forged tubesheet for hear exchanger
Tubesheet/Perforated sheet/ metal mesh
The tubesheet is in contact with both fluids and so must have corrosion resistance allowances and have metalurgical and electrochemical properties appropriate for the fluids and velocities.
The tube hole pattern or "pitch" varies the distance from one tube to the other and angle of the tubes relative to each other and to the direction of flow. This allows the manipulation of fluid velocities and pressure drop, and provides the maximum amount of turbulance and tube surface contact for effective Heat Transfer.
1, for short hole tubesheet: the hole diameter range: Φ1.5mm---238mm
2, for deep hole tubesheet: the hole diameter range: Φ12mm---50mm ,
3, the max hole depth: 1100mm
4, the max tubesheet diameter: Φ8600mm
5, tubesheet material: SS, CS, Ti, copper, nickle base alloy, composite plate
6, Irregular hole and surfacing welding with strip electrode technology are available.
