APP 11B Standard High Quality Metal Spray Sucker Polished Rod For Oil Extraction
Products Descripition:
Polished rod is designed with the same function with sucker rod but used at the top surface of oilwell, it is also called polished sucker rod, as it come accross the stuffing box to join the downside sucker rod and horse head through bridle and clamp.All our polished rods are made of quality alloy steel and machined by advanced equipment and technology, with high strength, smooth surface and long service life. The tensile strength exceeds 1, 000 MPa (145, 000psi).
We can supply the folllowing kind of Polished rod:
1. Normal Type
2. One end diameter enlarged polished rod
3. high-strength, long stroke, corrosion resistant polished rod-
I. Using High Strength Steel
II. Surface Electroplating
III. Surface Spray Meta
Features:
Sucker rod Grad C series material is carbon steel or manganese steel,which is mainly used for light, medium load, no corrosion or corrosion shallow Wells or in deep well pumping. Grade D sucker rod is made of high quality alloy steel with heat treatment,It has the characteristics of high strength, good plasticity,long life and others, it is suitable for the environment which there is no corrosion or corrosive medium in the deep wells, Grade K level of sucker rod with different content of Ni Cr - Ni - Mo high quality alloy steel manufacturing, have anticorrosive, resistance to corrosion function, respectively applicable to the environment which are strong corrosion of shallow, middle and deep Wells.
