API 11B sucker rod coupling manufacture
Merchandise Description
Class T and Course EPT coupling for sucker rods are produced as per API Specification 11B.
Course T coupling use AISI 5140 to manufacture.
Class EPT coupling is utilized on the base metal.
The coupling is coated using phosphate chemical treatment method or blackoXiHu (West EPT) Dis.de on customer’s request.
The couplings are obtainable in entire dimensions, slender hole and in excess of size.
Mixture couplings are offered for different diameters for each Course T and Course EPT couplings.
