XUNDA PIPE COATNG TAPE 

System description:

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 dust, 
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 application, inner 
tape coating ,outer tape coating .
2.2 weather condition
2.2.1 When the wind&sand was strongly, when the sand and dust covered 
on the surface of pipe, primer ,tape etc., should not be brushing primer 
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.Brushing primer
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 brushing.
3.3 The primer should be applied uniformly, withou
