The 11th Edition of the EJMA Standards

The EJMA Standards are recognized throughout the world as the authority on the proper selection and application of metallic bellows type expansion joints for safe and reliable piping and vessel installation. The Eleventh Edition standards combine the knowledge and experience of the leading manufacturers of expansion joints into an invaluable reference document.

EJMA’s Practical Guide to Expansion Joints, a pocket size primer based on the EJMA’s Standards, is intended to provide users with a basic understanding of expansion joints. It will also assist the user in communicating design requirements to the manufacturers and to properly install and maintain the expansion joint in service. (NOTE: This guide is not intended as a source for expansion joint design or application details.) The guide is sold separately.
