Steel elbow
Steel Elbow Manufacturer & Supplier Tunisia, Algeria
Steel elbows are essential pipe fittings used to change the direction of flow in piping systems, typically at angles of 45°, 90°, and 180°. At Emirerri Steel , we manufacture and supply high-quality steel elbows that comply with French AFNOR standards (NF EN / XC series) , guaranteeing durability, corrosion resistance, and engineering precision.
Our steel elbows are widely exported to Tunisia, Algeria, Morocco and Libya , serving sectors such as oil and gas, petrochemical, construction and water treatment.
Types of Steel Elbows
According to the radius
- Long radius (LR) elbow – smoother flow, less pressure loss
- Short radius (SR) elbow – compact design for tight spaces
According to the manufacturer
- Seamless elbows
- Welded elbows
According to the function
- Reducing elbow (different diameters)
- Equal elbow
