7.9. MASKING

The bevel of each spool shall be masked to a distance of 50 mm from the bevel prior to

painting. This also applies to bevels in the field where the piping is painted prior to completion of the welding. The masking of stainless steel requires special chloride free tape which will be approved by Linde/PMC.

The Painting Supervisor shall also ensure that the piping identification is maintained

prior to and after painting. This also applies to the straight run pipes.

The Painting Supervisor shall ensure that there is no overspray onto previously painted surfaces or beyond the application area. If there is danger of inorganic zinc primer overspray contaminating stainless steel then the stainless steel shall be protected by suitable means i.e. masking, covering with polythene etc.

After completion of painting all masking shall be removed and any overspray, dry spray

etc.

The GAMA Qatar Quality department shall perform surveillance inspection to ensure proper masking protection is applied.

Masking shall be applied before blasting and coating operations to protect the gasket

surfaces (except plain face) and the pipe or nozzle interior. Surfaces that will be inaccessible after assembly including the surfaces of lap joint, flanges, nozzle necks, bolt holes shall receive the complete painting system before being assembled, steel structure bolted connections shall be primed only unless otherwise noted.

The outer edge of ring groove flanges and raised face flanges will be blasted and coated

to the upper (outer) edge of the ring groove or the outside edge of the raised portion of the flange. The entire groove area shall be protected.
