Can UNI-FLEX S pipe clamp with EPDM gasket and stainless steel (AISI 316Ti) housing be reused after a successful 150% pressure test?

Yes. UNI-FLEX S pipe clamp with EPDM gasket and stainless steel (AISI 316Ti) housing can be reused after a successful 150% pressure test. For non-marine industrial/static applications the clampâs maximum operating pressure is 25 bar and it is designed with a safety factor of 1.5:1; a one-time pressure test at 150% of the maximum operating pressure, if passed, permits multiple subsequent reuses. Ensure the clamp was installed on a round steel pipe with the minimum wall thickness, fitted according to the manufacturerâs instructions, and tightened with the specified torque wrench. Note: for shipbuilding/marine PN16 applications the design uses a 4:1 safety factor and a one-time 4Ã pressure test; after that test the clamp must not be reused.

Can the UNI-FLEX S pipe clamp with EPDM gasket and stainless steel (AISI 316Ti) housing be used for light chemicals and air under marine PN16 conditions?

Yes. The UNI-FLEX S pipe clamp with EPDM gasket and stainless steel (AISI 316Ti) housing is suitable for light chemicals and air under marine PN16 conditions. It is explicitly designed for water, water-based fluids, sewage, light chemicals and air; material AISI 316Ti and A4-80 fasteners provide marine-grade corrosion resistance. EPDM sealing is compatible with many light chemicals and air and the operating temperature range (-30Â°C to +125Â°C) covers typical marine environments. For PN16 shipbuilding use the clamp meets the PN16 rating with a 4:1 safety factor (single pressure test at 4Ã maximum; clamp not reusable after that test). Ensure installation on round steel pipes with minimum wall thickness, follow manufacturer torque and fitting instructions, and confirm chemical compatibility of EPDM with specific fluids used.

Can UNI-FLEX S pipe clamp with EPDM and stainless steel (AISI 316Ti) housing be used for sewage systems?

Yes. The UNI-FLEX S pipe clamp with EPDM seal and AISI 316Ti stainless steel housing is suitable for sewage systems. Reasons: - Application list explicitly includes sewage. - EPDM sealing is chemically compatible with typical sewage and wastewater (resistant to water, sewage, many dilute chemicals). - AISI 316Ti housing and A4-80 screws provide excellent corrosion resistance for aggressive or coastal environments common in sewage installations. - Operating temperature range (â30Â°C to +125Â°C) covers normal sewage conditions. - Pressure ratings (PN16 and max 25 bar) and provided safety factors meet both marine/shipbuilding and general industrial/static use when installed per instructions and tightened with the specified torque. Note the PN16 safety regime requires a one-time test at 4Ãpressure (clamp not reusable afterward); the 25 bar regime allows reuse after 1.5Ã pressure test. - Ensure clamps are fitted on round steel pipes with minimum wall thickness, using correct installation procedure and torque; select appropriate pin version (standard or âLâ incomplete pins) for the specific application. If your sewage system involves aggressive chemicals outside typical wastewater, extreme temperatures, or nonstandard pipe materials/conditions, verify chemical compatibility and consult manufacturer specifications.

Additional information

Material	SS – stainless steel

UNI-FLEX S type pipe clamp designed for connecting and repairing metal and plastic pipes (non-fixed axial connection, flexible – only with rubber gasket). Application: water, water-based fluids, sewage, light chemicals, air. Material version: AISI 316Ti steel (housing, screws – class A4-80, solid pins). Sealing: EPDM rubber. Operating temperature: from -30°C to +125°C. Nominal pressure: PN 16 (pressure class for shipbuilding and marine applications; safety factor 4:1, assuming a positive result from a one-time pressure test at four times the maximum pressure, after which the clamp cannot be reused). Maximum operating pressure: 25 bar (for other industrial applications and static conditions; safety factor 1.5:1, assuming a positive result from a pressure test at 150% of the maximum operating pressure, after which the clamp can be reused multiple times). The working pressure values apply to the installation of clamps on round steel pipes with a minimum wall thickness, installation according to the instructions, and tightening with a torque wrench specified on the clamp. Available version with incomplete pins, version “L” (example index: UN-FLEX-L-…).
