Elbows are commonly used fittings in our pipeline industry, and the calculation of elbow weight and area is used in construction and quotation. For beginners who have a lot of data and related dimensions, they are not very clear. Based on the principle of simple understanding and more than ten years of experience in elbow manufacturing, summarize the calculation formula and related dimensions of any elbow. I hope it will be a promotion for friends who love the pipeline industry and improve their pipe fitting skills. Elbows can be divided into stainless steel elbows in stainless steel pipe fittings, stainless steel wire mouth elbows, elbows in stainless steel high-pressure pipe fittings, as well as carbon steel elbows in carbon steel pipe fittings, and carbon steel high-pressure pipe fittings

Calculation of Theoretical Weight of Elbows

1 Circular elbow: (outer diameter wall thickness) * wall thickness * coefficient * 1.57 nominal diameter * multiple

Coefficient: carbon steel: 0.02466 stainless steel: 0.02491 alloy: 0.02483

Explanation: 90 degree elbow outer diameter wall thickness * wall thickness * coefficient (0.02466 for carbon steel) * 1.57*

*Nominal diameter * multiple/1000=theoretical weight of 90 degree elbow.
