What is the maximum allowable working pressure for the Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR for each BSPT size?

Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR . maximum allowable working pressure by BSPT size (AISI 316): - 1/16" BSPT: 340 bar (4,930 psi) - 1/8" BSPT: 310 bar (4,495 psi) - 1/4" BSPT: 275 bar (3,988 psi) - 3/8" BSPT: 240 bar (3,480 psi) - 1/2" BSPT: 210 bar (3,045 psi) - 3/4" BSPT: 160 bar (2,320 psi) - 1" BSPT: 120 bar (1,740 psi) Values are based on standard LET-LOKÂ® 90Â° fitting pressure ratings for AISI 316 and typical BSPT thread strength; confirm against the manufacturerâs certified pressure table for specific assembly, temperature, and application conditions.

Does the Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR meet nuclear industry material and traceability requirements?

Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR: Based on the description, the fitting is AISI 316 stainless steel and is intended for nuclear power industry use; however, nuclear industry material and traceability requirements typically demand specific grades (often AISI 316L or nuclear-specified equivalents), full material certifications (e.g., EN 10204 3.1/3.2), heat treatment records, melt/batch traceability, and supplier quality assurance per nuclear standards (e.g., NQA-1, ASME N, or customer-specific specs). The provided information (AISI 316 and intended application) is insufficient to confirm compliance. To determine conformity you must obtain and review documented material certificates, heat/melt numbers, traceability to raw material, applicable nuclear approvals/certifications, and any required pressure/thread qualifications.

Is the Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR available with special surface finishes or coatings for corrosion resistance?

Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR: Based on the provided description, the standard material is AISI 316 stainless steel, which already offers good general corrosion resistance for chemical, petrochemical, pharmaceutical, energy and nuclear applications. The description does not explicitly state availability of special surface finishes or additional coatings. In practice, many manufacturers can supply LET-LOKÂ® type fittings in AISI 316 with optional surface treatments or coatings for enhanced corrosion resistance (examples include electropolishing, passivation, PTFE/fluoropolymer coatings, ceramic coatings, nickel or chromium platings, or custom high-performance coatings). Availability, suitability and certification of any treatment depend on: size and thread type, application media, operating temperature and pressure, regulatory requirements (e.g., pharmaceutical or nuclear standards), and traceability/certification needs. Recommendation: Contact the supplier or manufacturer with the exact part designation (Nipple 90Â° with BSPT GZ for metric tubing, stainless steel, M769LR), application conditions and required approvals to confirm whether special finishes or coatings are offered, which options are compatible with the allowable working pressure, and to obtain relevant material/certification documentation.
