Multi-Standard Compliance
Manufacturing Standards
ISO 5208:2015 Industrial Valves — Testing of Pressure - Seal Valves
This standard specifies the methods for pressure testing of industrial valves, including requirements for shell tests, seat tests, etc. It is relevant for ensuring the manufacturing quality and pressure - tightness of the regulator.
ASME B16.34:2021 Valves — Flanged, Threaded, and Welded End
Defines design requirements, pressure - temperature ratings, and materials for valves with different end connections. It guides the manufacturing process to meet the necessary engineering and safety standards.
Flange Structural Length Standards
ISO 5752:1982 Face - to - Face and End - to - End Dimensions of Valves
Provides standardized face - to - face dimensions for flanged valves across various pressure classes. This ensures compatibility and proper installation when connecting with other pipeline components.
ASME B16.10:2021 Face - to - Face and End - to - End Dimensions of Valves
Specifies the dimensions for flanged, butt - welded, and socket - welded valves in ASME - compliant systems, which is important for maintaining the correct structural length of the valve's flanged part.
Flange Face Standards
ASME B16.5:2020 Pipe Flanges and Flanged Fittings
Covers dimensions, pressure ratings, and tolerances for steel flanges. It defines the different types of flange faces (such as raised face, flat face, etc.) and their specific requirements, which are crucial for proper sealing and connection.
ISO 7005 - 1:2019 Pipe Flanges — Part 1: Steel Flanges
Specifies the standards for steel flanges, including the geometry and surface finish of the flange face. This helps ensure consistent quality and interchangeability of flanged components.
Pressure Testing Standards
API 598:2014 Valve Testing
Details the procedures for shell tests, seat tests, and backseat tests for valves. It sets the criteria for acceptable leakage rates and pressure levels during testing to verify the valve's integrity.
BS EN 12266 - 1:2019 Valves — Test Procedures for Valves — Part 1: Pressure Tests
Mandates hydrostatic and pneumatic test procedures for valves, including requirements for test pressure, duration, and inspection methods to ensure the valve can withstand the specified operating pressures.
