Detailed product description

Our factory can manufacture couplings, including sucker rod coupling, sub-coupling, API 5CT tubing and casing coupling. Sucker rod coupling and sub-coupling are designed in accordance with API Spec 11B, the material is high quality alloy steel. Normally, there are 2 wrench flats on the outside diameter. Class T coupling hardness is HRA56-62 after heat treatment, possesing better anti-corrosion property and abrasion-proof property.

 

Sucker rod coupling is used for connecting the same size of sucker rods. Sub-coupling is used for connecting the two sizes of sucker rods or polished rod to a sucker rod string.
