sledgehammer's non welded bow spring centralizers are made under state of art engineering techniques and rugged quality system. They are developed to exceed api 10d specification for used under most demanding condition. These centralizers are designed for high restoring force and low starting & running force for centralizing the casing pipe in vertical, horizontal and deviated well.

premium quality bows are made of special double rolled alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over and good spring action. End collars are designed with self-locking action, which are easy to assemble, time saver and having strong grip. The five standard sizes bows can configure to any hole dia. These bows with extended profile prevent them from hitting against casing collars. These centralizers undergo a special iron phosphate coating process to prevent from rust and then coated with special polyester powder.

these can be shipped in half assembled condition for economical in shipping and storage costs. These are available in 4 1/2" to 20 " sizes. Any special sizes or combination can be made available on request.

ledgeHammer's Welded Spiral Vane Solid Rigid Centralizer Fixed is designed same as Welded Spiral Vane Solid Rigid Centralizer except rows of set screws on the outer periphery of centralizer to restrict rotation. It can be easily converted from fixed to non fixed design by detaching set screws and positioning with stop collars.

All centralizers are stored painted or coated with polyester powder. These are available in all sizes ranging from 3 1/2" to 20". Any special sizes can be made available on request.

The Canvas Cement Baskets consists of heavy duty canvas liners concentrated to staves and fabricated using high strength, flexible steel bows that are mounted on the steel slip-on end collar. The baskets are not duplicated and occasionally allow traveling the length of the joint to allow pipe movement. The cement basket has better ability to adapt to the bore hole and can accommodate larger than nominal hole sizes. The sizes are available for all kinds of hole sizes and standard casing. They are recommended for use in all kinds of standards casing grades.

Sledge Hammer Cementing plugs are manufactured of graded rubber that is fused upon a composite or Aluminum core. This top plug can be used when dual plug system is not required and Bottom cementing plug can be used when dual plug system is required. These plugs are completely PDC drillable. Operating range of temperature with Aluminum core is up to 200 degree Fahrenheit.

Plug can be ordered for higher operating temperature and operation in either synthetic or mud fluids.

SledgeHammer's Cementing Head is designed to hold a cementing plug before it is pumped down the casing during the cementing operation. In most operations, a bottom plug is launched before the spacer or cement slurry. The top plug is released from the cement Head after the spacer fluid. A manifold incorporated into the cement head assembly allows connection of a fluid circulation line.

SledgeHammer manufacture both type of Cementing Head, Single Plug or Double Plug and available sizes are 4 to 13 3/8".

The Hinged Spiral Nail Stop Collar comprises of two parts and hinged at two ends making an angle of 180 degree. This hinged Stop Collar has an internal groove and these are available in 4 1/2 " to 20 " sizes+ any sizes in which a spiral locking pin is inserted. This tightens the collar to the casing firmly.

It can be latched on the casing pipe without having to be slipped on. This cementing product is easy to install and most effective where annual low clearance received. The stop collars are coated with to polyester powder which prevents it from getting rust.

The SledgeHammer Float shoe supplied with plunger valve in most of the application. This design ensure positive sealing in vertical, horizontal and deviational wells. Material used for float equipment is seamless casing grade steel. Float equipment can be supplied in all grades of steel like K-55, L-80, N-80, C-95, T-95, and P110.

Traceability of component material starts from the mill material certificates; all machining of shoes is processed on CNC machines. SledgeHammer's Float equipment are tested and rated in compliance with API requires specs.

The material used in the valves is High polymer plastic and valve is consisting of Natural rubber coated on phenolic substance. This non metallic valve encased and held in place with the high pressure cement mixture. The design and manufacturing process of valve allow for maximum circulation rates.

SledgeHammer's Mechanical Stage tool allows cementing of casing string in two stages. These tool set the standard for reliability, cost effectiveness, and ease of use with outstanding built-in features and quality. They are the tools of choice when drilling requirements call for proven technology and low risk. The compact, simple design minimizes the number of moving parts and makes the tools easier to handle.

The tool's clear opening and closing indications at the surface accommodate the hydraulic conditions of the well for safer, more efficient operations. The internal sleeves increase reliability and prevent premature opening from formation restrictions on applied pressures. It reduces total pumping pressure in long casing strings.

Sledgehammer oil tools developed the bridge plug and cement retainer with their accessories. This tool is used for isolation of wellbore. There are the two types, either it will be permanent type or retrievable type. Sledgehammer has permanent type. It may be set by mechanically or hydraulically. This tool is easily convertible in bridge plug to cement retainer and vise versa.

Casing is large diameter pipe that is assembled and inserted into a recently drilled section of a borehole and typically held into place with cement. Casing used to Isolates different zones, that may have different pressures or fluids - known as zonal isolation, in the drilled formations from one another, seals off high pressure zones from the surface, avoiding potential for a blowout prevents fluid loss into or contamination of production zones, provides a smooth internal bore for installing production equipment.

Joint Keys are an another product of sledge hammer that id designed for the reason of economical cost of stabilizing and centering the pipe. They are available in several lengths sizes(specially designed radius on top and bottom of joints) as desired by customers. these are specially double rolled Alloy steels Bar.They are available in 2 7/8", 3 1/2", 4 1/2", 5 1/2" sizes For any hole combinations
