projects
Clamshell expansion joints FCC
Express delivery with clamshell expansion joints. Clamshell bellows are components designed and fabricated as two 180° segments. They are intended to be installed over the existing FCC Catalyst Regenerator Standpipe Expansion Joint on-site.
Pressure balanced / corner relief expansion joints
Four multi-ply pressure balanced / corner relief expansion joints for a European provider of nitrogen-based products in the fertilizer and industrial chemical market.
Bellows / Expansion joints for the ITER fusion project
Delivery of over 90 expansion joints / bellows DN 96 for the ITER fusion project. 2-ply bellows with inter-ply connections for permanent leakage control.
Crackling bellows Hastelloy C22 / Alloy C22
Client: Technology and system provider for the chemical industry. The shaft bellows are installed in stirring / mixing units for chemical processes
Axial expansion joint DN 600 Hastelloy C22 / Alloy C22
Multi-ply axial expansion joint DN 600 for a manufacturer of pharmaceuticals based in Northern Europe.
Expansion joint DN 1458 / 2.4602 Hastelloy C22 / Alloy C22
Multi-ply universal expansion joint DN 1458 for a customer in Southeastern Europe, focused on the extraction and processing of mineral raw materials to end metal products.
8 FCC Expansion Joints
Replacement of eight FCC Expansion Joints for a refinery in Europe. Five expansion joints are refractory lined. The expansion joints were extensively tested and inspected.
Lateral expansion joints
Lateral expansion joints specifically designed and manufactured for use in a clean energy complex producing blue hydrogen and blue ammonia in USA. The complex will produce blue hydrogen as well as blue ammonia for global hydrogen markets such as the transportation and mobility sectors.
Expansion joints for Energy from Waste
Two gimbal multi-ply expansion joints DN 3200 and two lateral expansion joints DN 2235. One corner relief multi-ply expansion joint DN 3200, segmented version without T-piece. We provided the pipework constructor with the design drawings of the T-piece and the assembly plans to ensure that the end customer receives a tailored and complete module on site.
Multi-ply reinforced rectangular bellows
First of a kind prototype for a multi-ply reinforced rectangular bellows for cryogenic application. Our engineering team have designed this tailored reinforced bellows for a fusion reactor in USA. The unique construction of this multi-ply rectangular reinforced bellows is that there are no welding seams in the corner areas. The initial design was validated with in-depth finite element analysis, followed by a 1:1 scale prototype. The prototype was successfully tested at 32 bar g
