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
