The Metal Bellows Expansion Joint (Welding Neck, Without Liner, PN16) is built for heavy-duty applications requiring maximum flexibility and durability. Its stainless steel bellows structure compensates for expansion, contraction, vibration, bending and misalignment in industrial pipelines.
Thanks to its welding-neck connection, this model provides excellent sealing integrity and is ideal for systems exposed to high pressure and temperature fluctuations. The absence of an internal liner offers a compact design and allows efficient movement absorption while maintaining high resistance to corrosion.
This compensator is widely used in steam systems, superheated water lines, hot oil networks, compressed air installations, and all environments where long-term reliability and mechanical protection are required.
