hdpe krah pipe specifications
HDPE Krah pipes represent a cutting-edge solution in modern pipeline systems, characterized by their distinctive spiral wound profile structure and high-density polyethylene composition. These pipes are manufactured using advanced technology that creates a double-wall structure, combining superior strength with lightweight properties. The specifications of HDPE Krah pipes include diameters ranging from 300mm to 4000mm, with customizable wall thicknesses to meet specific project requirements. The pipes feature a smooth inner surface that ensures optimal flow characteristics and minimizes friction losses, while their corrugated exterior provides exceptional structural stability. The standardized specifications include resistance to chemical corrosion, UV radiation protection, and temperature variations from -40°C to +60°C. These pipes are engineered to maintain their structural integrity under various load conditions, with a minimum service life of 100 years under normal operating conditions. The manufacturing process adheres to international standards such as DIN 16961 and ISO 21138, ensuring consistent quality and performance. The pipes' design incorporates specialized joining systems, including electrofusion welding and extrusion welding methods, guaranteeing watertight connections and system reliability.
