What is the recommended torque for installing the WE-BT angle screw connection, stainless steel (AISI 316) to ensure a safety factor of 2.5:1?

Recommended installation torque for the WE-BT angle screw connection, stainless steel (AISI 316) to achieve a safety factor of 2.5:1 is not directly defined by the brief DIN 2353 description alone . it depends on thread size (metric or BSPT), series (LL, L, S), bolt/thread material and pitch, and sealing method. However, practical guidance: - For light series (L / LL) using common metric sizes (e.g., M14âM22) in AISI 316, typical assembly torques to give a conservative safety factor â2.5 are in the approximate ranges: - LL (very light): M10âM12 â 25â45 Nm - L (light): M12âM16 â 45â90 Nm - S (heavy): M16âM22 â 90â180 Nm - For BSPT/external pipe threads of similar diameters, use comparable torque ranges but reduce torque ~10â20% when using PTFE tape or anaerobic sealant to avoid overstressing threads. Important: these are approximate starting values. For exact recommended torque to guarantee a 2.5:1 safety factor, consult the manufacturerâs torque tables for WE-BT angle screw connection, DIN 2353 dimension/series and the specific thread size and material condition, or calculate from allowable thread stress and clamp load using: Torque = K Ã Clamp load Ã Nominal diameter, with K (nut factor) adjusted for stainless steel and lubricant/sealant (typical K 0.15â0.25). Use measured clamp loads or manufacturer data to verify safety factor.

How should the WE-BT angle screw connection, stainless steel be sealed when using BSPT threads to maintain a 2.5:1 safety factor?

For WE-BT angle screw connection, stainless steel using BSPT threads, seal on the thread is required. Use PTFE (Teflon) tape applied correctly (wrap in direction of thread, 3â5 turns, avoid overfilling) or an anaerobic thread sealant rated for stainless steel and hydraulic service. Ensure assembly torque and engagement follow DIN 2353 recommendations for the WE-BT series (LL, L, S) and achieve the specified 2.5:1 safety factor by verifying correct thread engagement length, proper thread form, and using the specified AISI 316 component materials. After sealing, inspect for full thread contact and test at design pressure to confirm leak-tightness.

Can WE-BT angle screw connection, stainless steel (AISI 316) be used interchangeably across LL, L, and S series while keeping 2.5:1 safety factor?

Yes. but only if the pressure ratings and thread sizes for the specific LL, L, and S parts are individually verified and the weakest (lowest rated) series governs the allowable working pressure to maintain the 2.5:1 safety factor. Explanation: The WE-BT angle screw connection, stainless steel (AISI 316) is built to DIN 2353 24Â° specification and is offered in LL (very light), L (light) and S (heavy) series. Each series has different wall thicknesses and pressure ratings; mechanical strength and burst pressure vary accordingly. The 2.5:1 safety factor is a requirement referenced in the description, so to use components interchangeably you must ensure: - Each mating part (LL/L/S) on both sides of the connection is rated so that the lowest allowable working pressure (AWP) among the assembled components, when multiplied by 2.5, still exceeds the maximum system test/burst pressures expected. - Thread compatibility (metric external and BSPT external as applicable) and sealing method (seal on the thread with PTFE tape or anaerobic sealant) are correct for all sizes/types used together. - The connection size (thread diameter and 24Â° seat geometry) is identical or compatible between the chosen LL, L, and S parts. If you match sizes and limit system pressure to the lowest rated series while maintaining 2.5:1 factor, interchangeable use is acceptable. If any part in the assembly is from a lower-rated series and the system pressure exceeds that partâs allowable working pressure (AWP = burst pressure / 2.5), do not mix. use the higher-rated S series or redesign for sufficient margin. Recommendation: Check manufacturer datasheets for the specific LL, L and S AWP/burst values for the exact size, and base interchange decisions on those numbers.
