How to machining tubesheet in special materials

The tubesheet used for class III and IV pressure vessels needs relatively high precision. The traditional hole processing methods are bench marking and rocker drilling.

With the large-scale of chemical vessels, the diameter of tubesheet is also increasing, and the thickness is also gradually thickened. NC technology is also introduced into tubesheet processing. NC drilling machine is widely used to guide holes and cooperate with rocker arm drilling for hole processing. Using machining center to do high-efficiency and high-precision hole machining has gradually been accepted by some large enterprises.

The demand for large and heavy tubesheet in the fields of nuclear power, seawater desalination and central air conditioning heat exchanger is showing an increasing trend.
