The Hydraulic Access Fitting Assembly consists
of an access fitting body with locking pins, a solid or hollow plug, and a protective cover.
The access fitting body is manufactured from A350-LF2 as standard; however, other materials are available. The Flareweld fitting has a radius
to allow it to conform to the profile of a pipe or vessel, and the flared end has a large surface area to allow for a strong weld joint, and provides
ample reinforcement material for the branch
connection. Flanged end connections are also available which conform with ANSI or API
specifications. Each access fitting body is
supplied with four locking pins, which are
designed to hold the solid or hollow plug in
place during retrieval operations. These locking pins are supplied in 17-4PH Stainless Steel with FKM O-Rings as standard, but other materials are available

Non-Tee fittings are standard for use with
standard corrosion monitoring devices. Tee-type fittings for injection and sampling applications are also available. These tee-type fittings are available with standard NPT threaded ports, or with integrally attached side tee flanges for connection to injection/sampling piping.
Solid plugs are available for attachment of
corrosion monitoring coupon holders or injection tubes. Refer to the ‘Hydraulic Solid Plug
Assemblies’ datasheet for details and ordering information. Hollow plugs are available for
attachment of corrosion monitoring probes.
Refer to the ‘Hydraulic Hollow Plug Assemblies’ datasheet for details and ordering information.
Protective covers are required, and are designed to hold the solid/hollow plug in place after installation. Covers are available which provide secondary pressure retainment for enhanced safety, or non-pressure retaining for
holding the plug and protecting the access fitting from damage. Refer to the ‘Hydraulic Protective Covers’
datasheet for details and ordering information.
