1. Company Profile
Shanghai Fengxian Equipment Vessel Factory was founded in 1982, and specializes in designing and manufacturing all kinds of pressure vessels. We have a high profile in the industry. And in 1998, we registered the brand of “Shen Jiang”. Our pressure vessels are widely used in petroleum, chemical, electronic, automotive, power generation, mining, pharmaceutical and other industries. Look forward to the cooperation with you in the increasingly powerful of our company.


2.  Overview


Gas tank media for the oxygen, colorless and tasteless, non-toxic and non-explosive gas. In the standard case, the oxygen density is 1.429g / L, slightly larger than the air (air density is 1.293g / L). It is not easy to dissolve in water, 1L liters can only dissolve about 30mL oxygen.


3. Safety Requirements


(1) In the site and layout, must be away from fire, metallurgical furnace, high temperature source, and with the gas, liquid storage and pipeline isolation. And railways, highways, buildings, overhead power lines to maintain a certain safe distance, to meet the "building design fire safety requirements" requirements.
(2) Oxygen tank design, materials, pressure performance must comply with the relevant provisions of the state.
(3) Welding should be strictly checked. The pressure vessel welding training assessment to obtain the operating qualification of the welder to welding, the general use of x-shaped groove double-sided welding, to be penetration, no inclusions, cracks, craters, bubbles, bite and other defects. Before welding to warm up, the electrode to dry, weld repair can not be more than twice. Weld all use ultrasonic flaw detector (internal and external surface inspection), and use magnetic particle detector to check the surface, with x-ray film inspection, the greater the better the proportion of checks. Three types of containers to 100% with x-ray film inspection.
(4) Oxygen tank to strict degreasing degreasing. The general use of sandblasting process, the metal surface to light up, both rust and degreasing. To prevent oxidation, the inner wall to be coated with a layer of zinc powder, water glass-based modulation of inorganic zinc-rich paint. Before the tank can be put into the hole, the internal debris must be cleaned and degreased with carbon tetrachloride.
(5) Strength test & air tightness test should be done.


4. Testing


1) strength test. Oxygen tank installation is completed, must be water pressure test, check the construction quality, to ensure its safety and reliability. The test pressure is 1.25 times the design maximum working pressure. Under the test pressure should be observed for 10-30 minutes. No drop in pressure, the appearance of no deformation, no water, no rupture were qualified. Test water must be clean and free of grease. After the end of the strength test, the water should be blown dry so as to avoid corrosion. The strength test can also be done with the warm water overload pressure test to eliminate the welding residual stress. Strength test can also be done with nitrogen or without Shan air. The test pressure is 1.15 times the design maximum working pressure.


2) air tightness test. After the strength test, with air or oil-free air at the design of the maximum working pressure for air tightness test. At the same time with a fat-free soapy water leaks to check the tightness of the tank. 24 hour leak rate is less than 5% for qualified. After the airtight test is passed, the tank should be blown with oil-free air or nitrogen. Wipe with a white cloth, do not see water, impurities so far. Or from the human hole into the people after cleaning clean with carbon tetrachloride degreasing.


5. Function


a. Energy storage (for emergency needs)

b. Stable pressure

c. Ease pulse impact on gas equipment

d. To precipitate water, grease & dust in the air

e. Improve the continuity and stability of the equipment for the gas output

f. Reduce the frequent start of the compressor, extend its life


6. Production Process


1. Lofting, marking-off & cutting. 2. Manufacturing & welding a. Make holes b. Crimping plate c. Spheronization d. Welding e. Install f. Circumferential welding 3. Surface treatment a. For Carbon Steel (1) Sand blasting (2) Primer (for 2 times) (3) Finishing coat b. For Stainless steel (1) Sand blasting OR (2) Polishing
