How to Choose Threaded Bathroom Fittings?

Threaded fittings made of copper, brass, polypropylene and other materials are used for a wide variety of pipeline systems: cast iron, steel, polypropylene, copper, modern metal-plastic and others. Of course, when choosing a threaded fitting to solve a specific problem, not only its type, dimensions and cross-sections are selected, but also the material suitable for use in the pipeline.

Threaded fittings are prefabricated and disassemblable pipeline elements that can be used multiple times. The use of threaded fittings is relevant in cases where additional installation is expected, service work that requires disassembling the pipeline or other actions that would be difficult if the piping system were non-detachable. On the other hand https://avahome.pk/, compression fittings ( crimping) are used in contrast to threaded ones - where it is necessary to achieve a monolithic connection. Various control and regulation devices are often connected at the installation points of threaded fittings, as well as where it is possible to change the pipeline connection.

The main advantages of threaded fittings are a high level of tightness, which allows for both a detachable connection and minimizing the risk of leakage of liquid or gaseous media, high mechanical strength of the structure ( depending on the material), relative ease of installation ( no need for special technical means), and a long service life.

Materials used for the manufacture of fittings

Threaded fittings are made of various materials that provide certain performance characteristics. For example, copper fittings are highly corrosion-resistant and affordable https://avahome.pk/product-category/floor-waste/, but are of little use in main pipeline systems, brass fittings are expensive, but aesthetically pleasing and have high performance characteristics, and fittings based on polymaterials are lightweight, economical and have excellent resistance to static electricity, one of the main factors of early corrosion. Polypropylene fittings of various types are gradually being used more and more widely on the domestic plumbing market, which is due to their versatility, cost-effectiveness and excellent characteristics.

For threaded fittings that require frequent assembly and disassembly cycles, particularly strong materials are usually used. Stainless steel threaded fittings are quite common in industry , and titanium and other threaded fittings are used in specialized areas. Fittings made of special materials are generally not used in plumbing.

Types of threaded fittings

In plumbing, several types of threaded fittings are used, differing in purpose:

– elbows and bends, the purpose of which is to change the direction of flow;
– tees and manifolds – to create a single branch;
– crosses – to organize branches in two directions;
– couplings – threaded fittings for connecting pipes of the same diameter;
– adapters of various types – to connect pipes of different diameters or types;
– caps and plugs – fittings for closing the ends of pipes in a hermetically sealed manner;
– nipples – as a rule, for connection with a flexible hose in household plumbing, industrial and technical purposes.
