Chemical injection side pocket mandrels are used with the wireline retrievable chemical injection valves. The capillary tubing connects the pocket with the upper connector on which the NPT thread connects control line to surface injection pump. The chemicals are pressurized by the surface injection pump to enter into production pipeline.
Its orienting sleeve allows precise and proper alignment during the insertion of positioning devices / tools into the side pocket, Forged tool discriminator guides the proper diametern side pocket devicesltools into the mandrel pocket and defleets larger tools into the tubing bore to prevent damage to the positioning devicesltools.
In Gas Lift applications, high pressure gas injected into the casing annulus flows through the ports of the pocket in the gas lift valve andinto the tubing, The standard pocket is ported between the seal bores to communicate with the casing annulus and the gas is circulated down the annulus through the gas lift valve into the tubing. These mandrels are used for tubing flow applications.Both TMP and TP series feature multiple porting variations for specific applications i. e, annulus flow, chamber lift, fluid injection water flood installations.
