With industries advancing and developing newer and bigger scale, the requirement for superior material capable of handling the most severe of situations, rises. Talking about flanges one of the most resistant materials that are available in the market is alloy steel. Nevertheless, what makes alloy steel flanges much ahead of the competition? They are robust, long-lasting, and corrosion-resistant, alloy flanges that are broadly used in the chemical, petrochemical, and oil & gas sectors. Continue reading to know more.
It is typically a flat ring or square metal piece with holes attached around its perimeter for bolt or weld connections. Flanges are generally divided into two parts: one fixed to the pipe or equipment, known as the flange seat or flange base, and the other as the connection’s opposite end, the flange plate. The major use of the A105 flange is to allow pipeline systems to be connected and give sealing performance, thereby preventing leakage of fluids or gases.
Carbon, steel, stainless, and alloy flanges are among the flange materials that are utilised.
Carbon Steel: Carbon Steel Flanges have fine mechanical qualities, ease of processing, and affordable cost, carbon steel flanges are arguably the most often used. The materials are ideal for general use in low-temperature industries but may prove slightly limited especially in extreme temperatures or where exposed to corrosive substances.
Stainless Steel: Stainless steel flanges have better corrosion and better mechanical attributes; it is further used in industries where the media is highly sensitive to corrosion attacks like chemical processing industries, food processing industries etc.
Alloy Steel: High temperature and corrosion resistance properties are outstanding in this alloy. Therefore, this alloy steel flange can be applied to high-temperature and super-high pressure, as well as corrosive media pipeline systems.
Cast Iron: Low-temperature, general industrial-use cast iron flanges are broadly popular because of their low prices. Nevertheless, the Inconel 625 Flanges produced is not good at corrosion resistance and other mechanical properties that are unsuitable in certain areas.
Plastic: Its major application is found in the chemical industry or wherever there is transportation of chemical or corrosive medium. The most commonly used plastic ss 316 flanges are the polyethene and polypropylene or PVC flanges, which are highly resistant to corrosion.
Superior Strength: They also possess high strength which at reveiws one of their greatest strengths, apart from having several other properties similar to the ones possessed by carbon steel flanges. Therefore, alloy steel flanges are commonly applied in construction companies, petrochemical industries, and the oil and gas sector because they do not deform under pressure conditions.
Durability: They also can outlast ordinary flanges and this is another advantage of alloy steel flanges. Alloy steels are, therefore, composite systems of steel and any other materials, including chromium, nickel and molybdenum, to mention but a few.
Resistance to Corrosion: Corrosion is a major worldwide problem particularly in the use of industrial products. However, alloy steel flanges are not prone to corrosion; therefore, they can be used where conditions are very aggressive. It is constructed of steel with additional attributes, including chrome, nickel, and molybdenum, to make it more simultaneously highly corrosion-resistant.
A special feature of alloy steel flanges include, making them the most demanded flanges across the globe in industrial applications. Their non-corrosive nature, high strength, durability, adaptability and resistance to fire have made them popular among the engineers and industrial producers of the continent. For those of you who need flanges with higher quality required for service in conditions that are somewhat typical but more severe, then you should consider choosing alloy steel flanges and Hastelloy C276 flanges as your first option.
