Heat shrinkable tapes are widely used in the construction of water-gas-oil pipelines for high quality, trouble proof coatting of weld butts, reducers,  tees, elbows etc. The tape is also applied for hermetization of flanged connections, linear pipeline portion with diameters  from 57mm up to 1420mm. The tape is dublicated material, based upon cross-linked polyethylene and hot-melt adhesive with melting temperature 120°С.

Anticorrosive pipe joints coating as elbows, reducers, tees and others) by means of heat shrinkable tape Anticortermo.

Heat shrinkable tapes are widely used in the construction of water-gas-oil pipelines for high quality, trouble proof coatting of weld butts, reducers,  tees, elbows etc. The tape is also applied for hermetization of flanged connections, linear pipeline portion with diameters  from 57mm up to 1420mm. The tape is dublicated material, based upon cross-linked polyethylene and hot-melt adhesive with melting temperature 120°С.

High adhesive characteristics of adhesive layer, elasticity and heat shrinkable characteristics, enables to apply tapes for manual curved portions of pipeline, elbows, reducers etc.

The width of tape depends upon diameter of the pipe (fitting) and bend radius (from 50mm up to 250mm.

Thickness is about 1,0 — 3,0 mm.

It is necessary to proceed with  mechanical cleaning of external pipes surface from impurities, rust, oxides, scales etc  before tapes coating. This method converts steel surface to some degree of roughness, ensuring tough meshing of coating with steel.  Surface finishing is complied with  values Sa21/2 of Shwedish required standard SIS 0555900 and SP-10 USA required standard SSPC-SP-1.

The pipelines surface is being heated up to 120°С  and helix winded by heat shrinkable tape with overlapping no less than 50%.

The pipe portion with winded tape is heated by propane burner, the tape is shrinked and adhesive layer is melted on steel pipe and overlapping. As a result of it built up solid, monolithic, high quality coating.

The tape is compatible with PE (PP) extruded coating silicone and epoxy enamels, other polymeric materials.

Temperature range of exploitation from —50° С up to +60° С.

Epoxy is certified by standard system of Ukraine -UKRSEPRO.

Basic technical characteristics:

  1. Thickness, mm. — 1,0…3,0;
  2. Thickness of adhesive layer, mm. — 0,7…1,7;
  3. Thickness of coating after shrinking, mm. — 2,0…3,5;
  4. Range of full shrinking, % — 30…50;
  5. Аdhesion, kg/cm.2,

  • — to primered steel surface, no less than  — 3,5;
  • — to polyethylene, no less than— 3,5.

Technological process of outer butt weld coating with heat shrinkable tape «Anticortermo»

 

1.1 It is necessary to proceed with the following pre-coated operations before coating:

  • choose the method of coating application;
  • Set up compliance of coating materials with technical conditions.

All materials should have certificates of quality and comply with technical conditions;

  • to prepare eqipment, coating materials, instructions;
  • to prepare a shelter in case of rain or severe temperature
  • to define volumes for coating operation.

1.2 Technological process of butt weld coating has the following operational stages: 

  • mechanical cleaning of pre coated surface after welding;
  • heating of butt weld portion of pipeline by means of propane burner
  • coating of butt weld portion by means of Anticortermo tape;
  • shrinking of Anticortermo tape;
  • Control of coating quality.

Mechanical cleaning of pre-coated surface.

2.1  It is necessary to proceed with butt weld coating after quality control of butt weld.

2.2  The pre coating surface should be dried out before coating.

2.3  Clean out pre coated surface This method converts steel surface to some degree of roughness, ensuring tough meshing of coating with steel.  Surface finishing is complied with  values Sa21/2 of Shwedish required standard SIS 0555900 and SP-10 USA required standard SSPC-SP-1.

2.4  Clean off grease pre coated surface.

2.5   Proceed with butt weld heating.

2.6  To wind the tape around butt weld surface.

Attention! In case if storage temperature  less than +10 °С, the tape should be placed at  a temperature range 15 °С – 45 °С.  within 48 hours before application. 

2.7   Heat shrinkable tape should be winded without buckles beads etc.

2.8   Overlapping should contain 50% of the total length of the tape.

2.9   The end of winded tape is heated by means of burner and fixed to steel pipes surface.

Shrinking of Anticortermo tape.  

3.1.1  Shrinking of the tape is started from its heating by burner. The burner should be fixed at a distance no less than 7cm from the tape while moving it opposite coating surface of applicated tape.

3.1.2 After coating, check the quality of coated surface.

Storage conditions

The tape in rolls should be storaged at warehouse at temperature range -10°С up to +30°С at a distance no less than 1 mt from heating equipment. Do not store the tape along with acids, liquids etc. Do not put the prodct uner direct UV rays. Do not store ready coated pipes more than 10 days without shelter.
