Wanja Galewsky & Ramiz Selimbasic introduce a range of new services with multiple benefits for pipeline operators

aluable new services from a single supplier have recently been brought to market to enable users in the oil pipeline sector to increase their flexibility and benefit from cost
advantages. Before these new services came the Parflange system developed by Parker, which continuously flares and then flanges the tube during its cold- forming procedure. Since its introduction, it has proved highly effective with regard to mechanical strength and long working life. Furthermore, this method is 9 to 12 times faster than comparable welding. On top of this, cleaning the tube before and after the manufacturing process is not necessary. Te Parflange process is always environmentally friendly since no dangerous gases occur, like they do with welding and brazing, and heating up before the manufacturing process is also not necessary. It was from this technology that the Parflange F37 system was developed, enabling tubing systems of various sizes to be connected to each other. It uses the orbital tube forming technology for tubes from 16 to 273mm outside diameter and is intended for wall thicknesses up to 9mm and pressure ratings up to 420 bar. For connections in which no pre-formed tube can be assembled, the F37 retaining ring system is available. Here the flange is held on the tube by a retaining ring that, together with a high- tech seal carrier, ensures leak-free connections. Te Parflange F37 system offers distinct
advantages compared with classical welding; the preparation time per tube-end is shorter and the not inconsiderable costs for cleaning the tube and checking after welding are quite simply not required. Also, the tube connections show constantly high quality and accuracy. As a result, installation times are shorter and the project time overall is also shorter as well. As part of the Engineered Services initiative,
Parker has developed its Complete Piping Solutions (CPS) system. It has been put together from several modules such as consultation, piping layout, pre- assembly, delivery and installation, from which the customer can create a tailor-made concept for the manufacture of piping systems or, when required, can make use of all the above-named services.

Now, the concept is being extended with two additional modules. Parker Onsite Containers were developed, amongst others, for service in the offshore and shipbuilding sectors. Tey contain all the assembly machines that are required for preparing the assembly of tubes from 6 to 60mm diameter. If required, much bigger tubes with outside diameters up to 273mm can also be prepared.
Te range of high-precision machines covers all the fittings and connectors supplied by Parker, such as high-performance flanges and the EO-2 soft- sealing fittings system. Common to all of them are the consistently good assembly results. Furthermore, Onsite Service Containers include complete equipment for the installation of tube lines, such as forming, bending, cutting and cleaning machines. Te contents of the container can be made up according to need and actual requirements on site. In addition to this, the service offering has been extended to include Parker hot oil flushing units. Tey clean the tubing system before they are connected to the main consumer. Te system flushing increases the safety of the complete
The CPS enables the customer can put together a tailor-made concept for the manufacture of piping systems
