The same point and width of heat shrinkable tape and heat shrinkable sleeve

The similarities between heat shrinkable sleeve and heat shrinkable belt are as follows:


(1) Main uses: both heat shrinkable sleeve and heat shrinkable belt are anticorrosive materials used in pipeline anti-corrosion and joint coating construction. Their functions are the same and can be replaced each other.


(2) Raw materials for production: the raw materials used are the same.


(3) Performance: the product performance is almost the same.


(4) Applicable standards: technical standard for polyethylene anticorrosive coating of buried steel pipeline (SY / t0413-2002) and national standard GBT 23257-2009


The width of heat shrinkable belt and heat shrinkable sleeve is set according to the joint coating of steel pipe. Generally, the width of joint coating is 300 mm, but in practice, a little length should be reserved at both ends. In this case, the width is 500m in China. The electric melting set and we practice in the production of the width is not the same, because it also involves a shortened width.

Sales of electric melting sets

The width of heat shrinkable belt and heat shrinkable sleeve is different from that after shortening, and the ratio between the two becomes its longitudinal shortening rate. When we usually produce, the product width of heat shrinkable tape and heat shrinkable sleeve is larger than the determined specification, which is mainly because it is convenient for the heat shrinkable short belt and heat shrinkable sleeve to lap and cover on the pipeline. We should also consider the length of the reserved section at both ends of the steel pipe. The steel pipe should be 3PE complete in the anticorrosion plant




After anti-corrosion, because the pipeline needs to be welded in the future, a certain length will be reserved at both ends of the pipe. Most domestic manufacturers usually set aside about 150 mm at both ends, of course, there are different reserved lengths. Therefore, when considering this factor, it is better to consider the situation of steel pipe in practice. In the construction of joint repair, not only some of the steel pipe reserved section are covered




Heat shrinkable short tape and heat shrinkable sleeve should be made. In order to ensure the anti-corrosion effect, it is also required to make a certain overlap with the whole anti-corrosion coating of steel pipe, at least the overlap should not be less than 50mm.
