Shaped articles of iron and steel are widely used in pipe installation.None of these elements is unlikely to succeed to design any sewer or water system.It should be noted that the range fasoniny so broad that it can be made from almost any pipe configuration.
Today there are companies that provide customers with all the necessary fittings.To see the range, enough to visit a few specialty stores, pay attention to the product catalogs.
What materials are suitable for the production of
Any pipe fittings made of steel (also often used iron Ductile Iron).Much depends on what specific tube used - made of the first or the last material.It's simple: if made of steel, the fittings shall be of steel.
Practice shows that iron fasoninu do mainly with the bells, which is why it is believed that this is the most popular type of pipe connections with each other.Although the flange cast iron products also exist.Speaking of the shaped steel parts, they can only be flanged.
What companies offer modern
As a rule, any company with a good reputation has in the arsenal of the production department, where do the fittings.To get fasoninu of cast iron, ductile iron grade material used (high-strength alloy spheroidal graphite).Parameters of production from such raw materials are good enough that the product can be operated for a long time - not less than fifty years.
top fittings coated with different compositions.If the steel product, outside the layer of soil are treated, this time with enamel, which is resistant to corrosion.On the inner side surface is processed - it is forbidden to snip to avoid adverse impacts on water quality, which is necessary to the population.If we consider the cast iron products, here everything is different - they are processed inside the cement-sand composition, with the outer parts - zinc paint or lacquer coating.
It should be noted that the sizes of sockets and flanges fittings fully comply with GOST 5525-88, not only, but also ISO 2531. This product can even be used for installation works that involve pipe from foreign manufacturers.
Classification fittings
We understood that such a molded product is now following talk about the internal classification - it is in every type of product.That is the general name of "tee" combines several types fasoniny, "release" - two "transition" - four.
consider main groups - it all depends on the purpose of connecting parts:
- bends, bends, angles.
- Collectors and tees.
- Transitions.
- plugs.
- flanges.
- connecting cast iron couplings.
- Other elements.
Fasonina: etymology
general, fasteners are so many different names.It is worth noting a few phrases that denote the same products.
- Shaped products for installation (assuming that we are talking about the constituent parts of which are made, for example, water).
- fitting - this concept comes from the English language, can be translated as "mounting, installation."
- Fasonina - the most concise and capacious designation range of products that are in demand during the installation of pipelines.
term "Chugunin" also exists - the word is used to refer to the connecting elements of cast iron, but the concept was not entirely correct.So long been called decorative ornaments for fencing and gates, as well as castings for Russian stoves.Fully cast iron fittings are not, because their surface is quite complicated.
