How BPI tape is applied
Four operations: clean, prime, wrap, inspect. The wrapping method depends on the shape of the part.
KM 01
Order of work
- 01
Cleaning
The surface is cleaned with scrapers and brushes to grade 4 of VSN 008-88 (for gas pipelines).
- 02
Primer
An even layer of primer is applied by roller and brush to the cleaned, degreased surface.
- 03
Wrapping
On straight runs with the wrapping device; on joints and fittings by hand.
- 04
Inspection
Coating thickness, adhesion and continuity are checked.

Two ways of wrapping
| Wrapping device | By hand | |
|---|---|---|
| Where used | Straight runs of pipeline | Joints, tie-ins, bends, fittings, spot repairs |
| What it gives | Constant overlap and tension around the pipe, high output | Work on complex geometry; light fusing of the mastic is permitted |
| Device weight | Up to 100 kg for a 1200 mm pipe | — |

Questions and answers
Where are the overlap and layer requirements?
In the document "Requirements for coating structures using BPI tape", which can be downloaded on this page.
Can the tape be applied on a live gas pipeline?
Yes. The tape is not heated near the works, and the light wrapping device keeps the load on the pipe to a minimum.
