The gas cylinder production line requires equipment
What equipment is needed for the steel seamless high-pressure gas cylinder production line (34CrMo4/37Mn, the most common type)?
1. Raw material cutting and heating section
Plasma pipe cutting machine: Fixed-length cutting of steel pipes / round steel
Medium-frequency induction heating furnace: Uniform heating of steel pipes at 1100~1250℃, with temperature control and data recording
2. Core forming section (key equipment for the entire line)
CNC strong press machine for gas cylinder pressing
Bottom press machine: Sealing the bottom of the gas cylinder to ensure uniform wall thickness
Milling bottom machine: Removing burrs and oxide scales from the bottom
Gas cylinder bottom airtight machine: Checking the bottom airtightness
3. Heat treatment section (special equipment mandatory for special equipment)
Continuous roller bottom-type quenching furnace (temperature control ±15℃, with data storage)
Quenching cooling water tank / high-molecular quenching pool
Continuous tempering furnace (tempering treatment, quenching + tempering to enhance strength and toughness)
In-furnace temperature recorder, hardness inspection tool
4. Bottle mouth precision machining section
CNC bottle mouth special lathe: Turning the outer circle, processing standard gas cylinder threads, chamfers
Thread processing: Processing the high-pressure sealing threads at the bottle mouth
Bottle mouth deburring and cleaning machine
5. Inner and outer surface cleaning equipment
Pass-through shot blasting machine for gas cylinder outer wall: Removing heat treatment oxide scale, uniform roughness, improving coating adhesion
Sandblasting / high-pressure water cleaning machine for gas cylinder inner wall: Cleaning the inner wall oxide and impurities
Internal drying furnace: Thorough drying after inner wall cleaning to prevent internal rusting
Internal phosphating / passivation tank (corrosion medium gas cylinders selected)
6. Non-destructive testing (100% full inspection, mandatory for certification)
Ultrasonic flaw detector UT: Detecting the wall thickness of the cylinder body, internal cracks, delamination
X-ray real-time imaging flaw detector RT: Inspection of bottle mouth, bottom welds / pressing defects
Magnetic particle flaw detector MT: Screening surface micro-cracks, fatigue cracks
Automatic thickness measuring instrument, internal inspection scope (visual inspection of inner wall defects)
7. Pressure safety test section (full inspection at factory)
External measurement water pressure test machine: Water pressure strength test (1.5 times nominal pressure)
Air tightness test machine (dry air / nitrogen): Immersion-type air tightness detection
Explosion test bench (random inspection equipment, must be done for each batch)
Fatigue cycle test machine (CNG / hydrogen cylinders selected)
Automatic bottle valve loading machine, valve calibration table
8. Identification and painting section
Gas cylinder steel stamping marking machine (permanent identification, steel grade, water pressure date, standard)
Electrostatic powder spraying line / spray painting assembly line: Pre-treatment, drying, topcoat
Drying and curing furnace, automatic conveying roller
9. Laboratory physical and chemical testing equipment (mandatory for factory certification)
Universal material testing machine, low-temperature impact testing machine, Brinell / Rockwell hardness tester
Spectroscopy analyzer (chemical composition detection of raw materials), metallographic microscope
Dimension calipers, wall thickness gauge, roughness gauge
10. Auxiliary supporting equipment roller conveyor line, crane, air compressor, explosion-proof dust removal system, wastewater treatment equipment, finished product storage and transportation
