ABSTRACT:
A pipe clamp used to support pipes of the type conveying dangerous materials -- e.g., steam pipes in nuclear installations -- especially where severe strains may be experienced -- e.g., seismic conditions -- is disclosed. The clamp has a yoke beam extending perpendicular to the axis of the pipe which is supported from a stationary support with an optional snubber interposed, the beam having a contact surface which fits against a portion of the pipe and a clevis or other means of attachment opposite the contact surface. The ends of the beam extend outward and have a "neutral" or "datum plane" surface tangent to the midpoint of the portion of the pipe engaged by the contact surface. Stabilizers extend axially of the pipe in either direction from the contact surface. Lugs on the pipe may be received in notches in the beam to prevent the pipe from sliding. A load bar extends around the pipe and is generally U-shaped, the ends of the bar being threaded and fitting through holes in the ends of the beam. Nuts on the ends of the bar bear against the beam at the datum plane. Preferably, a load strap of approximately the same coefficient of expansion as the pipe fits against the pipe and is slotted to receive the U-shaped portion of the load bar.
