An assembly for insertion of an object into a pipeline comprises a base, a connector, and a set of pins. The base has a cylindrical passage and is connected to a mechanismforconfigured to drive the object into an inlet in the pipeline. The connector includes a head and a cylinder with a threaded internal surface andaanexternal surface having a groovespanning aextending around thecircumference of the external surface. The connector is rotatable within the cylindrical passage in the basein a first directionandisheld substantiallyaxiallystationary within the cylindrical passage in the basein a second directionby the set of pins in cooperation with the groove.The base is rotatable in the first direction and held substantially stationary in the second direction while connected to the inlet in the pipeline by the connector.

A cartridge seal for centrifugal pump comprises a shaft tube assembly attached to a structure. A shaft tube of the shaft tube assembly receives a shaft of the centrifugal pump. A shaft collar of the cartridge seal attached to a second end of the shaft tube is in communication with a second end of the structure. A chamber tube of the shaft tube assembly and the shaft tube collectively define a chamber that contains compressed gas. A spring is located in the chamber of compressed gas. The compressed gas and the spring cause the shaft tube assembly to substantially prevent movement of fluids between the shaft and the structure in the centrifugal pump.

A packer joint is provided for mounting on a vessel or pipeline entry valve which includes a stinger guide and seal. Clamping collet are mounted within the packer to retain the stinger in the desired position. Different metals within the guide body from those of the stinger rod prevent gaulding and damage. A lock-up the rod may be released via a bore hole providing tapping access to the collets.

Vessel and pipeline insertion tool

A packer joint is provided for mounting on a vessel or pipeline entry valve which includes a stinger guide and an adjustable packer seal. A driving mechanism is mounted on the packer joint to which the stinger is connected for insertion through the packer joint into the vessel or pipe line. Improved clamping collets are mounted within the packer joint to retain the stinger in the desired position after insertion. A safety cap is provided for mounting on or around the packer joint and exposed end of the stinger after the stinger is inserted and the driving mechanism removed.

A corrosion coupon holder for inserting and removing a coupon from the interior of a pipeline while under pressure has an elongated housing with a threaded connection at one end and a removable closure device at the other end, the housing connection to be attached to a pipe entry valve which is connected as a branch to the pipeline. The housing other end also carries a guide body having a bore which guidingly and sealingly receives a rod for inserting a coupon having a safety stop element at one end to hold the coupon, the guide body having a split collet associated with the bore with a locking screw mounted to act on the collet to fixedly clamp the rod in the bore of the guide body and the housing having a bleeder valve communicating with the interior to relieve pressure from within such interior.
