As detailed by Pumps & Systems in the article, “Where to Find Technical Information About Rubber Expansion Joints,” the newly released Technical Handbook for Expansion Joints Piping 8.1 by the Fluid Sealing Association offers in-depth answers to fundamental questions regarding rubber expansion joints. Covering topics from types and functions to installation, this handbook is a comprehensive resource aimed at engineers who design and install piping systems. 

The handbook, developed by the Fluid Sealing Association’s expansion joints piping division, consolidates standards and guidelines to aid engineers in selecting, designing, and maintaining rubber expansion joints in diverse applications. It includes details on elastomers, design configurations, accessories, and technical specifications. For example, rubber expansion joints are defined as flexible pipe connectors made from various materials like natural elastomers, fabrics, and sometimes metallic reinforcements, all intended to provide stress relief in piping systems. They play a vital role in mitigating the impacts of vibration, noise, and pressure surges.

The guide also delves into two common types of rubber expansion joints: the spool type and the molded sphere type. The spool type, often featuring a full-face rubber flange, is known for its versatility in accommodating different configurations, including open or filled arch designs for abrasive applications. The molded sphere type is another design commonly used for its reliability in vibration dampening and flexibility. The handbook addresses these and other design variations, providing engineers with essential insights to match expansion joints to specific system requirements.
