Welcome to the DME Tour

Sheet metal fabrication equipment

The precision shearing operation is a critical first step to forming a bellows

More sheet metal fabrication equipment

Longitudinal seam welding is another crucial step in the bellows manufacturing process

Making X-ray quality seam welds is standard practice

Vanstone stub ends made from Inconel, Monel and Hastelloy start with the seam welding process

The bellows convolutions are carefully formed to minimize material thinning

Forming large diameter bellows requires teamwork

Bellows ready for the finishing stages in the manufacturing sequence

Precision bellows re-rolling process prevents sidewall scratching during this critical step

Making a bellows to its engineered specifications is an art

The bellows necks are carefully trimmed to the finished length

Flow liner being expanded to fit the expansion joint

Roll seam welder used to seal plies on multi-ply bellows

18 gauge stainless steel sheet metal flanges are attached to this bellows using roll seam method

We have an extensive inventory of stainless steel and exotic alloy coil for bellows manufacturing
