Free flange Ø100

The professional steel loose flange with a nominal diameter of DN 100 and a working pressure class of PN10 is a heavy industrial fastener, specially designed for the construction of combined pipeline networks. The main engineering function of this item is to provide a reliable mechanical connection between polyethylene (PE) pipes and metal flanged fittings - stopcocks, check valves, filters or measuring devices (water meters). The flange is mounted loosely on the pipe behind a specialized polyethylene flange tip (collar). When tightened with bolts, it presses the PE collar to the opposite flange of the fitting, creating an extremely strong, detachable and monolithic assembly, capable of withstanding high hydraulic loads and vibrations.

Made from selected, thick-walled, high-density steel, this loose flange features superior resistance to mechanical deformation, torsion and sudden temperature amplitudes. Its flexible rotational nature facilitates the work process, as it allows easy rotation around the pipe axis for perfect matching of bolt holes during installation. The product meets strict industry standards for geometric accuracy and hole spacing, which guarantees full compatibility with mass flange elements on the market. It is an indispensable component for the safe and long-lasting construction of external and internal water supply lines, automated irrigation systems in agriculture and fire safety installations of facilities.

Purpose:

• For connecting polyethylene pipelines with a diameter of DN 100 to industrial flange fittings
• For installation in internal and external water supply networks for drinking and process water
• For the construction of main supply lines in fire and security sprinkler systems
• For implementation in large-scale agricultural and rural irrigation and hydromelioration systems

Main advantages:

• Extremely easy leveling during installation thanks to the free rotation of the body around the pipe
• Impeccable structural strength and safety under pressure of 10 bar (PN10) due to the solid steel alloy
• Full universal compatibility with standard flange fittings according to European plumbing standards
• Quick and clean bolt-on installation with M16 fasteners, allowing easy subsequent disassembly for inspection or repair
