The Qingdao Huashida steel elbow 3PE anti-corrosion production line is mainly used in various fields, such as industrial oil and gas transportation, water supply transportation, sewage transportation, and chemical transportation.

At least sixteen sets of Elbow pipe conveying structures have been set up, with Elbow pipes placed on the conveying structures. The rotating shaft of the driving mechanism is driven by a rotating motor to rotate the gear plate, and the rotational power is transmitted through the driving mechanism as the center. Adjust the height of the hanging rubber roller using the lifting device of the Elbow pipe conveying structure to adapt to the uniform center height of different pipe diameters.
3LPE Elbow Coating Machinery is for curve steel pipe blasting&coating and PE layer wrapping machinery. Anticorrosion form: epoxy powder + adhesive + PE tape.
