In the realm of industrial applications, SSAW (Spiral Submerged Arc Welded) steel pipes are pivotal in various sectors, particularly in transporting gas and fluids. In this article, we will delve into the four primary corrosion protection systems utilized for SSAW steel pipes: the three-layer PE anti-corrosion system, fused epoxy powder (FBE), coal tar enamel, and polypropylene reinforced fiber tape. 1. Three-Layer PE Anti-Corrosion System The three-layer PE anti-corrosion system comprises an epoxy primer (≥80μm), an adhesive layer (170-250μm), and a polyethylene topcoat (2.5-3mm). This robust system offers exceptional impact resistance, achieving a strength of 10J/mm, making it suitable for various soil conditions. 2. Fused Epoxy Powder (FBE) Fused epoxy powder has a single-layer structure ranging between 300-500μm. Renowned for its superior compatibility with cathodic protection systems, FBE is applied through electrostatic spray at a pre-heated temperature of 230±5°C. Once cured, ...

In the world of manufacturing, hot-dip galvanized steel pipes have emerged as a critical component across various industries including construction, machinery, coal mining, chemical production, power generation, railway vehicles, automotive, road infrastructure, bridges, containers, sports facilities, agricultural machinery, oil machinery, exploration equipment, and greenhouse construction. This extensive range of applications underscores the importance and versatility of hot-dip galvanized steel pipes. What are Hot-Dip Galvanized Steel Pipes? Hot-dip galvanized steel pipes are welded steel pipes that are coated with a layer of zinc through a hot-dip galvanization process. This coating significantly enhances the steel pipe's resistance to corrosion, thereby extending its lifespan. The galvanization process involves immersing the steel pipes in molten zinc, ensuring a thick and durable protective layer that can withstand harsh environmental conditions. Advantages of Hot-Dip Galvan...
