here we introduce a simple method to test the purity of C2H2 gas on site, we dip the silver nitrate solution onto the test paper, then put the test paper under the gas sampler, if the test paper colour doesn't change, the purity of C2H2 gas can reach at least about 98%, this purity is enough to be used in industrial application.

the acetylene gas is compressed by the piston compressor, which is piped to the molecular sieve high pressure dryer, the dryer can remove the moisture, then the dry acetylene gas is piped to the cylinder for filling

acetylene gas generator is an important equipment during the acetylene gas producting, the calcium carbide and water will react in the generator, and then the acetyhlene gas will be piped to the next equipment.

we can supply various mechanical seals, such as metal bellows seal, cryogenic metal bellows seal, CrO coated stainless steel ring, wave spring and rubber ring, mechanical seal supporting system, fluid reservoir, hand refill pump, heat exchanger, cyclone dust separator, dry gas face, cartridge mechanical seal and long sleeve metal bellows seal, etc..

The function of this equipment is based on the principle of natural balance of adjacent adsorbent loads. In the drying stage, the adsorbent adsorbs water from the gas with high pressure flowing through the GZ-120/25 Molecular sieve high pressure acetylene gas dryer manual adsorber. During regeneration, a small amount of depressurized dry gas is replayed and regenerated through the adsorbent adsorbing water. Use the adsorption released by the gas in the drying process to heat the regeneration gas with reduced temperature after decompression, so as to improve the regeneration effect and reduce the regeneration consumption.

our small oxygen gas diaphragm compressor parameters for GD-85/35-300 are as below: inlet pressure 35bar, outlet pressure 300bar, flow 85Nm3/h and medium oxygen gas

small type Z diaphragm compressor is mainly used for laboratory, collecting various gases, and some of compressor are also installed in the container for compressing gases during movement.

Diaphragm compressors have multiple advantages, making them very popular in specific application fields. Here are some of the main advantages of diaphragm compressors: high gas purity, leakage prevention, quiet operation, low maintenance, high energy efficiency, high reliability and wear free compression.

acetylene gas is used with oxygen gas for cutting, in order to produce acetylene gas, our factory especially a set of simple production line to produce about98% purity acetylene gas to satify our customers' requirements

Corrosion resistance: The CrO coating provides an additional corrosion-resistant layer, which helps protect stainless steel materials from chemical corrosion, especially when used in harsh chemical environments. Wear resistance: The coating may enhance the wear resistance of the sealing ring, which helps to extend the service life of the mechanical seal and reduce the frequency of maintenance and replacement. Reduce friction coefficient: Coatings may help reduce friction between the sealing ring and the corresponding sealing surface, which can reduce energy loss and improve mechanical efficiency. Good sealing performance: The CrO coated sealing ring is designed to achieve a good sealing effect, preventing the leakage of liquids or gases, which is crucial in pumps, valves, and other rotating equipment. High temperature endurance: The coating may enhance the performance of the sealing ring under high-temperature working conditions, which is particularly important for mechanical seals used in high-temperature environments. Material compatibility: CrO coating may improve compatibility with different process fluids, enabling it to resist corrosion from various chemicals, including acids, bases, and solvents. Reduce maintenance: Coatings may reduce the maintenance requirements for sealing rings, as coatings can reduce wear and corrosion, thereby reducing the need for regular inspections and maintenance. Improving system reliability: By reducing leakage and enhancing sealing performance, CrO coated sealing rings help improve the reliability and safety of the entire system. Environmentally friendly: The use of CrO coating may reduce environmental risks caused by seal failure, as it reduces the leakage of chemicals into the environment.
