Stainless Steel Pipe Fittings
Stainless Steel Elbow
Stainless Steel, Duplex SS, Nickel-based Alloy, Titanium etc.
What Is Stainless Steel Elbow
In stainless steel piping system, stainless steel elbow is used to change the flow direction in the pipe. According to its angle, the most commonly-used ones are 45°, 90° and 180°. And in some engineering projects, 60° elbow or other unconventional angle elbow are also required. Except for stainless steel, the materials of elbow we do also include alloy steel, nickel-based alloy, titanium alloy etc.

Techniques of Elbow
Generally, the main system of industrial pipelines is mainly connected through butt welding. To improve the welding quality, the end will be beveled to form an angle and edge based on standard requirements. ASME B16.25 Standard has specified for the beveled angle, and the allowable deviation and detection method. For stainless steel elbow, its surface quality and mechanical properties are basically the same as pipes. Due to the performance requirements and ease of welding, the materials of stainless-steel fittings are usually required to be of the same as the connected pipes.
Packing of Elbow
For those elbows or pipe fittings without special packing requirement, if their size is 2” or below, we usually seal with plastic and then put them into plywood case. However, for the elbows of large size, we normally pack with pallets and give a protection for the beveled end. As for the pallets number, it will depend on the actual size of elbow. Undoubtedly, we will also mark the details in the packing, not limited to the size, materials, trademark, etc. We can also do color labeling for products according to customer requirements, so that they can rapidly distinguish the materials when the products arrive.
