Abstract: A safety handle for use with conventional pipe tongs. The safety handle has a hand grip, as well as upper and lower flange members. The flange members beneficially define a recess for receiving (and protecting) a user's thumb. At least one attachment cavity is provided for receiving, and securely attaching the safety handle to, a tong jaw member.

Abstract: Manual pipe tong comprising secondary latch. The pipe tong comprises a handle and a plurality of linked jaw segments pivotally attached to the handle. Two of the segments are first and second latch segments, and are releasably engageable to form a primary latch. The primary latch may be released and the jaw segments opened to encircle a tubular for makeup of a threaded connection. The first latch segment comprises substantially parallel upper and lower surfaces, and projections on each of those surfaces. A hooking member on the second latch segment comprises a pair of spaced-apart hooks joined by a handle, and is rotably disposed on the second latch segment so that the hooks sandwich the second latch segment. The hooking member is rotatable between first and second positions, and in the second position the hooks engage the projections on the first latch segment so as to form a secondary safety latch.

Abstract: A pig valve for use with a pigging system of a pipeline has a body insertable into the pipeline and provided with a hollow interior which forms a straight passage through the body. Rotatably disposed surrounding the body is a sleeve having associated therewith an access arrangement for permitting a pig to be transferred between the passage and outside of the passage for launching and receiving the pig. Whether the valve is used as a launcher or receiver depends only on the orientation of the valve relative to the associated pipeline, and on provision of a deflecting grate in the valve employed as a receiver. The sleeve is arranged for rotating about the longitudinal axis of the straight flow passage of the valve body so as not to interfere with fluid flow through the pipeline.
