Steel gate, globe and check valves for sizes DN 100 and smaller, for the petroleum and natural gas industries (ISO 15761:2020)

This document specifies the requirements for a series of compact steel gate, globe and check valves for petroleum and natural gas industry applications.
It is applicable to valves of:
—     nominal sizes DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80 and 100,
—     corresponding to nominal pipe sizes NPS ¼, ⅜, ½, , 1, 1¼, 1½, 2, 2½, 3 and 4,
—     pressure designations PN 16, 25, 40, 63, 100, 250 and 400, and
—     pressure designations Class 150, 300, 600, 800, 1 500 and 2 500.
Class 800 is not a listed class designation, but is an intermediate Class number widely used for socket welding and threaded end compact valves covered by this document. There is no equivalent PN designation.
This document includes provisions for the following valve characteristics:
—     outside screw with rising stems (OS & Y): in sizes 8 ≤ DN ≤ 100;
—     inside screw with rising stems (ISRS): in sizes 8 ≤ DN ≤ 65 with a pressure designation PN ≤ 100 or Class ≤ 800;
—     socket welding or threaded ends: in sizes 8 ≤ DN ≤ 65;
—     flanged or butt-welding ends excluding flanged end Class 800;
—     bonnet joint construction that is bolted, welded or threaded with seal weld;
—     bonnet joint construction that uses a union nut with a pressure designation PN ≤ 45 or Class ≤ 800;
—     body seat openings;
—     materials: as specified;
—     testing and inspection.
This document covers valve end flanges in accordance with EN 1092-1 and ASME B16.5 and valve body ends having tapered pipe threads in accordance with ISO 7-1 or ASME B1.20.1. It is applicable to extended body construction in sizes 15 ≤ DN ≤ 50 with pressure designations Class 800 and Class 1 500 and to bellows and bellows assembly construction adaptable to gate or globe valves in sizes 8 ≤ DN ≤ 50. Also covered are requirements for bellows stem seal type testing.

Robinets-vannes, robinets à soupape et clapets de non retour en acier de dimensions DN 100 et inférieures, pour les industries du pétrole et du gaz naturel (ISO 15761:2020)

Le présent document spécifie les exigences pour une série de robinets-vannes, robinets à soupape et clapets de non-retour, en acier massif, pour des applications dans les industries du pétrole et du gaz naturel.
Elle est applicable aux appareils de robinetterie:
—     de diamètres nominaux DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80 et 100,
—     correspondant aux dimensions nominales de tuyauterie NPS ¼, ⅜, ½, , 1, 1¼, 1½, 2, 2½, 3 et 4,
—     affichant des désignations de pression PN 16, 25, 40, 63, 100, 250 et 400, et
—     affichant des désignations de pression Class 150, 300, 600, 800, 1 500 et 2 500.
Class 800 n'est pas une désignation de pression Class énumérée. C'est un numéro Class intermédiaire largement utilisé pour les appareils de robinetterie en acier massif à extrémités à emboîter et à souder et extrémités filetées couverts par le présent document. Il n'existe pas de désignation PN équivalente.
Le présent document contient des dispositions relatives aux caractéristiques des appareils de robinetterie suivants:
—     tiges montantes à filetage extérieur (OS & Y): de dimensions 8 ≤ DN ≤ 100;
—     tiges montantes à filetage intérieur (ISRS): de dimensions 8 ≤ DN ≤ 65 avec une désignation de la pression PN ≤ 100 ou Class ≤ 800;
—     extrémités à emboîter et à souder ou extrémités filetées, de dimensions 8 ≤ DN ≤ 65;
—     extrémités à brides ou extrémités à souder en bout, excepté les extrémités à brides de Class 800;
—     assemblage du chapeau qui est boulonné, soudé ou fileté avec une soudure d'étanchéité;
—     assemblage du chapeau utilisant un écrou de raccord union avec une désignation de pression correspondant à PN ≤ 45 ou Class ≤ 800;
—     ouvertures au siège de l'appareil de robinetterie;
—     matériaux: comme spécifié;
—     essais et contrôle.
Le présent document couvre les extrémités à brides des appareils de robinetterie conformes à l'EN 1092-1 et à l'ASME B16.5, ainsi que les extrémités de corps des appareils de robinetterie avec des filetages de tuyauterie coniques conformes à l'ISO 7-1 ou à l'ASME B1.20.1. Il s'applique aux constructions à corps rallongés de dimensions 15 ≤ DN ≤ 50 avec des désignations de pression Class 800 et Class 1 500, et aux constructions à soufflets et aux joints à soufflets adaptables aux robinets-vannes ou aux robinets à soupape de dimensions 8 ≤ DN ≤ 50. Il couvre également des exigences applicables aux essais de type des étanchéités de tige par soufflet.
