The main function of a crossover sub is to connect the liner hanger assembly to the liner string. A crossover also provides a means of joining different sizes, weights and threads of casing and tools. Crossovers used in the string must have the same ID as the smallest ID of the string to insure the proper running of tools. Ferro-Tube ensures that all crossover subs meet or exceed the required metallurgic properties to withstand burst, collapse, and tensile strengths required by the end user. Ferro-Tube is an API 5CT licensed threader with strategic partners in the premium threading market.
Key features include:
• Allow a single product to cover a wide range of sizes
• The variation of weights reduces customer cost by minimizing inventory
