Titanium Tubesheet for Heat Exchanger
Product Information
Tubesheet is a circular plate drilled with holes of the same diameter as the pipe. It is used for the heat exchanger to fix the pipe. An accessory that accomplishes this by passing a pipe through and welding it in place.
The precision of tubesheet processing, especially the tolerance of tube hole spacing and diameter, verticality and finish, have a great impact on the assembly and performance of the above-mentioned chemical equipment.
With the enlargement of chemical equipment and power stations, the diameter of tubesheets has become larger and larger. Tubesheet with a diameter of 4m-5m is very common. The characteristics of large tubesheet are many tube holes, compactness, small hole diameter, deepness, high precision, and high finish requirements.
