OEM Stainless Steel Pipe Fittings Corrosion Resistant 90 Degree Elbow Fittings

Stainless steel pipe 90° elbow fittings are pipe fittings used to change the flow direction of stainless steel pipes, with a bending angle of 90 degrees. It usually has two ports, an inlet and an outlet, and the center lines of the two ports are perpendicular to each other. The shape of the elbow can be long radius (bending radius is about 1.5 times the pipe diameter) or short radius (bending radius is about equal to the pipe diameter). Long radius elbows are more conducive to reducing pressure loss and fluid resistance in fluid transportation.

Common stainless steel materials include 304, 316, etc. 304 stainless steel contains about 18% chromium (Cr) and 8% nickel (Ni), with good corrosion resistance, heat resistance and processing performance, suitable for general corrosive environments, such as indoor water supply and drainage systems, non-strong corrosive medium delivery pipelines in food processing equipment, etc. 316 stainless steel adds molybdenum (Mo) elements (content is about 2-3%) on the basis of 304 stainless steel, making it more corrosion-resistant, especially for media containing chloride ions. It has better resistance and is often used in marine environments, corrosive medium delivery pipelines in chemical production, etc.

Nominal diameter (DN): Common ones are 15 (1/2"), 20 (3/4"), 25 (1"), 32 (1.1/4"), 40 (1.1/2"), 50 (2"), 65 (2.1/2"), 80 (3"), 90 (3.1/2"), etc., in millimeters.

Outer diameter: The outer diameter varies with different nominal diameters. For example, the outer diameter of DN15 is about 21.3 mm, the outer diameter of DN20 is about 26.9 mm, and the outer diameter of DN50 is about 60.3 mm, etc.

Tensile strength: The tensile strength of elbows of different materials and specifications is different. For example, the tensile strength of Stainless Steel Pipe 90° elbow fittings is generally between 520-750MPa. This property ensures that the elbow will not break easily when subjected to fluid pressure and external stress in the pipeline.

The yield strength of Stainless Steel Pipe 90° elbow fittings is about 205-210MPa. The yield strength indicates the stress when the material begins to undergo plastic deformation, which ensures that the elbow can maintain a stable shape under normal working pressure.

Usually has a high elongation, 304 stainless steel elbows can have an elongation of more than 40%, which means that when subjected to a certain external force, the elbow can undergo a certain degree of plastic deformation without breaking, which improves the safety and reliability of the pipeline system.

There are also strict regulations on dimensional tolerances to ensure the connection accuracy of the elbow and the pipeline. Generally speaking, the Stainless Steel Pipe 90° elbow fittings

outer diameter tolerance may be between ±0.5 - 1.0mm, and the wall thickness tolerance is around ±10 - 15%, depending on the pipe size and standard requirements.

If it is a special specification, non-standard customized Stainless Steel Pipe 90° elbow fittings, or an elbow made by special process (such as forging, precision casting, etc.), the price will vary greatly according to the specific requirements and production difficulty. In addition, the purchase quantity will also affect the price. Bulk purchases usually get certain price discounts. Please contact us immediately to place an order.
