Dugukolo jukɔrɔ tilennen sutura insulated steel pipe ye direct-buried prefabricated thermal insulation steel pipe ni funteni insulasi baarakɛcogo ɲuman, lakana ani dannaya, ani jɔli musaka dɔgɔyali.
A ɲɛfɔli .
1. Pre-Insulated steel pipe min datugulen don ni poliyuritani fomu ye min ka bon kosɛbɛ, o bɛ se ka funteni kunbɛn fo ka se degere 140 ma c.
2. Ni HDPE jakite pipe bɛ se ka pipe kɛ ka a su don dugujukɔrɔ k’a sɔrɔ a ma kɛ ni bɔgɔdaga ye.
3. Pipe ni pipe fitininw hakɛ danfaralenw bɛ se ka baara kɛ walasa ka funteni ni nɛnɛ porozɛ wɛrɛw kɛ.
4. Poliyuritan fomu janya bɛ se ka dilan ka bɔ 26,5-83mm walima ka tɛmɛ o kan.
Fɛn minnu bɛ kɛ ka fɛnw dilan .
Baara min bɛ kɛ ni nɛgɛ ye .
Core layer, min bɛ medium ta (i n’a fɔ ji funteni walima watara), o bɛ dilan ni sanfɛ-QUALITAL ye min bɛ kɛ ni nɛgɛ pipe ye min tɛ fɛn tiɲɛ walima min bɛ sɔgɔ ni sumaya ye ani a ka kan ka tugu tansiyɔn jiginni sariyaw kɔ (misali la, 100% radiyografu sɛgɛsɛgɛli).
Insulation .
Poliyuritani fomu gɛlɛn (densité 60-80 kg/m3) ye fɛn fɔlɔ ye, min bɛ funteni jiginni dɔgɔya (0,013-0,03 kcal/m:h·℃) ani hakɛ dafalen{6}}cell hakɛ min ka bon walima ka bɛn 90% ma, o bɛ funteni bɔnɛ dɔgɔya kosɛbɛ. For high-temperature applications (such as steam pipelines), a multi-layer, staggered-stitch composite insulation structure (including an aluminum foil reflective layer) is used, offering a temperature resistance of 150℃-450℃.
kɛnɛma pipe .
High-density polyethylene (HDPE) or steel-in-steel (double-layer steel pipe structure) provides corrosion resistance, waterproofing, and mechanical protection. The HDPE outer pipe requires corona treatment on the inner surface, has a density >940 kg/m³, and a tensile strength >20 MPa. O fɛn dilanni taabolo bɛ iziniw dilanni daminɛ ani u dilanni jɛlen, i n’a fɔ nɛgɛ pibilikiw bɔli nɔgɔ la, insulation layer famu, ani kɛnɛma lakanani pipew pakeli walasa ka a dɔn ko layini saba ninnu sirilen don ɲɔgɔn na kosɛbɛ.
