Product Brief
Industrial grade oxygen is compressed oxygen supplied as industrial raw oxygen O2, widely adopted in metal fabrication, combustion enhancement and chemical oxidation workflows. This industrial O2 gas is separated from air through cryogenic distillation, and it is filled into pressure vessels after filtration and quality inspection. Every 40L oxygen in steel cylinder undergoes hydrostatic test and leak check before dispatch to meet international hazardous cargo transport standards.

Product Details
This 99.5% purity oxygen gas maintains consistent oxygen concentration with limited inert impurities, which delivers steady flame temperature during oxy-fuel operations. Stable combustion performance helps fabricators achieve cleaner cutting edges and reduce slag adhesion on steel workpieces, lowering secondary grinding workload and speeding up workshop turnaround. The 40L seamless steel cylinder oxygen adopts thick seamless steel structure, which offers strong pressure resistance and long service life for repeated refilling cycles. Operators can move, connect and store these cylinders conveniently in small and medium fabrication workshops without heavy fixed piping systems. Each cylinder is fitted with a dedicated oxygen service valve and protective cap, preventing oil contamination and accidental valve damage during transit and on-site handling. All cylinder marking and hazard labels follow GHS and IMDG requirements, which streamlines customs clearance for cross-border shipments. We provide batch COA and MSDS for every consignment. Buyers can complete incoming inspection and site safety audit smoothly. Our supply team accepts scheduled orders and flexible delivery to match your workshop consumption rhythm.
