Product Description

We have rich experience in machining various heat exchanger tube sheets, baffles, special tube sheets for power stations, etc. The materials we produce include duplex stainless steel, titanium alloy, forged carbon steel and so on. We are also able to manufacture and process according to specified standards such as ASME. Our company is equipped with full series of advanced tube sheet processing equipment, such as multi-hole drilling, deep hole drilling, and we also have semi-automatic chamfering processing equipment, which can shorten the construction period.

In order to ensure that the quality perfectly meets the requirements, all the tube sheets we produce need to go through the first inspection process after machining process finished to ensure that the dimensions, hole accuracy and other dimensions are up to standard. Besides, we will arrange special personnel to inspect all holes with a pass-and-stop gauge. For products with stricter requirements, we will use CMM testing equipment to further test all parameters and provide relative inspection reports to the customer.

We have rich experience in manufacturing of large machined weldment or iron castings and forgings for industrial equipment like foring press, rolling mill, grinder, water conservancy and hydropower equipment, chemical equipment, mining machinery and equipment and all kinds of non-standard equipment with single weight up to 200 tons. Our products had been widely used in steel rolling, chemical, mining, hydropower, metallurgy and other industries.
Our company was founded in 1999, our factory currently has more than 1600 employees, covering an area of over 1,00,000 square meters, which has four sections: Equipment Assembly Dept., Metal Fabrication Dept, Precision CNC Machining Dept, Casting and Forging Dept.We provide full service fabricating service , from material supply, cutting and forming, rough machining, finish machining, welding assembly, and surface treatment, to the final packaging and transportation.Being as a large capacity machine shop, we have equipped a series of multiple CNC machines for both vertical and horizontal manufacture enable us to machine complex components of a large array of sizes. Our machining workshop has advanced 30-meter and 26-meter double gantry machining centers, which can basically process the precision milling and boring requirements of even the largest workpieces in various industries all around the globe.

We have a series of imported CNC Machining equipment, including large gantry machining center, horizontal boring and milling machine, turning and milling center, large vertical lathe machining center, heavy horizontal lathe machining center, dmulti-hole drilling deep hole drilling and other machining equipment facilities.Our processing capabilities are as follows:
