In the field of tube expansion in heat exchangers and boilers, Pipe Ltd recommend the use of rolling equipment with electronic torque control. The MRS combines high quality, sturdiness and reliability with low cost; it suits all kinds of applications in heavy metalworkings, refineries, power plants, shipyards and sugar mills.
The main characteristics of the MRS system are the following:
Great versatility: It is possible to equip the unit with rolling motors having different speeds and powers according to the jobs to be executed.
Extremely simple to use: It does not require skilled personel.
Simple and tested electronics
Low purchasing price and low maintainence requirements
Precision and high work reliability
The MRS system uses the electronic control unit F90 V3 which permits the automatic compensation of tolerances which are always found in the diameter of tubesheet holes as well as in the tube gauge.
The calibration of the control unit carried out during suitable preliminary tests making it possible to have a sure and uniform tightness of all the tubes at the working pressure of the thermal exchange units.
The main characteristics are:
• Setting of expansion values
• Simple use
• Programmable continuous cycle
• Repeatability tolerance lower than 4%
• Rolling of tubes from 6mm to 120mm according to the rolling motor utilized
The MRS system is available with a range of rolling motors, including portable models and models for use with a trolley or a simple frame unit depending on the application.
