METAL EXPANSION JOINTS
Metal expansion joints are primarily used to absorb movements in piping caused by thermal changes. The Matchless design incorporates the latest technology to produce a premium product.
- The Matchless expansion joint bellows are produced from fully annealed stainless steel sheet rolled into a tube and seam welded.
- Standard Bellows: 321 stainless steel. Various alloys are available to withstand your toughest applications.
- Standard Fittings: welding nipples, fixed and floating flanges
- Standard Sizes: 2" through 144".
