HEAT SHRINK REPAIR SLEEVE

It is then zipped up with a stainless steel channel and is heated to shrink to the size of the pipe. Heat shrink repair sleeve can be used to repair can be made without shutting down the pipeline.

We manufacture heat shrink repair sleeves of multiple sizes, wall thickness, and grades of steel plates which are to ASTM certifications Various grades and types of heat shrink repair sleeves are manufactured by customizing as per the client’s specification.

The REL-80 system provides superior corrosion protection and excellent bonding on pipelines operating up to 80°C. REL-80 has been designed with a unique adhesive technology that remains “open” longer than traditional adhesives. Also, special surface active agents allow bonding to lower surface energy coatings (such as polypropylene). As a result, lower preheat temperatures are required to attain true adhesive wet-out and superior bonding to PE and FBE surfaces is achieved.

A heat-shrink sleeve is a corrosion protective coating for pipelines in the form of a wraparound or tubular sleeve that is field applied.

Heat Shrink Repair Sleeve are the most widely used technology in the world today for field-girth weld corrosion protection because they’re easy to install, provide excellent protection, and are cost-effective.

A heat-shrink sleeve is also known as a heat-shrinkable sleeve or a shrink sleeve. Click here for Half Pipe Sleeve.
Heat shrink means just that—when the heat is applied to the sleeve, it shrinks in size and conforms to the surface it surrounds. A heat shrink repair sleeve starts out with a thick extruded polyolefin sheet (polyethylene or polypropylene) that is formulated to be cross-linkable.

Heat Shrink Repair Sleeve has an adhesive that sticks the sleeve to the material and the factory-applied mainline coating, and also acts as a corrosion protective layer. The backing provides mechanical protection against abrasion and soil stress forces after the pipeline is buried. Heat wrap tape may be used in addition for pipe bends, or as an alternative method for wrapping the whole Pipe.

Heat Shrink tubing is a type of extruded plastic tube that reduces in size when heated to a pre-determined shrink ratio to fit a specific application. A sleeve should be selected in a size larger than required to cover both the wire and components it is to be used with, before being shrunk to fit. Once fitted, the sleeve provides long-lasting durability. Heat shrink repair sleeve is available in various different materials, colours, sizes and shrink ratios to suit the application required. Some are available with an adhesive lining that helps to bond the tubing with the cables and components. Polyolefin is the most common material as it is highly durable and can withstand high temperatures without a restricted shelf life. They are also manufactured from PVC, fluoropolymer, neoprene, and elastomeric materials. The material is often cross-linked to assist with the tubing shrinking back to its original dimensions. The pre-determined shrink ratio, for example, 2:1 or 3:1, is the measurement of how small the sleeve goes in comparison to its expanded size. When the number is higher in the shrink ratio the greater the shrinkage. 

 It allows a precise, secure fit that does not come off easily. Applications Heat shrink tubing is versatile and easy to use therefore it can be applied in an assortment of applications, the most common uses being: Electrical insulation – covering joints and repairs Strain relief – relieving pressure from the cable Wire bundling – in harness building and cable organization Environmental and mechanical protection – preventing damage from abrasion, moisture, dust and chemicals Identification – the wide range of colours the tubing is manufactured in allows it to be used for colour coding and component ID Installation When selecting the right size tubing, you should consider the maximum and minimum diameter of what you are covering. Use this information to check against the recovered diameter (the diameter after shrinking) and expanded diameter (the pre-shrinkage diameter) of the sleeve. You can cut most tubing to a suitable length using standard scissors. The unshrunk tubing can be slid over the area or objects it is to cover. Then with a handheld heat gun or heat shrink oven, the sleeve is shrunk tightly. To prevent uneven shrinkage or overheating, check the recommended heating temperature beforehand.
