            [justin] : What are the requirements for the material of the oxygen pipeline?

            Answer: Oxygen may react with carbon in steel under friction, impact and spark under certain conditions, especially under high pressure. In addition to the requirements shown on the downstream side of the pressure or flow control valve group, a length of stainless steel pipe (GB2270-80) or copper-based alloy pipe with a length greater than 5 times the outer diameter of the pipe and not less than 1.5m should be used; The stainless steel pipe should also be used for the oxygen release pipe section with working pressure greater than 0.1MPa on the downstream side.

            [justin] : Why do small oxygen generators originally use piston expanders, and large oxygen generators use turbo expanders?

            Why do small oxygen generators originally use piston expanders, and large oxygen generators use turbo expanders? ???Answer: The turbo expander has the advantages of large gas flow, high efficiency, no friction parts, stable operation and reliable operation. For large oxygen generators, a full low pressure process is used. Since the pressure drop is small, the unit cooling capacity is small, and the expanded air is sent to the upper tower for rectification, it is desirable that the expander has the highest possible efficiency to reduce the influence of the expansion amount on the rectification

            [justin] : How PSA Oxygen plant work?

            PSA-sorption is the physical process of separating molecules.Pressure Swing Adsorption (PSA) oxygen plant systems product oxygen by separating it from the nitrogen in ordinary air. Air, of course, is 20.9% oxygen and 78% nitrogen, along with a small percentage of inert gases. Within our oxygen plant, a vessel containing a molecular sieve called zeolite is filled with compressed air. The nitrogen molecules are adsorbed by the sieve material while the oxygen molecules drift past and are collected in an oxygen receiver tank attached to the oxygen plant. Pressure is then released from the ve

            [justin] : low pressure process expander

            A: In the air expansion, low pressure process of air separation plant, the expansion of air directly into the tower to participate in distillation. If the amount of expanded air entering the upper column is increased, the average nitrogen purity is reduced and the oxygen extraction rate is lower. Therefore, to ensure the required cooling capacity under the premise of trying to reduce the amount of expansion of air is to improve the extraction rate of oxygen one of the important measures. That is, in the case of a certain amount of processing air, can increase the oxygen production. The higher

            [justin] : What's the warranty for the storage tanks?

            What's the warranty for the storage tanks? Re: Our warranty is one year after shipment. Within one year, we will send broken spare parts at our cost upon request if it is proved to be our production defect. In fact, we rarely receive any spare parts request. If the tanks are maintained properly, they can be used for 15-20 years.

            [justin] : What is your production standard? Can you manufacture your products under ASME standard?

            Our products are designed, manufactured and tested as per reference standards of GB150, Safety technology supervision regulations of pressure vessels and some other reference Chinese standards. Our company has obtained the A2 and C2, C3 Pressure Vessel Fabrication Certifcates ,Grade GC1 Pressure Pipe& Vessel Construction Certifcates, ISO9001 Quality Certificate, ASME Certificate and U Stamp. So, if you ask for ASME stamp, we are able to manufacture your products under ASME standard.

            [justin] : We would like to buy a storage tank. Re: Before making quotation to you, please kindly specify the following information

            [justin] : uses-and-features-of-acetylene

            1Acetylene is the best and most versatile fuel gas for welding, straightening, bending, forming, hardening or tempering. It is the hottest flame temperature when compared to Mapp gas, propylene and propane and natural gas (2,910°C, 2,895°C, 2,800°C and 2,780°C respectively). 2.Acetylene is used as a fuel gas for oxy-acetylene welding, cutting, general localised heating, flame hardening, flame cleaning to remove rust from steel, spalling concrete and other processes requiring a high temperature flame (3,160°C when combusted in oxygen). 3.Specially purified instrument grade acetylene
