Cleaning of inner wall of steel pipe

I. Overview

The mobile steel pipe inner wall shot blasting machine is a specialized equipment designed by combining the technology principles of roadway shot blasting machines and tailoring them to the specific needs of cleaning steel pipe inner walls. It thoroughly cleans the inner walls of steel pipes by projecting high-speed shot or steel pellets, removing impurities such as oxide scale, rust, weld slag, enhancing the cleanliness and roughness of the pipe's inner surface, and providing an excellent substrate for subsequent coating or anti-corrosion treatments.

II. Working Principle

The working principle of the mobile steel pipe inner wall shot blasting machine is similar to that of a roadway shot blasting machine but optimized for the unique structure of steel pipe inner walls. The equipment drives the shot blasting wheel to rotate at high speed through an electric motor or hydraulic motor, generating centrifugal force and wind power to accelerate and project the shot or steel pellets onto the inner wall of the steel pipe. During the impact on the inner wall, the shot removes impurities through冲击力 and friction, simultaneously increasing the roughness of the inner wall. The cleaned shot and dust are processed through a recovery system, enabling the recycling of shot and effective dust collection.

III. Features and Advantages

• Efficient Cleaning: Quickly and thoroughly cleans the inner wall of steel pipes, improving cleaning efficiency.
• High Adaptability: Suitable for cleaning steel pipes of different diameters and lengths, with a wide range of applications.
• Excellent Inner Wall Treatment: The cleaned inner wall of the steel pipe has high cleanliness and uniform roughness, which is beneficial for coating adhesion and anti-corrosion treatment.
• Environmentally Friendly and Energy-saving: Adopts a shot recycling system, reducing material consumption and environmental pollution while lowering energy consumption.
• Easy Maintenance: The equipment structure is designed reasonably, making it easy to maintain and reducing maintenance costs.
• Simple Operation: Equipped with an advanced control system, it is easy to operate and master.

IV. Application Scope

The mobile steel pipe inner wall shot blasting machine is widely used in steel pipe production, petrochemical, urban central heating, water supply and drainage, and other industries for steel pipe inner wall cleaning tasks. It can effectively improve the quality and service life of steel pipe products, reduce maintenance costs, and is an ideal choice for steel pipe inner wall cleaning.
