    Wind power flange is also called wind tower flange, wind tower flange is the key of wind power tower connecting piece, a supporting piece and stress, are important components of wind power generation equipment manufacturing, to have very strict requirements.

    The work environment and life:

    The main reason is the flange to the use of more than 20 years in the wild and reliable, wind alternating load withstand all kinds of extreme weather and complex, long in the 50 ~ 80m height under tensile, bending and shear force, if the product is not anti low temperature impact of superior performance, enterprises do not have stable quality assurance ability is very difficult to imagine, all for the wind turbine will be long-term and stable operation of thedisaster caused There's no telling.


    Flange the main material for S355J2G3, 50Mn, AISI4130 and so on.

    The characteristics of:

    Watch tower flange on one week full bolt from the shape used to link the tower.
