  How to protect boiler tube from corrosion?

  Boiler tubes are a specialized category of steel tubes and are predominantly manufactured as seamless steel pipes. Consequently, corrosion protection for boiler tubes must be implemented as a full-life-cycle strategy, covering design and material selection, surface protection, chemical water treatment, operational control, and shutdown maintenance.

  Differences between spiral steel pipes and straight seam welded steel pipe

  Spiral steel pipes and straight seam welded steel pipes are two of the most commonly used welded pipe products in large-scale pipeline and structural applications. While both rely on advanced welding technologies to achieve reliable mechanical performance, their manufacturing processes, welding methods, and application characteristics differ significantly. Understanding these differences is essential when selecting the most appropriate pipe type for a specific project.

  Connection methods of the industrial spiral steel pipes

  In most applications, spiral steel pipes are connected by welding, as welded joints are cost-effective and suitable for the majority of project requirements. However, in certain projects, factors such as tight construction schedules, site constraints, operating conditions, or complex geographical environments may limit the use of welding. In such cases, alternative connection methods—such as threaded, flanged, socket, and grooved connections—are adopted. Below is an overview of the main non-welded connection methods used for spiral steel pipes and their characteristics.
