  2. Ensuring Longevity in Pipe Coating through Surface Preparation

    Surface preparation for pipe coating in the oil and gas industry is a process that demands precision and attention to detail. Given the industry's stringent requirements, where pipes are often expected to have a lifespan exceeding 25 years, every aspect of the preparation process becomes critical. The dual goals of this process are to remove any scale or rust and to create the most suitable surface profile for coating adhesion.

    The Significance of Surface Preparation

    In pipe coating, the stakes are high. The presence of oxides, dust, roughness, and soluble salts on the pipe's surface can significantly impact the quality and longevity of the coating. Therefore, the blasting process, which is employed for surface preparation, must be meticulously monitored and controlled.

    1. Removing Scale and Rust

    The first step in surface preparation is the removal of scale or rust. This is crucial for ensuring that the coating adheres properly to the pipe. Any failure in this step can lead to coating failure, which in an industry like oil and gas, can have severe implications.

    2. Creating an Optimal Surface Profile

    Once the scale and rust are removed, the next goal is to create an ideal surface profile. This involves achieving a specific level of roughness that allows the coating to adhere securely to the pipe. This aspect of surface preparation is where products like GL40, GL25, and Surfium play a significant role.

    3. The Importance of Precise Monitoring

    Due to the stringent specifications in the pipe coating industry, the blasting operation must be carefully monitored. This ensures that the surface preparation meets the required standards, laying the foundation for a durable and long-lasting coating.

    Conclusion

    Surface preparation for pipe coating is a process that cannot be underestimated, especially in industries where reliability and longevity are non-negotiable. By focusing on detailed and precise surface preparation, using the right products and techniques, the industry can ensure the safety and durability of its pipelines.

  3. Shot Peening: Enhancing Durability in Steel Parts

    Shot peening is a critical process in the manufacturing and maintenance of steel parts, particularly those subjected to cyclic tension and compression. Steel, while highly resistant to compression, is vulnerable to cyclic tension, which can lead to surface cracks and eventual breakage. Shot peening addresses this challenge by creating an artificial compressive stress on the surface of steel parts, thereby extending their lifetime and allowing for lighter parts with equivalent performance.

    Understanding Shot Peening

    Shot peening involves bombarding the surface of steel parts with small spherical shots, typically ranging from S110 to

  4. Effective Descaling Techniques for Coils and Plates

    Descaling in the metalworking industry, especially for coils and plates, is a vital process post-lamination. After being subjected to high temperatures during lamination, coils and plates often develop a layer of scale on their surface. This scale, if not removed, can hamper further processing and affect the quality of the final product. While acid bath treatments are commonly used, blasting is essential to maximize scale removal and prolong the life of these acid baths.

    The Challenge of Scale on Coils and Plates

    Scale formed during lamination is not just a surface blemish; it represents a significant barrier to quality and efficiency. The acid bath, while effective, can become less efficient over time due to scale buildup. Therefore, additional mechanical descaling methods are crucial.

  9. TCO, Winoa's pillar of differentiation

    TCO, Winoa's pillar of differentiation  

     

    The TCO (Total Cost of Operation), or the "Total Cost of Operation" of sandblasting, is one of the pillars of Winoa's differentiation.

    Most companies think they can reduce the cost of blasting operations by buying cheaper abrasives. The problem is that, in reality, abrasives represent only 20% of the total cost of shot-blasting operations: therefore even a reduction in the purchase cost of the shot has little impact on the overall cost of the process.   Is there a more effective solution? Yes, considering all the elements involved: manpower, machines, maintenance, spare parts, wear, energy and waste, as well as the shot itself.
