Flat welded steel flanges: dimensions and application

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

What are flanges and where are they used?

Flat welded steel flanges, the sizes of which are in the range from 15 to 600 mm, are used in the assembly of the pipeline with the widest profile.

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

Flanges perfectly serve as 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 needed or it should be connected to a flange base, as well as other equipment that has a flange.

Product Parameters

Production requirements include the production of flanges of various sizes, subject to strict parameters.

Flat welded steel flanges, the sizes of which differ depending on their purpose, can be purchased in specialized stores, where an experienced consultant will help you by familiarizing yourself with your needs first.

Manufacturers are not allowed to change the parameters. During installation, it is necessary to check that the diameter of the flange coincides with the same indicator on the pipe. Also, the dimensions of the flanges themselves must match when installing the design. In this case, the integrity and reliability of the building will be ensured.

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

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

Advantages and disadvantages

The advantages of these designs are:

  • reliability and durability;
  • low cost;
  • multifunctionality;
  • ease of use.

The disadvantages of the flanges are the following indicators:

  • need for replacement when the rings wear out;
  • the quality of installation depends on many environmental factors, a clear correspondence of all parameters is necessary.

This type of product is used everywhere: during the installation of central pipelines, domestic support systems, heating pipelines, gas pipelines, fragments of automobiles, various devices.

The technical description is indicated on the packaging and has approximately the following form: Ru from 0.1 to 2.5 MPa (from 1 to 25 kgf / cm 2 ), temperature indicators range from 60 degrees below zero to 300 Β° C with a plus sign.
