Edge Welded Bellows – DN200

LewVac edge welded bellows are more suited to applications that require greater flexibility, particularly axial compression and extension. Edge welded bellows are manufactured from a series of formed metal diaphragms welded together. Each diaphragm contributes to the overall extension / compression. More discs means greater extension attainable and also the greater the lateral offset achievable.

Features:

• 316L stainless steel as standard for lower cycle requirement applications (typically 10,000 cycles).
• AM350 stainless steel also available for long lifetime (typically 500,000 cycles).
• Titanium, Inconel^® or Hastelloy^® available on request.
• 304 stainless steel end plates, tubes and flanges as standard.
• Custom sizes and designs available on request.
• One fixed, one rotatable flange on CF assemblies.

Specifications:
