Rajdhan Metal is a leading manufacturer, supplier, and exporter of Carbon Steel A105 Forged Coupling in India. We manufacture Carbon Steel A105 Forged Coupling per client specifications to fully meet their needs. Rajdhan Metal offers a high-quality ASME Carbon Steel A105 Forged Coupling that is specifically developed for a variety of pipe applications such as HVAC systems, MEP industries, fire fighting industries, building and construction industries, and many more.
Our goods are produced using high-quality raw materials and are guaranteed to fulfil industry durability standards. Our Forged Couplings are a sort of fitting that connects two pipes. We provide forged couplings, which are used in some applications due to their improved strength and lifespan. To ensure long-term endurance and quality, all of our pipe fittings and coupling items are constructed using high-quality steel and cutting-edge technology. Furthermore, the size and thickness of these fittings may be changed to match the specific demands of our valued clients.
What is a Coupling?
Couplings Made of Forged Carbon Steel grade A105 are used to make A105 CL3000, which is carbon steel that is commonly used for pipeline components, flanges, and fittings. This carbon steel grade is suited for use in pressure systems and at temperatures exceeding ambient. It has good machining properties, as does any low-alloyed steel. Each coupling has the size, grade, and pressure ratings. It might also be due to the kind of thread (execution and marking are under applicable requirements). Our provided A105 steel connection ensures the system's safety and lifespan.
