                Subpart D--Design of Pipeline Components
 
Sec. 192.161  Supports and anchors.

    (a) Each pipeline and its associated equipment must have enough 
anchors or supports to:
    (1) Prevent undue strain on connected equipment;
    (2) Resist longitudinal forces caused by a bend or offset in the 
pipe; and
    (3) Prevent or damp out excessive vibration.
    (b) Each exposed pipeline must have enough supports or anchors to 
protect the exposed pipe joints from the maximum end force caused by 
internal pressure and any additional forces caused by temperature 
expansion or contraction or by the weight of the pipe and its contents.
    (c) Each support or anchor on an exposed pipeline must be made of 
durable, noncombustible material and must be designed and installed as 
follows:
    (1) Free expansion and contraction of the pipeline between supports 
or anchors may not be restricted.
    (2) Provision must be made for the service conditions involved.
    (3) Movement of the pipeline may not cause disengagement of the 
support equipment.
    (d) Each support on an exposed pipeline operated at a stress level 
of 50 percent or more of SMYS must comply with the following:
    (1) A structural support may not be welded directly to the pipe.
    (2) The support must be provided by a member that completely 
encircles the pipe.
    (3) If an encircling member is welded to a pipe, the weld must be 
continuous and cover the entire circumference.
    (e) Each underground pipeline that is connected to a relatively 
unyielding line or other fixed object must have enough flexibility to 
provide for possible movement, or it must have an anchor that will limit 
the movement of the pipeline.
    (f) Except for offshore pipelines, each underground pipeline that is 
being connected to new branches must have a firm foundation for both the 
header and the branch to prevent detrimental lateral and vertical 
movement.
