SRI realized an extraction column for component extraction from oil. We manufactured the entire column from Duplex. The build included all internals as well as platforms. After the pressure test we completely insulated the column in our workshop.

Engineering, manufacturing and assembling an oil extraction column.

Concept and engineering

First we translated all data sheets with our customer’s requirements demands into a GA drawing. We then we made a detailed drawing with welding details in accordance with the EN 13445 design code. Part of the design was performing wind-load calculations.

Realization and development

Before starting production, our independent QC department draws up an ITP (inspection and test plan). Based on the ITP, we set up a PIM (pre-inspection meeting) with our customer. Our project office then draws up a detailed plan, which we share with our customer.Read more


Construction and installation

Based on our various drawings SRI starts production. Parts are rolled and welded (under powder deck) and tube sheets are drilled. Our QC department strictly adheres to the ITP, guaranteeing end quality. After the various parts have been manufactured, we assemble the column.Read more


Service and maintenance

After approval we lift the extraction column according to an approved lifting plan and then transport it to our customer. Our assembly team takes care of unloading the equipment and installing it in the factory Read more
