Arc weight = elbow formula with radius multiple M. Tangent weight = 2 × tangent length × per-metre weight. Final weight follows the MTC.
Formula
90°: W = (D−S) · S · K · M · 1.57 · DN / 1000
θ°: W(θ) = W(90°) × θ / 90
+直段: W = 弯头公式 + 2 · L · (D−S)·S·K / 1000
D = OD (mm), S = wall (mm), K = material factor, M = radius multiple (free), DN = nominal diameter (mm), L = tangent length each end (mm).

Radius & Tangent
- R = M × DN — M 自由输入
- 弯头：LR M = 1.5，SR M = 1.0
- 弯管：M = 3 / 4 / 5 / 6 / 8 / 10 / 12 等
- 直段每端 L 自由输入，默认 0（不带）
带直段时重量 = 弯头公式 + 2 × L × 每米重量。
