Is the Straight fitting with GW BSP for metric pipe, stainless steel, M766LG compatible with chemical and nuclear applications and what are its maximum allowable pressures?

Straight fitting with GW BSP for metric pipe, stainless steel, M766LG Format Yes . the Straight fitting with GW BSP for metric pipe, stainless steel, M766LG is intended for chemical and nuclear applications. It is a LET-LOKÂ® straight coupling with internal BSP thread for metric tubing, made of AISI 316 stainless steel, and is primarily designed for use in chemical, petrochemical, pharmaceutical, energy, nuclear power and process engineering industries. Maximum allowable working pressure depends on the tubing outer diameter and wall thickness; the permissible working pressure is determined from those tube dimensions (refer to the tubing pressure table provided with the product). Because pressure limits vary by tube size and schedule, a specific pressure value cannot be given without the exact tube OD and wall thickness. For accurate maximum allowable pressures, consult the attachment/table of permissible working pressures corresponding to the chosen metric tubing dimensions.

Does the Straight fitting with GW BSP for metric pipe, stainless steel, M766LG meet ASME/B31.3 and nuclear pressure codes?

Straight fitting with GW BSP for metric pipe, stainless steel, M766LG: Based on the provided description (LET-LOKÂ® straight coupling with internal BSP thread for metric tubing, material AISI 316, intended for chemical, petrochemical, pharmaceutical, energy, nuclear power and process engineering; permissible working pressure determined by tube OD and wall thickness), no definitive statement can be made that it universally "meets ASME B31.3 and nuclear pressure codes." Compliance depends on specific design verification, applicable code editions, required safety factors, welds/assembly methods, testing, documentation (material traceability, NDT, pressure tests), and project-specific engineering review. If manufactured and tested per the requirements and documented to the applicable ASME B31.3 and relevant nuclear codes, it can be acceptable; otherwise, formal certification/engineering approval is required.
