SHAIC HS-3401HT Heat Shrinkable Sleeve for High Temperature

Introduction

SHAIC HS-3401HT is designed for welded joint protection for high temperature up to 80 (176) of plastic coated

steel pipelines such as PVC, polypropylene, polyethylene, or fusion bonded epoxy. It has a thick irradiated crosslinked polyethylene backing coated with heat sensitive adhesive and two parts of liquid epoxy primer. Apply epoxy primer to the pipe surface and then adhesive flows and forms a reliable corrosion protection seal onto epoxy and adjacent coating surface. SHAIC HS-3401HT is complied with EN 12068-C HT 80 UV.

Long-Term Corrosion Protection

After heating, formed corrosion protection seal and strong backing provides outstanding waterproofing effect and high

chemical resistance.

SHAIC HS-3401HT 3-layer corrosion protection system resists impact, abrasion and ultraviolet light as well as

excellent resistance against cathodic disbondment, dielectric breakdown.

Bulk Rolls

SHAIC HS-3401HT is supplied in bulk rolls, which is cut in the field for any size of pipe.

No need to drive to warehouse and just cut customized length in the field in time that reduces inventories and

saves the cost & time

Installation

SHAIC HS-3401HT is used for 3 layer coating system upon customer’s specific project requirement.

Please contact with our representative for appropriate installation. Apply epoxy primer over foreign matter-free and

Pre-heated surface. Wrap the sleeve around the pipes.

Fix the center of pre-heated patch closure on the overlapped end and start to heat sleeve in the center.

Move the torch around pipe circumferentially to heat the left and the right of sleeve. Finish off by heating vertically over the entire sleeve to ensure a uniform adhesion and by using a roller or gloved hands to remove wrinkle and air.

SHAIC EPOXY PRIMER is designed for 3 layer coating system for superior corrosion protection of field joints of

steel pipelines. Epoxy primer corrosion protection resists impact, abrasion as well as cathodic disbondment,

dielectric breakdown.

Application Procedure

1. Prepare the pipe surface as recommended in the product application.

2. Pour cure into base as 3 parts base to 1 part of cure.

Stir the mixture for a minimum of 30 seconds to ensure homogeneous mixture.

3. Apply mixed epoxy primer as indicated in the product application.

4. Epoxy Primer covers 20 sq.m/gallon (215 sq. /gallon) or 5.3 sq.m/liter (57 Esq. /liter).

This coverage is based on 4 to 6 mils of thickness & assuming 20% waste.
