I believe everyone understands the truth that any product will have a certain service life, and marine anchor chains cannot be used forever. There is also a scrap period for marine anchor chains. So how can we judge the chain during use? Does it meet the requirements for scrapping?
First of all, the allowable wear value of the chain hoist shall not exceed 10% of the diameter of the circular chain bar material or the thickness of the auxiliary equipment. Secondly, starting from the plane where the main ring is not bent, the main ring should be scrapped if the main ring is twisted more than 10 degrees.
In addition, cracks, bending or twisting, and jamming or stiff blocking between the ring hinges and other phenomena cannot be ruled out. Prohibited to use when. Of course, the permanent elongation of the chain and single ring shall not exceed 5% of the original length. If it exceeds the above conditions, it means that your anchor chain needs to be replaced.
