Steel pipe inner and outer shot blasting machine use the technical of shot blasting and sandblasting to cleaning the pipes. It not only can remove the oxide scale or rust on the inner and outer surface of steel pipes, but also can eliminate the stress improve the fatigue strength of the steel pipe and reach the specified roughness and hardness. And finally achieve the purpose of improving the surface and internal quality of the entire work. This type of machine is particularly suitable for oil pipeline anti-corrosion projects.
What is steel pipe inner and outer shot blasting machine?
Steel pipe inner and outer shot blasting machine is suitable for the shot blasting of the outer wall of the steel pipe and the inner wall of the steel pipe to remove the rust, oxide scale and dirt on the surface of the steel pipe. Fatigue performance to achieve the purpose of improving the surface and internal quality of steel pipes and ultimately improve the corrosion resistance of mechanical products and metal profiles and improve the fatigue resistance of steel and extend its service life. Optimize the surface process of steel pipes to achieve the purpose of complete cleaning.
What is the application field of steel pipe inner and outer shot blasting machine?
Steel pipe inner and outer shot blasting machine is suitable for surface cleaning of various diameter steel pipe inner and outer walls and is widely used in pipeline anti-corrosion, petrochemical, steel, central heating, water supply and drainage industries.
How to extend steel pipe inner and outer shot blasting machine service life?
The abrasive splash problem of steel pipe inner and outer shot blasting machine is a common problem of all shot blasting machines. QGMA company has also done a lot of research and experiments on this. Although it can not be said that it has been solved 100%, it has been greatly improved. The problem of abrasive splash is controlled within a small range, so that there is basically no impact on the daily production and maintenance of customers.
QGMA Machinery hang rubber curtains and rubber spring plates on the inner side of the steel pipe inner and outer shot blasting machine’s chamber, which effectively reduces the situation of abrasive splash. If the customer’s site area allows, the length of the chamber should be appropriately increased. Although this method will increase the production cost of the steel pipe inner and outer shot blasting machine, we think it is worth it. This will fundamentally solve the problem of abrasive splash and will not increase the later use cost. We put the third plate on the gap, which between the two steel plate. This design can avoid the abrasive hit the gap and increase the service life of the blasting chamber and the materials used are all thick and wear-resistant special guard plates. So as to prevent flying sand from the gaps after the guard plates are worn.
Generally, the V-shaped inclined roller conveyor is used for pipelines whose outer diameter is less than 300mm (inclusive). The pipes advances on the V-shaped roller table while rotating around itself. For pipes with an outer diameter of more than 300mm, solid tires are generally used as the drive roller. According to different size of the pipes, universal joint transmission or independent driving of each tire group can be adopted.
