发明名称 Water supply pipe, in particular floor heating pipe
摘要 Water supply pipe, in particular floor heating pipe, made of plastic having a diffusion protection sheath which is designed as a laminate and contains a lead foil. Thanks to the extensibility of the metal and its shear-resistant incorporation into the laminate, no reduction in the virtually complete diffusion blocking need be feared even with long-term cyclic loading.
