Import Api Seals Type C — Buy in Bulk from Supplier in India

API Seals Type C from Expert Engineering are fabricated from Alloy C-276, a nickel-based superalloy renowned for its resistance to corrosion in aggressive chemical environments. The Type C design is tailored for high-temperature refinery and petrochemical applications, where sealing reliability is critical under thermal cycling and pressure fluctuations. The alloy’s typical composition includes 57% nickel, 16% molybdenum and 15.5% chromium, with controlled carbon and silicon levels to minimize grain boundary precipitation.

The seals are engineered for precision fitment, with machined surfaces that meet stringent flatness and roughness criteria to prevent leakage in flanged connections. Alloy C-276 is a standard choice for such seals due to its ability to resist pitting, crevice corrosion and stress corrosion cracking in chloride-rich media. Typical industry specifications for API seals include hardness values of 20-25 HRC and a maximum carbon content of 0.01% to maintain weldability and ductility.

These seals are deployed in refinery units such as catalytic reformers, hydrotreaters and delayed cokers, where exposure to hot hydrogen-rich gases and sulfur compounds is common. Buyers in oil and gas, chemical processing and power generation industries rely on them for pumps, compressors and pressure vessels. For procurement, confirm the MOQ, packaging standards and lead time directly with Expert Engineering, as these details are not provided in the listing.

Expert Engineering is based in Mumbai, Maharashtra, with offices in Mira Road (East) and Goregaon West, serving as a hub for industrial sealing solutions. The supplier holds a harbor trust tier, which confirms its business registration and contact details but does not include advanced verification metrics. The response rate is currently listed as 0%, which may indicate a need for direct outreach to establish communication timelines.

The company’s focus on API seals and corrosion-resistant alloys positions it as a niche provider for refinery and chemical processing industries. While the profile does not disclose certifications, production capacity or client references, buyers can request ISO or SGS compliance documentation to validate quality. The supplier’s location near major Indian ports facilitates efficient export logistics for international buyers.
