Oil well cement job on the car and mobile pump connection with detachable Swivel joint. Activities elbow by rapid disassembly connecting thread, rubber seals and guarantee that each pipeline is installed in the mine can move freely Swivel joint fittings (nominal diameter 60 mm) components.
Development of a new Swivel joint structure (see Figure). Features of the new structure are: sealing (especially in the 40-60 kg · force / square cm low pressure), the gap is very small. Ball track with a separate plug, racetrack opened five millimeters, thus reducing the elbow inclination.
The proposed ring shape avoids the mating surfaces when handling damage the seals between the shop under, and to ensure that the sealing ring has a pre-compression 0.3-0.5 mm during assembly.
Developed by the Swivel joint in line with modern technological level, its parts in mass production technology is good, therefore, equipment and tooling to manufacture these parts can be further improved, and mechanization and automation of the process.
Five new Swivel joint in 400 cement board tested. Within two years the unit for about 1,000 hours of work to complete a variety of jobs: cementing, fracturing, induce oil flow, squeeze cement. Nearly 100 times the various operations, each time. Under the force / cm pressure continuously in 30-350 kg 1-5 hours. All Swivel joint after 700 hours of work to change seals. All metal parts are still intact.
Well the process is completed during the operation did not find any damage to the sealing of the Swivel joint, the new Swivel joint without a monthly maintenance. In February-March after just work without disassembly of the coupling ball once lubrication.
The Swivel joint has developed into mass production.
