Studless Link Anchor Chain

Studless Link Anchor Chain

Introduction:

Studless link anchor chain, also called open link anchor chain, are often used for small ship moorings. Compared with stud link anchor chains, the studless link anchor chains have the features of less weight, being suitable for larger shackles without end links.

The production process for anchor chains:

Cutting: cut it into individual chain links. This is typically done using a cutting machine that can cut the steel into precise lengths.

Heating and Forming: After the steel has been cut into individual links, it is heated to a high temperature and then formed into the shape of the chain links. This is typically done using a forging press, which applies pressure to the heated steel to reshape it.

Welding: Once the chain links have been formed, they are welded together to create the anchor chain. This is typically done using a welding machine that can bond the links together with a strong, durable weld.

Testing: Finally, the anchor chain is subjected to a series of tests to ensure that it meets the required standards for strength and durability. These tests may include load testing, tensile strength testing, and bend testing, among others.

Once the anchor chain has passed all of these tests, it is ready to be packaged and shipped to customers.
