Welding neck with loose flange

Experience has shown that the welding neck with loose flange from Reinert-Ritz is partic­u­larly suitable for unpres­surized systems and appli­ca­tions with low pressure. In addition to the usual standard sizes, we also offer customized solutions up to a diameter of 2000 mm that take your special require­ments into account.

Welding neck collars with loose flanges were in fact the first flange connec­tions that could be used to produce transi­tions on fittings and flanges made of other pipe materials.

A flange connection is a system consisting of a collar, flange screw connection and the appro­priate gasket. When selecting the flange connec­tions, the corre­sponding pressure and force ratios must always be taken into account. You can find an overview of all Reinert Ritz flange connec­tions here.

The Reinert Ritz welding neckband is made of robust material that guarantees a long service life. The backing flanges are made of corrosion-free, fiber-reinforced plastic or steel with a plastic coating in accor­dance with DIN EN 10310. The weld-on collar, on the other hand, is made of PE100 plastic.

The loose flange solution is always a system consisting of a welding neck (flare, welding neck ring) and a matching loose flange. This flange rotates freely on the welding neck and can therefore be aligned with the mating flange.

In summary, a welding neck collar with loose flange offers a reliable, flexible and cost-effective connection solution for pressureless systems.
