The coupling blanks are manufactured or machined to the required dimensions and tolerances. They are then threaded using a cold-forming rolled thread tap and given a coating to enhance their anti-galling and lubrication properties. For applications that do not involve abrasion or corrosion-abrasion issues, it is recommended to use class T sucker rod couplings during installation.
Sucker rod couplings are offered in both API full size and slim hole configurations. Upon request, oversize couplings can also be provided.
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.
Class SM sucker rod couplings are recommended for installation where abrasion or corrosion-abrasion is a problem.
Sucker rod ouplings are available in API full size and slim hole. Oversize are available on request.
