Product Description

Crossover sub is used to describe a mechanical component with threaded connections.Its used to connect components with different sizes
or thread types.
Crossover subs are most often found in the drill pipe between the drill pipe and drill collars, as well as at other locations throughout the drill string.
These components let the driller modify installations according to their field conditions.

The uses of crossover subs:
Crossover subs typically provide the connection between drill pipes and collars. They are designed with a box and threads, When two threaded components are joined, one end of the crossover sub is built to match the thread pattern of one of the components to be joined
and the other end is built to match the thread pattern of the second component, Drill rigs generally include a wide range of crossover subs and operators utilize them as needed to join disparate parts.The subs' threaded connections are protected by a layer of phosphate-coated material that prevents galling during the initial make-up. subs are manufactured according to the specifications that are provided by the American Petroleum institute APl. What is the importance of a crossover sub?
Crossover subs are an important part of any drilling operation Crossover subs are an important component of every drilling operation as they provide the flexibility to adapt the drill string to the specific requirements of the well-being drilled. They are also used to repair damaged sections of the drill string and to connect dissimilar parts of the drill string. Crossover subs play a vital role in ensuring the safe and successful completion of drilling operations.Crossover subs are primarily the devices required for oil rig drill strings According to the demands of clients or the specific job in question,  Subs are equipped with a side port or an inline port to assist in the circulation of fluids. The majority of the connections are cut to meet safety and ground requirements. They're made from heat-treated steel for greater strength and durability.Crossover Subs are primarily used for several purposes

Crossover subs are used to transition from a single connection to another. These components are also utilized to extend the life of more expensive drill stem components, Crossover subs are available in the different forms, in the following types of configurations, connections on subs are available in three variations:
The Box- box
Box- pin
Pin- pin
Standard and premium crossover subs Superior Performance has standard crossover subs and premium crossover subs available, These short sub assemblies used to connect components of different sizes or with different threads are essential when linking casing to other connections or to drill pipe.Superior Performance carries crossovers ranging in size from 2 3/8 inches to 20 inches in various connection options. Additional sizes and connections can be special ordered. Most of our subs are for casing and tubing.

***
The length of crossover subs is generally measured from shoulder to shoulder. Typical lengths range from 6" - 28" long going up in increments of 2 inches with AISI 4145H, AISI 4145H Mod, AISI 4340, AISI 4140-4142 and Non-magnetic material. All connections are phosphate-coated or copper-plated to improve resistance to corrosion. Crossover subs come in three basic types: A Pin (male) * Box (female); B Pin (male) * Pin (male); C Box (female) * Box (female)
