What Are the Common Thread Types in Flanged Pipe Fittings?

Now, as for flanged pipe fittings, it is important to know the various types of threads so that a good fit can be obtained and no leaks will occur. Product description: We can supply a wide range of flanged QiMing KF Fitting with different thread specifications to satisfy your particular requirements. While it does depend on three things: your application, the type of pipe, and the size of pipe, we're here to help you make an informed decision that will lead to a well-installed flanged pipe fitting. Within this post we'll discuss some topics and terms that are helpful when it comes time for you to decide which threading specification you will need. 

Thread Selection for Your Application

The most widely used type of threaded flanged pipe fittings is NPT which is the abbreviation for National Pipe Thread. These threaded pipes can provide an effective seal for pipes transporting certain liquids, chemicals, gases, and fumes. By creating a tighter seal than straight threads, they are ideal for gasoline, natural gas, oil fittings. These threads are commonly found in plumbing applications and are very easy to install. Another common thread type is BSPT, or British Standard Pipe Taper. BSPT threads are also tapered, but the angle is different and they are not interchangeable with NPT threads. You definitely want to use the right type of thread, or you and your new tie rod will be in for some difficulties putting everything together. There are also straight threads, such as BSP (British Standard Pipe) in which the middle of each is a cylinder and the ends should be conical. These threads are generally used when a gasket or sealant is required to stop leaks. 

When choosing the type of threads that you wish to include with your flanged pipe fittings, make sure you take into account what it is that your application needs. There are also other considerations, including pressure and fluid type and temperature that need to be addressed. For instance, if you are using high-pressure systems you can select a type of thread that provides a better seal, as NPT threads does. On the contrary, for corrosive materials you may choose a thread that is less likely to react chemically (like threaded fittings and stainless steel threads). Hint: Understand the Tygon thread categories and match the right grade for your application by analyzing your requirements carefully.

Tips to Choose Thread Types: In North American, you can find: NPT (National Pipe Thread) types in the U.S. market for flanges and threaded fittings; also, there is NPS (Nominal Pipe Size) light pattern available. How to distinguish them? 

It's always a good idea to know the thread type of the equipment you're using in order to ensure a strong tight seal. For determining thread types, the use of a thread gauge is indispensable – but it will only allow you to check whether the torch itself is BSP or not. Just screw the fitting onto your gauge and you're ready to find out what type of thread it is. Another way is to look at the manufacturer’s instructions or writing on the fitting. These markings are often provided to help identify the thread type and size so that you can assure a good fit in your project. 

The Importance of the Right Thread Type for Flanged Pipe Fittings

The correct thread type for flanged pipe fittings is just as important to get a leak-free seal. If they are not the same threaded type or are otherwise incompatible, it can cause leaks, pressure loss and even damage to your building. Furthermore, inappropriate thread type could lead to installation and maintenance issues that take time and money to remedy. Utilizing the appropriate thread type, it is simple to obtain a leak-tight seal and a secure joint that will not loosen or back out in service. 

What Are the Most Popular Types of Threads for Flanged Pipe Fittings? 

NPT, BSPP, and BSPT are the most commonly used thread types of flanged pipe joints. NPT threads are angled and come from North America, while BSPP threads are parallel threads that seem to be more prevalent in Europe. BSPT Thread is also taper while having different pitch angle than NPT thread. Note that it is not possible to use these types of threads interchangeably: always choose the correct one for your purpose. Knowing the similarities and differences between these popular thread types can be helpful and ensure you pick out the correct QiMing CF Fitting for your application to avoid incompatibilities.
