Flanges steel flat welded: dimensions and application

Flat steel flanges are an important connecting element that has become widely used in the installation of the pipeline system.

What are flanges and where are they used?

Flanges steel flat welded, the sizes of which are in the range from 15 to 600 mm, are used when assembling the pipeline with the widest profile.

In themselves, steel fasteners are a flattened ring made of steel, with holes evenly spaced around the circumference, used for fixing with bolts and other fasteners.

Flanges perfectly perform the role of connecting devices for pipes and fittings. Produced and distributed in a set of two units.

As a rule, flat steel welded flanges, the dimensions of which do not exceed 600 mm, are used in circumstances where a detachable pipeline is required or it must be connected to a flanged base, as well as to other equipment having a flange.

Product parameters

Production requirements imply the production of flanges of various sizes, with strict parameters.

Flanges steel flat welded, the sizes of which differ depending on their intended purpose, can be purchased in specialized stores, where an experienced consultant will help you, having previously familiarized with your needs.

The manufacturers are not allowed to change parameters. During installation, check that the diameter of the flange coincides with the same index on the pipe. Also the dimensions of the flanges themselves must coincide when installing the structure. In this case, the integrity and reliability of the building will be ensured.

Flanges steel flat welded, the dimensions and weight of which must be checked, are produced according to the state standard.

1. With a diameter of 15 to 100, the pressure they can withstand will vary from 0.1 to 2 and a half MPa.
2. The weight of the products varies depending on their size. On average, these values range from 250 g to 2.14 kg, given the range of flange presented.

Advantages and disadvantages

The advantages of these structures are:

• Reliability and durability;
• low cost;
• Multifunctionality;
• Easy to use.

The disadvantages of the flanges are the following:

• Need for replacement when the rings wear out;
• The quality of installation depends on many surrounding factors, it is necessary to clearly match all parameters.

This type of product is used everywhere: for the installation of central pipelines, domestic supply systems, heating mains, gas pipelines, car fragments, various devices.

The technical description is indicated on the package and has approximately the following form: Py from 0.1 to 2.5 MPa (from 1 to 25 kgf / cm ² ), the temperature ranges from 60 degrees below zero to 300 ° C with the "plus" mark.
