The present invention provides a simple fluid atomizer having a pair of spring loaded sealing elements such that the pressure required to open both seals is the sum of the spring constants of each of the sealing elements. A central cavity is sealed at both its entry and exit by moving elements held by coil springs. When the fluid in the entry channel is able to overcome a first spring, the first sealing element is moved so as to allow fluid to enter the central cavity. When the fluid pressure within the central cavity reaches a level necessary to compress the exit spring, the entry fluid pressure must be at a level for achieving the delta pressure across both entry and exit springs.

Atomizer

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.

Test coupon holder

A visual indicating device having an elongated slide valve mounted for longitudinal movement in a central bore of a housing. One end of the slide valve has a piston thereon mounted in a piston chamber and is responsive to a sensed fluid pressure in a flow line. The visual indicator is adjacent the other end of the slide valve and includes an outer fixed indicator element and an inner axially aligned rotatable indicator element. The outer fixed indicator element has a plurality of pie-shaped segments with alternate segments being transparent to permit visual viewing of the movable inner indicator element. The inner indicator element has a plurality of pie-shaped segments with alternate segments being of a green color and intervening segments being of a red or contrasting color. The altenate segments of the inner indicator element are axially aligned with the transparent segments of the outer indicator element in one position to present visually one color and the intervening segments are axially aligned with the transparent segments in the otherposition to present visually the contrasting color.
