The main advantages of steel shot blasting rust removing machine:

A wider range of diameters, operations, 48mm-1400mm can all kinds of steel pipe rust.

In two, rust removing effect is good, can reach the national standard SR / TQ414-98 SA2.5 level above.

In three, no environmental pollution, derusting machine running, small noise, no environment pollution, no leakage of steel.

In four, for steel simple, disposable sand can be used for a long time.

In five, small volume, simple installation, flexible handling.

In six, low price

Steel pipe wall shot blasting process

The process uses the high-speed rotation of the impeller device with move pills and to accelerate while throwing, hit the steel tube wall, removal of the surface oxidation skin, rust and welding slag, thereby removing the welding stress, increasing the steel pipe surface anchor pattern depth, thereby enhancing the pipe surface adhesion, greatly improving the polyurethane and steel pipe the adhesive strength, so that the insulation pipe steel pipe and heat insulation layer are combined into one.
