Cast steel chain, chain flash welding, forging national standard chain standard chain What is the market price chain, manganese steel anchor chain fitting end shackles, chains complete specifications, non-standard chain to map processing, chain link way today to tell you is that when I customized chain issues to consider: chain link There are many ways to go so sets of chain rigging shackle so the whole chain equipment to keep our sales What better way to say who is the link, there are drawings based on the drawings is best to link the processing. Outfitting a coefficient number calculated according to a formula of, and the projected lateral area of ??the ship, the wind speed, flow velocity, interpolation table taking anchors and cables. The formula ships and riverboats are not the same. Engineering boat anchors and cables selected in accordance with the actual demand, even if subject to pulling its chain to take the anchor and chain length. Also when the chain Inquiry Inquiry Contact salesman said to pay attention to the following points: 1. What method of manufacturing chain Classification: steel anchor chain, flash welding anchor chain, forged chain. 2. The chain link structure: stud chain and studless chain. 3. The chain uses: marine anchor chain and offshore mooring chains. 4. The chain of steel grade: Marine chain points AM1, AM2, AM3 three mooring chain points R3, R3S, R4, R4S, R5. In addition the company also produces ring chain series: high-strength chain, mining chain, G80 lifting chain, tub chain, green, stainless steel chain, chain fence, slag chain, lifting chain, marine chain, chain pier, fishing chain, tied chains, tied chain, boat cover chain, hatch chain, hatch chain dedicated connection ring, buoy anchor chains, stud, studless anchor chain, hatch chain, studless chain, stud anchor , tying chain, boat cover chain Normally, chain length of 4-7 times the water depth is appropriate, large waves weather or poor sediment anchorage should be appropriately extended. According to the following formula: 4D + 145M di-chain length. D is depth. Ship chain segments on the manufacture and use of the mark length units also use "section" are generally defined chain length of 27.5 m is 1; Chinese ships to use the logo of a 2O meters. The total length of the civilian chain are integral multiples of 27.5m. Therefore, when the value is even, about the length of the chain should be equal; and when the value is odd, than the left and right chains are to be a long chain ----- See Ship Design Manual
