Compensadores y Dilatadores del Norte, S.L. (CODINOR), founded in 1992 and based in Zamudio (Bizkaia), specializes in the engineering and production of metallic expansion joints, bellows, and flexible piping systems.

Codinor uses hydroforming to manufacture multi-convolution metallic bellows, applying internal hydraulic fluid pressure inside specialized tooling to simultaneously shape all convolutions of the cylinder. This process yields uniform wall thickness, high flexural capability, and complete hermetic sealing for vacuum and high-pressure duties.

Codinor operates according to EJMA, EN 14917, and EN 13445 manufacturing standards and holds UNE-EN ISO 9001:2015 certification, supplying industrial processing plants worldwide.

Codinor delivers custom-engineered metallic flexible components and expansion devices:

Hydroformed Metallic Bellows: Simultaneous hydraulic convolution forming creating single- or multi-ply bellows with high elasticity, cycle endurance, and vacuum-to-high-pressure tightness.
Circular Metallic Expansion Joints: Nominal diameters ranging from DN 8 mm up to DN 7,000 mm, configured for axial, lateral, angular, or combined thermal movement absorption.
Alternative Forming Processes: Mechanical roll forming and elastomeric expanding-mandrel convolution shaping for thick-walled or oversized profiles.
Materials: Austenitic stainless steels (AISI 304, 316, 321), high-nickel alloys (Inconel, Incoloy, Hastelloy), Monel, titanium, and PTFE-lined composite bellows.
Ancillary Equipment: Dismantling joints (Dresser type), rectangular expansion joints, and metallic flexible hoses.
