In pipeline anti-corrosion projects, rust removal from the inner wall has always been a major challenge in the construction industry, characterized by high difficulty, low efficiency and poor quality control. Traditional manual sanding or simple sandblasting methods are unable to evenly cover the inner wall of the pipeline, and the cleanliness does not reach the standard of Sa2.5 or above, which directly affects the adhesion and service life of the subsequent anti-corrosion coating. In response to this industry problem, Dongguan Meijun Automation Equipment Co., Ltd. has launched the MJ300-900 series - 1200-1600MM pipeline inner wall sandblasting cleaner. It adopts a dual-gun 360-degree rotation design and is combined with a high-temperature sintered pure boron carbide nozzle to achieve comprehensive sandblasting cleaning of the pipeline inner wall. One operation can reach the cleanliness standard of Sa2.5 to Sa3.0.

The various specifications and models of pipe inner wall sandblasters by Meijun are applicable to pipe diameters ranging from 20mm to 50mm, 300mm to 900mm, and even over 1200mm. They are used for rust removal, oxide layer cleaning, and pre-treatment before painting of inner walls of petrochemical pipelines, natural gas pipelines, municipal water supply and drainage pipelines, steel structure pipe columns, etc. The equipment has a compact structure and is easy to operate. It can be used in combination with different specifications of sandblasting machines and traction equipment, effectively improving construction efficiency and reducing labor costs. At the same time, the company also introduces self-return sand sandblasting machines and environmentally friendly water sand sandblasting tanks (high-pressure water sand blasters), which adopt water-sand-air mixed technology to achieve dust-free and far-reaching sandblasting operations, meeting the requirements of strict environmental protection in construction scenarios. Dongguan Meijun Automation Equipment Co., Ltd. (Meijun Sand Blasting Equipment) has provided system sandblasting solutions and supporting consumables for customers in fields such as anti-corrosion engineering, bridge manufacturing, shipbuilding, ship repair, steel structure treatment, and mechanical manufacturing, based on its over ten years of industry experience.
