Stainless Steel Pipeline Connector

The Stainless Steel Pipeline Connector combines a rubber joint body with stainless steel flanges in one flexible, flanged connection. It is installed between pumps, chillers, water-treatment equipment, process skids, and pipelines in municipal water, food processing, purified-water, chemical, offshore, and commercial building systems.

1. Durable flange interface in wet environments. The all-stainless connection does not depend on a painted carbon-steel surface that can chip and rust. In washdown areas, coastal installations, and water-purification rooms, the sealing surface is easier to inspect and keep in serviceable condition.

2. Controlled movement at rigid equipment connections. The one-piece reinforced sphere carries thermal movement, vibration, and minor offset through the flexible body. Less cyclic stress reaches the stainless pipework and equipment nozzles.

3. Separated flow path for clean or corrosive service. A compatible inner barrier separates the conveyed medium from the connector's structural parts. Clean or corrosive fluids are therefore less likely to cause contamination or material attack, while the external stainless connection remains unchanged.

• Nominal diameter can be selected from DN15 to DN4000 with PN6 to PN40 pressure ratings. SS304 or SS316 flanges can be machined to DIN, ANSI, JIS, or GB drilling.
• Food-grade EPDM, NR, NBR, and PTFE-lined constructions are available. Standard service is -15 to +80°C, with special compounds for -30 to +150°C and optional extended face-to-face length.

Incoming stainless flanges are checked for material grade, bolt-circle dimensions, thickness, flatness, and sealing-face condition. Rubber compound batches are verified before molding. Cord placement and vulcanization parameters are monitored during production. Each finished connector is inspected for surface defects and dimensional conformity, then pressure-tested at 1.5 times the ordered working pressure. Flange faces are protected after the unit passes final inspection. Customer-appointed third-party inspectors are accepted.
