航海英语题库注解图
航海英语题库注解图NylonThis is the strongest of all the man-made fibre ropes. It has good elasticity,stretching up to 30 per cent and returning to its original length. It is usedfor such functions as shock-absorbing when coupled with a mooring wire: the nylon forms a rope tail which takes the heavy shocks as a vessel ranges on her moorings. It is also used in a combination tow line – onesection steel wire and one section nylon rope.Nylon ropes are light to handle, twice as strong as an equivalent sized manilla and give the appearance of a smooth slippery surface. They are impervious to water, have a high melting point, 250?C, and in normal temperature are pliable, being suitable for most forms of rigging. The disadvantages of nylon ropes are that they do not float, and in cold climates they tend to stiffen up and become difficult to handle. They should not be left exposed to strong sunlight or be stowed on hot deck surfaces, as their natural life will be impaired. The significant point with these ropes is that they are used when great stress occurs. Should they part under such stress, there is a tendency for them to act like elastic bands, an extremely dangerous condition to be allowed to develop.The nylon rope will give no audible warning when about to part; however, when under excessive stress, the size of the rope will considerably reduce.They are difficult to render on a set of bitts, and should never be allowed to surge.Any splices in the nylon ropes will tend to draw more easily than in natural fibre when under stress. Nylon is expensive, but its life may be considered to be five times as long as its manilla equivalent.Gooseneck and derrick heel block arrangement.。
