A flange that is welded to the end of a pipe is known as a weld neck flange. It is specifically designed and produced to provide a strong and leak-proof connection, making it ideally perfect for high-pressure and high-temperature operations. The weld neck flange has a long neck or short neck that adds new support and strength to the pipe. This design aids in stress reduction at the weld joint, preserving the structural integrity of the flange. These stainless steel weld neck flanges are designed to help companies securely join pipes, valves, and other items without leakaging problems. These include oil and gas companies, chemical plants, and even power plants! These flanges are available in a variety of lengths and widths, as well as special flat surface configurations. The weld neck flanges have narrow openings high on the sides in smaller sizes than larger ones.

A stainless steel weldneck flange is a type of pipe flange designed to be welded onto the neck of a pipe. It provides a smooth, high-strength connection for joining pipes, valves, and other equipment.
Common stainless steel materials include 304, 316, and 321, among others. The choice of stainless steel grade depends on the specific application and the required corrosion resistance.
Stainless steel weldneck flanges are available in a wide range of sizes, typically ranging from 1/2 inch to several feet in diameter. The size you need depends on your specific piping system requirements. All the standard Flange dimensional sizes are Readily available at any Naysha Steel branch in Bangalore.
Yes, stainless steel weldneck flanges can be used with pipes made of other materials, provided the flange material is compatible with the pipe material, and the connection is properly sealed.
In the oil and gas industry, blind Alloy Steel flanges are used in pipelines, storage tanks, and offshore platforms. They are employed for closing off openings during maintenance, repair, or when a branch connection is not required. Petrochemical plants utilize blind Alloy Steel flanges in equipment such as reactors, distillation columns, and storage vessels.
