Stainless steel butt welding ring loose sleeve flange

Product Introduction Loose-set flange, also known as loose-set flange or semi-fixed flange, is a common pipe connection. Its main feature is that the inner and outer rings of the flange are welded structures, and the middle part of the loose sleeve can be freely expanded to adapt to the displacement of the pipeline due to temperature changes or thermal expansion and contraction.   The working principle of the butt welded ring loose sleeve flange is: when the pipeline is heated and expanded, the inner ring and outer ring of the flange will not produce relative displacement, but the middle loose sleeve part absorbs the expansion amount to maintain the tightness and integrity of the pipeline system. This not only avoids the damage caused by expansion of the pipeline, but also reduces the wear of the flange and prolongs the service life.  …
