Synergy Engineering Solutions is a prominent manufacturer, stockist, and exporter of UNS N07718 Inconel 718 lapped joint flanges, serving a global clientele across regions including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and various countries in Africa. Their extensive product range encompasses various flange types such as slip-on, weld neck, blind, threaded, socket weld, and lap joint, adhering to international standards like ASTM B564, ASME SB564, ANSI B16.5, and DIN. These flanges are available in sizes ranging from 1/2" to 60" and pressure classes from 150# to 2500#, suitable for diverse industrial applications.
Inconel 718 (UNS N07718) is a high-strength, corrosion-resistant nickel-chromium alloy renowned for its exceptional mechanical properties at elevated temperatures. This precipitation-hardened alloy offers excellent weldability and formability, making it ideal for aerospace, automotive, and marine engineering applications. Its remarkable resistance to oxidation and high-temperature environments ensures reliability in extreme conditions.
The lapped joint flange design is particularly advantageous in applications requiring frequent disassembly for maintenance or inspection. This design consists of two components: a stub end welded to the pipe and a loose backing flange that can be rotated to align bolt holes, facilitating easy alignment and assembly. This feature is especially beneficial in systems where components need to be replaced or serviced regularly.
Synergy Engineering Solutions ensures the highest quality standards in their manufacturing processes. Their Inconel 718 flanges undergo rigorous testing, including Positive Material Identification (PMI), chemical analysis, mechanical testing, and microstructural examination, to confirm compliance with international specifications and customer requirements.
The company's global reach is supported by a robust logistics network, allowing timely delivery of products worldwide. Their commitment to quality, customer satisfaction, and timely delivery has established Synergy Engineering Solutions as a trusted partner for industries requiring high-performance flanges.
Whether you need single prototype stub ends with backing flanges, stocked inventory for maintenance turnarounds, or long-term procurement for multi-site projects, Synergy positions itself as a turnkey partner for UNS N07718 Inconel 718 Lapped Joint Flanges.
