API 11B Sucker Rod Coupling Sub Crossover
API 11B Sucker Rod Coupling Sub Crossover — Box x Box, Spray Metal Process
Product Overview
The API 11B Sucker Rod Coupling Sub Crossover is a critical connecting component used in oilfield sucker rod strings. It is designed to connect sucker rods of different sizes or thread types, ensuring a secure and leak-free connection throughout the rod string.
Manufactured strictly according to API 11B standard, this coupling sub crossover features a spray metal process on the surface, which significantly enhances wear resistance and corrosion resistance. The Box x Box design allows for direct connection between two box-end rods or couplings, providing maximum flexibility in rod string assembly.
