Jaloteräksiset aallotetut letkut

DEKOMTE jaloteräksiset aallotetut letkut ovat kestäviä, hyvin joustavia ja tiiviitä putkitekniikassa käytettyjä rakennusosia. Ne täyttävät mitä parhaiten tämän teknologian asettamat vaatimukset paineenkestävyydestä, tyhjiötiiviydestä, lämpötilankestävyydestä, korroosiosuojasta, joustavuudesta ja pitkäikäisyydestä.

Käyttö

DEKOMTE jaloteräksisiä aallotettuja letkuja voidaan käyttää melkein kaikille nestemäisille ja kaasumaisille aineille sekä pumpattaville kiinteille aineille, tarvittaessa PTFE-pinnoitteella varustettuina suojaamaan erityisen agressiivisten aineiden vaikutuksilta tai tarttumatonta sisäpintaa valmistettaessa (DEKOMTE PTFE-kemialliset letkut).

Ominaisuudet

Letkut tasaavat venymisliikkeitä, toimivat joustavina liitoksina liikkuvien osien ja staattisten koneiden tai laitteistojen välillä, taasaavat värähtelyjä tai niitä käytetään välttämättömien asennustoleranssien tasaamiseksi. Useasti niitä käytetään esimerkiksi sammutus- ja lastausletkuissa tai säiliöletkuissa.

Jos haluat välttää mekaaniset vaikutukset, luvattomat taivutukset tai hankauksen, voimme toimittaa letkut myös ulkoisella tai sisäisellä  jaloteräksisellä spiraaliletkulla varustettuina. Pyynnöstä voimme varustaa letkut myös ulkoisella lämpöeristyksellä, joka mahdollistaa vaarattoman letkun käsittelyn. DEKOMTE jaloteräksisiä aallotettuja letkuja voidaan käyttää kaikissa lämpötiloissa -196 °C – +600 °C välillä, täystyhjiöstä 200 barin paineeseen asti
