sn4 sn6 sn8 sn10 krah polyethylene pressure pipes
SN4, SN6, SN8, and SN10 Krah polyethylene pressure pipes represent advanced solutions in modern pipeline infrastructure. These pipes are manufactured using cutting-edge spiral wound technology, offering various ring stiffness classes to meet different installation requirements. The numerical designations (4, 6, 8, 10) indicate the pipes' ring stiffness in kN/m2, providing options for different soil and loading conditions. These pipes feature a unique profile structure that combines lightweight design with exceptional strength, making them ideal for both pressure and non-pressure applications. The manufacturing process involves high-quality polyethylene materials, ensuring excellent chemical resistance, long service life, and superior hydraulic performance. These pipes are commonly used in water supply systems, sewerage networks, industrial applications, and marine outfalls. Their structured wall design optimizes material usage while maintaining structural integrity, making them both economical and highly efficient. The pipes' smooth internal surface minimizes friction losses and prevents sediment accumulation, while their robust external surface provides excellent resistance to external loads and environmental factors.
