Api 609 standard

It is also applicable to pressure designations of Class , Class , Class , Class and Class The scope of this RP includes the inspection and repair of automatic pressure-relieving devices commonly used in the oil and petrochemical industry. Pressure relief devices protect a vessel against overpressure only; they do not protect against structural failure when the vessel is exposed to extremely high temperatures such as during a fire. Atmospheric and low-pressure storage tanks covered in API and pressure vessels used for the transportation of products in bulk or shipping containers are not within the scope of this standard. These figures are to be used only for the purpose of establishing standard nomenclature for valve components - other floating and trunnion designs also exist.

The performance requirements of this document are intended to establish standard limits of acceptability regardless of size or pressure rating.

This publication covers such automatic devices as pressure-relief valves, pilot-operated pressure-relief valves, rupture disks, and weight-loaded pressure-vacuum vents. This standard specifies the requirements for corrosion-resistant bolted bonnet gate valves meeting the requirements of Standard Class, ASME B It is the purpose of this document to establish the requirements for testing and evaluating the pressure-containing performance of API Specs 6A amd 6D valves when exposed to standxrd.

API STANDARD CERTIFICATION - Italvalv

Intended to set guidelines for continuous flow gas lift installation designs using injection pressure operated valves. This standard specifies the requirements for metal ball valves suitable for petroleum, petrochemical, and industrial applications that have: It covers bellows stem seal type testing requirements.

This standard also provides additional requirements for plug valves that are in full conformance to the requirements of ASME B Category B-ASME Class and pressure-temperature rated butterfly valves that have an offset stancard and either an eccentric or a concentric disc configuration.

This standard describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs.

Applies to repair, testing, and setting gas lift valves and reverse flow check valves. The following two categories of butterfly valves are included.

This standard sets forth the requirements for the following gate valve features: It presents guidelines related to the repair and reuse of valves; these practices are intended to serve both repair shops and operators. It also includes sizing procedures ztandard methods based on steady state flow of Newtonian fluids. The commonly used gas pressure-operated bellows valve is also covered.

Flanged, Lug, Wafer and Butt-welding. Those seeking these requirements should see APIwhich gives the requirements for a quality control system and specifies that the repair organization maintain and document a sttandard program ensuring that personnel are qualified.

This standard covers design, materials, face-to-face dimensions, pressure-temperature ratings, and examination, inspection and test requirements for gray iron, ductile iron, bronze, steel, nickel-based alloy, or special alloy butterfly valves that provide tight shutoff in the closed position.

This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems. API covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated e.

Valve Standards

It covers gas, vapor, steam, two-phase and incompressible fluid service; it does not cover special applications that require unusual installation considerations. This International standard specifies the requirements for a heavy-duty series of bolted bonnet steel gate valves for aapi refinery and related applications where corrosion, erosion and other service conditions would indicate a need for full port openings, heavy wall sections and large stem diameters.

Applies to pressure class designations: This standard applies to the sizing and selection of pressure relief devices used in refineries and related industries for equipment that has a maximum allowable working pressure of 15 psig kPag or greater. It includes provisions for the following valve characteristics.

Valve standards of the American Petroleum Institute (API).

The only purpose of these figures is to identify part names. Fires of greater duration are considered to be of a major magnitude with consequences greater than those anticipated 6009 this test. This standard covers design, materials, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for metallic plug valves.

Common piping components, valve types, pipe joining methods, inspection planning processes, inspection intervals and techniques, and types of records are described to aid the inspector in fulfilling their role implementing API This publication does not cover training requirements for mechanics involved in the inspection and repair of pressure-relieving devices.

The standard nomenclature for valve parts is shown in Annex B. This standard applies to floating seat-supported ball Figure B.

This International Standard specifies fire type-testing requirements and a fire type-test method for stanfard the pressure-containing capability of a valve under pressure during and after the fire test.

This document establishes acceptable levels for leakage through the test valve and also external leakage after exposure to a fire for a 30 minute time perioud.
