Steel Expansion Joint
Steel expansion joints, designed for piping systems to connect pipes and flanges, adjustable telescoping restraint with tie-rods. Ideal for systems that require periodic maintenance, the steel expansion joints can be adjusted to length to allow access for installation or removal of valves and other equipment.
Features and Benefit:
·For steel and ductile iron pipes, other materials on request
·Flange connection, flange drilling can base on DIN PN6/16/25, ANSI CLASS150/300, JIS, EN, etc
·For use in pipelines where larger than usual longitudinal movements are concentrated
·Reduce assembling time
·Epoxy powder coating and bolting made of steel
·Drinking water approved
