retaining rings. The system requires compressed air at approximately 6 to 8 bar. The compressed air gun is used to accelerate foam projectiles into the tube or hose to be cleaned. The plastic nozzles compress the inserted projectile, and also ensure that the connection is as airtight as possible, while creating a smooth transition into the tube or hose. This method is safe and environmentally friendly, and the operation is intuitive and quickly learned. The foam projectiles that carry out the cleaning are 15 per cent larger than the inner diameter of the tube or hose to

Stauff Clean offers a simple option for removing unwanted contamination in tubes and hoses for maintenance purposes. In addition, the system can be an alternative to time-consuming flushing processes during the production and processing of tubes and hoses. Stauff states that its system offers time and cost benefits compared to traditional cleaning methods. Stauff Clean essentially consists of a lightweight, ergonomically shaped compressed air gun, supplied with sufficient compressed air via a quick release coupling, and a range of specially shaped plastic nozzles that are connected to the handheld tool with

be cleaned. This creates friction that effectively releases contaminations.

In addition to a universal version that covers inner diameters between 6 and 60mm, numerous other projectile versions with different textures and grain sizes are available, eg for removing traces of rust and other coarse contaminations. The system can be used up to a tube/hose length of 100m, and regardless of any installed couplings, fittings and valves. For more than 50 years, the Stauff Group has developed, manufactured and distributed pipework equipment and hydraulic components for mechanical and plant engineering, as well as for service and industrial maintenance.

Flush system to provide increased through-bore The Duoline ® Flush System is an extension and natural progression of the Duoline DL System, which has been utilised in onshore and offshore wells worldwide over the last ten years. Using the same component material with an enhanced internal geometry, Duoline is now able to offer an increased through bore while still maintaining the benefits of the original Duoline DL Ring system. from corrosion from CO 2 , H 2 S, O 2 , chlorides and water, all or some of which may be present in the well fluid/ gas. Reservoir clean-up using HCL acid up to concentration of 28 per cent can be accommodated to ensure good flowrates.

shoulder premium connections without affecting the connections’ geometry and performance. The company can install the system into a wide range of diameters and weight bores, and can accommodate interventions with both coil tubing and wireline; procedures are already available for this operation.

Duoline may be installed into threaded oil country tubular goods (OCTG), either new or used, within most connection options. The Duoline Flush System employs the patented FL-Ring TM system, which permits lining of shoulder-to-
