API 11B Single Bolt Polished Rod Clamp

API 11B Single Bolt Polished Rod Clamp

Shengji no-dent standard polished rod clamp is manufactured strictly in accordance with Oil and Gas Industry Standard of People’s Republic of China SY/T5029. The standard is equal to international standard ISD 10428 and API Spec 11B. The product was awarded the utility model patent and design patent. Shengji no-dent standard polished rod clamp is suitable for the standard polished rods that the nominal diameters from 22mm to 38.1mm, which can meet the requirements of different pump depths, polished rod sizes and loads. Shengji oilfield rod clamp manufacturer according the the requirement of customer can produce Shengji no-dent polished rod clamp that the nominal diameter and dimension accuracy are not standard. Shengji polished rod is no dent, can effectively reduce the damage to the polished rod and the packing of stuffing box. If the viscosity of crude in the well is high, and the impact happens due to the down stroke lag of polished rod, Shengji polished rod clamp manufacturer recommends to change a clamp of larger working load or use two clamps of same model and same load to increase working load.
