Construction PTFE internal flexible line for the transport of liquids and gases. Armature consisting of one or two stainless steel braids guaranteeing pressure resistance. Hydraulic connectors mounted at ends of flexible line manufactured of very high quality material. Heat element wound around PTFE tube to ensure heating and temperature maintenance. The computer calculates the length and resistance. Interconnecting cables between the two ends of the flexible line for information (temperature) and power transfer. Thermal insulation adapted to operating temperatures and conditions. External braid for mechanical protection. Special assembly to prevent subsequent removal. Flexible line ends provided with silicon rubber protection fittings to ensure technically clean termination. Temperature sensor ( PT100, thermocouple,…) connected to electronic regulator maintaining transported product temperature, even for outside temperature variations. The flexible heating line meets the current standards.

The composition of the heated flexible line, resisting explosion, differs from the standard heating flexible line through the use of components approved by the European laboratories (L.C.I.E. P.T.B. etc.), such as heated cables, self-regulated heating tape, junction boxes, regulators, etc. eltrace can equip and supply all standard models, special flexible lines, stainless steel or copper tubes with a heating and control system approved for use in hazardous zones.Heating, in general, is by a heating cable conforming to European standards, heating tape with PTFE covered elements or self-regulating heated tape. The corresponding control certificates are included with the equipment. Because this equipment is manufactured to order only, our "project managers" are available to our customers for any information or special studies. For the application of expanded polyurethane Double flexible heating line for two-part flexible projection with two PTFE tubes, one resisting pressure and one for compressed air.Nominal diameter: 2 x 6mm to 2 x 13mm.Maximum operation temperature: 80°C For the analysis technique PTFE heating flexible line bundlesSeveral PTFE tubes can be provided with heating, with the assembly isolated andcovered with a protection cover. For low temperatures, maintenance by self-regulated heating tapes. Version for use in hazardous zones: on request. |
