Our Products #4674693

High restoring force for optimum standoff Low moving force to minimize drag Allow free rotation of the pipe for maximum displacement efficiency Over stop collar design minimizes moving forces while reciprocating Available Size: 4-1/2?x 6? and 7? x 8-1/2?. (Any special sizes or combination can available on request). They are shipped in assembled condition only.

HINGE TYPE WELDED SPRING BOW CENTRALIZER More Restoring force as compare to Non Weld Spring Bow Centralizer. Centralizers spring bow have strongly welded to the End Collar under required temperature and condition with extra low Hydrogen coated Electrodes. Integral hinge folded on the inside stay intact even under extreme stress. End Collars are designed with a Reinforcing Rib stamped into the End Collar to give maximum structural toughness. Available Size: 4-1/2? to 20?. (Any special sizes or combination can available on request). These are generally shipped in half assembled condition for economy in shipping and storage costs.

These centralizers are designed to give a minimum amount of drag resistance when passing through the previous casing or wellhead and then spring out to fit undreamed sections and washouts. Used for oversized holes The welded construction provides for superior strength over non-welded centralizers. High quality springs steel undergo consistency special heat treatment. Hinge installed around the casing O.D. Runs freely into difficult well-bores while providing excellent standoff. Available Size: 4-1/2 to 7. (Any special sizes or combination can available on request).

Designed for high deviated horizontal well where casing centralization is the main consideration. The SPIRAGLIDER system is made of steel, giving it a toughness advantage over other materials and alloys. Its Insured positive standoff, maximum flow, maximum well bore stabilization, maximum holding strength, decreased drag. Both spiral and straight fin designs minimize drag forces while running pipe. The fins glide smoothly on the low side of horizontal boreholes. Available Size: 3-1/2?to 13-3/8?. (Any special sizes or combination can available on request) They are shipped in assembled condition only.

Available in both Short as well as Long sizes. Specially designed with extra length to give maximum centralization. Straight Solid Centralizer is constructed of one-piece high strength corrosion resistance Aluminum, Zinc and Solid Steel. The innovative solid design ensures a fixed maximum stand-off regardless of lateral loads. They are design to provide optimum flow and its spiral blades overlap the entire 360-degree open hole circumference. They are not only self-cleaning going into the well bore, but the restriction of flow is less than most all other centralizers. Designed for use in highly deviated and horizontal wells and act as bearing during pipe rotations. Available Size: 3-1/2? to 13-3/8?. (Any special sizes or combination can available on request). They are shipped in assembled condition only.

Hinged Spiral Nail Stop Collar is combining in two pieces and hinged at two-end. The width of these stop collars is 63mm. This collar can be used in both upset and non-upset casing to provide maximum clearance during rotation. Locking is by way of a groove in the middle into which a spiral nail is driven for improved grip on the casing. "Available Size: 4-1/2? to 20?. (Any special sizes or combination can available on request).

Simple structure, easy to handle, defend leak effectively. The circulation is not restricted whenever in the process of running casing, during lifting and lowering or in the half way. Not infected by the temperature and causticity liquid. Can be used with relevant small casing. "Available Size: 4-1/2? to 20?. (Any special sizes or combination can available on request). These are generally shipped in assembled condition.

Slip-on centralizers are manufactured with solid end rings that can be easily slipped on the casing OD during installation. Operational and general design features are the same as Hinged Welded Bow Spring Centralizers. Available Size: 4-1/2 to 20. (Any special sizes or combination can available on request). They are shipped in assembled condition only.

O-rings are bi-directional seals, circular in shape and cross section. O-rings are generally made of an elastomeric material, but may be made of other materials such as PTFE or metal. An O-ring seals through the deformation of the seal material by installation and media pressure to close off the gap between mating components. Higher system pressures can cause deformation through the gap, known as extrusion, resulting in seal failure. Choosing a harder seal material or installing back-up rings to support the O-ring may alleviate this problem.

Plugs are used during cementing operations to help remove dispersed mud and mud sheath from the casing inner diameter and minimize the contamination of cement. A bottom plug is pumped ahead of the cement slurry and behind the spacer. It wipes any remaining dispersed mud from the inner diameter of the casing as it moves down the string. The top plug wipes center from the inner diameter of the casing and then seal at the float collar, resting on the on the bottom plug and causing a pressure increase at the surface including that the cement has been displaced. Top and bottom plugs are always different color. Bottom plugs are red and top plugs are black.

Slip-on centralizers are manufactured with solid end rings that can be easily slipped on the casing OD during installation. Operational and general design features are the same as Hinged Welded Bow Spring Centralizers. Available Size: 4-12 to 20. (Any special sizes or combination can available on request). They are shipped in assembled condition only.
