Product Description

Product Description

The polished rod is manufactured from high quality alloy steel, which is high tensile strength, smooth surface and long service life. All of the polished rod is produced in accordance with API Spec 11B. The polished rod is mainly has two types: regular grade D polished rod and end upsetting polished rod. The regular grade D polished rods are connected by the polished rod coupling, and the end upsetting polished rods are connected to the sucker rod directly for usage.

There is another type of polished rod, which has ultra-high tensile strength, long stoke and corrosion resistant polished rod. This type of sucker rod is made of 20CrMo alloy steel. It is heat treated by quenching and tempering and the rod surface is metal sprayed with nickel-based alloy (Ni35) to make the rod be better resistance to the corrosion and

Features

1. Combined with packing set in packing box to seal wellhead and prevent oil,gas,water disclosure.

2. Interim connector between sucker rod and mule head hanger.

3. Finishing indicator diagram test.

4. Complete various wellhead operation, such as pump striking, regulating pump setting.
