Shipyard's hull surface sandblasting cleaning, and secondary surface sandblasting and rust removal cleaning of ship hulls. As well as sandblasting and descaling cleaning of pretreatment line of steel plates used in manufacturing hulls.

The steel sections and steel plate accessories applied to steel structures are blasted and descaled using pass-through shot blasting machines. Only the cleanliness and roughness suitable for the surface requirements of the workpiece is conducive to the next process of painting, spraying, etc. So for customers must use high-quality cost-effective steel shot to reduce production costs and reduce the loss of steel shot in sandblasting cleaning.

Casting parts in the casting process on the surface and its internal structure surface residues of a lot of casting sand and oxide layer, are required to blast machine to clean up. Forgings in the heat treatment process produces a layer of oxide skin layer, due to the casting itself hardness requirements is very high. So it must use high strength and high wear-resistant shot or sand to achieve the required effect.

Containers for a long time in the ocean transportation and wet and high salt environment, for paint and corrosion has high requirements. In the container surface shot blasting process, the roughness and cleanliness of the box surface cleaning is more stringent requirements, so in the shot blasting to choose the right steel shot or steel sand. Only the high quality and high wear-resistant shot can meet the specified requirements.

Some machinery and equipment are subject to strict sandblasting and sand cleaning before assembly. In order to ensure the surface requirements of the equipment before painting.

Before the whole car is equipped, almost all the frame body, and also and some of its parts, should be sandblasted and rust-cleaned. The following are some examples in use.

Only a good treatment of the oxidation layer on the outer surface of the pipe can ensure the quality requirements of the anti-corrosion layer of the pipe. The selection of suitable shot and sand materials has a great relationship to the roughness and cleanliness of the pipeline surface and adhesion.

Mainly for large and irregular object parts of the surface rust removal cleaning. Many mechanical equipment, castings and irregular object parts, can not be cleaned by a fixed shot blasting machine, only through manual sandblasting room to complete sandblasting, rust removal cleaning. For example, the surface of the ship hull, wind power tower, large steel structure parts, large castings sandblasting cleaning.

Spring, steel plate and other such products themselves require high hardness and strict quality requirements, for the surface of the sandblasting, cleaning requirements are even more stringent. According to the surface requirements of roughness, cleanliness, to use high hardness, high quality second quenching steel shot, steel sand, in order to achieve the required effect
