L415 material 3 PE anticorrosive spiral pipe main standard polyethylene and high density polyethylene, vicat softening point was not less than 110 ℃;The thickness of the outer anticorrosive coating is determined according to the German standard DIN30670, which is mainly low and medium density polyethylene, greatly improving the impact strength of 3PE anticorrosive coating.3PE anticorrosion is a commonly used anticorrosion method *, in addition to 2PE, 2PP,3PP, their manufacturing process is similar, but the raw materials are not the same, this kind of anticorrosion is characterized by simple manufacturing process, good anticorrosion effect, low price, is generally recognized as the pipeline manufacturing anticorrosion method


For example, a water-cooling system installed on the output bench to speed up cooling allows for the use of low alloy composition to achieve special strength grades and low temperature toughness, thus improving the weldability of steel.But this kind of system basically does not have in the steel plate factory.
