Ma valve a mpira wowotchereraperekani maulumikizidwe okhazikika komanso osataya madzi m'mapaipi ofunikira. Kumvetsetsa kusiyana kwakukulu pakati pa kuwotcherera kwa solvent ndi kuwotcherera kwa kutentha ndikofunikira kwambiri posankha bwino ma valavu:
| Chizindikiro | Ma Vavuluvulu a Mpira Wosungunula | Matenthedwe Weld Mpira mavavu |
| Njira Yolumikizira | Kuphatikizika kwa mankhwala a thermoplastics | Kusungunuka kwachitsulo (TIG/MIG welding) |
| Zipangizo | PVC, CPVC, PP, PVDR | Chitsulo chosapanga dzimbiri, chitsulo cha kaboni |
| Kutentha Kwambiri | 140°F (60°C) | 1200°F+ (650°C+) |
| Kuyeza kwa Kupanikizika | Kalasi 150 | Kalasi 150-2500 |
| Mapulogalamu | Kusamutsa mankhwala, kuchiza madzi | Mafuta/gasi, nthunzi, mizere yothamanga kwambiri |
Mitundu ya Valavu ya Mpira Wosefedwa Yofotokozedwa
1. Ma Vavu a Mpira Osefedwa Mokwanira
–Kapangidwe: Thupi la monolithic lopanda ma flanges/gaskets
–UbwinoChitsimikizo cha kutayikira kwa zero, moyo wautumiki wa zaka zoposa 30
–Miyezo: ASME B16.34, API 6D
–Makesi Ogwiritsira NtchitoMapaipi apansi panthaka, ntchito za pansi pa nyanja, malo oimikapo magetsi a LNG
2. Ma Vavu a Mpira Omwe Anasefedwa Mochepa
–Kapangidwe Kosakanikirana: Thupi lolumikizidwa + boniti yolumikizidwa
–Kukonza: Kusintha chisindikizo popanda kudula chitoliro
–MakampaniKupanga magetsi, kukonza mankhwala
–Kupanikizika: Kalasi 600-1500
3. Ma Vavu a Mpira Wopanda Zitsulo Zosapanga Chitsulo
–Magiredi: 316L, 304, duplex, super duplex
–Kukana Kudzikundikira: Imapirira ma chloride, ma acid, H₂S
–Ziphaso: NACE MR0175 ya ntchito yowawasa
–Zosankha Zaukhondo: 3A yogwirizana ndi chakudya/mankhwala
Ntchito Zamakampani ndi Mtundu
| Makampani | Mtundu Wovomerezeka wa Valavu | Phindu Lofunika |
| Kukonza Mankhwala | Ma valve a CPVC osungunula | Kukana kwa asidi wa sulfuriki |
| Mafuta ndi Gasi | Ma valve a SS316 olumikizidwa mokwanira | Satifiketi Yoteteza Moto ya API 6FA |
| Kutentha kwa Chigawo | Ma valve achitsulo cha kaboni chosungunuka pang'ono | Kukana kutentha kwa kutentha |
| Mankhwala | Ma valve achitsulo chosapanga dzimbiri chaukhondo | Malo opukutidwa ndi magetsi |
NSW: Wopanga Valve Yovomerezeka ya Weld Ball
MongaSatifiketi ya ISO 9001 & API 6Dwopanga mavavu a mpira wothira weldNSW imapereka:
- Unmatched Range: ½” mpaka 60″ ma valve (ANSI 150 – 2500)
- Kuwotcherera Kwapadera:
