Home » Formed Elements |
We can form a straight element into any design that you might want, to your exact specification. With superb service and a fast turn around, make sure you use TPFay whenever you need a formed element replacing.
Sheathed Elements, Forming Options
Custom formations to your requirements are our specialty. However here are some examples of regular patterns.
Sheath Materials
-
lncoloy sheath temperatures to 870°c
-
Stainless steel sheath temperatures to 650°c
-
Steel sheath temperatures to 400°c
-
Copper sheath temperatures to 175°c

Features |
|
Precision wound nickel-chromium resistance wire distributes heat evenly to the sheath for optimum heater performance. |
|
Special sealing techniques developed over 25 years of testing are available to prevent moisture absorption over an extended period. This maintains good insulation and dielectric properties over an acceptable timescale. |
|
MgO insulation filled sheath maximises dielectric strength, heat transfer and life. |
|
Sheath materials include: lncoloy, copper, mild steel, 316 stainless steel 304 stainless steel and titanium. |
|
Multiple bend formations allow forming the heating element to the application. Spirals, compound bends and multi-axis and multi-plane configurations. |
|
Resistance wire fusion welded to the terminal pin for a stronger, positive electrical connection. |
|
Ceramic insulators isolate terminations from metal sheaths. |
|
Termination, mounting and moisture seal options available |
|
.The tubular heating element lends itself ideally to the entire range of immersion, solids and air heating applications. |

Insulation Resistance Values
The dielectric used in the production of all mineral insulated heating elements magnesium oxide is hydroscopic. On completion, the heating elements will be sealed against ingress of moisture and while we set our pass/fail level for inspection testing at 100 megohms in practice, elements leaving the works will be infinity.
The seal we employ is a silicone-based fluid and does not give a totally hermetic seal. Over extended period in stock the I.R. value will reduce gradually, if elements fall below 1 megohm, we recommend that the element should be dried at a temperature of 250 to 300°c for 3 to 4 hours before use. This will remove the moisture contents of the insulant and the I.R. value will quickly restore to previous level.
All products must be kept in a clean dry area and protected from dust and dampness in order to ensure the correct operation of this equipment.
