Abstract: A pipe joint includes at least a first and a second pipe. A section of the first pipe is opened out and a further section of the second pipe is inserted into the section, so that both pipes overlap in an overlap region. A gap is formed between the section and the further section, into which gap a free-flowing sealing medium can be introduced via an input passage. In the method, a first and a second pipe are fitted together, a sealing medium is introduced into the gap between the pipes via an input passage, air located in the gap escaping via at least one output passage, and the input passage and the output passage are closed. The sealing medium, preferably an epoxy-resin/glass-fiber mixture, ensures especially effective sealing of the pipe joint and also an especially stable frictional connection between the pipes.

Abstract: The object is, by simple measures, to ensure a particularly smooth inner surface and maintain particularly high dimensional accuracy of a pump housing of a cooling-water pump for a power plant. For this purpose, the cast-concrete pump housing of the cooling-water pump has, according to the invention, a number of formwork elements made of glass-fiber reinforced plastic.
