The FL machine range for processing complex membrane walls

We offer a specialised technology to bend full membrane tube walls for use in modern boiler and power plant construction. FL machines process full membrane tube walls up to a maximum width of 3,600 mm in a single operation. They are also capable of oblique bending which facilitates the production of a “gradient” in the boiler wall, eliminating the substantial costs of adjustment and fitting when assembling the boiler. All machines are equipped with a state-of-the-art CNC system which also takes account of springback, for example, when bending membrane tube walls. If required, the membrane wall bending machine can be equipped additionally with a machine pivoting device, a membrane wall transport roll and a hydraulic membrane wall stop.

Boost in productivity in boiler and power plant construction

Membrane tube walls are indispensable in modern boiler and power plant construction. The production of very large bent membrane walls enables users to benefit from significant cost savings, shorter production times and reduced assembly effort. Even a minimal deviation in a bend can mean that a membrane wall no longer fits the next segment. That is why FL membrane wall bending machines are especially precise and outperform the tolerance specifications for wall thinning and ovality prescribed by all international standards including EN 12952 and ASME B31.1.
