A casing bolt (1) for a pipe (20) provided with at least one flaring (21) comprises a metallic base body (10) accommodating the pipe (20). The sleeve bolt (1) further comprises a bolt head (12), a threaded section (13), a contact section (15) designed to abut against a flared opening (21) of the pipeline (20), and a functional layer (40) applied to the main body (10) at least in the region of the threaded section (12) and the contact section (14). The functional layer (40) is multi-layered and consists of at least a bottom layer (41) and a top layer (42) which is at least partially applied to the bottom layer (41). The bottom layer (41) forms a structure to produce an anticorrosive coating and a high degree of invariance with respect to the material of the commonly used friction partners of the sleeve bolt (1), which structure, in addition to the adhesive, contains zinc in the form of a zinc-containing sheet layer (43) oriented substantially flat on the base body (10).
一种用于设有至少一个扩口(21)的管道(20)的管套螺栓(1)包括容纳管道(20)的金属基体(10)。所述管套螺栓(1)还包括螺栓头(12)、螺纹段(13)、设计为抵靠管道(20)的扩口(21)的接触段(15)以及基体(10)至少在螺纹段(12)和接触段(14)的区域中涂覆有的功能层(40)。功能层(40)呈多层并至少由底层(41)和至少部分地施加到底层(41)上的顶层(42)组成。底层(41)形成了一种结构,以产生防腐涂层以及相对于管套螺栓(1)的常用摩擦副材料的高度不变性,除了粘合剂之外,该结构还含有含锌片层(43)形式的锌,该含锌片层定向成基本上平放在基体(10)上。
