Specifications: diameter: 320 to 127 mm thickness: 0.4 to 12.7 mm Length: 6 m above, and, in accordance with customer demand, supply and other specifications of steel pipe

thick wall carbon steel pipe theoretical weight formula


 

A large diameter thick wall pipe size range
       Large diameter thick wall steel pipe is usually more than the outside diameter of 325mm, wall thickness of more than 20mm steel pipe, the largest single weld diameter up to 1220mm, wall thickness up to 80mm. Double weld diameter up to 2020mm.
 
Second, the large diameter thick wall steel pipe uses
       Large diameter thick wall pipe and more used in the construction of a large steel structure, do the main supporting part, such as a bridge piling, seabed piling, piling high-rise buildings. Its material is generally used Q345B, Q345C. The low temperature areas will also be used Q345D, Q345E.
 
Production of large diameter thick wall steel pipe
       Production of large diameter thick wall steel pipe production methods typically include hot-rolled, hot rolled, casting! Large diameter thick wall pipe is more common in the two-sided submerged arc welding production process, the product has been bending commissure within welding outside welding, straightening, flat first class multi-process, achieve the standard requirements of the American Petroleum Institute.

Large diameter thick wall pipe formula
       Large diameter thick wall carbon steel pipe weight formula: [(OD - Wall Thickness) * thickness * 0.02466 = kg / m (weight per meter)
thick wall carbon steel pipe
Seamless Carbon steeel pipe weight: Kg / m = (diameter - thickness) * thickness * 0.02466
 
Steel pipe theoretical weight formula
The calculation method of the steel pipe:
The weight of the steel pipe = 0.25 × π × (OD - squared diameter squared) × L × steel proportion
Where: π = 3.14 L = length of pipe steel the specific gravity fetch 7.8
Therefore,
The mass of the tube = 0.25 × 3.14 × (outside diameter of the square - the inner diameter of the square) × L × 7.8
* If the size of the unit to take m (M), the calculated weight kilograms (Kg)
