Haige provide offers a complete range of couplings for sucker rods, polished rods, sub couplings. They are available in reduced slim hole (SH) diameters, normal full size (FS) for both API (Class T and Spray Metal SM) and high strength versions (UHS).
Spray Metal is a superficial hardening process in which a nickel, chrome, boron and silicon based powder is applied on the base metal and later melted, resulting in a hard, dense and uniform surface with a very low friction coefficient and high corrosion resistance.
