Stainless steel is a versatile material, which is made up of steel alloy and chromium. The composition of chromium along with a few other alloys makes stainless pipe fittings resistant to corrosion, oxidation, high temperatures, and sub-zero temperatures. As a result, stainless steel pipes have wide spread applications in textile, chemical, dairy, food processing, power plants, oil and gas processing, and many other related fields. We are the leading producers of Stainless Steel Pipe Fittings manufacturers in India. Our main aim is to produce the best products, which are available to all at reasonable rates.
The ASME B16.9 SS Elbow is a standard elbow, which connects all stainless steel pipes to change their direction of flow. The SS Long Radius Elbow is the most popular elbow to change the direction of flow in pipes. These elbows are produced in many dimensions thereby, ensuring a tight seal to prevent any leakage. These elbows are available in different shapes, dimensions and can be customized to fit any stainless steel pipe. An ASME B16.9 Stainless Steel Stub Endcoexists with a backing flange. A stainless steel stub end has one flared end and one square cut end, which is welded to another pipe of the same size.
The schedule 10 stainless steel pipe fittings are thicker than normal outer diameter pipes. This makes them the perfect choice for custom fabrication and turbo manifolds. The thick walls make it resistant to thermal stress in boilers, condensers, and heat exchangers. Our renowned workers also produce the ASTM A403 Buttweld Fitting by bevelling each end of a valve to match an opening in the pipe. The two ends are then butted to the pipe and welded together.
