If the welded structures such as tanks, pipes, nests of boiler tubes, manifolds and so on,will be affected by high pressure or stress, their welded parts require a further drawing in order to get a stress relieving and a homogenisation in the structure.

If the parts are small and transportable, this process can be carried out in a furnace but this is impossible for large parts and for parts already included in large plants (power plants, chemical plants, pipelines etc.). In these cases our electric generators are necessary in order to heat the required parts through resistance heating elements or directly using induced magnetic fields ( by coils).

For these purposesParmaprogetti manufactures the TS150 generators, and MI induction module. Equipped with a complete range of accessories. They can meet all the requirements for these operations in a Fast, Reliable and Cost-effective way.

MI induction module

Module for transforming any of the outputs of the TS 150 generators in to a 25 KW variable frequency induction output. The module, therefore, adapts to the load.
Dimension with wheel : L650, W650, H760 mm.
Weigth: 300 Kg.

RESISTANCES

For resistances heating the following elements are avaible:

Flexible pannel resistances, alumina insulated, with camlock connectors, power 3.6KW / 80V / 45A in various form
Flexible one-wire resistances, power 3.6KW / 80V / 45A, L 7m, steatite insulated, with camlock connectors
Stiff one-wire resistances, power 5.3KW / 80V/ 66A, L 8m, steatite insulated, with eyelet connectors
special fitting on erequest

COILS for induction heat treatment

Flexible, ceramic fibre insulated coils are used for general use. They have a eyelet terminal connection and are air cooled; standard type with length 10 m, sect 200 mm² , max 800 A. Stiff or flexible coils, water cooled or for special applications can be made on request.

THERMOCOUPLES

All "K" type thermocouples are compatible with our generators. We however recommend:

Wire thermocouples to be welded with capacitive discharge
Stiff thermocouples to be welded
Contact thermocouples for quick checks

INSULATING MATERIALS

For resistance heat treatment we recommend: ceramic fibre, thickness 1", density 128 Kg/m³ wrapped in inconel net
For induction heat tretment we recommend the same product without net, or alternatively ceramic fibre in fabric, thickness 3 mm, density 1.5 Kg/m.

HTS
Heat treatment system

HTS is a programme, exclusive to Parmaprogetti, by means of which the required heat cycles may be drawn with one finger on the control. Similarly, data can be recalled, stored, erased and displayed. The HTS programme contains all our experience in heat treatment e.g.:the programme automatically calculates the PID (Proportional-Integral-Derivative) and foresees whether the treatment will give good results; through thermocouple and electrical load anomalies. In case of a main supply failure, the program goes into standby and when the power returns it decides, on the basis of the time elapsed, the next step to take.
