Copper male threaded coupling,
Petroleum male threaded coupling,
ISO9001 metal coupling
Copper annealing male threaded Connect coupling used in Petroleum.
Threaded couplings refer to pipe connections with threads, which are the most common type of pipe fittings in industry and life.
The meaning of threaded coupling is: threaded joints make the connection of the pipeline easier, and it is easier to disassemble and replace, which greatly saves the cost of pipeline connection.
Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. A metal heat treatment process that heats the metal to a certain temperature, keeps it for a sufficient time, and then cools it at an appropriate speed (usually slow cooling, sometimes controlled cooling).
1) Reduce hardness and improve machinability.
(2) Reduce residual stress, stabilize size, reduce deformation and crack tendency;
(3) Refine the crystal grains, adjust the organization, and eliminate organizational defects.
(4) Uniform material organization and composition, improve material performance or prepare organization for later heat treatment.
In production, the annealing process is widely used. According to the different annealing purposes of the workpiece, there are many annealing process specifications. Commonly used are complete annealing, spheroidizing annealing, and stress relief annealing.
