A glimpse into our Gas Filling Factory: Authentic storage images showcasing the robust facility and meticulous processes behind our high-quality oxygen supply.Discover a selection of valves, caps, neck collars, and trolleys offered for your consideration and choice.1,Overall Punching Method:Begin with billet sawing and cutting, followed by induction heating. Next, reverse extrusion punching and drawing techniques are employed to form the structure. Proceed with edge trimming and closing, then refine strength and durability through heat treatment. For a pristine exterior, apply external sandblasting. Mouth thread processing ensures compatibility, and internal sandblasting or phosphating optimizes the interior. Rigorous water pressure testing guarantees integrity, and precise valve installation is followed by an air tightness check. A sleek finish is achieved with plastic spraying and drying. Finally, conduct a thorough inspection before storage, ensuring each cylinder is ready for use.
2, Steel Pipe Spinning Method:
Begin with sawing and cutting the steel pipe, then apply induction heating for malleability. Spinning bottom sealing is next, followed by milling the inner bottom. Another round of induction heating prepares for spinning end closing. Heat treatment solidifies the structure, and sandblasting perfects the appearance. Mouth thread processing is meticulously done, and internal sandblasting or phosphating enhances the pipe's interior. Water pressure testing ensures robustness, followed by precise valve installation. An airtightness test is crucial before the sleek plastic spraying and drying finish. A final inspection ensures impeccable quality before storage.
Carefully crafted wooden pallets are used, ensuring secure transportation and stability during transit, while bulk loading maximizes efficiency and reduces handling time. Durable and protective cartons are employed to safeguard contents, offering a reliable solution for smaller shipments.
