Rajdhan Metal takes pride in its production and distribution of their products. One such product is Carbon Steel threaded Forged Fittings. CS grades are the parts of carbon steel forged fittings. The material's exceptional hardness and wear-and-tear resistance are its main uses. We are a top manufacturer of several fittings, including the Carbon Steel Forged Elbow. According to ASME B16.11 requirements, the fittings are robust and come in a variety of sizes. Forged fittings with a size range of 1/8 inches to 4 inches are covered by the standard. There are various kinds, including forged fittings and threaded carbon steel pipe fittings. When welding or bolting procedures are deemed inappropriate, threaded fittings are helpful.
What is Carbon Steel Threaded Fittings?
The CS Forged fittings are stress-resisting and stronger since they are forged from a single piece of raw material. According to how the fittings are designed, there are several sorts, such as socket-welded carbon steel fittings. To keep the pipes in place during and after welding, socket weld fittings are employed with lower pipe sizes. In India, we are the sixth-best maker of forged carbon steel fittings. In conjunction with threaded pipes, the CS threaded fittings are utilized. Following threading, they might potentially be welded. To offer various advantages, several fittings are used. To join two pipes in a way that is pressure-proof, use a carbon steel threaded coupling. In oil and gas applications, such as subsea pipeworks and systems for processing seawater and firewater, these fittings are used. Pressure vessels, valves, and heat exchangers are all made with these fittings. These fittings are utilized in a variety of other industries, such as desulfurization gas equipment, the paper and pulp business, desalination, mining, metallurgy, and the maritime industry, which all require pollution control technology. These fittings are utilized in many chemical industries because they are resistant to acids like sulphuric acids, protecting the machine parts from corrosive chemicals. In a sturdy structure, these fittings are also utilized.

There are different types of threads used in threaded fittings, including:
The specific type of thread used in a fitting will depend on the application and the standards used in that region including thread sizes, tapered and parallel, pitch sizes, and industry standards when it comes to identifying thread types.
