How do I know how much weight to 1 m pipe steel and metal

The easiest way to determine the weight of the steel pipe

purely rhetorical question for people to equip their lives for the long haul.Calculation of any pipe system, suspended from a structural load-bearing surface of a residential building in the parameters weight tubulars required.Profiled steel tubes used in the mounting frame or the production of metal trusses of profile pipes for the roof, too, should ideally be based on kinetic and dynamic load.

Imagine a simple situation: you decide to spend a holiday of steel pipe (water supply, heating, sewage and anything up to pivoprovoda) whose weight is only important for Intra-wired networks.If the estimated performance network diameters are known to you, and design requirements for installation products listed in the technical regulations, the elementary appeal to the calculation tables.

But before you begin to look for in a network similar to the tabulated values ​​of shaped steel products, getting tangled in the product mix, internal and external diameters and other technical nonsense, let me give you some advice.

• locate the first available network site, which has source code with GOST 8732-82 (round), 8645-68 (rectangular products) and you will find the weight of 1 meter of any steel pipe from the assortment of rolled pipe (seamless orwelded, produced by cold deformation or hot, in other words, any), which is produced in our country;
• there on the Internet, you can find a calculator, not only per meter pipe of any type, but its rates in arbitrary units;
• could not find your option back to the most notorious calculation tables weight of metal pipes and other steel products.

To use the calculator for calculating the weight of the steel pipe

usually steel grade used for the production of rolled metal products of any shape (angles, channels, brands, round and shaped tubes) is not included in the calculations.The density of the industrial mix of steel suspended shall be equal to 7800 kg / m3, it remains only to determine the three-dimensional characteristics of a particular product.

1. To calculate the weight of 1 meter of round steel pipe is required to measure and enter only two values: the outer diameter (which can be found in the accompanying documents to the party or to identify yourself with calipers) and wall thickness (the same way).
2. Square and rectangular cross-section profile: ask side (tube side) and the same thickness of the notorious.Additional parameters, such as rounding a corner, manufacturing technology (seamless, cold-formed, etc.) you do not necessarily know.

How to independently calculate the weight of 1 meter steel pipe

For people who fundamentally do not trust Internet snag, we can offer the best way to assess weight wait any hollow tubes.Normally, this indicator is required in determining the length of the pipe rolled, which so happened, it is not sold in the molded dimension and tons.

Assume for routing your battery cottage water system required by the circuit design 300 meters galvanized pipe sections with an external diameter 20 mm wall 2, i.e.with an installation size 16. From table data we find that the weight of 1 meter of a metal pipe is 1,075 kg, then a ton of the pipe rolled you buy 930.23 m of finished products.

you want to count yourself?Elementary: mentally roll out meter section of the round tube into a flat sheet and count the amount of structural material.For those who forgot school course of geometry and physics, remind:

• the length is 1 meter;
• width equal to the circumference of the pipe P: For this round 3,14159hD (outer diameter);for profile 2 (a + b), in other words the outer rims of the rectangle;
• height S equal to the thickness of the shell pipe rolling;
• density of the material we know: 7800 kg / m3.

can only multiply these values: X = RhSx7800 for the case discussed above to receive 3, 14159h0,02h0,002h7800 = 0.98 kg.

result is usually obtained understated, but the coveted weight of 1 meter steel pipe, its price and the price of all future construction (Pipeline construction or metal farm) become visible and understandable.
