A vertical anchor windlass is a stainless steel device that rotates vertically with the deck, while the electric motor and the gear box are sitting in the chain locker, it allows a reduced volume above deck.
When installing vertical windlass, the chain locker is required to be situated away from the windlass. Chain pipe is one of the key component of vertical windlass that provides the best possible solution. The chain pipe covers the entry to the locker reducing the water intake. Square and round rollers are available for stud and short link chain respectively. The curvature of the chain pipe also prevents water ingress to anchor locker, preventing the shipping of water. It also acts to guard the moving chain and provides an elegant look in keeping with the windlass.
Maybe you will ask how the chain pipe is made? Before deciding a proper manufacturing process for the chain pipe, material should be first confirmed. Considering it works in marine environment, the material of the chain pipe should be corrosion resistant. According to the structure, the chain pipes are normally investment cast of marine grade 316 stainless steel with mirror polished finish. Due to the good corrosion resistance of 316 stainless steel, cast chain pipes are capable to withstand the demanding marine environment. When combined with a windlass, the chain pipe ensures the smooth movement of the chain from and to the chain locker of the boat.
Stainless Steel Casting of Chain Pipe in CFS Foundry
Stainless steel casting in CFS Foundry is an extremely versatile, cost effective investment casting manufacturing method for creating complex stainless steel components with fine detail and good dimensional accuracy. It can eliminates the need for costly machining operations. Additionally, as several parts can be made as one casting, the time and cost involved for subsequent assembly is removed. This provides numerous advantages and flexibility for engineers and designers and can be a great alternative to other manufacturing processes. Complex shapes can be formed and minimal surface finishing is thus required for the parts and various metals and alloys can be used within the process.
Compared to stainless steel sand casting, stainless steel investment casting offers tighter dimensional tolerances, better surface finishes, produces near-net shape parts which therefore require less machining and other processing, and allows for the casting of complex-geometry parts and intricate details such as lettering and logos.
CFS Foundry is the professional on stainless steel investment casting and secondary operations such as post machining, various surface finishes, etc. We can supply OEM casting and mirror polishing service for various types of stainless steel marine hardwares including vertical windlass chain pipes. Investment Casting for stainless steel chain pipe can convert molten stainless steel in a single operation to precision vertical windlass chain pipe with minimum wastage of material
Main manufacturing process of cast stainless steel chain pipe include: Creating wax patterns with the same shape of chain pipes, then repeatedly dipped into liquid ceramic. The ceramic hardens and then the wax is melted out leaving you with a ceramic mold. Molten 316 stainless steel is then poured into the ceramic cavity where the wax once was. Once the material solidifies, the ceramic mold is broken and removed leaving the chain pipe castings. The mold used to create the wax pattern can be used many times however the ceramic mold is broken and discarded with each part. Our stainless steel foundry has introduced some automated equipments to ensure a shorter lead time and larger production capability.
CFS Foundry has more than 35 years’ experience in stainless steel investment casting. Request a quote today on stainless steel casting for your vertical windlass chain pipe or any other part? Just pls contact us right now!
