PRODUCT

Hangao polishing machine is used for surface treatment of metal pipe,these treatments include polishing.

This system is mainly applied to rectify and track the stainless steel seam tube in the TIG welding process automatically.

In order to improve the production efficiency, and can get good weld quality.

The intelligent control system of the new precision industrial welded pipe production line records and saves the data of the production line.

Argon arc welding is tungsten inert gas arc welding, refers to the industrial tungsten or active tungsten as the non-melting electrode.

Plasma arc is ionized ion gas to generate high-temperature ion flow.

Double cathode welding technology makes a significant process in stainless steel pipe welding technology.

Device can adjust the position of the welding bead,but will not change the pipe diameter.

Ink-jet machine is controlled by software and mark the identification on the product non-contact.

When there is defects or cracks on the surface of the pipe,the magnetic flux that go through the probe coil will change.

Hangao inside polishing machine is used for internal treatment of metal pipe.

Heat-exchanger pipe making machine of Seko Machinery (tube mill )is equipped with uncoiler.

HGL series energy-saving bright annealing machine is designed for synchronous inline bright heat-treatment of the pipe. 

Process Flow
Heat preservation bright annealing furnace tube heat treating machineperature lower than 100 °C under the protection of hydrogen.The heating power supply of the intermediate ferquency induction is the newest DSP+IGBT structure.With DSP digital control system,there are self protection and self diagnostic functions.With small volume,it heats pipes rapidly and efficiently with energy-saving and low-waste features.The especially developed inducer designed according to the features of stainless steel can save 15%-20% energy in contrast of other products of the same class.Using hydrongen as of gas every minute.

Stainless steel coil pipe has replaced seamless steel pipe in some fields gradually for its simple productive technology.

Petrochemical pipe production line is equipped with uncoiler,forming&welding machine.

This production line uses W molding to weld the industrial welded pipes required by customers with carbon dioxide laser welding.

Big diameter welded pipe black annealing machine is the special machine for heat the steel pipe to solution temperature and then cool it to room temperature.

Petrochemical pipe production line is equipped with uncoiler,forming&welding machine.
