ASTM A179 Heat Exchanger Tube Sheet Steel Pipe Flange Cover

The accuracy of tubesheet processing,

especially the pipe hole spacing and pipe diameter tolerance,

perpendicularity and finish, greatly affect the assembly and

service performance of the chemical equipment listed above.

With the large-scale of chemical equipment and power stations,

the diameter of tubesheet is becoming larger and larger.

Tubesheet with diameter of 4m-5m is very common.

Large tubesheet is characterized by large number of tube holes, dense, small diameter,

deep, high precision and finish requirements.

Purpose:

1.in tubular heat exchanger, boiler,

2.in pressure vessel, steam turbine,

3.large central air conditioning and other industries.
