Virgin engineers are one of the prime manufacturer, suppliers, and exporters of a great variety of Alloy 20 Manifold Valves. We are a global distributor of manifold valves with speedy delivery options. We are stocking the manifold valves in different shapes, specifications, standards, designations, sizes and as per customer requirements. We have been manufacturing manifold valves by the use of the finest grade of raw materials. These are fabricated from trending machines and equipment. Therefore, these valves get desired dimensions as per the set industrial norms. Alloy 20 manifold valves are mostly preferred by the engineers due to its beneficial features some are resistant to corrosion and abrasion. Its dimension accuracy is enhanced by performing industrial finishing process, moreover, it is coated with industrial coats adds prevention from contamination.
Alloy 20 is made up the composition of nickel, chromium, and iron content. This is austenitic grade with elevated corrosion resistance ability even in the chemical reducing zones such as sulfuric acids environments. This grade is stable with niobium element that resists intergranular corrosion attacks. These manifold valves are a potential cost saving option when compared to other standard grades. Moreover, alloy 20 is ideal for processing for severe chemical compound processing such as nitric acid, phosphoric acid, and salt solutions. Alloy 20 made manifold valves are a solid solution for chloride corrosion cracking environments. This manifold can also be exposed in the pitting and crevice corrosive environments. Special consideration should be taken in chloride containing environment because of corrosion rate increases.
Manufacturing of Alloy 20 Manifold Valves: - The manifold valves can be formed either by cold and hot working operation using standard methods. the hot working operation is performed under the controlled temperatures in temperature between 2100- 2250 deg F. this temperature should be maintained up to 1800 deg F. moreover, to attain higher mechanical properties annealing process is performed in temperature up to 1850 deg F. it is quenched with water. If required stress relieving process is performed, it is heated in down temperature below 1000 deg F for a limited time and controlled the temperature. The down temperature properties are attained by addition of heating in at temperature 2100 deg F, maybe this put a negative effect on the stabilization.
Those are Valve seat leakage test, pitting corrosion test, backseat test, closure test, shell leakage test, pneumatic test, intergranular corrosion test, hydrostatic test, and cryogenic testing. Other tests are temperature testing, radiographic test, relief test, transfer valve test, drill stem test, traveling valve test, ultrasonic test, etc.
