2. Technological flow:
Steel pipe Load-up online---->External shot blasting ----> dust collector---->internal blow out---->lifting transport pipe trolley---->transport to chuck----> chuck hoist cylinder----> alignment chuck center---->mechanical arm station adjust---->chuck hydraulic clamping---->chuck guard at both ends----> carrier pipe servo transport---->IF heating----> PU foam spraying----> pipe load down line----> transport pipe ----> PE film wrapping----> water cooling---->cutting down pipeline---->trim end of pipe---->printing mark&loading down finished pipe---->sealing end of pipe
3.Advantages of Huashida stand
The steel pipe stand can be installed within an error range of ± 80mm of the user's ground foundation. The height of the stand is adjusted by anchor mounting bolts. When installing the stand, a slope of 5 ‰ is reserved, making it easy to roll large pipe diameters. Reduce labor intensity. After the installation of the platform frame, the foundation of the platform frame shall undergo secondary grouting treatment, with a neat and generous appearance
4. Advantages of Qingdao Huashida brand steel pipe conveying system
Unified adjustment of opening and closing, and unified adjustment of angle.
The separate power drive of each group of wheels expands the spiral angle of the conveyor, with a transmission angle of up to 30 degrees. The transmission speed is adjustable from 0 to 6 meters per min.
Solid core wide face tires are used, with a bearing capacity of 2.5 tons for a single wheel. They are press fit tires, without degumming and cracking. The thickness of the adhesive layer is greater than 85mm, and the transmission is stable and reliable, providing a safety guarantee for the long-term operation of the equipment.
