Internal (I.D) & External (O.D) Surface (or API Threads) Shot Peening in Rotary Shouldered Connections / Pipes / Drill Collars.
SURFEX® designs and manufactures the Shot Peening M/c for Oil & Gas Industry (For Internal (I.D) & External (O.D) Surface (or API Threads) Peening in Rotary Shouldered Connections / Pipes / Drill Collars.).
To generate the controlled compressive stress to the surface (near – surface region) and to enhance the surface properties (increase the fatigue strength), the job surface will be pounded by spherical peening media to create small indentation, which increases the life of components.
Controlled Shot Peening is regularly being specified by the oil and gas industry to enhance component service life (by better fatigue performance). It is a cold working process in which the surface (internal & external) of the job (being processed) is bombarded (or pouned) with spherical peening media. The compressive stresses induced by shot peening can considerably increase component service life (by better fatigue performance) and move the job into a higher cycle fatigue regime.
Process consistency in the shot peening process is vital, and the “SURFEX” machines are custom designed to control all the critical variables to suit the applications.
SURFEX® equipment includes a fully automatic Dust Collection System to remove dust and fines from the peening chamber.
