HANGER FLANGE
These slim, easy to install units can be used anywhere in your Drilling or Completion/Workover BOP stack.
Academy Petroleum Industries Hanger Flange provides a safe means of hanging off a drill string or tubing where it is impractical to land the tubing hanger. This allows the tubular to be hung off at any point during the operation, no matter if the tubular is in the light or heavy position. These slim, easy to install units are readily adaptable and can be installed anywhere in your Drilling or Completion/Workover BOP stack.

The Hanger Flange is typically installed above or below the Annular or Rotating BOP between the stripline. It is manually activated by rotating the lag bolts. These units are especially useful when changing stripping elements while under balanced drilling. It is also useful when stripping on or off a snubbing unit while drilling, allowing the drilling rig to strip the drill string until the balanse point, before rigging in snubbing equipment.
- Low profile, compact design
- Three sizes available: 7 1/16" 5,000 PSI, 11" 3,000 PSI & 13 5/8" 5,000 PSI

- Academy Petroleum offers an optional inlay of Ring Grooves with Stainless Steel or Inconel
- Each unit comes with MTR's, Letter of Compliance and Pressure Test Certificates
- Academy's Hanger Flange can work for any application where weight of tubular strings needs to hang-off for any reason
- Academy Petroleum's Hanger Flange is by far the most superior hanger flange on the market
- Academy Petroleum also manufactures and sells various snubbing grippers and Blow-out Preventors for use on the snubbing rig
ACADEMY TYPE RS-100 TUBING STRIPPER
Academy Type RS-100 Tubing Stripper provides a safe and economical means for stripping long strings of tubing or drill pipe in or out of the well under pressure. The body and cap of the RS-100 are fabricated from high-strength steel for long, trouble-free service and economical operation and maintenance.
The RS-100 Tubing Stripper can be used in combination with an Annual Blowout Preventor for stripping long strings of tubing or drilling pipe under pressure. In this configuration, the annual BOP is operated only to seal off the wellbore in the event of emergency, or when passing oversized joints and hangers. By using the combination of an annular BOP and a stripper head, the point of seal can be transferred either above or below the oversized component. This eliminates the need to strip these through a closed unit.
The RS-100 Tubing Stripper comes with a 7 1/16 - 3000 or a 7 1/16 - 5000 bottom connector flange, with a maximum working pressure of 3000 PSI. They are hydrotested to 4500 PSI.

SNUBBING SLIPS
Academy Petroleum’s Snubbing Slips (also known as Snubbing Grippers) are used on a snubbing rig to securely hold the pipe being run in to or pulled out of the well. They feature a double acting hydraulic cylinder which will grip and release the pipe automatically when the control valve is operated by the snubber. Differing styles of slips are used to support either the weight of the pipe or the pressure load trying to push the pipe out of the hole. As well, some types of slips need to move with the pipe (travel) and some hold the pipe stationary while the traveling slips are repositioning on the string.
Academy Petroleum Industries manufactures several different types of Snubbing Slips to fulfill these various roles. These Snubbing Slips are used throughout Alberta, the Middle East and around the word.
Travelling Heavies
The Travelling Heavy version of the slips is pictured at right. They are intended to support the weight of the pipe and are mounted on the travelling plate of the snubbing rig so that they move up and down with the pipe. As they are the uppermost slip on the snubbing rig, and no additional equipment is mounted above them, Travelling Heavies are only supplied with a bottom flange to mate with the travelling plate and no upper flange.
Snubbers/Stationary Heavies
The Academy Snubber Slips are typically used in three configurations: a Stationary Snubber, a Traveling Snubber and a Stationary Heavy. The picture shows these slips in the stationary heavy configuration. There is a 7” bottom flange for mounting the slips directly to the top of the BOP stack, and a custom sized top flange for bolting on the stationary snubber. When used as a snubber (either stationary or traveling) these slips are inverted. For example, the traveling snubber would have the 7” flange on top for bolting to the traveling plate.
Dual Stationaries
The Dual Stationary version is used on snubbing rigs in order to minimize stackup height and weight. It combines both the Stationary Heavy and Stationary Snubber into the single unit. As can be seen in the equipment specifications table, this saves 6 1/2” of stackup height and 100lbs of weight.

ACADEMY - 7 1/16'' 5,000 TYPE 'S' API 16A MONOGRAMMED SPHERICAL BOP
Academy Spherical Blowout Preventors are a compact annular BOP designed to seal reliably on almost any size or shape of object in the wellbore (ex: drill pipe, kellys, casing and wirelines). They can also be used to maintain pressure control while stripping pipe into and out of the hole and they incorporate specific design features to suit snubbing applications. Academy BOPs were originally designed to withstand the rigors and harsh environment of the Canadian oilfield, but these rugged, reliable BOPs are now in service from China and Australia to the frozen Arctic.
Features
- Designed and monogrammed as per API 16A specification
- Simple, reliable design & construction:
- Only five major components
- Only two connections needed for Hydraulic System
- Wear rings are supplied on moving parts to maximize the life of steel components and seals

Design Principle
When hydraulic fluid is pumped into the closing port it fills the closing chamber below the piston, causing the piston to rise. The rising piston pushes on the seal element which then rides upwards and inwards on the spherical profile of the lid. As the sealing element is squeezed into the well bore, it will contact and seal on any size or shape of object in the well bore. If there is no object in the bore, the sealing element will continue to squeeze shut until it seals of the entire bore.

Principal of Operation
Hydraulic fluid is pumped into the closing port, filling the closing chamber below the piston, moving the piston upwards. The piston forces the seal element upwards and is guided inwards by the spherical profile of the upper housing. As the sealing element is squeezed toward the well bore, it contacts the tubular and seals off the annular area. Due to the flexible design of the seal element, it will seal on virtually any size or shape of object in the well bore. If there is no object in the bore, the sealing element will continue to squeeze closed until it seals off the entire bore.
