General Details

Stainless steel pipe bends are available in 90 degree and 45 degree, while 3D and 5D bend pipe fittings are very common used in the industries.

As a reliable supplier of stainless steel pipe fittings, we offer 90 degree bends R=3D 12″ Sch 40S ASTM A312 TP316 ASME B36.19M in attractive price.

We can supply stainless steel butt weld fittings according to ASME, EN, DIN, JIS and GB standards. The major grades are SS 304/304L/304H and 316/316L. We can manufacture the size from 1/2″ to 48″ for elbows and bends, concentric and eccentric reducer, straight and reducing tee, cap and stub end.

Weight Formula of Stainless Steel Pipe Bends

Drawings of Stainless Steel Pipe Bends

The weight formula: 0.0433 x (D-T) x T x R x θ / 100000 + L

D = Outside Diameter
T = Thickness
R = Bend Radius
θ = Bend Angle
L = Weight of Double Sides Straight Length

What is Bend Radius and Angle for Steel Pipe Bending?

Usually R≥3D , such as R= 3D, 4D, 5D, 6D, 7D, 8D, 9D, 10D

Normally 15°, 30°, 45°, 60°, 90°, 135°, 180° or at customer’s option.

What is the Straight Length?

Normally straight length of pipe bends are between 300mm and 1500mm. Also can be customized as per customer’s requirements.
