Today Duplex Steel S31803 / S32205 Manifold valves are manufactured and offered by numbers of industries and Virgin Engineers are one among those. We are a manufacturer making it by using the very good quality of raw substances. The use of better quality of alloy makes the product greatly stronger and other industrialists can buy and use those at the high-temperature atmosphere. Our company is dealing globally with the wider ranges of product. The product variety is differentiated on the basis of different types, sizes, standards, dimensions, end connections, pressure rating, etc. our company is also offering the same at custom-built specifications same as per the needs.
2205 is one of the mostly used duplex steel grades. Today it has found many applications because of high tensile strength and very good corrosion resistant feature. The composition of standards duplex S31803 is refined by the steel suppliers and that has resulted in the restricted composition as UNS S32205 was endorsed. Duplex S32205 provides very good corrosion resistance ability but for Duplex S31803 that is currently developed is also complying with S32205. But S32205 is not right for use at the high temperature above 300 Deg C because it is suffering from the precipitation of brittle small constituents and not below -50 Deg C due to ductile to brittle transitions.
The production factor of the Duplex Steel S31803 / S32205 Manifold valves, it is executed by the utilization of very good quality of alloy. The raw materials used are 100% pure and is well tested so that no ineffective quality of manifold valves is produced. The designing and fabrication of the same are done by using refined technology and modern tools under the tight supervision of a professional team. The entire ranges of valves are developed according to the national and international product quality standards and set production norms.
The material testing is playing an important role in the manufacturing unit as it helps us to check the quality of the product. The testing done in the testing facility is like positive material identification test, hardness test, intergranular corrosion test, flattening test, flaring test, chemical test, mechanical test, non-destructive test, and destructive tests.
The test certifications to the buyers are provided is including manufacturer test certifications as per EN 10204/3.1B, third-party test report, raw material certificate, and buyers report. The documents offered to the buyers are heat treatment chart, raw material test report, guarantee letter, material traceability report, packaging list, quality assurance plan, NABL approved lab report, chemical/mechanical reports, etc.
In order to supply every single piece of produced ranges of Duplex Steel S31803 / S32205 Manifold valves without getting damages, it is packed carefully. As the product during the time of shipment needs to pass through numbers of channels to reach its endpoint, the chances of getting harm become a little bit high. So it is packed into wooden cases and carton boxes for harmless shipping.
