Heating elements
have been particularly designed to carry out pre-heat, post-heat
and stress relieving treatment for joint welding operation. |

The assembly
process of heat insulating ceramic beads allows the production of
heating elements in a range of various dimensions which differs
from those listed and considered standard. |

(RUN) heating elements two kinds of insulation can be used:
- (A) ALUMINIUM
- (S) STEATITE

SHELL HEATING ELEMENTS |

Shell heating elements are realized on a stainless steel
support, closed by a lever locking system, and they arecomplete of a heat insulation made of silicate fiber covered
by “Siltex” fabric.
Shell heating elements are particularly suitable for the treatment
of great quantities of pipes with the same diameter,
being quickly and easily positionable by a single person. |
