PU tube with ★ is a large number of product flow low pressure hose, working pressure at room temperature 8㎏ / cm 2, the maximum working pressure of 10 kg / cm 2., Burst pressure 13㎏ / cm 2. Fluid temperature is too high or corrosive fluid ingredients that may make the hose rupture. Operating ambient temperature is too high or workspace chemical gas, the hose may cause cracking. Warehousing in damp places or long storage period, will make the hose hydrolysis or aging, may lead to breakage. Do not let the hose friction winding, over-stretching, twisting, otherwise damaged hoses will affect the work pressure. High temperature water or oil, please use heat-resistant tube. Pipe length to allow sufficient margin in the use of fast access, cross-section of hose to the formation of vertical mounting.
