Set the weight of the shaped tube

relationship of internal and external components of building materials

details on how to carefully calculate the load on the pipeline replacement in the building, see below in the article.You do not need special education - enough to care.

As already mentioned, the density profile of the pipeline is equal to 7.8, may vary the amount of metal used, which is well established in state standards.If the consumption of metal in the manufacture of the material provides less than planned, like building material is better not to use for indoor installation.

Yet, so as not to make a mistake in the purchase, the buyer needs to navigate freely, know the formula and do weight calculations and the length of the profile system.

Formula weight profile systems

To calculate the weight, you need to use multiplication formula.First, multiply the volume of the material on its density (constant value of 7.8 cubic meters).So we expect:

MP= S * 2 * (A + B) * p.

Remembering the lessons of physics:

• S - wall thickness,
• The Au - prodilya length,
• p - density (7.8 cubic meters).

Determination of pipe

To calculate the volume, there are several ways:

1. consider the difference between the amount of the metal pipe of the same size and volume of the internal cavity.
2. calculates the sheet spent on production
3. summarize the volume on each side of the finished product.

most widespread method first.To do this, take a profile pipe segment, define its length, measure the external dimensions of the height, width, and internal parameters of the same quantities.Then multiply the external width, height.The result would be equal to the whole volume of the metal tube.

necessary including multiply inside width and height.This is the volume of internal space.The difference between the amount of solid metal and internal space is the volume of metal in the profile tube.A similar formula for calculating the volume of a very clear and effective.

Well, in the end we will open you a terrible secret: there is a simple formula to estimate the weight of the shaped tube, equal to 1m.Although, even here you can do without formulas - you just need to read the table.

Other methods of calculating

For other methods of calculating the weight and volume, you can always turn to a special document "State Standard 8639-82".A complete list of weight values ​​of 1 meter length of pipe calculated each kind of specialized assortment of building materials.The values ​​refer to the table.

The mass meter segment shaped tube should be multiplied by the length of the interval meter products.
