Choosing the right 317L stainless compression fittings for your plumbing applications can be daunting. But with some research, you can narrow your choices and find the perfect products for your needs. When choosing a fitting, you should consider the design and the installation process. It will help you decide which fitting will work best for your application.
Ferrule Seal
Stainless steel compression fittings are used in a variety of applications. These are typically found in hydraulic and pneumatic systems. These fittings have several different types. There are single-ferrule fittings, double-ferrule fittings, and male and female connectors. Depending on the application, it is essential to understand how to select the correct type of fitting for your needs. The design of the ferrule is a critical factor in the reliability of the compression seal. For basic designs, a one-piece ferrule seal is sufficient. However, using two-piece ferrules is necessary for more demanding applications. The shape must be tapered to keep it aligned with the tubing. A sleeve, or self-flaring ferrule, is used on thinner wall tubing. This type of fitting is often used in conjunction with a nut. The nut will help the sleeve create a leak-tight seal. The nut's torque is usually transferred from the compression nut to the ferrule. This torque can vary greatly, depending on the relevant material and the amount of lubrication applied. If the nut or ferrule is rotated, there is a chance for galling. It can lead to a shift in the ferrule over time or to the nut's threads becoming stripped from the fitting body. The shape of the ferrule is also a significant factor in the reliability of the compression seal. The asymmetrical ferrule is typically preferred for high-tech applications, as it allows for a two-piece design. It also minimizes the number of components in the assembly. Whether you are selecting a single or double ferrule fitting, it is essential to understand how to install the components correctly. The fitting body must be inserted into the end of the tubing. Then, the nut should be tightened about 1 1/4 turns from the finger-tight position.
When looking for the right 317L stainless compression fittings, it is essential to understand the differences between the various types. Steel is the most common and the least expensive, but brass is less attractive than it is. Stainless steel 317 / 317L dual-certified compression fittings are widely used in chemical processing, food processing, and power generation. They have high tensile strength, excellent formability, and good corrosion resistance. They are also able to withstand shocks and vibrations. It is a low-carbon austenitic stainless steel with high chromium content. It has higher tensile strength than other stainless steel. It can resist pitting in phosphoric acid, acetic acid, and hydrochloric acid. In addition, it resists attacks from formic and sulphuric acids. It is also used in applications where annealing after welding is not possible.
Radial Compression
Stainless steel compression fittings are used in a variety of industries. They are instrumental in applications with high-pressure and temperature capabilities. They can be found in water, food, petrochemicals, and beverages. They are also used in nuclear power and fertilizer production. These fittings can withstand extreme temperatures and are easy to assemble. There are two main types of compression fittings. The first type uses a single ferrule. The second type uses more than one ferrule. The diameter of the tubing determines the size of the ferrules. The shape of the ferrule is vital to ensure a reliable seal. The ferrule should be designed to resist galling. When choosing a fitting, make sure it is compatible with the tubing. Softer tubing can cause the ferrule to collapse out of the fitting. This can lead to leaks. Ideally, it would help if you used rigid tubing to prevent this problem. Alternatively, you can add a rear ferrule to keep torque from being transferred from the nut. The number of rotations the nut can perform depends on the thread pitch and lubrication. It may vary significantly between different fitting materials. Some standard material options include 304L and 316L stainless steel, copper, and aluminium. Some manufacturers offer tubing inserts to help with this problem. The inserts are usually metal, but they can also be made from other materials. There are also many challenges associated with using compression-style fittings. Some of these issues include leaks, asymmetry, and rotation. Consider a different type of fitting if your fitting has any of these issues.
Alloy SS 317L can be processed in various ways, including welded, forged, or cold-worked. In addition to the alloy's low carbon content, it can also resist attacks from sulphurous acid, iodide, and chlorides. It is also more resistant to attack at the point of condensation. Alloy SS 317L offers improved oxidation resistance compared to type 316L. The alloy has a low carbon content, which means it can be welded without forming a carbon layer. It can resist attacks from sulphurous and sulphuric acid and from formic and iodide acids.
