Burrs are an inevitable byproduct in metalworking, regardless of the sophistication of the machinery employed. Their formation is primarily attributed to the material's plastic deformation and the accumulation of excessive metal shavings at the edges of the workpiece, particularly in materials with high ductility or toughness, which are more susceptible to burring.
Burrs can be categorized into types such as flash burrs, sharp corner burrs, and spatters, which are unwanted metal projections that deviate from the product's design specifications. Given the current state of technology, there is no foolproof way to prevent their formation during production, necessitating post-processing efforts by engineers to meet product design specifications. A variety of deburring techniques and equipment have been developed to address this issue for different steel pipe products.
Deburring Techniques for ERW Welded Pipes:
ERW (Electric Resistance Welded) pipes may develop burrs or sharp edges during the welding process. Deburring is crucial for safety, aesthetics, and to ensure compliance with industry standards. Here are the nine most prevalent deburring methods used by ERW pipe manufacturers:
Manual Deburring
Manual deburring can be performed using tools like angle grinders, files, or abrasive pads, suitable for small-scale operations or specific burred areas.
Mechanical Deburring
Mechanical deburring machines automate the deburring process, often using brushes, rollers, or other abrasive tools to smooth pipe edges.
Abrasive Belt Deburring
Abrasive belts, either handheld or machine-mounted, are used to grind away burrs, offering a more controlled and consistent deburring process.
Rotary Deburring
Rotary deburring tools are designed to remove burrs from both the internal and external surfaces of pipes, adjustable for different pipe sizes and suitable for production lines.
Chemical Deburring
Chemical deburring uses specific solutions to dissolve or break down burrs without affecting the underlying metal, suitable for certain applications and materials.
Water Jet Deburring
High-pressure water jets can remove burrs from pipes, effective on softer materials and scalable for large-scale production.
Tumbling or Vibratory Finishing
Tumbling or vibratory finishing machines use abrasive media to deburr large quantities of small pipes effectively. Pipes are placed in a drum or chamber where media movement removes burrs.
Plasma Cutting
Plasma cutting is sometimes used to precisely cut and remove burrs simultaneously, especially useful for pipes requiring accurate and clean edges.
Laser Deburring
Laser technology is used for precise deburring, particularly for complex shapes and small parts. It is a non-contact method that can be automated for efficiency.
When selecting a deburring method, it is essential to consider the specific application requirements, material types, and surface treatment needs. Safety precautions should be taken, and the chosen method should adhere to industry standards and regulations. Post-deburring inspections are crucial to ensure the quality and safety of ERW welded pipes.
