PE pipe flanging remover adopts adjustable pulley shaft design, which increases the use range of the edger. If the bottom pulley is lost, the edger can be used normally without damaging the outer wall of the pipe. This flanging remover has a bottom pulley design, and 4 pulleys at the bottom of the edger can make construction faster and easier, and also protect the outer wall of the pipe. This flanging remover uses an aluminum alloy body design to reduce the overall weight of the edger and reduce the labor intensity. This flanging remover, the bottom pulley deepens the thread design, supports the center screw of the bottom pulley. Its tapping depth reaches 8mm, which better fixes the pulley. Even if the edger falls directly to the ground or is thrown, the pulley is harder to lose. This flanging remover has a special alloy blade. The edge edge of the edger is made of imported steel from Japan. It has the material, and has undergone destructive testing, and its rust resistance, strength and toughness properties.
