Pipe lines with stainless steel expansion joints in the chemical industry

Pipe lines used for chemicals are designed in stainless steel. Depending on the corrosion load, simple or high-quality stainless steel, for example 1.4539, is chosen. Alternatively, additional interior coatings are an option, provided that the medium is not abrasive and the operating temperature is not too high. Expansion joints – shown in this project as stainless steel expansion joints – must be accurately specified with respect to required radial and lateral absorption of movement. This is, among other things, a result of the piping network calculations.
