Is Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK suitable for use in nuclear power applications and what certifications confirm this?

Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK is described as a LET-LOKÂ® external BSP thread (seal LOK) connector for metric tubing, intended specifically for nuclear power among other industries, and manufactured from AISI 316 stainless steel. That makes it conceptually suitable for many nuclear applications, provided its mechanical and material properties meet the project-specific requirements. Key points to confirm suitability: - Material: AISI 316 stainless steel is commonly accepted in nuclear and process industries for corrosion resistance, but final acceptance depends on the specific environment (radiation, temperature, neutron activation) and nuclear regulator requirements. - Pressure rating: Permissible working pressure is determined by tube outer diameter and wall thickness per the product documentation . verify the actual tubing dimensions and operating pressure match the stated limits. - Intended use: The product description explicitly lists nuclear power as an application area, supporting suitability for that sector. Certifications and documentation to request/verify: - Material certificates (EN 10204/3.1 or 3.2) for AISI 316 traceable to heat number. - Pressure/strength test data and applicable dimensional/pressure ratings matching your tubing. - Manufacturer quality management certification (e.g., ISO 9001). - Compliance or approvals specific to nuclear industry standards or customer nuclear QA programs (e.g., NQA-1, ASME N/A, or supplier qualification to utility-specific requirements) if required by the plant. - Any additional approvals for nuclear use (e.g., certificate of compliance with nuclear procurement specifications, testing for radiation/temperature resilience) as requested by the end user. Conclusion: Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK can be suitable for nuclear power applications, but acceptance requires verification of pressure ratings, material certificates (EN 10204), and any nuclear-specific quality/qualification certifications demanded by the plant or regulator.

Can Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK be used with tubing of varying wall thicknesses and how does that affect permissible working pressure?

Yes. Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK can be used with tubing of varying wall thicknesses. The permissible working pressure depends on the tube outer diameter and its wall thickness: thicker walls allow higher permissible pressures, thinner walls reduce allowable pressure. Refer to the detailed pressure rating table (attachment) for exact permissible working pressures for each OD and wall-thickness combination. Material: AISI 316 stainless steel.

What temperature range can Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK safely operate within?

Straight fitting with GZ BSP for metric pipe, stainless steel, M768LOK can safely operate within the temperature range typical for AISI 316 stainless steel fittings used with LET-LOKÂ® (seal LOK) connections in chemical, petrochemical, pharmaceutical, energy, nuclear power and process engineering applications. For AISI 316 stainless steel, the recommended continuous service temperature range is approximately -196 Â°C (cryogenic conditions with appropriate tubing) up to about +400 Â°C for standard service; short-term or limited-service exposures can reach higher temperatures depending on system design and pressure. The actual safe operating temperature for a specific installation must also account for the tube material, wall thickness, pressure rating (permitted working pressure determined by outer diameter and wall thickness), sealing media, and any thermal cycling or corrosive conditions. Consult the detailed pressureâtemperature limits provided in the product documentation/attachment and applicable standards to determine the exact permissible temperature for your combination of tubing and operating pressure.
