Very useful for minimizing vibration and sound transmission from pumps into piping and building structure. These need to be engineered and selected properly to assure the best isolation and system integrity.
Rubber expansion joints are capable of axial compression, axial expansion, transverse and angular movements. In many cases, three movements are all taking place at one time. Standard expansion joints have movement limits, but they can be increased by changing to multiple arches or single piece construction with an arch at each end and a long intermediate hose body. Control rods are used when the piping is not adequately restrained
METALLIC EXPANSION JOINTS (BELLOWS)
Metallic Expansion Joints are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces.
There is a wide range of metallic bellows designs in a variety of materials. Options range from the simplest convoluted bellows used in petroleum refineries.Materials include all types of stainless steels and high grade nickel alloy steels.Any pipe connecting two points is subjected to numerous types of action which result in stresses on the pipe. Some of the causes of these stresses are :internal or external pressure at working temperature weight of the pipe it self and the parts supported on it movement imposed on pipe sections by external restraints thermal expansion
RUBBER EXPANSION JOINTS
Rubber Expansion Joints are a flexible connector fabricated from natural or synthetic elastomers, and fabrics with metallic reinforcements designed to provide stress relief in piping systems due to thermal changes.
When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is the ideal solution. Rubber expansion joints compensate for lateral, torsion and angular movements preventing damage and undue downtime of plant operations.The special construction of the rubber joints can solve problems like: Vibration, Noise, Shock, Corrosion, Abrasion Stresses, Load Stress, Equipment Movement,Vibration, Pressure Pulsation and Movement in a Piping System
TEFLON EXPANSION JOINTS
Teflon Expansion Joints corrosion proof, non-aging with extraordinary flex life and unmatched reliability.
The Teflon® expansion joint has a widespread acceptance in the chemical processing industry, piping applications where acids and highly corrosive chemicals are being handled and commercial heating and air conditioning systems as pump connectors and a strategic point throughout a system.
They can be used to compensate for :
• Movement, Misalignment, Axial Travel
• Angular Deflection, and or Vibration in Piping Systems
EXPANSION JOINTS screwed ends
An expansion joint suitable for small diameter pipes where a screwed connection rather than a flange is required. Twin sphere design for high movements.
