Nine valve industry standards will be implemented from June 1st, 2016

recently, the official website of the Ministry of industry and information technology of the people's Republic of China issued the "2016 No. 3" announcement, and the reciprocating vacuum pump approved by the Ministry of industry and information technology has a total of 643 industry standards, including 9 valve industry standards, which will be implemented from June 1st, 2016, The official website of the Ministry of industry and information technology of the people's Republic of China issued the "2016 No. 3" announcement. The reciprocating vacuum pump approved by the Ministry of industry and information technology has a total of 643 industry standards, including 9 industry standards related to valves, which will be implemented from June 1, 2016

these nine valve industry standards are:

1, flange and butt welded corrosion-resistant gate valves (jb/t). This standard specifies the pressure temperature rating, design, materials, test methods, inspection rules, signs, supplies, etc. of full-diameter corrosion-resistant gate valves used in process pipeline applications

this standard is applicable to gate valves with nominal pressure of class150 ~ CLASS600 (PN20 ~ PN100), 2 key materials without localization, nominal size of DN15 ~ DN600, which are characterized by connecting the bonnet with studs (or bolts) at the moment when he steps down the gangway, rising stem support, lifting valve rod, non lifting handwheel, wedge or parallel, single or double gate, valve seat with metal surface, flange or butt welding connection. Applicable media are petroleum and petroleum related products, natural gas, steam, etc

2. Technical conditions of hydraulic ball valve for water turbine inlet (jb/t). This standard specifies the composition, typical structural type and model, technical requirements, inspection and test methods, inspection and acceptance rules, marks, shipping and storage of hydraulic ball valve for water turbine inlet

this standard is applicable to inlet ball valves with nominal diameter not greater than 5000mm

3. Technical conditions for liquefied natural gas valves (jb/t). This standard specifies the terms and definitions, technical requirements, inspection, test methods, inspection rules, marks, painting, packaging, transportation and storage of gate valves, globe valves, check valves, ball valves and butterfly valves for liquefied natural gas

this standard is applicable to flanges and welded valves with nominal pressure of PN16 ~ PN250, nominal size of DN15 ~ DN1200, pressure class of class150 ~ class1500, nominal size of nps1/2 ~ nps48, and working medium of liquefied natural gas

other low-temperature valves with temperature higher than -162 ℃ can also be used by reference

4. Performance test of valves for liquefied natural gas (jb/t). This standard specifies the terms and definitions, test items, normal temperature performance test, low temperature performance test, test methods, test procedures, leakage rate and other requirements of performance test of valves for liquefied natural gas

this standard is applicable to flanges with nominal pressure of PN16 ~ PN250, nominal size of DN15 ~ DN1200, pressure class of 150 ~ class 1500, nominal size of nps1/2 ~ nps48 and working medium of liquefied natural gas and gate valves, globe valves, check valves, ball valves and butterfly valves connected by welding

other types of valves can also be used by reference

5. Butterfly valves for liquefied natural gas (jb/t). This standard specifies the structural type, technical requirements, test methods, inspection rules, marks, packaging, storage, transportation and supply of steel butterfly valves for liquefied natural gas

this standard is applicable to butterfly valves for liquefied natural gas with nominal size of DN80 ~ DN1200, nominal pressure of PN16 ~ PN100, nominal size of nps3 ~ nps48 and pressure rating of class150 ~ CLASS600

other low-temperature butterfly valves with temperature higher than -162 ℃ can also be used by reference

6. Stop valves and check valves (jb/t) for liquefied natural gas. This standard specifies the structural types, technical requirements, test methods, inspection rules, marks, packaging, storage and transportation of stop valves and lift check valves for liquefied natural gas, and compiles the construction technical guidelines

this standard is applicable to flange and welded stop valve, lift check valve and swing check valve whose working medium is liquefied natural gas

other stop valves and check valves with temperature higher than -162 ℃ can also be used by reference

7. Ball valves for liquefied natural gas (jb/t). This standard specifies the structural type, technical requirements, test methods, inspection rules, marks, packaging, storage and transportation of ball valves for liquefied natural gas

this standard is applicable to flange and welded ball valves with nominal pressure of PN16 ~ PN250, nominal size of DN15 ~ DN700, pressure class of class150 ~ class1500, nominal size of nps1/2 ~ nps28, and working medium of liquefied natural gas

other low-temperature ball valves with temperatures higher than -162 ℃ can also be used by reference

8. Gate valves for liquefied natural gas (jb/t). This standard specifies the structural type, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of gate valves for liquefied natural gas

this standard is applicable to flanges and welded gate valves with nominal pressure of PN16 ~ PN250, nominal size of DN25 ~ DN600, pressure class of class150 ~ class1500, nominal size of nps1 ~ nps24, and working medium of liquid natural gas

other ecological labels with temperatures higher than -162 ℃ include the sustainability evaluation composed of 36 standards. Low temperature gate valves can also be used by reference

9. Cup valve (jb/t) for converter gas dry dedusting system. This standard specifies the terms and definitions, structural types, models and parameters, technical requirements, tests and inspections, inspection rules, marks, shipping and storage of cup valve for converter gas dry dedusting system

this standard is applicable to the cup valve used in the dry dedusting system of converter gas with the nominal pressure not greater than PN 2.5, the nominal size of DN500 ~ dn2800, the medium of which is converter gas, and the service temperature not higher than 200 ℃
