Guaranteed on time delivery
Gayatri tubes manufacture a wide variety of flanges for different types of industrial purposes. Among all the products designed by the company, Hastealloy B2 flanges, remains a popular choice for the industrial applications. The flanges are designed according to the industrial standards and are calibrated in accordance with the proper design criteria. To ensure the delivery of flanges on time, integrated plants are used for construction of the material. The flanges are exported widely across the globe. Flanges are solid structures that are usually used for connecting two or more than two pipes. Generally, in a piping system, there is a demand of transferring the fluids across long distances and to accomplish this, flange is used. With the help of flanges not only the efficiency is maintained, but minimum losses are seen. The flanges provide remarkable strength to the piping system, which would otherwise, is not possible.
The positions at which flanges are used are equipment joints and valves. The reason behind using flanges at such position is to ensure proper maintenance. The method of joining the flanges is done using bolts and nuts. The composition of flanged connection includes set of joints, bolts and flanges. Hastealloy B2 is strengthened with the mixture of nickel and molybdenum alloy and then a solution is formed. The solution thus formed maintains resistance towards the acids like sulfuric acid and phosphoric acids. The presence of molybdenum provides corrosion resistant flange. It is often seen in the flange that there is a formation of carbide precipitate.
However with the presence of nickel, such kind of infirmities is eliminated. Using hastealloy for making of flange helps the flange to sustain high temperature and pressure. The applications of hastealloy flange include chemical process, vacuum furnace and in making of mechanical components. Various kinds of documents are provided by our company to the designed products. The documents are raw material origin certificate, and sound test reports. Tests are also implemented to check the sustainability of the material under adverse conditions. To ensure safe transportation of the material wooden packings are used and the ends of the material are covered with plastics.
