Couplings are manufactured from quenched and tempered micro alloyed steels.API couplings are furnished in two classes: Class T and Class SM (Spray Metal). The later has a superficial hardening process (based in nickel, chrome, boron and silicon) that provides better erosion and corrosion resistance. This coupling is also recommended Slim Hole (SH) couplings when required due to the tubing internal diameter limitations.
