When installing on welded pipes
- First the risk-point should be covered with a double layer of wide sheet of the MF01 tape (Step 1a).
- Next - the separate pieces of the 5 cm or wider tape should be installed from the central point to the both sides in a spiral motion which will enable to direct the leakage beyond the installed tape. Each separate layer should overlap the preceding one at least by 50% (Step 2a and 3a).
When installing on Flanges, Valves and other specially shaped equipment
- It is advisable to use the MF-01 material available in sheets or in rolls with its width corresponding to the dimension of the protected element (Step 1b).
- When installing the tape on flanges its width should cover the entire surface of the flange and a minimum of 100mm on both sides of the pipe joint. This is required to ensure enough adhesive surface strength in case when high pressure expands installed material. (Step 2b).
- The length of the material should be selected in such a way as to ensure that the areas where the tape is applied are covered by at least two layers of the tape.
- Next - the separate pieces of the 5 cm or wider tape should be installed from the central point to the both sides in a spiral motion which will enable to direct the leakage beyond the installed tape. Each separate layer should overlap the preceding one at least by 50% (Step 3b).
- In cases where the protected pipe is directly connected to a valve, the valve should also be entirely wrapped in the Antispray MF01 material keeping in mind that two layers of tape should be applied.
