This is a significant length change compared to other piping materials and should be taken into account during piping system design. Flexpert Bellows believe that our strong faith in client feedback coupled with our relentless commitment towards the highest possible product quality standards makes our piping expansion joints such a success. Will the lack of an expansion joint hamper or destroy the function of the facility, or cause damage to the structural or architectural compo-nents? C. Longitudinal joint spacing on two-lane and multilane concrete pavements typically is about 10 to 13 ft (3. 19. EJMA carries out extensive technical research and testing on many important aspects of expansion joint design stxndard ejma standard. 179” / 100 feet for steel – 1. The following guidelines are recommended as bases for expansion joint design and location: Expansion joints should extend over the entire height of the building from the top of the foundation footing (or perimeter basewall) through the roof. Preparing FEA Models for 4 different conditions of expansion joint i. Based on customer requirement, Design calculation can be made as per EJMA standard and ASME. This coefficient results in an approximate expansion for pipe of 1/10/100, that is, 1 inch for each 10°F change for each 100 feet of pipe. These effects result from the way the joint is loaded, as well as how the joint responds to the load. Values of 135 psi and 95 psi are recommended for this calculation.

These are the loads to which the expansion joint can be subjected. expansion joints are necessary it is important that they be sealed and drained in order to protect both superstructure and substructure components from deterioration caused by runoff and deicers. First, joint depth should be between 1/4 and 1/3 of the total slab depth to ensure crack formation at the joint. When an unrestrained expansion joint is introduced in the network, the force tends to pull the ends away from the expansion joint causing damage to itself and the pipe. If left unrestrained, a bellows under pressure will extend past its rated movement.

Pressure thrust (effective area x design pressure). 5 Fig. The design and operation of gathering, transmission, and distribution pipeline systems are usually governed by codes, standards, and regulations. Relaxation of the elastomer and debris accumulation atop the seal contribute to seal slippage. Since 1962, SFZ has been active in the design and the manufacturing of metal expansion joints all over the world, tailored to internal regulations, calculation  displacement exceeding the design value to the expansion joint. This tool provides an estimate of the maximum allowable joint spacing based on the slab thickness and the subgrade/subbase used, two of the variables with the most prominent effect on joint spacing requirements. These are some of the basic design of the thick joint. 04) As with all types of expansion joints, the designer should guard against damaging conditions for which these devices cannot EBAA Iron, Inc. Joints should be spaced about 10 feet and a maximum of 15 feet.
