Can ISO 6164 Flare Flange be used in shipbuilding pipelines?

Dec 29, 2025

Hey there! As a supplier of ISO 6164 Flare Flanges, I often get asked if these flanges can be used in shipbuilding pipelines. So, I thought I'd take some time to dig into this topic and share my thoughts with you.

First off, let's talk a bit about what ISO 6164 Flare Flanges are. These flanges are designed to provide a reliable connection in hydraulic systems. They're known for their 37° flare angle, which helps in creating a tight seal. The ISO 6164 standard sets the specifications for these flanges, ensuring that they meet certain quality and performance criteria.

Now, when it comes to shipbuilding pipelines, there are a bunch of factors to consider. Ship pipelines have to withstand some pretty harsh conditions. They're exposed to saltwater, which is highly corrosive. There are also vibrations from the ship's engines and movements in the water that can put stress on the pipeline connections.

One of the big advantages of ISO 6164 Flare Flanges is their sealing ability. The 37° flare angle creates a metal - to - metal seal, which is great for preventing leaks. In shipbuilding, leaks can be a huge problem. Not only can they lead to loss of fluid (which could be fuel, hydraulic fluid, or other important substances), but they can also cause corrosion in areas where the fluid leaks. A good seal is essential to keep the ship's systems running smoothly.

Another important aspect is the strength of the flanges. Ship pipelines need to be able to handle high pressures. ISO 6164 Flare Flanges are typically made from high - quality materials like steel or stainless steel. These materials have good strength properties, which means they can withstand the high pressures that are common in ship systems. For example, in the hydraulic systems of a ship, which are used for steering, lifting, and other functions, the flanges need to be able to handle the pressure without failing.

But it's not all sunshine and rainbows. There are some challenges when using ISO 6164 Flare Flanges in shipbuilding pipelines. One issue is corrosion. Even though the flanges are made from materials that are somewhat resistant to corrosion, saltwater is a tough opponent. Over time, the saltwater can start to eat away at the metal, especially if there are any scratches or imperfections on the surface of the flanges. To combat this, proper coating and maintenance are crucial.

Installation is also a key factor. In shipbuilding, pipelines are often installed in tight spaces and complex configurations. Installing ISO 6164 Flare Flanges requires some skill and the right tools. If they're not installed correctly, it can lead to problems like leaks or weak connections.

Let's take a look at some alternatives. There are other types of flanges available in the market, such as the SAE 37° Flare Flange and the SAE 37° Flare Flange O - ring Seal. The SAE 37° Flare Flange is similar to the ISO 6164 Flare Flange in terms of the 37° flare angle, but there are some differences in the dimensions and specifications. The SAE 37° Flare Flange O - ring Seal adds an extra layer of sealing with the O - ring, which can be beneficial in some applications. And then there's the Flared Flange, which also has its own unique features.

In my experience, ISO 6164 Flare Flanges can definitely be used in shipbuilding pipelines, but they need to be used with care. If you take the time to select the right materials, ensure proper installation, and carry out regular maintenance, they can be a reliable choice.

For shipbuilders, it's important to work closely with a flange supplier who understands the specific requirements of shipbuilding. As a supplier, I've worked with many shipbuilding companies to provide them with the right flanges for their projects. We can offer advice on material selection, installation, and maintenance to make sure that the flanges perform well in the harsh ship environment.

If you're in the shipbuilding industry and are considering using ISO 6164 Flare Flanges for your pipelines, I'd love to have a chat with you. We can discuss your specific needs, and I can provide you with more information on how these flanges can work for you. Whether it's about the technical details, pricing, or delivery, I'm here to help. Just reach out, and we can start a conversation about how to make your shipbuilding project a success.

In conclusion, while there are challenges in using ISO 6164 Flare Flanges in shipbuilding pipelines, with the right approach, they can be a valuable component in your ship's pipeline systems. So, don't hesitate to explore the possibilities and see if these flanges are the right fit for your next shipbuilding project.
