XUNDA PIPE COATNG TAPE
The XUNDA pipe Coating System is a multilayer system used for the
protection of steel pipelines.
The Anti-Corrosion inner layer is engineered to assure a high bond
to the primed surface with excellent conformability
characteristics. The mechanical protection outer layer , achieves a
complete bond to the inner layer, providing maximum handling and
in-service protection for the coating system.

Cold applied coating tape Application Instruction
1.Steel pipe pretreatment
1.1 Keeping the pipe external surface clean and dry. Remove the
oil, welding slag, burrs, grease and dirt on pipe surface.
1.2 Pipe surface prepared up-to a level of Sa 2 or 2 ½ or St 2/st
by sand blasting.
1.3 After the pre-cleaning operations, the pipe surface not smooth
which may sharp the pipe coating should be burnished , the abrasive
dust attached on the pipe surface should also be cleaned clearly.
1.4 If flash rusting occurs, the surfaces must be re-cleaned by
blasting as above.
2.Coating &Wrapping application
2.1 Coating &wrapping application consist of primer
tape coating ,outer tape coating .
2.2 weather condition
2.2.1 When the wind&sand was strongly, when the sand and dust
on the surface of pipe, primer ,tape etc., should not be brushing
and wrapping the tape if there is no reliable preventive measures.
2.2.2 When air humidity is greater than 80%,or when the pipe
surface is wet from any precipitation, should not be brushing
primer and wrapping tape.
3.1 The brushing time should be control within 6 hours between the
pipe surface treatment and brush primer. During brush primer, pipe
surface should be free from damp and pollution. If the pipe surface
rust return, should be re-pre-cleaned.
3.2 The primer should be mixed evenly in the container before
3.3 The primer should be applied uniformly, without any sags,
floods, runs, drips, bare spot and over spray, such as leakage
brush, clot, streaming. The primer coat DFT shall not be less than
3.4 After the primer dried, then wrapping the tape(It usually takes
3to 5 minutes.).
machine application approx. 0,1 litre/m²
hand application approx. 0,2 litre/m²
4.Wrap tape application
4.1 Wrap tape application consists of hand application and machine
4.2 The tape applied temperature must be above 5 degrees,the
coating construction temperature shall be more than -5 degrees as
4.3 The tape shall be spirally applied ,minimum overlap shall not
be less than 50%.
4.4 When a new roll of tape started ,the ends shall be located to
ensure the continuity of wrap tape using the same method of
4.5 Outer tape applied method is the same as above.
Cutbacks shall be a minimum 6inches(150mm) from the ends of each
pipe.The cutbacks may be tapered or straight edge for the total
of the coating.
