Product catalog summary
Installation Instructions for BIOFLEX Pipe System BGT

Specifications and Components
The BIOFLEX pipe system is designed for use in fermenters and includes components such as corrugated pipes, end connectors with graphite sealing rings, pressure rings, supporting rings, and stirrup clamps. Dimensions are specified in millimeters.

Preparatory Work
Before installation, ensure the corrugated pipe is not attached to the bending support and two additional supports over a length of 3.0 to 3.6 meters. The pipe end should extend about 1.5 meters beyond the fixed point of the bending support.

Bending and Securing the Pipe
A minimum of 4.5 meters of loose pipe end is required to insert the pipe into the core hole without kinking. The pipe is pushed through the core hole and secured with a lashing strap.

Fixing and Aligning the Pipe
Stirrup clamps are used to secure the pipe to supports, ensuring it is centrally aligned in the core hole. Mark the pipe position before drawing it into the tank.

Fitting the Connector
The wall duct, 250 mm long, should be shortened if the tank wall is thinner. Fit the connector with external thread, ensuring the guide pin aligns with the groove. Align the pressure ring, supporting ring, and sealing ring precisely.

Final Installation Steps
Secure the connector by hammering groove pins into place, ensuring the pressure ring remains level. Fit the lashing strap and stirrup clamps as shown, and tighten washers with a torque wrench to a maximum of M8 = 10 Nm.

Application Example
The BRUGG Fermenter heating system is used in the world's largest biogas park in Könnern, demonstrating the scale and complexity of the installation.

CALPEX® heat-insulated pipe CALPEX® can be laid direct into the trench with a minimum of work. Connections in the ground can largely be dispensed with. Due to its pre-insulation, the pipe has a high insulation coefficient. The advantage: energy loss is kept to a minimum. The desired length is delivered on site in one piece in a coil. Grouted or screwed connectors. Dimensions: DN 20 - DN 150 Extensive district heating networks PREMANT® plastic-sheathed piping is specially designed as a mains pipe for large-scale district heating networks. The properties: high insulation coefficient and leak detection...

BIOFLEX corrugated piping BIOFLEX is a single-walled corrugated piping system made of stainless steel. The key constructional element of these pipes manufactured at our works in long lengths is the helically corrugated pipe. Connector technology Optimized connections and fittings enable the pipes to be coupled to all standard connections. A flameless graphite packing technology (GRAPA) is used here. This easy-to-fit connector system enables time-savings on installation work without welding. System advantages - surface up to 50 % higher maximum heat transfer through optimized wall thickness -...
