Just as in mathematics, sets fall into subsets, types of reinforcement can be structured into varieties. Fittings are done by the use of carbon steel flanges.

• variety by purpose and scope

The largest subset is varieties by purpose and scope.

As classification features, operation features can be used - vacuum valves, cryogenic valves, or operating features, for example, shut-off. The basis for separation is also: the installation and the presence of additional options (valves with heating).

But the most significant reason to divide the pipeline valves into varieties is its purpose: control valves, anti-surge valves, pressure reducing valves, drain valves, test and drain valves, etc.

Areas of application for pipeline a420 wpl6 fittings  cannot but impose special requirements on it. The fittings used in the gas industry must be airtight due to the high fire and explosion hazard, which in this case, is the working medium ? gas.

Pipe fittings for the oil and oil refining industries, due to the sufficiently high chemical aggressiveness of oil, must have increased corrosion resistance. An even more aggressive environment, including concentrated acids and alkalis, acts on a860 wphy 60 pipe fittings used in the chemical industry.

• pipeline connection varieties

According carbon steel pipe fittings manufacturers, the reinforcement is divided into flange, wafer, inner flange (i.e., wafer mounted between the pipe flanges). Coupling fittings are equipped with connecting  pipes with internal threads. Welding fittings - pipe fittings for welding to the pipeline. Connecting branch pipes are also at fittings.

• variety in design and body shaping

Based on the position of the nozzles, we can talk about straight fittings (connecting nozzles are coaxial or mutually parallel) or angular reinforcement (the axis of the inlet and outlet nozzles are perpendicular or not parallel to each other). Reinforcement with offset axes of nozzles is also produced.

If the cross-sectional area of the flow part is less than the area of the inlet port opening, ? this is an incomplete passage a860 wphy 52 fitting. If approximately equal to or greater ? full bore fittings.

According to the method of manufacturing hull parts, cast, litho-welded, die - welded, stamp - welded reinforcement is distinguished.

• varieties by type of seals

 Valves in which the stem, spindle, or other movable element is sealed concerning the environment by a stuffing box seal is called a stuffing box.

 Valves for which the packing is not used for sealing are called sealless valves. Bellows and membrane fittings fall into this category.

The alphabets of most languages in the world contain dozens of letters. But this did not stop them from accumulating hundreds of thousands of words. So with a860 wphy 65 pipe fittings ? its incredible variety consists of a relatively small number of classification units, measured in units, sometimes tens. And it appeared not by chance, but because of the need to answer a huge number of questions, to find an algorithm for solving a large number of problems.

Such a wide range of requirements is presented to a234 wpb fittings pipe fittings that often technical solutions by which they can be implemented come into conflict with each other, and the appearance of a large number of various designs is one of the ways to overcome it. And classification is the best way not to get lost in this variety.
