For successful injection, injection ports and mechanical packers are believed to deliver the best outcomes. A range of mechanical packers are available in the markets, which makes it simpler for a consumer to make a choice. Selection of a mechanical packer is made upon job requirements and project turnaround times.
Mechanical packers come in different designs, and vary in ball & valve locations, length, diameter, and packer material. Apart from the inventory available, a consumer can also have a custom mechanical packer made to be the best match for a job requirement.
Top variations among mechanical packers
Mechanical packers are primarily classified under surface mounted packers and insertable mechanical packers. Other prime classifications pertain to Packer type and materials, and packer body type.
Packers may be made from different materials, such as steel, aluminum, brass, different metal alloys and plastic. The design of packers depends on the application for which it is intended for use. Similarly, the design of a mechanical packer will also depend on the comfort level of the end user, and what a contractor thinks is the most suitable for a project.
Let us take a look at the advantages offered by different materials for making mechanical packers:
Steel is among the finest materials for making heavy duty mechanical packers. It is recognized for its strength and resistance to oxidizing components, particularly the kind found in acrylate or acrylic gels. In most cases, packers feature a rubber sleeve and large washer towards the top to facilitate installation.
Zinc, Aluminum and Brass
Packers made using zinc, aluminum, and brass are economic alternatives to steel packers, even while they feature the same functionality. They feature a lower tensile strength. In some cases, the packer need not be removed before patching. The shaft is broken off using a hammer and patching is done.
Plastic packers are available in an elaborate variety. A few of the plastic packers are advantageous because they facilitate a quick installation, high volume product flow and low resistance.
Flat button head injection packers
Zerk fitting is the most frequently used connecting mechanisms for packers. The other most frequently used arrangement is flat button head injection packers.
Zerk fitting is a preferred arrangement because it connects and disconnects easily. But a flat button head injection packer is preferred for high volume application. The connection quality is superior in the case of latter. It is also useful in the case overhead and single operator injection applications.
