Parker’s Complete Piping Solutions programme starts with expert design advice and tubing pre-assembly and extends through to delivery and system installation. Developments in hydraulics are characterised by:
- Ever-increasing system pressures and safety requirements
- The sustained need to economise on installation
- Maintenance and operational costs and finally by the demand for compact, space-saving power units.
Our comprehensive service and advisory package offers great potential savings by enabling customers worldwide to profit from extensive services from one source.
Development and manufacture under one roof
Located in Augustdorf, near Bielefeld, close to Parker‘s European Logistics Center, the company’s Complete Piping Solutions Center (CPS) is the first operation of its kind in Germany. In the CPS Center, large format tube assemblies and flange systems are developed, produced and connected to complete systems in an area of 1,500 sqm.
Once released by the customer, the final design data is stored and subsequently can be immediately recalled for follow-up orders. Then on modern CNC bending machines in the CPS Center, tube outside diameters up to 220 mm are processed by cold forming for installation. Depending on requirements, bending radii of 2 x D to 3 x D are achievable. The finished and cleaned tubing systems are assembled and subsequently delivered to the Parker European Logistics Center nearby for onward shipment. Delivery direct to the assembly point and final assembly, complete with line testing, are all part of the overall program, as well as washing and final acceptance of the tubing systems.
Fewer operations versus classical welding
Parflange F37 system is the key. It was developed for tube lines from 16 up to 273 mm (½ to 10 inches) outside diameter and is suitable for pressures up to 420 bar. Depending on the application, the tube connector itself is manufactured by means of flaring or retaining ring technology.
In comparison with classical welding, the special orbital flaring process needs considerably fewer operations. The basis of the system is the well-proven Parflange technology by means of which a high-strength flared connector with a rolled, compacted tube end surface is produced, positively locking the tubes with each other. Stress corrosion cracking cannot occur, thus prolonging the life of the tubing system. Parflange technology also saves energy since it operates without external heat supplies.
Neither degreasers, anticorrosive agents nor subsequent tube cleaning are required. When galvanised tubing is being used there is no need for post-galvanisation because the zinc layer is not affected by the flaring process. No harmful vapours occur during flaring or assembly and there is no risk of fire or explosion. This means that the technology can also be applied in workplaces with stringent safety regulations such as oil and gas offshore platforms.
Alternatively, the Parflange 170 machine is also available for absolutely smooth, fold-free flaring, as part of the Parflange F37 system. The remarkably short cycle time – only one to two minutes for total machining depending on tube quality – makes considerable productivity advancements compared with welded piping systems.
A complete solution from beginning to end
Many projects can be completed in considerably less time with Parker’s Complete Piping Solutions technology. In the CPS Center customers utilise the expert knowledge of Parker’s systems engineers and technicians and thereby reduce their own design expenditure and ultimately increase their productivity. Without internal friction and coordination problems, machinery and plant builders’ time is freed up for more important tasks. With its Complete Piping Solutions system, Parker is able to partner with its customers to develop high quality hydraulic systems quickly that require less maintenance over prolonged lifespans.
