Inflatable Bridge Plugs
IPI design and manufacture a range of inflatable bridge plugs which provide a permanent plug with the advantages of small relative run-in diameter, large setting range and the ease of installation which is typical of IPI inflatable packers.
These bridge plugs were specifically designed for plugging of wells prior to abandonment as part of usual cementing procedures.
Features include:
• Suitable for setting in open hole or casing.
• Available
to suit standard casing sizes of 13 3/8” and 30” diameter.
• Factory set spring check and relief valve systems assure positive
pressure shut-in and prevent over-inflation.
• Shear valve inflation protection
system to prevent premature inflation.
• Lifting points provided on both ends of
all plugs to facilitate handling.
Although normally use din conjunction with a cement grout plug set on top of the packer these bridge plugs can also support considerable differential pressure unsupported from either above or below.
Standard Plugs
The standard range of plugs are principally designed
for setting in casing. They employ a fixed end inflatable packer element
with synthetic cord and steel wire reinforcement. Specifications for

Large Expansion Plugs
These plugs are originally designed to enable running
through BOP restrictions and set in larger diameter casing.
Owing to
their large expansion capability they are also useful for open hole applications.
They employ a sliding end, fully steel wire reinforced, inflatable packer
element.

IPI have recently developed a unique open hole bridge plug.
This plug uses a fixed end inflatable packer element that combines full length slat reinforcement to offer higher temperature and pressure integrity with IPI’s standard synthetic and wire reinforcement system.
The standard tool is 168mm (6.614”) OD with an element rubber length of 1500mm (59”). It is designed to set at 1000psi in up to 254mm (10”) diameter open hole and support at least 7000kg (15,000lbf) in either direction.
Other sizes and capacities are available on request.
