T/JSJXXH 022-2024 Petroleum Scientific Research Instruments, Intermediate Container

Scope

Scope: This document specifies the terms and definitions, models, basic parameters, structural types, technical requirements, test methods, marking, packaging, transportation, and storage of intermediate containers for petroleum scientific research instruments. This document is applicable to the design, manufacture, and inspection of intermediate containers for petroleum scientific research instruments with a design pressure of 16MPa to 50MPa, a design temperature not exceeding 180℃, and a volume of 0.2L to 24L. Main technical content: This standard specifies the terms and definitions, models, basic parameters, structural types, technical requirements, test methods, marking, packaging, transportation, and storage of intermediate containers for petroleum scientific research instruments. The formulation and release of this standard will help improve the manufacturing level of intermediate containers for petroleum scientific research instruments and promote high-quality development of the industry. Technical requirements: - Appearance: The outer surface of the intermediate container should be smooth, without indentations, burrs, or grooves. - Surface roughness: The inner wall Ra ≤ 1.6μm, and the outer wall Ra ≤ 3.2μm. - Welding seams: No visible defects such as undercutting, slagging, or porosity; the welding quality shall comply with the requirements of NB/T47013.2-2015, section 6.3. - Pressure-bearing capacity: When the intermediate container is subjected to 1.25 times the design pressure, there should be no leakage, deformation, or abnormal noise. - Elimination of internal stress: Important castings, forgings, and welded parts such as frames and worktables should eliminate internal stress.
