Heat exchanger has grown bigger and bigger in many industries such as oil, chemical, food processing etc., in order to achieve high efficiency and reduce energy consuming. Tube plate, as an important parts of the heat exchanger, to house the heat exchanging tubes, are required to be flat enough and high precision of hole drilling.
Here attached is one of large heat exchanger tube plates a large fertilizer maker asked us to produce. It is made of metal material 20MnMo, with diameter 3692mm, 5723 holes on the plates and the hole depth is up to 638mm.
Our large CNC machining service is first class. We are competent to do this job because we have 27 off multi drilling CNC machines and 11 off deep hole drilling CNC machines, among which the largest CNC drilling machine produced by Innse Berardi can drill holes as deep as 1.1m.
