What kind of fittings are used with stainless steel pigtail syphone pipes?

Jun 30, 2026

Hey there! As a supplier of Stainless Steel Pigtail Syphone Pipes, I often get asked about the kinds of fittings used with these pipes. So, I thought I'd share some insights on this topic.

First off, let's understand what a Stainless Steel Pigtail Syphone Pipe is. It's a coiled tube that's used to protect pressure gauges from high - temperature media. The coiling design allows the steam or hot liquid to cool down before it reaches the gauge, preventing damage to the gauge and ensuring accurate readings. You can check out more about Stainless Steel Pigtail Syphone Pipe on our website.

Now, onto the fittings. There are several types of fittings that are commonly used with stainless steel pigtail syphone pipes, and each has its own unique features and uses.

Threaded Fittings

Threaded fittings are one of the most popular choices. They're easy to install and provide a tight seal. You can simply screw the fitting onto the end of the pigtail syphone pipe and connect it to the pressure gauge or the process connection. Threaded fittings come in different sizes and thread types, such as NPT (National Pipe Thread) and BSP (British Standard Pipe). For example, if you're working in a US - based industrial setting, NPT threaded fittings are likely to be the norm. These fittings are made from stainless steel to match the material of the pigtail syphone pipe, ensuring compatibility and corrosion resistance.

Compression Fittings

Compression fittings are another great option. They work by compressing a ferrule onto the pipe when the fitting nut is tightened. This creates a leak - proof seal. Compression fittings are ideal for situations where you need to make quick connections and disconnections. They're also very reliable and can withstand high pressures. You don't need any special tools to install compression fittings, which makes them a convenient choice for on - site installations. Just make sure to use the right size ferrule and fitting for your pigtail syphone pipe.

Welded Fittings

Welded fittings provide the strongest and most permanent connection. When you weld a fitting to the pigtail syphone pipe, you create a seamless joint that can handle extreme pressures and temperatures. Welding is typically done by a professional welder using appropriate welding techniques and equipment. This type of fitting is often used in critical applications where a high - integrity connection is required, such as in chemical processing plants or high - pressure steam systems. However, it's important to note that welding requires more time and expertise compared to other types of fittings.

Flanged Fittings

Flanged fittings are used when you need to connect the pigtail syphone pipe to larger equipment or piping systems. A flange is a flat, circular plate with holes around the edge. You can bolt the flange to another flange on the equipment or piping, creating a secure connection. Flanged fittings are available in different sizes and pressure ratings. They're easy to install and allow for easy maintenance and inspection. If you're working on a large - scale project, flanged fittings can be a practical choice.

Union Fittings

Union fittings are designed for easy disassembly. They consist of three parts: a nut, a female end, and a male end. You can connect the union fitting to the pigtail syphone pipe and then easily disconnect it when needed. This is useful for maintenance or replacement of the pipe or the pressure gauge. Union fittings are also great for situations where you need to make adjustments or modifications to the system.

In addition to these main types of fittings, there are also some specialized fittings that might be used depending on the specific application. For example, if you're dealing with a corrosive environment, you might need to use fittings made from a more corrosion - resistant material. Or, if you need to measure the pressure at multiple points, you might use a multi - port fitting.

Let's also talk about some other related products. Stainless Steel O Type Syphon tube is another type of syphon tube that has an O - shaped design. It offers similar protection to the pigtail syphone pipe but has a different shape. And Carbon Steel Q Or U Shape Syphon is made from carbon steel and has a Q or U - shaped design. These products might be used in different applications depending on the requirements.

When choosing the right fittings for your stainless steel pigtail syphone pipe, there are a few things to consider. First, make sure the fitting is made from a compatible material. Stainless steel fittings are usually the best choice as they match the material of the pipe and offer good corrosion resistance. Second, consider the size and thread type of the fitting. It should match the size and thread of the pipe and the equipment you're connecting it to. Third, think about the pressure and temperature requirements of your application. The fitting should be able to withstand the pressure and temperature conditions in your system.
