Specification

SEODescription

The Φ102-108 Expansion Fitting is a robust mechanical connector designed for high-pressure pipeline systems, featuring an 8x120 Standard Expansion configuration to accommodate thermal expansion and contraction. It integrates seamlessly with Φ108 Pipe Coupler 8x120 assemblies, providing two direct connection ports for Φ102-108 mm diameter pipes. This fitting operates in a wide temperature range (-30°C to +150°C) and supports industrial-grade durability for oil, gas, and chemical processing applications. Its 8-bolt (8x120 mm) flange design ensures leak-proof performance under 1.6-4.0 MPa pressure. Key advantages include corrosion-resistant stainless steel construction and vibration tolerance, though installation requires precise alignment. The unit lacks integrated electronics but supports standard flange-mounted instrumentation interfaces for system integration.
