The steel pipe inner wall shot blasting cleaning machine is a equipment specially used to clean the surface of the steel pipe inner wall, rust layer, welding slag and other debris. It impacts and rubs the inner wall of the steel pipe through high-speed projectile flow to achieve the purpose of cleaning and strengthening. The following is a detailed introduction from the aspects of equipment principles, technical characteristics, application fields and advantages: 1. Equipment principle The working principle of the inner wall shot blasting cleaning machine of steel pipe is based on shot blasting technology. The projectile is accelerated by a high-speed rotating shot blasting device, and the projectile is sprayed to the inner wall of the steel pipe through a specific conveying device. The projectile impacts the inner wall of the steel pipe at a certain speed and angle, removing impurities such as oxide scale, rust layer, welding slag, etc. on the surface, and at the same time, causing microplastic deformation on the surface of the inner wall of the steel pipe to improve its fatigue strength and corrosion resistance. The cleaned projectiles and impurities are separated by the recycling system, and the projectiles can be recycled. 2. Technical features: Efficient cleaning. High-speed projectile flow uses all-round impact on the inner wall of the steel pipe. It has high cleaning efficiency and can completely remove the oxide scale, rust layer and welding slag on the inner wall surface. Strong adaptability can adjust the parameters of the shot blaster according to the diameter, length and wall thickness of the steel pipe, such as shot blasting speed, flow rate and angle, to ensure the consistency of the cleaning effect. For steel pipes of different pipe diameters, the equipment can be equipped with an adjustable sealing device to prevent projectile leakage. Equipment with high degree of automation is usually equipped with PLC control systems to achieve automated operations. Processes including steel pipe conveying, shot blasting cleaning, projectile recycling and separation can be automatically completed to reduce manual intervention and improve production efficiency. Environmentally friendly and energy-saving equipment adopts a closed design and is equipped with an efficient dust removal system, which can effectively collect dust and impurities generated during the cleaning process and reduce environmental pollution. At the same time, the projectile recycling system reduces material consumption and saves costs. The equipment has a compact structure and a reasonable design, small footprint, and is suitable for installation and use in limited space. At the same time, the equipment is easy to maintain and maintain, reducing operating costs. 3. Application fields: Steel pipe inner wall shot blasting cleaning machines are widely used in petroleum, chemical industry, natural gas, urban heating, water supply and drainage industries, and are mainly used for the inner wall cleaning of the following steel pipes: Oil and natural gas transportation pipelines: Remove the oxide scale and rust layer of the inner wall, improve the corrosion resistance of the pipeline, and extend the service life. Urban heating and drainage pipes: Clean the welding slag and impurities on the inner wall to ensure the flowability and safety of the pipes. Structural steel pipe: used to clean the inner walls of structural steel pipes such as buildings and bridges, improve the surface quality and adhesion of steel pipes, and facilitate subsequent anti-corrosion treatment. 4. Equipment advantages to improve the quality of steel pipes. By cleaning the scale, rust layer and welding slag on the inner wall of the steel pipe, the surface quality of the steel pipe can be significantly improved and its corrosion resistance and mechanical strength can be enhanced. The surface of the inner wall of the steel pipe after extended service life is smooth, reducing the corrosion and wear of the medium on the inner wall of the steel pipe, and extending the service life of the steel pipe. Reduce maintenance costs Efficient cleaning and automated operations of equipment reduce labor costs and maintenance time, while projectile recycling systems reduce material consumption and further reduce operating costs. Environmentally friendly and compliant equipment is equipped with efficient dust removal systems.
