DME custom designs metal bellows capsules in accordance with the Expansion Joint Manufacturer's Association (EJMA) guidelines. We supply qualified fabricators, pre-engineered metal bellows, flow liners and vanstone stub ends to meet the customer's individual requirements. Single ply and multiply metal bellows capsules are available in sizes 1-1/2? through 104? diameter. Metal bellows can be made in most alloys. DME uses T-321 stainless steel as a standard due to its excellent forming and high temperature properties. Other common alloys stocked at DME include T-316 and T-304 stainless steel, Inconel 625, Monel 400 and Hastelloy C276.
