Product Description
-----------------------------------------
The 1-1/4 inch double stud polish rod clamp is a special matching component dedicated to fixing and positioning polish rods in oil production well workover operations, which can also be used as a temporary polish rod supporting tool. It can bear the polished rod load during the operations of polish rod replacement and fishing workover, prevent the accidental falling of the polish rod, and guarantee on-site operation safety.
This product adopts double-stud opposed clamping design, which provides more uniform clamping force and stronger structural stability compared with single-stud clamps. It is processed by integral forging technology, the main body is forged from high-strength carbon steel, and the clamping tooth surface is quenched and hardened, so it clamps tightly without slipping and will not excessively damage the surface of the polish rod. The whole product is treated with anti-rust hot-dip galvanizing, which can adapt to the outdoor open-air, underground humid and corrosive working environment of oil fields. Its wear resistance and corrosion resistance are excellent, and the service life is more than 30% higher than that of ordinary cast clamps. The product supports customization of special parameter specifications according to drawings, with sufficient conventional inventory. It will be shipped within 3 working days after payment, supports domestic distribution, and is conventionally packed in wooden cases for protection.
The product is widely applicable to production and workover operations of onshore oilfields and offshore oil production platforms, and can also be adapted to other pipeline fixing operation scenarios to meet the fixing and load-bearing requirements under different working conditions.
