MAGNAPLAST Kolano 30° KGB external sewer elbow 200 mm (23110)

MAGNAPLAST Kolano 30° KGB external sewer elbow 200 mm is a rigid 30-degree pipe fitting intended for use in underground gravity sewer systems. Designed for external sewage and stormwater drainage, this elbow enables a smooth directional change in 200 mm pipeline runs while maintaining hydraulic capacity and alignment. The component is manufactured to suit buried KGB-type installations where a low-angle deviation is required to negotiate obstacles or to align sections of sewer and drainage networks.

Advantages

The 30° elbow provides a controlled directional change with minimal flow disturbance and reduced risk of clogging compared with abrupt bends. Its dimensional compatibility with 200 mm sewer pipes ensures secure connections and consistent sealing performance in buried conditions. The product is made to withstand typical external loadings and soil conditions encountered in underground drainage installations, offering long-term dimensional stability and reliable hydraulic performance.

Suitable for

• External gravity sewer pipelines with 200 mm diameter
• Stormwater drainage systems in residential and commercial sites
• Underground pipeline assemblies requiring a gradual 30° change of direction
• Repair and extension works on buried sewer networks

Key specifications

• Angle: 30° bend for directional change
• Nominal diameter: 200 mm suitable for standard KGB external sewer lines
• Application: buried gravity sewer and stormwater drainage
• Connection type: socket/joint compatible with 200 mm KGB pipes
• Design purpose: maintain hydraulic flow and alignment in underground installations

How to use

Install the elbow as part of the 200 mm sewer run where a 30° deviation is required. Prepare pipe ends by cleaning and checking for damage, then assemble according to standard KGB socket/joint procedures, ensuring proper insertion depth and alignment. Use appropriate sealing materials or gaskets if specified for the pipe system to achieve a watertight joint. After assembly, backfill and compact surrounding soil in layers to provide uniform support and to avoid point loads on the fitting.

Usage recommendations

Prior to installation verify compatibility with the existing pipe system and follow local regulations and installation standards for buried sewer components. Avoid applying excessive bending or point loads during handling and ensure connections are clean and correctly seated to maintain long-term hydraulic performance.
