How many kinds of Water steel pipe corrosion protection coating ?

 

There are mainly 7 types coating and wrapping methods for the water steel pipe.

6.LIQUID-EPOXY COATING SYSTEMS FOR THE INTERIOR AND EXTERIOR

7.PETROLATUM AND PETROLEUM WAX TAPE COATINGS FOR THE EXTERIOR OF CONNECTIONS AND FITTINGS

 

We JINING XUNDA PIPE COATING MATERIALS CO.,LTD can supply the materials for the Item 2 HEAT-SHRINKABLE CROSS-LINKED POLYOLEFIN COATINGS , Item 3 COLD-APPLIED TAPE COATINGS , Item 7 ETROLATUM AND PETROLEUM WAX TAPE COATINGS FOR THE EXTERIOR OF CONNECTIONS AND FITTINGS

 

Here we are talking about for the Item 3 Cold applied tape coatings.

 

There are three layer at least for this coating system

1. A solvent-based or 100 percent solids-liquid adhesive layer

2. An inner-layer tape for corrosion protection.

3. An outer-layer tape for mechanical protection.

 

Here the inner-layer tape thickness should be 20 mils ( 0.50 mm ), the outer-layer tape thickness should be 30 mils (0.75 mm). inner-layer tape is black color, the outer-layer tape can be gray or white color .

The tape width will be confirmed according the diameter of steel pipe. The mainly width is 50 mm, 100 mm, 150 mm and 230 mm

 

How to confirm the length of wrapping tape in roll ?

 

It depends on the application methods, if manual application, we suggest the length more short a bit , such as 100 ft, 200ft, 400 ft. If one roll is too heavy, it is not easy for wrap it by workers without machinery. But if there is coating division to wrap the tapes, the hot length is 1000 ft, the inner wrapping tape outer diameter is about 50 cm in roll for inner wrapping tape, the outer wrapping tape outer diameter is about 60 cm in roll.

 

In order to produce so big diameter wrapping tapes , we bought new machinery to produce it and cut it directly by one steps application.
