UNS N10276 Hastelloy C276 Lapped Joint Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N10276 Hastelloy C276 Lapped Joint Flanges in Mumbai.
Hastelloy C-276 (UNS N10276) lapped joint flanges are fabricated from a nickel–molybdenum–chromium alloy engineered for exceptional resistance to both reducing and oxidizing environments and to localized forms of attack such as pitting and crevice corrosion. The alloy’s balanced chemistry (high nickel with substantial molybdenum and chromium, low carbon and controlled impurity levels) gives C-276 outstanding corrosion resistance in chloride-bearing media, wet chlorine, oxidizing acids and mixed acid environments — making it a standard choice for chemical processing, pollution control, and offshore/energy applications where aggressive chemistries are present.
Synergy Engineering Solution manufactures, stocks, and exports Hastelloy C-276 lapped joint flanges using controlled forging and precision machining workflows to ensure full dimensional and metallurgical integrity. Production typically involves forging to appropriate flange blanks, finish-machining of the face and bore to standard flange dimensions, and careful inspection and testing (visual, dimensional, and where required, NDT). Synergy emphasizes traceability and can supply material test reports (MTRs), chemical and mechanical test certificates, and third-party inspection when requested by project or regulatory requirements.
In service, C-276 lapped joint flanges provide both corrosion performance and ease of installation: the lapped joint (loose) flange design allows for easier alignment in piping systems and is useful where frequent rotation or repositioning of the flange is required. The combination of alloy performance and the lapped joint geometry makes these flanges particularly attractive in piping systems connected to lined equipment, specialist valves, and in skid packages where assembly and orientation flexibility is important.
Synergy positions itself as a global stockist and exporter, serving markets across the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada) and multiple regions in Africa and beyond. Their inventory approach is designed to support both one-off emergency orders and regular project deliveries — offering small-quantity availability from stock as well as planned bulk shipments for EPC and fabricator clients. They also handle logistics, export documentation, and customs facilitation to simplify cross-border procurement.
Types Of Flanges manufacturer
Typical end-use industries for Hastelloy C-276 lapped joint flanges supplied by Synergy include chemical processing, chlor-alkali, pulp & paper, pollution control (flue gas desulfurization), offshore systems, power generation, and specialty process skids. Buyers looking for long service life in corrosive or mixed-acid environments choose C-276 because it reduces downtime and maintenance costs relative to many alternative materials. For procurement, Synergy can provide technical support on flange selection, dimensioning to meet ASME/EN standards, lead-time options, and certification packages to match project specifications.
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.
