ISA 75.19.01

Hydrostatic Testing of Control Valves

Organization:
ISA - International Society of Automation
Year: 2013

Abstract: This standard applies to control valves having bodies, bonnets, cover plates, and bottom flanges made of carbon steel, low alloy and high alloy (stainless) steel, nickel-base alloy, cast iron, and ductile iron.
This standard establishes requirements and definitions for standard hydrostatic shell testing of control valves by the valve manufacturer to prove the structural integrity and leak tightness of the valves' pressure retaining parts, including any closure parts such as the valve body to bonnet joint, but excluding packings, bellows or other moving seals, and packing leakoff/purge/vent port connections. Bellows or similar moving stem seals may be pressure tested after assembly at a pressure to be agreed upon by the valve manufacturer and the purchaser. The requirements of this standard do not cover pneumatic and hydraulic actuators and regulators.
This standard describes and specifies the specific circumstances of hydrostatic shell testing of control valves and is in accordance with the hydrostatic testing requirements of ASME B16.1, ASME B16.34 and ASME B16.42 with the exception that the test requirements of paragraph 4.8 are not allowed by ASME B16.34.
WARNING – SERIOUS BODILY HARM CAN BE CAUSED BY HIGH VELOCITY LEAKS THROUGH THE SHELL OR SEALS, RESULTING FROM THE ENERGY STORED IN THE PRESSURIZED FLUID AND CONTAINMENT EQUIPMENT. CARE SHOULD BE EXERCISED TO ENSURE THE SAFETY OF TEST AND INSPECTION PERSONNEL. SPECIFIC SAFETY REQUIREMENTS FOR CONDUCTING HYDROSTATIC TESTING AND INSPECTION ARE NOT WITHIN THE SCOPE OF THIS STANDARD.
