Series 1500 Hyflex Expansion Joint family incorporates advanced bellows designs in various configurations for axial, lateral, angular, and multi axis motions. Catalog designs are available from as small as 1” NPS (25mm) through 144” (3600mm). Single ply, multi ply, and redundant ply technologies are available. Pressure ratings range from 25 PSIG through 300 PSIG. Larger sizes and higher pressures are available. Engineered 1500 Hyflex solutions are common for specific applications.
Internal flow liners, external shroud covers, rods, hinges, gimbals, purge ports, oversized bellows, travel limits, and other options are available. Cryogenic to extreme temperatures are supported via various material options and the inclusion of insulation or refractory lining.
The Series 1500 Hyflex family is comprised of three groups of products: single expansion joints, universal expansion joints and Fluid Catalyst Cracking (FCC) joints for refineries. Single joints are predominantly for axial motions, angular motion, and pressure balanced axial motions. Universal joints allow lateral motion, multi axis motions, and pressure balanced multi axis motions. FCC joints are provided in engineered configurations to support various motions. They include 2-ply redundant testable bellows, refractory lining, and specific support structures.
Universal, hinge, and gimbal configurations allow maximum motions while inducing the lowest forces to pipe systems and structures. Pressure balanced joints eliminate pressure thrust and offer lower forces than axial motion designs. Inline pressure balanced joints are compact non-thrust axial motion designs. Inline seismic universal expansion joints provide for minimum space multi axis motions. Inline pressure balanced universal hinge or gimbal joints support low force multi axis applications.
