Can the Shell clamp for steam EN 14423 (DIN 2826) for VSS, MSS, FSS and SSF type ends be used with hoses thicker than the clampâs specified wall thickness range?

No. The Shell clamp for steam EN 14423 (DIN 2826) for VSS, MSS, FSS and SSF type ends must be selected so that the hoseâs outer diameter (determined by internal diameter and wall thickness) falls within the clampâs specified nominal range. Using the clamp on a hose with a wall thicker than the clampâs specified wall-thickness range risks inadequate seating, poor sealing, uneven pressure distribution, bolt overstress or clamp deformation, and possible leakage or failure under steam pressure and high temperature. For safe, reliable operation up to the stated limits (â¤ +230Â°C, working pressure indications as given), choose a clamp size whose nominal range accommodates the actual hose outer diameter; do not use the clamp beyond its specified wall-thickness/OD range. If in doubt, consult TUBES INTERNATIONALÂ® or the manufacturer for alternative clamps or custom solutions.

How should I choose a Shell clamp for steam EN 14423 (DIN 2826) for VSS, MSS, FSS and SSF type ends based on hose internal diameter and wall thickness?

Shell clamp for steam EN 14423 (DIN 2826) for VSS, MSS, FSS and SSF type ends Choose the clamp by matching the hoseâs internal diameter and wall thickness to the clampâs nominal size so the hoseâs outer diameter falls within the clampâs specified range. Steps: 1. Measure hose internal diameter (ID) and wall thickness; calculate outer diameter (OD = ID + 2Ãwall thickness). 2. Select the clamp nominal size whose OD range includes your calculated OD. 3. For initial assembly use long auxiliary screws to achieve preliminary tightening. 4. Pick material per application: brass clamps with galvanized screws/nuts or AISI 316 stainless steel clamps with stainless hardware for higher corrosion resistance and up to +230Â°C operation. 5. Verify working pressure compatibility (up to 18 bar at +210Â°C saturated steam) and consult TUBES INTERNATIONALÂ® for non-steam applications.

Can Shell clamp for steam EN 14423 (DIN 2826) for VSS, MSS, FSS and SSF type ends be reused after exposure to +230Â°C and saturated steam?

Shell clamp for steam EN 14423 (DIN 2826) for VSS, MSS, FSS and SSF type ends can be reused after exposure to +230Â°C and saturated steam? Yes. with conditions. The clamp is manufactured from brass or AISI 316 stainless steel, with screws/nuts galvanized steel (for brass clamps) or stainless steel (for stainless clamps), and is rated for operation up to +230Â°C and saturated steam (working pressure specified 18 bar at +210Â°C). These specifications indicate the design materials and rating allow use at high temperature and steam exposure. Reuse is acceptable provided all of the following are verified after exposure: - Visual inspection: no cracking, distortion, burn marks, severe corrosion, pitting or loosening of any parts. - Fasteners: screws and nuts operate smoothly, threads intact, no hydrogen embrittlement, galling or significant corrosion; replace galvanized fasteners if plating has degraded. - Seal/fit: clamp still secures the hose within the specified outer diameter range and achieves required clamping force without overâtorque. - Material integrity: stainless steel parts show no sensitization, intergranular corrosion or mechanical weakening; brass shows no dezincification or embrittlement. - Functional test: clamp can be tightened to required preload using long auxiliary screws for preliminary tightening and holds under working pressure and temperature in a controlled test or during a supervised trial run. If any doubt exists about material degradation, thread damage, distortion or loss of mechanical properties, replace the clamp. For safetyâcritical or highâpressure steam systems, replacing clamps after sustained exposure to +230Â°C and saturated steam is the conservative and recommended practice.
