ShengjiPetro 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 Polished Rod Clamp was awarded the utility model patent and design patent.
ShengjiPetro 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. ShengjiPetro oilfield rod clamp manufacturer according the requirement of customer can produce ShengjiPetro no-dent polished rod clamp that the nominal diameter and dimension accuracy are not standard. ShengjiPetro 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, ShengjiPetro oilfield 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.

Operation Manual
1). The nominal diameter of polished rod rated center bore should be the same as that of matching polished rod clamp.
2). The rated working load for polished rod clamp should be more than or equal to the needed polished rod load.
3). Before using, clean polished rod inner bore and oil stains on polished rod surface to guarantee that the surface is bright and clean.
4). During installation, polished rod clamp lower end should be tightly close to pumping unit carrier bar to avoid impacting when started.
5). If the viscosity of crude oil in oil well is too big, polished rod lagging down and occurs impacting phenomenon, our suggestion is to change bigger working load or use two polished rod clamp in the same type, the same working load together to increase working load. The two polished rod clamp ends should be closely tight when installation.
6). Two bolts should be fastened evenly for the two-bolt polished rod clamp.
7). Polished rod clamp bolt makeup torque
WL18200 type bolt makeup torque 1977N.m
WL16000 type bolt makeup torque 1545N.m
WL12000 type bolt makeup torque 3200N.m
8). Executive standard SY/T5029

1). The product was awarded two utility model patent and one design patent.
2). In accordance with the industry standards SY/T5029-2013 and API Spec 11B.
3). No dent, effectively reduce the damage to the polished rod and the packing of stuffing box.
4). Three models: WL12000，WL16000，WL18200. The product 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.
5). Can be used alone, can also be used with two same model and same load to increase the working load.
