Black Tape Pipe Wrap / 100FT Gas Pipe Tape Wrap Offshore Industry Use

Black Tape Pipe Wrap / 100FT Gas Pipe Tape Wrap Offshore Industry Use

Xunda pipe wrap tape offers a series of coating systems designed specifically for in-field applications on new construction pipe or reconditioning of existing pipelines. In-field or in-situ installation is economical and efficient. When cold-applied coating systems are used, a small investment in manpower and application equipment yields a big return in productivity and long-term performance. The reconditioning systems can be applied on existing operating pipelines, which means no loss of revenue or downtime. 

The 0.75 mm pipe inner wrapping tape shall be applied after the Liquid adhesive and before the pipe outer wrapping  by hand or with a wrapping machine

Structure:

The specification of the tape consists of two layers, adhesive layer and film backing

Adhesive: Butyl rubber

Film backing: Special blend of stabilized polyethylene.

Industries that We Serve: 

         Oil, Gas and Water Transmission pipeline market

         Oil and Gas distribution and utility markets

         New pipeline construction markets

         Rehabilitation and Reconditioning market

         Offshore Industry

         Refinery and Petrochemical Plant Industry

         Manufacture of Polyethylene coatings utilizing Butyl based elastomeric adhesives, Polyethylene films and liquid adhesives for corrosion protection of steel pipe.

         Provides corrosion protection with the inherent chemistry of Polyethylene and Butyl Adhesive for resistance to water and oxygen penetration. Oxygen and Water are prevented from reaching the metal substrate, which are necessary and sufficient conditions for corrosion.

         Manufacture of conventional and specialty Polyethylene, Polypropylene and Polymeric Alloys and coating systems for pipe corrosion protection.

         Manufactures PE coatings systems for applications for New Pipe Construction and Rehabilitation and Reconditioning

        Approved to ISO 9001 and to other good manufacturing and technical standards and norms governed within the energy and pipeline industry.

How to wrap the pipe inner tape ?

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, 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 25-50micron(1-2mils)

3.4 After the primer dried, then wrapping the tape(It usually takes 3to 5 minutes.).

3.5 Consumption:

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 application.

4.2 The tape applied temperature must be above 5 degrees,the coating construction temperature shall be more than -5 degrees as better .

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 application.

4.5 Outer tape applied method is the same as above.

5.Cutbacks

Cutbacks shall be a minimum 6inches(150mm) from the ends of each 

pipe.The cutbacks may be tapered or straight edge for the total thickness

of the coating.
