EN 2608:20054 1 Scope This standard specifies the installation and removal requirements for adaptors, threaded, with lockring for pipe couplings 830 according to EN 2603. This standard establishes an accurate p
20、rocedure of adaptor installation, removal and reinstallation to ensure the repeatability of the installation operation and to ensure the effective compliance to sealing and locking re-quirements. The adaptor shown on all figures of this standard is given as an example for the 830 interface according
21、 to EN 2604. This procedure is used for adaptors 830, for nominal pressure up to 28 000 kPa to install the adapters according to EN 3248, EN 3270 and EN 3566. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、e made according to EN 2602. Special broaching tool can be used as shown in Figure 4 and Table 4. In this case the following procedure shall apply: 1) Prior to broaching, the cutter teeth will rest on the surface of the boss and the body of the tool will be free to move up and down. Note that the nu
43、t should be backed away from the body of the tool. 2) The tool may be hand-held or used under a press. 3) Locate broaching tool pilot into the port. 4) Slowly apply a force to the mandrel while holding the body to allow the teeth to broach into the parent material counterbore. 5) Broaching is comple
44、te when the external shoulder of the mandrel contacts the internal shoulder in the body. 6) The installation force is then relieved and the tool is ready for removal. 7) To remove the tool from the boss, turn the nut in clockwise direction against the body and the man-drel will move the cutter up, a
45、way from the port counterbore. Table 4 Serration tool Dimensions in millimetres d7cd8l5cs1c,dt1c830 coupling CodeaPort dimension code Tool Part No.bEN 0,4 Ref.
