INSULATING PIPING OVER 125 mm IN DIAMETER WITH K-FLEX SHEETS, K 90 BENDS AND K 90 T-FITTINGSINSULATING A STRAIGHT PIPE

Wrap a strip of K-FLEX of the same thickness as that to be used around the pipe to be insulated and measure the exact length required.

Mark out the length required on a K-FLEX sheet.

cut carefully along the line.

To ensure accurate results, use a metal ruler.

Apply an even layer of K-FLEX K 420 gluealong each edge and allow to dry.

Wrap the insulation sheet around the pipe and press the glued edges together starting at the ends, then the center and then working along the rest of the length.

Glue the insulating sheeting to the subsequent sections along the lengthof the pipe.

If the tubing thus created is not correctly lined up, push one against the otherslipping the brush in the gap and twist until they are aligned.

If it is necessary to apply more than one layer of K-FLEX, one sheet can be stuck on top of another. To install the first,refer to page 40.

Contact our TechnicalOffice if you haveto insulate piping

transporting fluidsbelow -40° C.

clean the surface of the first layer of insulation.

Measure the overall diameter with the first sheet in place.

cut out the second sheet to the size required.

Glue the edges of the sheet to be fitted.

Do not stick the two layers together, as the individual sheets may be subject todifferent degrees of expansion or contraction when the plant is operational.

Wrap the insulation sheet around the tubing, ensuring that the seam does notoverlap that of the underlying insulation.

Adjacent sections of insulation should be glued at their respective ends.

When installing the second layer, make sure that the seams do not overlap those underneath (see diagram).This ensures that, when the plant is operational, maximum insulatingproperties are maintained as the materials expand or contract.

INSULATING PIPES WITH K-FLEX ST1500 mm SHEET

L’ISOLANTE K-FLEX proposes K-FLEX ST 1500 mm sheeting, which allows faster application times on straight pipes with large diameters.K-FLEX ST 1500 mm sheeting can be supplied in thicknesses of 6-10-13-16-19-25- 32-40-50-60 mm and in the various versions, standard, or self-adhesive with outer coating in aluminium.The client can also request different sizes, up to a maximum of 1500 mm.

With a 50% wider covering surface than the 1000 mm sheeting, the 1500 mm sheeting has the advantage of requiring fewer segments and, as a result, fasterapplication on long straight sections.

Measure the surface of the piping to be covered.

cut the corresponding section of sheeting.

Apply the sheeting on the pipe, after glueing the joining edges, and bond the two parts, taking care to position them correctly.

If self-adhesive sheeting is used, simply remove the protective film whilepressing the insulating sheeting against the surface to be lagged.

Before starting this operation, the surface of the piping must be thoroughly cleaned, using K-FLEX detergent.
