma cya karuboni |
| Ubushyuhe ntarengwa | Ubushyuhe bugera kuri 60°C | Ubushyuhe bugera kuri 1200°F+ (650°C+) |
| Igipimo cy'umuvuduko | Icyiciro cya 150 | Icyiciro cya 150-2500 |
| Porogaramu | Gutanga imiti, gutunganya amazi | Amavuta/gaze, umwuka w'amazi, imiyoboro y'umuvuduko mwinshi |
Ubwoko bw'amarangi y'umupira yasutswe
1. Valves z'umupira zisutswe neza
–Imiterere: Umubiri w'icyuma kimwe udafite imigozi/gaskets
–Ibyiza: Garanti y'uko nta gusohoka kw'amazi, igihe cy'imyaka irenga 30 yo gukora
–Amahame: ASME B16.34, API 6D
–Ibikoresho byo Gukoresha: Imiyoboro yo munsi y'ubutaka, porogaramu zo munsi y'inyanja, ibyuma bya LNG
2. Valves z'umupira zikozwe muri Semi-Welded
–Igishushanyo mbonera cy'ubwoko bwa Hybrid: Umubiri ushongeshejwe + agapfundikizo gafite umugozi
–Gusana: Gusimbuza igipfundikizo nta gukata imiyoboro
–Inganda: Gutanga amashanyarazi, gutunganya imiti
–Igitutu: Icyiciro cya 600-1500
3. Valves z'imipira zikozwe mu byuma bitagira umugese
–Amanota: 316L, 304, duplex, super duplex
–Ubudahangarwa bw'inkongiIhangana na kloride, aside, H₂S
–Impamyabushobozi: NACE MR0175 igenewe serivisi nziza
–Amahitamo y'isuku: 3A ijyanye n'ibiribwa/imiti
Porogaramu zo mu nganda hakurikijwe ubwoko
| Inganda | Ubwoko bwa Valve Isabwa | Inyungu y'ingenzi |
| Gutunganya imiti | Valve za CPVC zo gusudira solvent | Ubudahangarwa bwa aside sulfuriki |
| Peteroli na Gazi | Vali za SS316 zisutswe neza | Icyemezo cya API 6FA cyo kwirinda inkongi y'umuriro |
| Ubushyuhe bw'Akarere | Vali z'icyuma cya karuboni zikozwe mu buryo bwa semi-sudded | Ubudahangarwa bw'ingufu ziterwa n'ubushyuhe |
| Farumasi | Vali z'icyuma gisukuye | Ubuso bukozwe n'amashanyarazi |
NSW: Uruganda rwemewe rwo gusuka umupira w’amashanyarazi
Nk'umuntuIcyemezo cya ISO 9001 na API 6Duruganda rukora valve y'umupira wo gusudira, NSW itanga:
- Intera idahuye: Vali ½” kugeza kuri 60″ (ANSI 150 – 2500)
– Ubusudizi bwihariye:
– Gusudira mu kirere hakoreshejwe uburyo bwa "orbital" kugira ngo bikoreshwe mu bikorwa bya kirimbuzi
– Uburyo bwo kuvura indwara ya Cryogenic (-320°F/-196°C)
- Ubushobozi bwo gukubita cyane
– Ubuhanga mu bikoresho:
– ASTM A351 CF8M icyuma kitagira umwanda
– Alloy 20, Hastelloy, titanium
– Amahitamo ya PTFE/PFA afite umurongo
– Porogaramu y'igerageza:
– Isuzuma ry’amazi ya heliyumu 100%
– Ibizamini by'intebe bya API 598
– Ibyuka bihumanya ikirere bituruka ku guhunga (ISO 15848-1)
