The invention provides an anti-torsion marking method for a mooring chain, which comprises the following steps of: 1, before marking the mooring chain, straightening out chain rings of the mooring chain, placing the mooring chain on a plane, ensuring that the chain rings needing to be marked are positioned on the same plane, and marking according to the sequence of every chain ring; 2, bright color paint is coated on the single side of each chain ring every other chain ring, the bright color paint serves as an anti-torsion color code and is used for distinguishing whether the chain is twisted or not, the length of the anti-torsion color code is not smaller than 1d, and d is the nominal chain diameter of the chain; and 3, marking the ring number of the chain ring on the anti-torsion color code by using paint with other colors. The torsion condition of the chain ring can be clearly identified, so that the chain ring is straightened out before being installed, the service life is prevented from being influenced by the torsion effect during use, and the service life of the mooring chain is prolonged.
本发明提供了一种系泊链防扭转的标识方法,包括以下步骤:步骤1:在对系泊链进行标识之前,将系泊链的链环理顺,将系泊链放置于平面,确保需要标识的链环处于同一平面,以每隔一个链环的顺序进行标识;步骤2:在链环的单侧每隔一个链环涂上亮色油漆,以此作为防扭转色标,用于辨别链条是否发生扭转,所述防扭转色标的长度不小于1d,其中d为链条的名义链径;步骤3:在所述防扭转色标上用其他颜色的油漆标出链环环号。本发明能清楚地标识链环的扭转情况,从而在安装前将其理顺,避免使用时受到扭转作用而影响寿命,延长系泊链的使用寿命。
