Key Product Specifications

Purity Grade & Impurity Control

We supply full-gradient propane gas strictly complying with GB/T 24460-2009 and GB/T 14602-2014 national standards, with precise impurity screening and batch-by-batch testing to meet industrial fuel, chemical synthesis and laboratory testing scenarios:

1. Industrial Fuel Grade (≥95.0%)

Suitable for industrial heating, boiler fuel, metal cutting and general LPG applications. Strictly control common impurities such as ethane, butane, water and sulfur compounds, with stable combustion performance and high calorific value, meeting the basic energy supply needs of industrial production.

2. High Purity Grade (99.5%-99.9%)

Applied for precision metal cutting, brazing, chemical synthesis and conventional laboratory experiments. Controlled impurities: Total unsaturated hydrocarbons ≤100ppm, Moisture ≤10ppm, Sulfur ≤1ppm, ensuring clean combustion and no contamination to processed materials.

3. Ultra-High Purity Grade (99.99%-99.999%)

Dedicated for electronic industry, semiconductor manufacturing, special material synthesis and precision instrument calibration. After deep purification and adsorption treatment, trace impurities such as moisture, heavy hydrocarbons and heteroatomic compounds are controlled below 0.1ppm. It features ultra-high purity and stable chemical properties, fully adapting to high-precision industrial and scientific research scenarios.

Physical & Chemical Properties

Propane (C₃H₈) is the third member of the alkane series with stable chemical properties under normal temperature and pressure. It is colorless, odorless, heavier than air, and slightly soluble in water, easily soluble in organic solvents such as ethanol and ether.

Propane has excellent combustion performance with high calorific value (50.4 MJ/kg) and clean combustion products. It is chemically inert at room temperature and does not react with common strong acids, strong alkalis and oxidants. Under high temperature, high pressure or catalytic conditions, it can undergo oxidation, substitution and pyrolysis reactions, which is an important raw material for organic chemical synthesis. It has a flammable explosion limit of 2.1%~9.5% in air, requiring standardized storage and transportation.

Packaging & Transportation Solution

We provide standardized global packaging solutions for both compressed and liquefied propane gas, supporting small-batch trial orders and large-scale bulk supply, adapting to regional import standards worldwide:

• Standard Compressed Steel Cylinders: 4L, 10L, 40L, 47L seamless steel cylinders with professional propane special valves. DOT and ISO certified cylinders are available for European, American and Southeast Asian markets, fully compliant with international flammable gas transportation norms.

• Cylinder Bundle Packaging: 6-pack and 12-pack cylinder bundles are provided for centralized storage and transportation, which is convenient for factory continuous gas supply and large-scale industrial supporting use.

• Bulk Transportation: Equipped with dedicated flammable gas tank trucks and ISO standard tank containers for bulk delivery, realizing stable and low-cost gas supply for large industrial parks.

• Industrial Liquefied Propane Cylinders: 50KG YSP-50 standard liquefied propane cylinders (as shown in the picture), with special two-phase valves (liquid phase + gas phase) for industrial use. All cylinders are inspected and certified by national authorities, with insurance coverage. Suitable for large-scale industrial heating, metal processing and chemical production.

• Customized Service: Support personalized customization of filling pressure, gas purity and valve interface models to match different customer equipment and production needs.

Main Applications

Propane gas is widely used in energy supply, metal processing, chemical industry and scientific research fields, with strong industrial versatility:

1. Industrial Energy Fuel: Used as clean burning fuel for industrial boilers, heating equipment, metal cutting and welding processes, with high calorific value and low pollution emissions. 50KG liquefied cylinders are the most cost-effective solution for continuous industrial use.

2. Chemical Raw Material: Applied for the synthesis of propylene, ethylene, propylene oxide and other chemical products, serving the petrochemical and fine chemical industries.

3. Refrigeration Industry: Used as a refrigerant in commercial refrigeration systems and air conditioning units, with excellent thermodynamic properties.

4. Aerosol Propellant: Applied as a propellant in aerosol products such as spray paints, insecticides and personal care products.

5. Laboratory & Detection Industry: Used as standard calibration gas for gas chromatography, environmental monitoring and industrial instrument verification.

6. New Energy & Scientific Research: Applied for fuel cell research, catalytic reaction experiments and combustion dynamics testing, supporting university and research institute R&D projects.

Safety & Export Compliance

All propane gas products comply with UN1978 flammable gas transportation standards and relevant national specifications. Propane is a flammable and explosive gas, which is heavier than air and may accumulate in low-lying areas. For liquefied propane cylinders, they must be stored and used in an upright position to prevent liquid leakage. Keep away from open fire and high-temperature heat sources. We provide complete export documents including MSDS safety data sheet, batch COA quality certificate and origin certification, and provide professional safety operation guidance to ensure safe use and smooth global customs clearance.
