Virgin engineers are the renowned exporter, manufacturer, stockholder and supplier of the high-quality ranges of Stainless steel 321 / 321H manifold valves. The products are very designed according to national and international raw material quality standards. We are offering these fittings in different specifications keeping the different needs and requirements of the buyers. It is thus provided to the buyers at different standards, sizes, working pressure, end connections, pressure rating, connection, flow pattern, and temperature rating. It is made available at customized specifications to the buyers as per the demands they have. It is supplied to the universal and domestic buyers.
The purpose of Stainless steel 321 / 321H manifold valves is to isolate the fluid flow into the system. This is so that the fluid from the manifold upstream doesn’t reach one another part of the system that is downstream. Then it bleeds or vents off the solution that is left at the system on the downstream side of the manifold.
About stainless steel 321/321H alloy -Alloy stainless steel 321 is the austenitic stainless steel that is titanium stabilized with very good general corrosion resistance ability. It is having very good resistance ability against intergranular corrosion after it gets exposed to the temperature at the chromium carbide precipitation ranges of 427 Deg C to 816 Deg C. This alloy is resisting oxidation at 1500 Deg F and is having very good creep rupture and stress rupture properties than other alloys. It is having good low-temperature hardiness. Alloy 321H is high carbon version that was created for improvising the creep resistance and high strength at the temperature more than 537 Deg C. In many cases the carbon content is enabling the twofold certifications.
Fabrication of the manifold valves-
The Stainless steel 321 / 321H manifold valves are made with the proper use of high quality of alloy that is tested and then used. These valves are manufactured under the strict guidance of professional experts that are supervising the workers to fabricate the high quality of valves so it can be used at elevated temperature easily. No doubt the use of advanced technology and contemporary tools/machinery has led the manufacturers to bring out superior quality of the product.
Features- The products possess many good features in it that has led it to be used at many industrial critical applications. It is like high tensile strength, good mechanical strength, dimensional accuracy, fine surface finishes, robustness, long-lastingness, reliability, corrosion resistance, and anti-corrosiveness, etc.
Documents-The documents are offered to the buyers are like heat treatment chart, quality assurance plan, packaging list, guarantee letter, raw material test report, material test report, NABL approved lab test report, etc. Also the TC like mill test certifications in accordance with EN 10204/3.1B, 100% radiography test report, third-party test report, raw material certificate, and buyers report is offered.
Packaging-At the time of shipping of the product, the packaging of Stainless steel manifold valves is done using wooden boxes and carton boxes. This assures safer and harmless shipping of the product to the respective buyers.
