Abstract (en)
[origin: CA2713190A1] The invention relates to a method for production of anchor tubes (1), for injection anchors with a static mixer (6), positionally fixed in the longitudinal direction, wherein starting from a preferably hot-rolled tube (2), at least one static mixer (6) is inserted in the tube drilling (3) and then a profile (13) is rolled into the outer surface (4) of the tube (2) eine Profilierung (13), with at least local cross-sectional reduction of the tube drilling and the static mixer (6) is located in the longitudinal direction as a result of the cross-sectional reduction. According to the invention, an advantageous improvement can be made wherein a sleeve element (5) is introduced into the tube drilling (3) before rolling in the profile (13) which encloses the static mixer (3) in the tuber drilling (3) at least in a longitudinal section of the static mixer (6) and which has a lower hardness than the static mixer (6). The invention further relates to an anchor tube for injection anchors which may be produced by said method.
