Differences between heat shrinkable sleeve and heat shrinkable belt

  We know that heat shrinkable sleeve and heat shrinkable belt are anti-corrosion materials for pipeline anti-corrosion joint coating construction, which play the same role and can replace each other
Since the names are different, there must be differences
Let's understand the differences between the following two: 1
Product shape: the heat shrinkable sleeve is tubular, commonly known as dead sleeve, patching sleeve and heat shrinkable sleeve
The heat shrinkable belt is a sheet, commonly known as looper, patching belt and heat shrinkable belt
In addition to the main sheet, the heat shrinkable belt also has supporting fixed sheets and rubber strips
2
Production process: due to different product shapes, the production and manufacturing processes used are also different
Firstly, in the extrusion stage, the pipe is extruded by the heat shrinkable sleeve and the sheet is extruded by the heat shrinkable belt; Secondly, the heat shrinkable sleeve needs to be expanded into the finished diameter one by one with an expander, and the heat shrinkable belt is synchronously stretched in the extrusion stage; Thirdly, in the gluing stage, semi mechanical and manual gluing are used for heat shrinkable sleeve, small specification is manual gluing, and the heat shrinkable belt is fully mechanical and automatic gluing for the whole sheet; After the rear heat shrinkable sleeve is glued and trimmed, it can be packaged and printed into the warehouse, and the heat shrinkable belt needs to be cut according to the specifications, equipped with fixed pieces and adhesive strips for overall packaging and then into the warehouse
3
Usage: the heat shrinkable sleeve can only be put on before the pipe is welded, and then the heat shrinkable construction can be carried out
When the heat shrinkable belt is used, it is not limited
At the same time, due to the different shapes of the two products, the operation steps and precautions of heat shrinkage construction are also somewhat different
4
Price difference: due to different production processes, small heat shrinkable sleeves are cheaper than heat shrinkable belts, which is attributed to the flexibility of manual operation in the production of heat shrinkable sleeves; The price of heat shrinkable sleeve used for medium pipe diameter is similar to that of heat shrinkable belt, and the heat shrinkable sleeve of large specification is more expensive than heat shrinkable belt, showing the advantage of full mechanized production of heat shrinkable belt
The above four points are the differences between the heat shrinkable sleeve and the heat shrinkable belt
When we choose, we should determine the products according to our specific use environment, and the right products can play their value
