underground piping coating wrapping
underground piping coating wrapping is Cold applied tape coating
system for corrosion protection of Oil, Gas, Petrochemical, and
Waste Water underground or overhead pipelines.
This product has been made by a special processing of butyl rubber
to P.E. Its durability is strong and electric corrosion can be
prevented. The pipe can be semi-permanently preserved which has an
excellent effect on its corrosion resistance. It has a permanent
and continuous adhesion effect, this outstanding combination of
butyl rubber adhesion and P.E, make good weather resistance,
outstanding electric and chemical characteristics and good
workability for ease in both manual and machine work.
1) underground piping coating wrapping of water pipe, gas pipe, oil
2)coating wrapping of electric wire, voltage and communication
3) underground piping coating wrapping of pipe in chemical
factories having severe moisture and corrosion
4) underground piping coating wrapping of various pipe lines

How to use?
1) Pipe surface processing
thoroughly clean the surface of the pipe by removing all foreign
Completely remove any sharp projections from the area of the weld.
Remove all rust and/or other impurities using a steel brush.
2) Apply primer
Before application, shake or mix primer thoroughly.
Because it is highly volatile, make sure it is securely sealed
Because it contains inflammable solvents, use caution when working
near any open flames.
To obtain best results, apply primer in a temperature range of
0°C~25°C and for storage a
Temperature of -20°C~35°C is best.
Proper volume of primer is 100g per 1m².
When primer is applied and PE anti-corrosive tape is used, it is
recommended to apply the
tape within a short time after the primer is completely dry.
