The Externally Pressurized Metal Bellows Expansion Joint (Weld Neck, PN16) is engineered for extreme operating conditions where high axial movement, thermal expansion and system vibration must be safely compensated. Thanks to its external pressure technology, the bellows are protected from buckling and mechanical stress, ensuring maximum operational safety and long service life.
The weld-neck design provides a rigid, leak-free and durable connection suitable for pipelines exposed to continuous pressure cycles, thermal variations and dynamic loads.
Made of high-grade stainless steel, this expansion joint delivers outstanding resistance to corrosion, high temperatures and demanding industrial environments. It is widely used in steam, superheated water, compressed air and hot oil systems.
