Edge Welded Bellows – DN40

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:

Temperature range:
      – 316L : operating at Ambient, baking up to 80˚C.
      – Higher temperature versions are available, please call us to discuss.

Materials:
      – Flanges : 304(L) stainless steel as standard.
      – Bellows : 316L stainless steel as standard.
