Low-temperature insulation lng cylinder testing equipment, mature technology, professional manufacturers to introduce ourselves, Jiangsu Province, east China air separation plant to provide you with complete sets of lng cylinder complete sets of testing equipment, including the interrogation unit, residue recycling, purged with nitrogen, valve test overhaul, mezzanine vacuum degree Detection and fill the vacuum, static evaporation rate detection, leak detection, and other complete sets of testing equipment, process leading domestic system is mature, easy to operate, on line. Welcome to the new and old customers to inquire reviews and low temperature insulation lng cylinder sets Detection Process Description First, the preparations on spot away from open flames or sparks claim 10 meters smoking, open flames, placing versatile appliance, holding test site area well ventilated and avoid direct sunlight, and do not allow the presence of vibration environment II. Confirmation 'cylinders raw data review and record: manufacturing units, cylinder number, manufacturing date, the cylinder type, nominal working pressure, nominal volume, net weight cylinders, maximum filling weight, previous periodic inspection date, gas Bottle-owned vehicles license plate number, etc. '' cylinders using historical information, including cylinders collision, repair, alteration record; cylinder safety accessories, piping, valve repair and replacement records; abnormal cylinder other course appeared Record 'three, visual inspection and check of cylinder structure, geometry check of cylinder head in the form of joint form, weld arrangement, nozzle position, opening the way and check the position of their counterparts in the wrong side of the maximum amount of weld, weld maximum angular degree of compliance with GB24159-2009 "welding insulation cylinder" provides four cylinders combinations of components and safety accessories combined component detection means: filling valve on the gas cylinder at the beginning of the fuel valves, gas shut-off valve, pressure regulator and throttle Its pipeline inspection of cylinders and cylinder body coupled member whether there is the appearance of wear References "TSG R0006-2014 Cylinder Safety Supervision" secure attachment means: a safety valve on the gas cylinder two safety valves , safety valve discharge pipe, vacuum pumping port, pressure gauge and level gauge, etc. Check that all safety valve pressure gauge whether there is not extended-check level off valve catheter if there are five, residue recycling the inner cylinder residue recovery Clean equipment list: 2 more lng gas cylinders, cryogenic liquid turnover for cylinder movable stand 2 connecting hoses integrated operating platform mobile trolley a six purged with nitrogen to gaseous nitrogen, the residue gas replacement frequency is generally clean and replacement after three times the replaced combustible gas detector to detect whether replacement clean, if you need continuous replacement exceeded until detector measurements show a list of standard equipment: high-pressure nitrogen container frame 1 set, providing a source of nitrogen gas concentration of combustible gas detection 1 set connection hoses integrated operating platform mobile trolley a seven Cylinders parts and safety accessories repair all combinations of parts of the valve, the use of time if it can not meet the requirements of the next inspection time required to update all the new parts, not refurbished safety check valve and replace equipment list: 1 set Angle safety valve check Taiwan test-bed 1 set of eight tightness test using high-pressure nitrogen gas filled, pressure 1.6MPa, dwell time of 15 minutes, use it Apply soap water below cylinders piping and valves leak detection to check whether the level sensor docking elbow where there are leaks in accordance with the GB / T12137 "cylinders tightness test" to check the charging line check valve butt joints where there is a leak check Local level sensor connector sleeve leaks criteria: inspection found no leaks or the formation of bubbles slowly accumulate and the bubble size of less than 10mm, not a violent break; or after a few minutes of small bubbles are tightness test qualified. Equipment list: High-pressure nitrogen container frame 1 set to provide nitrogen gas source nitrogen booster set of connecting hoses leak detection means a comprehensive set of platform mobile trolley a helium leak Taiwan IX cylinders mezzanine vacuum measurement using a dedicated vacuum measurement instrument or device to measure the testing process and the number of measurements in accordance with GB / T18443.2-2010 "vacuum insulation cryogenic device performance test methods - Part 2: vacuum measurement" documentation requirements for measurement of vacuum at room temperature of the bottle is not injected liquid cryogenic equipment list: Laminated vacuum system, one integrated platform mobile trolley a decade, on sandwich vacuum cylinder repair using special vacuum equipment to fill cylinders mezzanine were evacuated to a vacuum degree back to the cylinder factory value equipment list: Laminated vacuum system, one integrated platform mobile trolley 1 XI static evaporation rate test 'test and measure the amount in accordance with GB / T18443.5-2010 "vacuum insulation cryogenic equipment Performance test methods Part V: Static evaporation rate measurement "document requirements' test method using a gas mass flow meter method to test medium using liquid nitrogen criteria: 1. The cylinder day static evaporation rate should be no more than 2 times the specified manufacturing standards qualified indicators index in the following table and not more than 1 qualified qualified indicators Table 1 car with LNG gas cylinder day public static evaporation rate, said the volume of L 50 100 150 200 250 300 350 daily static evaporation rate% 5.4 5.1 5.1 4.8 4.8 4.8 4.5 This standard Twelve developed by the provincial Quality and Technical Supervision, qualified cylinder printing labels tested and cylinder basis having "TSG R0006-2014 cylinders Safety Technology Supervision" requirement in gas cylinders. This inspection stamp printed thirteen, gas Bottle inspection report in accordance with the sample test report issued by this test report, using the unit and testing organizations cylinders each keep a fourteen other test safety precautions welding insulation cylinder 1. The vehicle is loaded medium is liquefied natural gas, the temperature of minus 162 degree, the boiling point of normal inspection process to avoid frostbite 2. The natural gas is a combustible gas, combustion air mixing ratio of 5% to 15%, test site away from the fire, 649 degrees Celsius temperature region of Mars and over.
