What is stainless steel pipe bend?
Stainless steel is a durable and ductile material that is used for piping and pipe fittings. The material comes in different grades with different compositions. The fittings are of different types such as tees, bends, elbows, and others. The Stainless Steel Bend is used to change the direction of the flow, but it does not change the direction as suddenly as the elbows. The bends are smooth curvatures in the pipeline fittings. The Stainless Steel Mandrel Bend is made by heating and pushing the cut piece of the stainless steel pipe. The process involves pushing the SS Pipe through a mandrel and then heat-treating it.

What is the SS pipe bending process?
The SS Pipe Bend is a machine that is with a rotary draw. Depending on the thickness and diameter of the pipe, the pipe might be preheated for hot forming or bent without heating as cold forming. The pipes are placed on the rotary draw and mandrels are placed inside the pipes and then the pipes are bent to make the Stainless Pipe Bend. The process has to maintain the thickness of the pipe throughout the bend and the diameter has to remain the same throughout the pipe. The mandrels remain inside the pipe to make sure that the internal diameter doesn’t draw lesser than the original diameter. However, differences in the thickness of the outside curvature are possible.

Installation of SS pipe bend
Stainless Steel Pipe Bends Suppliers produce pipe bends in different types. The bend has two ends which can come as beveled, buttweld, or socket weld. Smaller pipe sizes up to 4 inches can come with socket weld which can hold the pipe in place and then be welded. Threaded ends can also be found in the Steel Bend Pipe which can be used with threaded pipe ends. Welding of certain grades of stainless steel fittings might require preheating and post-weld heat treatment to make sure the qualities of the particular grade of steel are retained.

How to find the radius of a stainless steel 90-degree bend?
The bends are usually of 90° angle. They can come with a short radius or a long radius. The Stainless Steel Long Radius Bends are less common. The inside radius is calculated as [(Dw/2/2) + Dp2]/Dp x 2 where the Dp is the depth of penetration and the Dw is half the width of the die. The Stainless Steel Short Radius Bends are the most common. The formulas are to calculate the approximate radius. The real world applications have the radi differed.

How to measure a 45 degree stainless bend thickness?
The thickness of the bends is governed by different standards to make sure that the bends comply with the requirements of different piping applications. The SS Pipe wall thickness can be calculated by the following formula σs=PN.(da-s/20.s)=PN.S where the σ is the hoop stress, the PN is the normal pressure, the da is the external pipe diameter, s is the wall thickness and the S is the pipe serial.

How to calculate the stainless steel exhaust pipe bends radius length?
The pipe bends are used in engine exhausts as well. The pipes are bent to the desired angle and the desired length and used as Stainless Steel Exhaust Pipe Bends for emissions. If you stand the bend against a wall, the distance between the underside of the bend and the point where the wall meets the floor is the main arm’s length. Subtract the diameter of the socket. The final number is the radius of a bend.
