The work aims to summarize the several main heat sealing methods for PE thin sheet pipe to further provide the basis for the subsequent study. The advantages and disadvantages of PE thin sheets as hose heat sealing materials were summarized, the heating sealing of PE thin sheet pipe and effects of other factors were analyzed and the status of current advanced filling and sealing mechanism was discussed. PE was mostly used for paste filling, with sealing performance not only related to the material, but also in a great relationship with the sealing conditions. The sealing method was usually heat sealing. The performance of PE thin sheet pipe after heat sealing was related to the three heat sealing elements (heat sealing time, temperature and pressure) and the most important factor was heat sealing temperature. At present, the most popular heat sealing method adopted by enterprises is internal heating. PE thin sheet pipe is more stable when sealed horizontally. The heat sealing technology can realize certain mechanical strength and enough tightness
