S355JR Conveyor Pipe
Conveying seamless pipes are steel pipes formed by punching through round steel, with no welds on the surface. According to the production method, seamless pipes are divided into hot-rolled seamless pipes, cold-rolled seamless pipes, cold-drawn seamless pipes, and hot-expanded seamless pipes. Seamless pipes are classified into two types based on their cross-sectional shape: circular and special-shaped.

S355JR Conveyor pipe is a high-strength carbon steel pipe widely used in material handling, mechanical structures, and industrial conveying systems. It belongs to the EN 10025-2 standard, which specifies non-alloy structural steels with excellent weldability, formability, and impact resistance. With its balanced mechanical properties and reliable performance, S355JR pipe is a preferred choice in industries such as mining, cement, power generation, and bulk material transportation.

Parameters:

Chemical Composition:

• Carbon (C): ≤ 0.24%
• Manganese (Mn): ≤ 1.60%
• Silicon (Si): ≤ 0.55%
• Phosphorus (P): ≤ 0.035%
• Sulfur (S): ≤ 0.035%

These controlled alloying elements ensure good mechanical strength and excellent impact resistance at low temperatures.

Mechanical properties:

• Yield strength: ≥ 355 MPa
• Tensile strength: 470–630 MPa
• Elongation: ≥ 22%
• Impact energy (Charpy V-notch, 20°C): ≥ 27 J

These characteristics make S355JR Conveyor Pipe suitable for medium to heavy-duty conveying systems that demand both rigidity and resilience.

Advantages :

• High Load Capacity: The high yield strength allows it to support heavy conveyor loads and long spans without deformation.
• Excellent Weldability: The low carbon content enables easy welding using standard methods such as MIG, TIG, and arc welding.
• Superior Durability: Its strong resistance to wear, impact, and vibration ensures long service life in demanding environments.
• Versatility: Can be used in straight, bent, or spiral conveyor systems for transporting bulk materials like ores, coal, cement, or grains.

Cost-Effective: Provides an optimal balance between performance and price compared to alloyed steel pipes.​
