If you are designing a piping system for a refinery, a power plant, an LNG facility, or an HVAC system, the EJMA Standard provides the mathematical formulas, safety factors, and design rules to ensure that your expansion joint will operate reliably for its intended life.

EJM is committed to maintaining high publication ethics and follows the standards outlined by the . Key policies include: Ejma Standard.pdf

The EJMA Standard.pdf is widely adopted in various industries that rely on metal bellows expansion joints, including: If you are designing a piping system for

: Covers circular and rectangular bellows under internal or external pressure. EJMA's influence extends worldwide, forming the basis for

EJMA's influence extends worldwide, forming the basis for many national and international codes, including sections of the like EN 14917 and EN 13445.

The standard provides methodologies for calculating the thermal expansion that a piping system will experience and how much movement an expansion joint must accommodate. It includes formulas for determining the stress and reaction forces on the expansion joint.
