Welded shell & plateheat exchangers

Features of welded shell &plateheat exchangers (SPHE) of ESKM

• decreased dimensions at similar performance (in comparison with shell&tube heat exchangers)
• thermal and hydraulic stresses in round plates are distributed more equal than in rectangular ones, that reduces the risk of cracking
• low weight
• absence of sealing between heat exchange plates
• design pressure up to 150 bar (overpressure)
• high resistance to cyclic loads
• high coefficient of heat transfer
• dismantling of the structure
• the use of laser welding during manufacturing of plates packages
• welded seams with large contact surface, simultaneously the heat supplied during welding is reduced
• a smaller volume of weld pool prevents the formation of shrinkage holes and pores during crystallization
• along with high rate of heat exchange the turbulent flow leads to more expressed effect of self-purification and contributes to minimization of temperature

Heat exchangers plates form parallel channels through which hot and cold mediums alternately pass. There is a heat transfer from hot to cold medium through the walls formed by plates of channels.

Warmed up and heated mediums pass through the plates cavity or shell cavity. Vessels can be all-welded or opened.

Opened vessels on one side allow to perform inspection from the shell side.Opened on the both sides two packages are intended for large capacities or for several circuits.

Shell and plate heat exchangers of ESKM can be installed horizontally or vertically in accordance with the requirements of technology or for optimization of the geometry for connections.
