Kaikki mitä sinun tarvitsee tietää: Lämmön aiheuttama vyöhyke putkilinjan hitsauksessa

Introduction In pipeline welding, the integrity of welded joints is crucial to ensuring the long-term safety, durability, and efficiency of the pipeline infrastructure. One critical aspect of this process that is often overlooked is the Heat-Affected Zone (HAZ)—the area of the base metal that is altered due to the heat applied during welding. While the […]

Kuinka valita oikea projektiisi: Hitsauselektrodit

Introduction Welding is a critical process in many industries, especially in the fabrication and joining of metal materials like steel pipes, plates, fittings, flanges, and valves. The success of any welding operation depends heavily on choosing the right welding electrodes. Selecting the appropriate electrode ensures strong, durable welds and reduces the risk of defects, which […]

Oikeiden pinnoitteiden valinta: 3LPE-pinnoite vs. FBE-pinnoite

Introduction In the oil, gas, and water transmission industries, pipeline coatings play a crucial role in ensuring the long-term performance and protection of buried or submerged pipelines. Among the most widely used protective coatings are 3LPE (Three-Layer Polyethylene Coating) and FBE (Fusion Bonded Epoxy Coating). Both provide corrosion resistance and mechanical protection, but they offer […]
