UNS No6022 Hastelloy C22 Lapped Joint Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS No6022 Hastelloy C22 Lapped Joint Flanges in Mumbai.
Hastelloy C-22 (UNS N06022) is a high-performance nickel-chromium-molybdenum-tungsten alloy engineered for superior resistance to both oxidizing and reducing environments, especially where chloride-induced pitting, crevice corrosion, and stress corrosion cracking are concerns. Its high chromium content compared to many nickel alloys gives it enhanced protection in oxidizing acidic media, while the molybdenum and tungsten additions lend strength against reducing media. Because of this balanced corrosion performance, C-22 is frequently selected in chemical processing, pollution control, flue gas systems, and chlorine/pickling environments.
As a manufacturer, Synergy Engineering Solution would typically source high-quality alloy billets or forgings of UNS N06022, then carry out precision forging, heat treatment, machining, faced finishing, and non-destructive examination to produce lapped joint flanges that meet strict dimensional and metallurgical specifications. In its role as a stockist, Synergy would maintain an inventory of commonly used sizes, pressure classes, and facing types (RF, FF, RTJ) to support urgent or emergency demands. As an exporter, Synergy would combine these manufacturing and stocking capabilities with logistics, export documentation (such as certificates of origin, material test reports, inspection certificates), and global shipping networks to serve clients in Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, Africa, and other markets.
Lapped joint flanges in C-22 offer additional installation flexibility: the loose backing flange (lap type) allows rotation and repositioning without stressing the pipe, which is useful in complex piping geometries or lined systems. For customers who demand tight alignment, periodic maintenance or reorientation, C-22 lapped joint flanges provide both the corrosion resistance of the base alloy and mechanical convenience of a lap joint. In highly corrosive or aggressive process environments, the use of C-22 ensures that the flange does not become the weak link, supporting longer service life and reduced downtime.
Synergy’s global export capability means that clients across the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait) can receive reliable supply locally, often with shorter lead times thanks to regional stock or logistic hubs. In European markets (Spain, Germany) and North America (USA, Canada), Synergy can compete as a specialist alloy supplier by offering full certification, third-party inspection, and custom packaging for import compliance. In Africa and beyond, Synergy positions itself as a dependable source of specialty nickel alloy flanges — particularly where local suppliers may not stock advanced superalloys like C-22.

In practice, Synergy’s target industries for C-22 lapped joint flanges would include chlorination plants, chemical and petrochemical process units, waste treatment and flue gas scrubbing systems, offshore and marine applications, and specialty process skids dealing with mixed acid, halide, or oxidizing/reducing chemistries. The company would support clients by providing technical advice on flange selection, pressure rating, compatibility with gasket materials, and quality documentation. With this approach, Synergy can build reputational strength as both a technical partner and a reliable global supplier of advanced corrosion-resistant flanges made of UNS N06022 / Hastelloy C-22.
With a robust global logistics network, Synergy Engineering Solutions is capable of delivering these high-performance flanges efficiently to any region worldwide. Their dedication to quality, timely delivery, and customer satisfaction positions them as a leading supplier of Inconel 800 Lapped Joint Flanges for industries that demand superior corrosion resistance, high temperature strength, and operational reliability.
