    摘要： A pipe sealing apparatus (10), such as a split sleeve clamp, has a body (12) including a first body portion (14a) and a second body portion (14b), each comprising axially extending flanges (16a, 16b) having bores (18a, 18b) for receiving bolts (20) and nuts (22) to secure the body portions (14a, 14b) together. The apparatus (10) comprises a seal arrangement (24), a lock arrangement (26) and an actuation arrangement (28) comprising an actuation member (30) configured to both actuate the seal arrangement (24) and activate the lock arrangement (26). The lock arrangement (26) is carried by the actuation member (30) of the actuation arrangement (28).

    摘要： A clamp (10) has body portions (12) adapted to be secured together and a longitudinally arranged seal device (14) for sealing between the body portions (12). The seal device (14) is located in a groove (38) provided in an interface surface (39) of one of the body portions (12) and, in use, the seal device (14) provides sealing between the clamp portions (12).

    摘要： A method of isolating a section of pipe comprises locating a seal unit having two seal elements in a pipe via a penetration in the pipe, such as a branch or tee. The seal unit is then positioned in the pipe downstream of the penetration. The seal elements are activated using a primary activation mechanism to engage the pipe wall and then maintained in an activated condition using a secondary activation mechanism.

    摘要： A test tool assembly (10) for location in a section of pipe (12) comprises an isolation plug module (14) for isolating an upstream pipe section (16) from a downstream pipe section (18) and a test plug module (20) which permits a pressure test to be carried out on the upstream pipe section (16). The assembly (10) is configured so that a force acting on a seal arrangement of the test plug module (20) as a result of a test pressure applied in the pipe (12) is lower than a force required to maintain the seal between the seal arrangement and the pipe (12).

    摘要： An isolation tool (10) for isolating small bore pipe (P) has a spigot (12) having a proximal section (14) with diameter (D1) and a distal section (16) with smaller diameter (D2). A seal (18) is provided on the tool (10) around the smaller diameter section (16). In some embodiments, the isolation tool (10) is located through a hole (H1) in the wall of the pipe (P) and through a second hole (H2) in the opposite wall of the pipe (P), the tool (10) arranged so that when the tool is located through the second hole (H2) the seal (18) fills the bore (B) of the pipe (P) and isolates a section of the pipe (P). In other embodiments, the tool (10) may be located between severed pipe sections.
