Weld Neck Flange Manufacturers


Sachiya Steel International is One Of The Leading Manufacturer, Supplier and Exporter of high Quality Weld Neck Flanges. Weld Neck Flanges are usually used in high pressure systems and are suitable for cold or hot temperatures. Also, we can produce as per your drawings and specifications. An ANSI class is a designation kept by a set of specifications or standards, that is meant to convey both the pressure as well as temperature ratings of pipe flanges. In its denotation, the word Class is mentioned after a by dimensionless number. This includes Class 150, 300, 400, Weld Neck Flange Class 600, 900, 1500, and 2500.

Weld Neck Flanges

    Weld Neck Flanges

Flanges are structural systems used to connect pipes, tubes, valves in a piping system. A Weld Neck Flange is made up of a long tapered hub or bore. These flanges possess superior strength and enhanced hardness. They are widely used in high as well as low pressure and temperature applications. The long tapered hub of the Wnrf Flange gives the pipes structural support during rigorous and extreme movement of pipes within the system. Apart from this, flanges also help in low cycle fatigue, which is caused due to extension of the line. The Stainless Steel Weld Neck Flange is highly resistant to all forms of corrosion and oxidation mediums. These flanges possess superior tensile and yield strength. They can be easily machined or elongated. We are the top Weld neck flanges manufacturers in India. Our institution aims to produce the best products, which are available for all at reasonable prices.

A Carbon Steel Weld Neck Flange is designed with a higher concentration of carbon. Due to the presence of excess carbon, these flanges possess enhanced strength and ductility. They also have a low melting point. In the Weld Neck Pipe Flanges, the flange provides a leakproof sealing to the piping system. The inside diameter of these flanges is bored to match the mating of the pipe. This allows for low turbulence and a smooth flow of fluids or gases. A Raised Face Weld Neck Flange has a raised surface above the welding area, which is designed to reduce the surface area on the seal. This helps put pressure on the flange joint to create a strong joint. In the Flat Face Weld Neck Flange, the top surface is machined down to make it completely flat. These flanges are not affected by the bending pressure, which breaks or destroys some flanges when they are bolted or torqued. A Reducing Weld Neck Flange is mostly used in piping systems where there is a requirement to join pipes of different sizes together. These flanges can also be employed to reduce the diameter of the pipe. The Long Weld Neck Flange is a preferred choice in volatile and hostile environments. These flanges are widely used in petroleum, oil, gas, and chemical processing refineries. We are amongst the few Long Weld Neck Flange manufacturers who make use of the best raw materials and latest technology to manufacture all our products.

The Rtj Weld Neck Flange is used in systems where a metal-to-metal seal is required. These high-integrity sealing flanges can withstand high pressures and temperatures above 700-800 degrees. A Weld Neck Orifice Flange is installed in pipelines to check the flow rate of either fluids or gases in a pipeline. All our products can be easily customized in different chemical make-up, shapes, and sizes as per the requirements of our clients. If you have any queries or want to know more about our Welding Neck Flange, contact us for more information.
