Hastelloy blind flanges are made of nickel-chromium alloy with added molybdenum, and are excellent Hastelloy blind flanges. They have higher mechanical properties through the addition of manganese and silicon. Flanges are available in various Hastelloy grades depending on the required characteristics. It is heat-strengthened to operate in a higher temperature range. There are many corrosive environments around these flanges, but the corrosion mitigation effect is not good. The overall performance improves the durability and repair time of these flanges, reducing maintenance and production costs.

Why Choose Hastelloy Blind Flanges?
Hastelloy Blind Flanges are designed to block pipeline flow or seal unused pipe ends. Use these flanges for temporary closures for inspection and cleaning. Critical applications such as oil and gas transportation use these flanges to redirect flow by sealing the ends. Hastelloy makes these flanges stronger and able to withstand internal stresses due to pipeline pressure. In addition, tensile and fatigue strengths extend flange life and prevent cracking. Excellent resistance prevents decomposition that can be triggered by many corrosive environments such as acids. These flanges excel in external oxidation, eliminating the risk of corrosion, pitting, and cracks.
