Quick Overview

Heat-shrinkable molded part for corrosion protection of weld-on blocking tees. BLOT is a heat-shrinkable, two-piece molded part kit pre-shaped to encapsulate blocking tees in gas distribution networks and thus protect from corrosion. The BLOT components are fabricated from a special compound, that fit the contours of the metal tee-pieces. BLOT consists of a "saddle" (a ± 30 mm (1.25") high collar provided with a square flap) and a separate cap provided with a tightly fitting plug cover. The ‘"saddle" is internally coated with a high-viscosity, high-strength mastic to secure the bond to the pre-coated pipe. This also makes the installation easy. The high performance copolymer coating of the cap ensures an excellent bond to the bare steel of the tee-piece. BLOT is installed using regular propane gas torches. The installation is carried out directly on the cleaned and preheated substrate surface. The BLOT "saddle" is fit over the tee-piece and shrunk to firmly adhere onto the service pipe and the tee base. Then the BLOT cap is put onto the blocking tee and, beginning from the plug, shrunk tightly around. During recovery, the adhesive softens and flows to form a tight bond with the substrate. The bond strength builds up during cool down and is fully retained after completion of the job. Product features and benefits include no primer required: no drying time and easy application, Pre-shaped mold system: makes installation easy and provides accurate protection, controlled high wall thickness: provides accurate & reliable protection, small number of sizes for a large number of applications: reduced inventory & logistics costs, specially formulated sealant: ensures a strong bond & reliable protection and provides high peel and shear values after installation, and no special equipment or skills required: makes installation fast and easy and keeps installation costs low. BLOT type products are available as a kit, containing a collar with square flap and a cap with plug cover.
