Traçage par tube à effet de peau
Skin effect trace heating
TTEP
www.chromalox.co.uk - www.chromalox.fr
• Pour maintien en température jusqu'à 150°C
• Traçage de pipes de grandes longueurs
(jusqu'à 25 km) avec un seul point d'alimentation
• Technologie applicable aux tuyauteries arériennes,
enterrées, ou immergées.
• Tension d'alimentation jusqu'à 3500VAC
• Grande robustesse (câble à isolant particulièrement
résistant à la chaleur, à la corrosion, au déchirement,
et à l'effet corona / protection mécanique par tube acier)
• Absence de maintenance (intervention éventuelle
sans décalorifugeage)
• Absence de tension résiduelle en surface de
tube traceur et du pipe / Ensemble mis à la terre /
Aucune affectation des protections cathodiques
• Faible écart de température entre le câble,
le tube traceur, et le pipe.
• For temperature maintenance up to 150°C
• Heat tracing very long pipes (up to 25 km) with only
1 supply connection
• Technology applicable to elevated, buried, or
immersed pipes
• Voltage up 3500 VAC
• High robustness (insulation jacket is heat, corrosion,
rending, and corona effect resistant / cables protected
by steel tube)
• No maintenance and possible exchange of cable
without removing of insulation
• No residual voltage on external face of tube and pipe /
Earth connected / No effect on cathodic protective
device
• Low temperature gap betwen cable, tube, and pipe
• La tuyauterie à maintenir en température est équipée
d'un ou plusieurs tubes acier de petit diamètre, soudé(s)
ou cerclé(s) sur celle-ci, suivant une ou plusieurs
génératrices.
• Un câble non chauffant, cheminant à l'intérieur du petit
tube, amène la tension jusqu'à l'extrémité du pipe.
• Le retour du courant s'effectue alors par le petit tube,
mais exclusivement sur sa face interne, et suivant
une épaisseur définie par la loi de Kelvin et Maxwell
• La face externe, et donc l'ensemble du pipe reste
exempt de toute tension résiduelle, et peu être
raccordé à la terre.
• L'échauffement du petit tube s'effectue par effet Joule,
dans la fine épaisseur interne concernée et se transmet
par conduction au gros pipe dont il assure le maintien
en température (liaison par soudure, ou par cerclage
et ciment conducteur)
• The pipe being maintained at temperature is fitted with
one or several small steel tubes set on pipe generants
by welding or by rings
• A non heating cable, set inside the tube, conduct the
voltage up to the end of the pipe
• The return of current goes by the small tube, but only
through an internal thickness defined by the laws of
Kelvin and Maxwell
• The internal face, and so, the pipe itself, remains
without residual voltage and can be earth connected
• The heating of the small tube is generated by Joules
effect in its thin internal thickness concerned, and
transfers it to the pipe by conduction (welding /
rings / thermal cement)
