Alloy 20 Flanges suit sulfuric acid service because the alloy resists acid damage across a practical range of concentrations and temperatures. These corrosion-resistant flanges serve demanding chemical processing environments. Sulfuric acid at 20% acts differently from acid at 98%, and heat or impurities shift results further. Corrosion resistance, operating concentration, temperature, pressure and flange compatibility … Read more

System failures occur most frequently at piping joints. Corrosion, harsh chemicals, and constant moisture wear down connection points more quickly in an industrial network. Alloy 20 Flanges are built for exactly this problem. The metal composition resists acid attack and chemical breakdown, which is why these flanges turn up in water treatment plants, chemical processing … Read more

A blind flange placed incorrectly wrong pressure class, incompatible material, mismatched facing fails under exactly the conditions it was installed to withstand. Selecting the right blind flange requires matching material, pressure rating, size, and facing type to the actual operating conditions of the piping system. This guide covers each factor to help engineers and procurement … Read more

A spectacle blind is a safety device used in piping systems to completely isolate or allow flow within a pipeline. It consists of two metal discs—one solid and one with a bore—connected by a small metal web. Because its shape resembles a pair of spectacles, it is commonly known as a spectacle blind. Spectacle blinds … Read more

A lap joint flange is a two-piece flange assembly commonly used in piping systems where frequent dismantling, alignment flexibility, and cost efficiency are required. It consists of a stub end (also called a lap joint stub) and a backing flange. The backing flange rotates freely around the stub end, making alignment with bolt holes easy … Read more

Orifice flanges are specialized pipe flanges designed to work with orifice meters for measuring the flow rate of liquids and gases in pipelines. Unlike standard flanges, orifice flanges are machined with pairs of pressure tappings, eliminating the need for separate pressure taps on the pipe wall. These flanges are engineered to securely hold orifice plates … Read more

Flanges are essential components in piping systems, and among them, blind flanges play a critical role. Designed to seal off the ends of pipe systems, blind flanges are used in a wide range of industries including oil and gas, petrochemical, power generation, water treatment, and shipbuilding. But did you know there are different types of … Read more

In the world of piping and pressure systems, flanges play a vital role in joining pipes, valves, and equipment. One of the most commonly used flange types is the slip on flange. This flange is known for its simplicity, cost-effectiveness, and ease of installation, making it a preferred choice across many industries. At Piyush Steel, … Read more

Orifice flanges are a crucial component in flow measurement systems, primarily used to measure and regulate fluid flow in pipelines across industries. These flanges are designed with a machined hole to accommodate an orifice plate, which helps create a pressure drop, allowing accurate calculation of flow rates. Industries such as oil & gas, chemical processing, … Read more

Tongue and groove flanges are widely used in industries requiring secure, high-pressure, and leak-proof connections. These flanges are designed with matching raised surfaces—one with a protruding tongue and the other with a matching groove—ensuring a tight, self-aligning seal. At Piyush Steel, we manufacture and supply SS 304 tongue and groove flanges, SS 316 flanges, Inconel … Read more
