Loading and unloading arm (without nitrogen protection device)

Loading and unloading arm without nitrogen protection device: The loading and unloading arm is composed of liquid phase arm, gas phase arm, and booster arm. The steering valve of the unloading arm adopts a special seal to ensure that air does not enter the interior of the steering valve, avoiding the phenomenon of the steering valve freezing and unable to rotate. The loading and unloading arm does not require a nitrogen protection system, reducing equipment investment and the cost of purchasing nitrogen during later operation.

The product is made of stainless steel 316L material and manufactured using a special low-temperature welding process. The key component rotating joint is designed using aerospace technology, completely avoiding the occurrence of leakage caused by welding deformation and sealing surface damage, achieving zero leakage.

Applicable media: liquefied natural gas, liquid oxygen, liquid ammonia, liquid nitrogen, liquid chlorine, epoxy propane, etc.

Nominal diameter: DN32-DN100 Design temperature: -196 ℃~-250 ℃

Design pressure: 0.06MPa-6MPa Pipeline material: 304, 304L, 316L
