DS-TWE ED-03 SCHEDA PRODOTTO DATA SHEET THERMOWELLS Un pozzetto termometrico è un rivestimento a innesto termicamente conduttivo consigliato per proteggere strumenti da eventuali effetti corrosivi di processo e permettere la manutenzione o la sostituzione di strumenti per ricalibrazione, senza necessità di interrompere il funzionamento di processo. I pozzetti sono disponibili per late pressione, alte temperature e Applicazioni in cui le velocità dei fluidi sono elevate. Vengono selezionati sulla base delle variabili pressione, temperatura, portata, vibrazioni ed effetti corrosivi. A thermowell is a thermally conductive socket recommended to: - protect delicate instrument sensing elements against corrosive effects - permit instrument interchange or calibration check without disturbing or closing down the process. Thermowell are available for high pressures, high temperatures and high velocity applications Selected on the basis of pressure, temperature, flow, vibration and corrosion service parameters, basic thermowell types include: - barstock execution or built-up execution - Threaded - Socket Welded - Flanged MATERIAL Standard materials: AISI316 / 316-Ti / 304 / 321 Special materials such as: Duplex / Monel / Titanium / Nickel / Hastelloy C276 Hastelloy C4 / Inconel 600 / Incoloy 800...&.C Special materials (sheets) for coating wetted parts: Tantalum / PTFE / Hastelloy C276 / Hastelloy C4 / Zirconium DOCUMENTATION AND TEST Construction drawing Hydrostatic test pressure Dye penetrant test Inspection and material certificate according to EN10204 3.I.B., 3.I.C Heat number stamped on well and flange Certificate according to NACE MR.01.75 Tensile test, impact test Heat treatment certificate HUEY test to ASTM A 262-C Performance test to ASME PTC 19.3 Welding Procedure Specification (WPS) Procedure Qualification Record (PQR) IDENTIFICATION Every thermowell is supplied clearly identified with: Tag n.
