HG/T 4584-2014 (English Version) PDF

Scope: This standard specifies the terms and definitions, symbols and codes, dimensions and tolerances, product markings, materials and processes, technical requirements, test methods, inspection rules and signs for isostatically pressed polytetrafluoroethylene-lined pipes and pipe fittings for chemical industry. Packaging, transportation and storage, safety. This standard is applicable to PTFE-lined pipes and pipe fittings with design pressures of -0. 1 MPa ~ 2. 5 MPa and design temperatures - 80 ℃ ~ 250 ℃ for the chemical industry. The PTFE pipe blanks and pipe fitting blanks are formed by isostatic pressing and sintering, and then combined with the metal shell through relaxation installation and flanging.
