How to calculate the theoretical weight of hexagonal steel pipe?

This is what many customers who want to customize hexagon steel pipe want to know.

The hexagonal steel pipe is mainly divided into the following three forms:

**
**

Outer circle and inner hexagon steel pipe | Outer hexagon and inner circle hexagon steel pipe | Outer hexagon inner hexagon steel pipe |

**Calculation formula for weight of carbon steel hexagonal steel pipe**

(the following formula is applicable to ordinary carbon steel, such as: 10 × 20 × 35 × 45 × Q345 q195q235, etc.)

Weight of carbon steel outer hexagon inner circle steel = weight of outer hexagon bar – weight of inner circle bar

If the opposite side of the outer hexagon is a (unit m m), the diameter of the inner hole is OD (unit mm), and the length of the steel pipe is l (unit m)

Then the calculation formula is: **(a ^{2}×0.0069-OD^{2}×0.00623)×L ** The unit of weight calculated is kg

Carbon steel outer and inner hexagonal steel pipe = weight of outer round bar – weight of inner hexagonal bar

Let the diameter of outer circle be OD (unit m m) and the opposite side length of inner hexagon be B (unit mm). The length of steel pipe is l (unit m)

Then the calculation formula is: **(OD ^{2}×0.00623-b^{2}×0.0069)×L** The unit of weight calculated is kg

Carbon steel hexagonal steel pipe = weight of hexagonal bar – weight of hexagonal bar

Suppose that the opposite side of the outer hexagon is a (unit m m) and the opposite side of the inner hexagon is B (unit mm). The length of the steel pipe is l (unit m)

Then the calculation formula is: **(a ^{2}-b^{2})×0.0069×L ** The unit of weight calculated is kg

**Calculation formula for weight of alloy steel hexagon steel pipe**

(the following formula is applicable to alloy steel such as 20Cr 40Cr 35CrMo 42CrMo… Etc.)

Weight of alloy steel outer hexagon inner circle steel pipe = weight of outer hexagon bar – weight of inner circle bar

If the opposite side of the outer hexagon is a (unit m m), the diameter of the inner hole is OD (unit mm), and the length of the steel pipe is l (unit m)

Then the calculation formula is: **(a ^{2}×0.0070-OD^{2}×0.00630)×L ** The unit of weight calculated is kg

Alloy steel outer round hexagonal steel pipe = weight of outer round bar – weight of inner hexagonal bar

Let the diameter of outer circle be OD (unit m m) and the opposite side length of inner hexagon be B (unit mm). The length of steel pipe is l (unit m)

Then the calculation formula is: **(OD ^{2}×0.00630-b^{2}×0.0070)×L** The unit of weight calculated is kg

Alloy steel inner and outer hexagon steel pipe = weight of outer hexagon bar – weight of inner hexagon bar

Suppose that the opposite side of the outer hexagon is a (unit m m) and the opposite side of the inner hexagon is B (unit mm). The length of the steel pipe is l (unit m)

Then the calculation formula is: **(a ^{2}-b^{2})×0.0070×L ** The unit of weight calculated is kg

**Calculation formula for weight of stainless steel hexagon pipe**

(the following formula is applicable to stainless steel such as 304 304L 316 316L…)

Weight of alloy steel outer hexagon inner circle steel pipe = weight of outer hexagon bar – weight of inner circle bar

If the opposite side of the outer hexagon is a (unit m m), the diameter of the inner hole is OD (unit mm), and the length of the steel pipe is l (unit m)

Then the calculation formula is: **(a ^{2}×0.0071-OD^{2}×0.0064)×L ** The unit of weight calculated is kg

Alloy steel outer round hexagonal steel pipe = weight of outer round bar – weight of inner hexagonal bar

Let the diameter of outer circle be OD (unit m m) and the opposite side length of inner hexagon be B (unit mm). The length of steel pipe is l (unit m)

Then the calculation formula is: **(OD ^{2}×0.0064-b^{2}×0.0071)×L** The unit of weight calculated is kg

Alloy steel inner and outer hexagon steel pipe = weight of outer hexagon bar – weight of inner hexagon bar

Suppose that the opposite side of the outer hexagon is a (unit m m) and the opposite side of the inner hexagon is B (unit mm). The length of the steel pipe is l (unit m)

Then the calculation formula is: **(a ^{2}-b^{2})×0.0071×L ** The unit of weight calculated is kg

**Attachment:**

Calculation formula of carbon steel hexagonal bar weight: opposite side * opposite side * 0.0069 * length (m) = kg

Calculation formula of carbon steel round bar: diameter * diameter * 0.00623 * length = kg

The above is the calculation formula of the weight of hexagonal steel pipe, and the theoretical weight of hexagonal steel pipe will come out.

We specialize in the production of hexagonal steel pipes. We can customize the hexagonal steel pipes with surface quality requirements according to the drawings. We can provide you with hexagonal steel pipes that are easy to process, do not cost a knife, and save comprehensive costs.

The above is the calculation formula of carbon steel hexagon pipe. If the weight of stainless steel hexagon pipe is required, the conversion coefficient is required.
