Ціна з ПДВ
Heat shrink 2-layer tapes ANTICORTERMO – are widely used in construction of gas -oil pipe lines for troubleproof and high quality coating of line pipes, welded connections, reducers of steel pipes.
Anticorrosive steel pipes coating including (gas, water, oil pipe lines) with heat shrink tape “ANTIKORTERMO”. Different pipes sizes are available. Delivery is possible.
Heat shrink 2-layer tapes ANTICORTERMO – are widely used in construction of gas -oil pipe lines for troubleproof and high quality coating of line pipes, welded connections, reducers of steel pipes. Heat-shrink tapes ensure high quality coating for external insulation in accordance with:
AWWA C215, EN ISO 21809-1, DIN 30670 (UNI 9099), CSA Z 245-20, TS 5139, NF A 49-71.
High adhesive properties of sublayer, material elasticity, high shrinkage degree enales this tape to be used in manual insulation of such extremely curved areas of pipelines as: elbowss, reducers, tees etc. Heat shrink tape is compatible with coating materials based upon extruded PE, PP, PU organosilicon and epoxy enamels and other polymeric materials.
Temperature range under operation from —50…+60оС.
Basic technical specifications:
- Thickness, mm. —1,0…3,0;
- Degree of complete shrinkage, % — 30…50;
- Coating thickness after shrinkage, mm. — 2,0…3,5;
- Thickness of adhesive layer, mm. — 0,7…1,7;
- Adhesion kg/cm.2,
- to primed steel surface, no less than — 3,5;
- to PE, no less than — 3,5.

COATING APPLICATION ON STEEL PIPE WITH HEAT SHRINK TAPE.
TECHNOLOGICAL PROCESS – COATING APPLICATION CONSISTS FROM THE FOLOWING OPERATIONS:
1. Surface preparation.
Work assignment ―mechanical cleaning of external pipes surface from impurities, rust, oxides, scales etc. 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. Modification of pipes surface.
Work assignment ― external steel surface treament with chromate solution for making proper adhesion of coating.
3. Induction heating.
Work assignment ―keeping reqiured range of temperature for further coating application.
4. Primer application (3-layer coating).
The first layer of the primer is applied on heated steal by a method of pneumo-electrostatic evaporation. Minimum primer thickness is 100 mkm.
5. Application of adhesive and protective layers.
- adhesive layer is applied for fixation of steel pipe with polyethylene protective coating.
- primary(protective) layer -ensures protection from corrosion etc.
Adhesive and protective layers are applied by the method of consequantal helix winding of heat shrinkable tape onto preliminary heated steel pipe surface.
6. Water cooling of fresh coated surface.
Work assignment ―enables coating formation, which gives possibility for further pipes transportation.
7. Cleaning of excessive coating at the ends of the pipe.
Work assignment ―cleaning of excessive coating and pipes bevel formation at the ends of the pipes for further pre-commissioning.
