A ka c’a la, lastikuw dilanni funteni ye t≤150°C ye, ani lastikuw nafama funteni ye t≤60°C ye.Lastikuw bɛ kɛ ka globo valvew datugu,lastikuw sigilen da da wulilan, diaphragme valves, .ruber sigilen butterfly valve, ruber sigilen swing check valve (sɛgɛsɛgɛlikɛlanw (valve).), pinɛ-minɛnw ni fɛn wɛrɛw minnu ka tansiyɔn tɔgɔlama ye PN≤1MPa ye.
2. Nilon (Nylon) ye
Nilon bɛ ni sɔgɔsɔgɔninjɛ hakɛ fitinin ye ani a bɛ se ka sɔgɔsɔgɔ koɲuman. Nilon bɛ kɛ ka caya bololabaarakɛminɛnw ni globolanw na minnu funteni ye t≤90°C ye ani u tansiyɔn tɔgɔlama ye PN≤32MPa ye.
3. PTFE (PTFE) ye
PTFE bɛ kɛ ka caya globo valvew kama,da wulilenw, bololanɛgɛw, a ɲɔgɔnnaw ni funteni t≤232°C ani tansiyɔn tɔgɔlama PN≤6.4MPa.
4. Nɛgɛdaga
Nɛgɛdaga bɛ kɛ ka...da wulilen, globo valve, plug valve, wdfl ka ɲɛsin funteni t≤100°C ma, tansiyɔn tɔgɔlama PN≤1.6MPa, gazi ni tulu.
5. Babbitt ka sɔgɔsɔgɔninjɛ
Babbitt alloy bɛ kɛ ka amoniyɔmu globe valve kɛ ni funteni t-70~150°C ani tansiyɔn tɔgɔlama PN≤2.5MPa.
6. Kupu sɔgɔlen
Fɛn minnu bɛ kɛ ka caya nɛgɛso la, olu ye 6-6-3 tintin nɛgɛ ye ani 58-2-2 manganɛsi nɛgɛ ye. Kupu sɔgɔlen bɛ se ka sɛgɛn ka ɲɛ, wa a bɛnnen don ji ni watara ma ni funteni t≤200°C ye ani tansiyɔn tɔgɔla PN≤1.6MPa. A ka teli ka kɛ san...da wulilenw, globo valvew, .sɛgɛsɛgɛlikɛlanw (valve)., fiɲɛbɔlanw, a ɲɔgɔnnaw.
7. Kɔrɔmu nɛgɛ inox
Kɔrɔmu nɛgɛ suguya minnu bɛ kɛ ka caya, olu ye 2Cr13 ani 3Cr13 ye, minnu fagara ka u sumaya, wa u bɛ se ka sɔgɔsɔgɔ ka ɲɛ. A ka c’a la, a bɛ kɛ valvew kɔnɔ fɛnw kama i n’a fɔ ji, watara ani petoroli ni funteni t≤450°C ani tansiyɔn tɔgɔlama PN≤32MPa.
8. Kɔrɔmu-nikɛri-titaniyɔmu nɛgɛ min tɛ sɔgɔ
Kɔrɔmu-nikɛri-titaniyɔmu nɛgɛ suguya min bɛ kɛ ka caya, o ye 1Cr18Ni9ti ye, min bɛ se ka sɔgɔsɔgɔ ka ɲɛ, a bɛ se ka sɔgɔsɔgɔ ani ka funteni kɛlɛ. A bɛnnen don watara, asidi azotiki ani fɛn wɛrɛw ma minnu funteni ye t≤600°C ye ani tansiyɔn tɔgɔla PN≤6.4MPa, a bɛ kɛ ka globo valve, ball valve, a ɲɔgɔnnaw kɛ.
9. Nɛgɛ min bɛ ni nitiriti ye
Nitirili nɛgɛ suguya min bɛ kɛ ka caya, o ye 38CrMoAlA ye, min bɛ se ka sɔgɔsɔgɔ ka ɲɛ ani ka sɔgɔsɔgɔ ka ɲɛ karɔbɔli furakɛli kɔfɛ. A ka ca a la, a bɛ kɛ kuran feereyɔrɔ da wulilan na ni funteni t≤540°C ye ani tansiyɔn tɔgɔlama PN≤10MPa.
10. Boronize (Boroni) kɛli
Boronizing bɛ sigilan baara k’a ɲɛsin a ma ka bɔ valve farikolo walima disiki farikolo fɛnw na, o kɔfɛ a bɛ boronizing surface furakɛli kɛ, sigilan bɛ se ka sɛgɛn ka ɲɛ. A bɛ kɛ ni kuran sɛnɛyɔrɔ fiɲɛbɔlan ye.
