The invention relates to a flexible lance for machining or inspecting a tubesheet of a boiler, having a first strip made of a flexible, metallic material and a second strip made of a flexible, metallic material, wherein the second strip is arranged on the first strip in the longitudinal direction, and wherein at least the second strip has a shaped portion extending in the longitudinal direction for receiving a supply line for a machining or inspection head arranged at the free end of the flexible lance, and wherein the first strip is connected to the second strip such that an open side of the shaped portion is covered by the first strip so as to form a guide channel, and wherein at least one edge region of the flexible lance, extending in the longitudinal direction, is formed only by the first strip or the second strip.
A flexible lance for machining or inspecting a tubesheet of a boiler, having a first strip from a flexible, metallic material, and a second strip from a flexible, metallic material, wherein the second strip in the longitudinal direction is disposed on the first strip, and wherein at least the second strip has a shaped feature, extending in the longitudinal direction, for receiving a supply line for a machining or inspecting head that is disposed on the free end of the flexible lance, and wherein the first strip is connected to the second strip in such a manner that an open side of the shaped feature is covered by the first strip so as to form a guide duct, and wherein at least a peripheral region, extending in the longitudinal direction, of the flexible lance is formed only by the first strip or the second strip.
