Description
technical field:
The utility model relates to a kind of servicing unit for automatically grinding helix tube weld reinforcement, belongs to Mechanical Manufacturing and Automation control technology field.
background technology:
Steel pipe is the universal metal material of conveying fluid, and it is adopted in a large number in the media such as transferring oil, gas, water.Because metal material is in use easily subject to the impact of external environment condition and interior media, and reduction of service life.In order to extend the service time of steel pipe, conventional method is: carry out anti-corrosion protection process to its outside or inside.At present, be exactly that three PE pipelines are outer anticorrosion in the technique that pipeline corrosion protection industry is maximum to steel pipe corrosion-proof in the world.
When producing helix tube 3PE/3PP and being anticorrosion, in coating pipeline process, because weld seam is often higher than pipe face 2mm-2.5mm, even higher, to cause above weld seam coating layer thickness can thinning 20%-30%, cause even weld seam position coating cracking, causing useless pipe.Qualification rate is declined, causes waste of raw materials.
According to the development of current pipeline corrosion protection industry, all perform international high standard/tight requirement.There are many customer requirement commissures not allow thinning in process of production, in the face of the order that this high standard requires, welding seam coating thickness ensured, whole pipe coating can only be added thick 2.0-2.5mm at present, even, cause a large amount of wastage of material, directly affects anticorrosion benefit.Even, some order also has requirement to coating layer thickness bound, more just adds anticorrosion difficulty.
