Product Description
Wind Power Transition Flange Of Wind Power Accessories For Wind
Turbine Tower Connection
There are different kinds of wind turbine tower parts to support wind turbine tower construction and wind turbine tower further maintenance. As a professional wind turbine tower manufacturer, Anyang
Machinery provides complete wind turbine tower solution with all
kinds of wind turbine tower spare parts, such as onshore wind
turbine tower foundation components and wind turbine tower
internals.
For onshore wind turbine towers, the foundation is one of the main parts for wind turbine tower.
We have seen many wind turbine tower collapse accidents happens,
and the wind tower foundation have been totally uprooted.
Therefore, high strength wind turbine tower foundation is very important for wind turbine tower stiffness.
Normally, a complete steel wind tower is about a hundred meters high. In order to transport the wind
turbine tower onsite, the wind tower manufacturers makes several
wind tower sections, and assemble them together onsite. Therefore,
in wind turbine tower manufacture process,there are flanges on the ends of each wind tower section. Wind tower flanges are the connecting parts of wind turbine towers. It is a big ring
with multiple holes equally distribute on it.
Wind Tower Flanges
Materials: Q345C, Q345D, Q345E or other standard carbon steel
Standard: ANSI, JIS, DIN, etc
Dimension: customized
Connection Method: Welded
Drachma Materials provides complete customized wind turbine tower solutions, the dimension of wind turbine tower (include wind tower flanges),
foundation structure, and wind turbine tower internals will be
manufactured fully based on customers’ requirements. If you have
any questions about wind turbine tower anchor cages and wind tower flanges, please feel free to contact us.

Company Profile
DRACHMA (ZHANGJIAGANG) MATERIAL CO.LTD has two main production
plants. Zhangjiagang plant is responsible for the rough forming of
workpieces, mainly forging process; While Hangzhou plant is mainly
responsible for precision machining, welding and inspection of
products. We implement this layout mainly to use the industrial
advantages of each region to achieve maximum economic benefits.
Traditional processing enterprises often do not have such ability,
the lack of blank forming ability is unable to achieve the optimal
use of materials, resulting in excessive processing allowance, long
cycle, high cost. Zhangjiagang is located in the southern jiangsu
province, which has the strongest forging capacity in China. It has
a good supporting industry and can realize the diversified
production of forging and pressing blanks. Thanks to this, the
product cycle of our company is faster, the cost performance is
higher, and the forging products have better mechanical properties
than the products directly processed by rod or plate.
In addition, our company has strong welding ability, which can weld
and assemble parts to achieve system delivery. We adopt the mode of
automatic robot welding and manual precision welding to achieve
flexibility and high quality.
