摘要： A screw joint for pipes, in particular sanitary and floor heating pipes of, for example, plastic material or a composite material of metal and plastics is provided with at least one screw joint member with a substantially cylindrical portion, in which a thread with at least one helical raised portion of, in particular, triangular cross section is formed. The at least one raised portion of the thread has a base section adjoining or located in the cylindrical portion and an end section radially adjoining the base section. Within at least a part of the course of the thread, at least the end section of the at least one raised portion is made of a material that is more elastic than the material of the cylindrical portion.

摘要： A pipe fitting comprises a fitting body with a longitudinal axis, having a pipe connection member for the sealed connection of a pipe and a thread for threadedly joining the fitting body to a connection unit, and a member on the fitting body to be driven by a tool, to which a tool for turning the fitting body about its longitudinal axis may be applied for threadedly joining the same to the connection unit. This fitting is provided with means between the tool engaging portion and the fitting body that limit the torque acting on the fitting body when the tool engaging portion is turned.
