Marzouk Steel, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium steel products, serving industries that demand strength, durability, and precision. Among its specialized offerings are Alloy Steel WP5 Pipe Fittings, designed for high-pressure, high-temperature, and critical piping applications. Manufactured using advanced forging and forming technologies with stringent quality control, WP5 fittings provide exceptional tensile strength, toughness, and corrosion resistance. Marzouk Steel ensures that every WP5 pipe fitting meets international standards, providing engineers and fabricators reliable solutions for power generation, petrochemical plants, oil and gas pipelines, and heavy industrial piping systems.
Alloy Steel WP5 Pipe Fittings are made from high-grade chromium-molybdenum (Cr-Mo) alloy steel, engineered for superior tensile strength, hardness, and thermal stability. The chemical composition, including carbon, chromium, and molybdenum, enhances toughness, impact resistance, and fatigue strength. WP5 fittings respond well to heat treatment, optimizing mechanical properties such as yield strength, tensile strength, and toughness. Designed to maintain structural integrity under high-pressure and high-temperature conditions, these fittings are ideal for demanding industrial, petrochemical, and power generation applications requiring reliability and long-term performance.
