Stainless steel fittings: characteristics and advice for choosing
There are many important components in the pipeline system. Far from the last role is played by stainless steel fittings. With their help, pipes are connected to each other, branches are made, transitions and other manipulations are performed.
Experts note that with the negative impact of the environment, stainless steel fittings are the most successful choice for metal structures.
Key Features
Stainless steel fittings have the same functional characteristics as similar parts from other materials. Polymer products have a lower price, but they can be significantly inferior in quality and reliability.Steel parts have their drawbacks, for example, they may be subject to corrosive processes, and this does not depend on how favorable the operating conditions were. A raid of rust is just a matter of time. Therefore, when working with water and heating systems, preference is given to stainless steel products.
Stainless steel perfectly tolerates the action of moisture and microorganisms. This helps her to serve seamlessly for two or three decades. Such fittings are used in plumbing works and are especially often used both on industrial pipelines and civilian facilities.
Advantages and disadvantages
Like any parts, stainless steel fittings have their advantages and disadvantages. Before buying it is worth reading them in more detail. Among the advantages can be noted characteristics such as strength and durability of products. They are resistant to the occurrence of corrosive processes, as well as calmly related to the effects of most chemicals. The temperature range at which fittings can be operated is quite wide.In addition, they are presented on the market in a wide range, and the installation does not cause much difficulty.
Among the shortcomings, consumers note the high cost of these fittings, as well as the fact that over time they are still destroyed. Of course, black steel fittings will be cheaper, but the service life will be significantly less.
Types and differences
Stainless steel fittings can have a different design and, accordingly, a different purpose. The range offered in the modern market is very wide. For example, a separate type of fittings can be used when connecting a certain type of pipe. However, the most common division of these parts into groups is made by the method of connection.
Depending on this, the following types can be distinguished:
- compression;
- welded;
- crimping;
- threaded.
The most widely used threaded fittings. They are presented in a huge variety of options. It can be both standard elements that are used when working with an end thread, and "American", with two cap nuts in the kit.The principle of operation of the parts is simple: the thread on the pipe and on the fitting are connected and simply wound on each other, and then tightened manually or with the help of additional devices.
Compression parts are similar to threaded ones, only more refined. They have ends in the form of a cone, as well as special seals and crimp nuts. It seals help to get rid of the possibility of depressurization of the connection during further operation.
Welded products got their name due to the fact that they are fastened by welding. They have been used for a long time and are as widely popular as threaded ones. They are distinguished by reliable and hermetic characteristics, provided that the welder has performed his work correctly. The only disadvantage of welded fittings is that they can be installed with special equipment and welding experience. In addition, the pipeline branch after all the manipulations will be already collapsible.
To install crimp fittings, it is necessary to use special tongs. Most often used when working with pipes made of metal.
Species
Fittings, like pipes, serve to perform various tasks in the operation of utility systems. Therefore, they can be divided into several types. Couplings are used when it is necessary to connect straight pipe segments that are made of the same material. With the help of adapters is the transition between the pipes, different in appearance. The bends help to rotate the pipes at an angle of up to 90 degrees, while the corners - up to 180 degrees up, down, or sideways. Crosses and tees are needed in situations where it is necessary to arrange the branching pipes.
With the help of plugs the ends of the pipes overlap. This can be done during the work. Flanges provide the accession of any devices or insert fittings. Stop valves are necessary when it is necessary to stop or, on the contrary, to start the flow into the pipes. A fittings provide a transition from the pipe to the flexible hose. They are irreplaceable in cases when it is required to connect home appliances.
Leading manufacturers
A huge selection of stainless steel fittings and accessories is on the market today. This is undoubtedly an advantage and helps to evaluate various options.Experts advise to purchase products only proven brands, so as not to be disappointed in the quality of the goods. Among the world's leading manufacturers can be noted several companies that have earned a good reputation among consumers and guaranteeing the goods of good quality.
The Spanish company Genebre began its operations in Barcelona in 1981. Initially, it was a small workshop engaged in the production of valves for pipeline systems. Later, the shop expanded, becoming first a factory, and then a huge company that won positive feedback from consumers around the world. The company has been manufacturing stainless fittings for about 40 years.
AWH has been operating in Germany for over 100 years, its products are known and in demand in the world market. In its range of about 40 thousand items, while there is the possibility of manufacturing parts to order. Among the products of stainless steel can be noted valves and fittings.
The history of the French company Eurobinox began its history in 1982and today its products are represented in the plumbing market. Stainless steel products manufactured under this brand,Different types of butterfly valves, welded fittings (polished or matte), check valves and ball valves are included. Food grade fittings are also available.
And finally, another popular company Niob Fluid comes from the Czech Republic. Products made of stainless steel are presented here in a large assortment. The basis of the valve, which can be used in the food and chemical industries.
How to choose and extend service life
To select a fitting, the buyer will need to measure the size of the pipes, as well as know what they are made of. In order not to make mistakes in measurements, experts recommend using a caliper, with its help you can get the most accurate data. Even if you purchased stainless steel fittings from a trusted manufacturer, we must not forget that the highest-quality products need proper handling and care. Therefore, during the operation can not forget about the most important rules.
First of all, you need to pay attention to the transportation was carried out carefully, and the details in its process were not damaged. Especially it concerns the purchase of large quantities of goods.Each product must have a package that prevents the ingress of water. The carriage itself must be carried out in wooden boxes that are securely fixed in the vehicle. At the same time it is necessary to protect the package from moisture and dirt.
As for storage, it is recommended that the fittings be stored in a clean room with moderate humidity. During operation, parts made of stainless steel must be wiped with extremely warm water, as the use of detergents can harm the product. It can be concluded that it is easy to extend the life of these products, it is enough to follow the basic simple rules.
The main advice of experts is that the material of the fittings should be combined with the material of which the pipeline is made.
