Experience a Symphony of Colors: Customizable Gas Cylinders in Varied Hues
Authentic Glimpse: Real Shot Image of Our Gas Filling Factory StorageExplore Our Assortment: Valves, Caps, Neck Collars, and Trolleys for Your Consideration1,Overall Punching Method:Experience the precision of our advanced cylinder production: the journey begins with billet sawing and cutting, followed by precise induction heating. Reverse extrusion punching ensures the perfect form, while drawing, edge trimming, and closing deliver a flawless finish. A critical heat treatment process enhances durability, complemented by external sandblasting for a pristine surface. Mouth thread processing and internal sandblasting (or phosphating) secure the interior's integrity, leading up to rigorous water pressure testing. Valve installation and an air-tightness test guarantee safety, followed by a sleek plastic spraying and careful drying. Our meticulous inspection ensures only the best for storage.
2, Steel Pipe Spinning Method:
Our innovative steel pipe spinning method starts with precision sawing and cutting, progressing to induction heating that primes the material for perfection. A seamless spinning bottom sealing and meticulous milling of the inner bottom set the stage for quality. Further induction heating readies the pipe for expert end closing, followed by a thorough heat treatment. Sandblasting preps the surface as we proceed to mouth thread processing and internal sandblasting (or phosphating), ensuring comprehensive conditioning. The process is validated by a robust water pressure test, precise valve installation, and stringent airtightness testing. The final touch is a professional plastic spraying and drying, culminating in a detailed inspection prior to storage.
