Deep Drilling Hole Steel Tube Sheet for Heat Exchanger
Tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter, Round shape tube sheets are most widely used, but rectangular and square shapes are also occasionally adopted. We have contracted to custom make a variety of tube sheets for heat exchangers, boilers, pressure vessels used in many industries like nuclear power, petro-chemical, water-treatment, new energy, etc.
The bespoke tube plates we have produced feature as below:
* Tube sheet Material: Carbon steel, Alloy steel, Stainless steel, Duplex, Inconel, incolloy, Copper act.
* Large diameter capability up to 11900mm (11.9 meter)
* High precision, very narrow tolerance
* Deep boring possible up to 1100mm (1.1 meter)
* Complex hole shapes possible
* Multi machining processes possible
* Metal material can be carbon steel, stainless steel, and special alloys including Titanium.
Our cost effective precision metal machining for tube sheets and baffle plates include planing, cutting, milling, drilling, grinding, and any other metal processing techniques. Usually, for a round tube sheet or baffle not very thick, we can get the workpiece from cutting the metal sheet. Equipped with all series of world-class CNC machine tools like: Germany Schiess Double-gantry boring and milling machine, Italy PAMA large boring mill, Japan Mitsubishi horizontal boring and milling machine, China WZ large vertical turning center, We have the ability to complete a variety of tube sheets with tight tolerances in a few days after receiving the orders.
Cutting the raw material to obtain the rough rectangular plate.
CNC vertical lathe turning for pure zirconium tube sheet
For thin type tube plate, vertical drilling is suitable.
Chamfered holes make the tubes can be easily inserted.
Horizontal Deep Hole Drilling
In case of very thick tube sheet with deep holes, we choose horizontal deep hole drilling.
To increase the productivity, we apply the multi-spindle drilling to very huge tube sheets.
Being as a quality-oriented metal fabricator, we have equipped our factory with the best inspection tools. Like, ultrasonic tester (UT) for welding, our Leica AT901-LR laser tracker helps us to make sure the machine tools working in good order all the time that it can measure any large object within a sphere area of 80m in semi-diameter, the measurement accuracy is up to a micron. We also have different types of CMM test machine, our biggest Zeiss measuring machines can work on component up to 7000x4000x3000mm with an accuracy of up to 0.43 micron. Being as one-station-shop company, we can handle all the other related process like: heat treatment, sand blasting, painting, x-ray testing, etc.

Our Steel Machining Service:
We can supply Steel machining service, like cutting, welding, rolling, bending, forming, heat treatment service. such as the cutting of wear-resistant plates, high-strength plates, extra-thick plates, die steel and other kinds of steel plates, structural parts processing, transportation and distribution of the steel plates, to the factory. About Cutting Processing: thickness range is 3～600mm, width is below 4100mm. The geometrical dimensions and specification of the cutting parts are accurate with the characteristics of "high efficiency and high precision", and the quality of the steel plates is stable and reliable.
