1. Storage environment requirements

1. Keep dry and ventilated

• Stainless steel pipes should be stored in indoor dry environment to avoid direct contact between rainwater and moisture.

• The warehouse humidity is recommended to be controlled below 60%, and a dehumidifier or desiccant can be used if necessary.

• If it is required to store it openly, it must be tightly covered with a rainproof cloth and raised to avoid moisture erosion on the ground.

2. Stay away from corrosive substances

• Avoid storing corrosive chemicals such as acids, alkalis, and salts to prevent electrochemical reactions.

• It is prohibited to contact metals of different materials such as carbon steel pipes and copper pipes to avoid galvanic corrosion.

3. Temperature control

• Extremely high or low temperatures may affect the performance of stainless steel, and the storage temperature is recommended to be between -10℃~50℃.

• Avoid direct sunlight, long-term exposure to the sun may cause oxidation and discoloration on the surface.

2. Stacking methods and protective measures

1. Reasonable lifting and isolation

• Stainless steel pipes should be stored off the ground and isolated with wooden pallets or rubber pads to prevent moisture erosion on the ground.

• When stacking multiple layers, each layer is separated by an anti-slip pad or wooden strip to avoid sliding friction of the pipe.

2. Avoid mechanical damage

• The stacking height should not be too high (usually ≤1.5 meters) to prevent the underlying pipe from being compressed and deformed.

• Stainless steel pipes of different specifications (diameter, wall thickness) should be stored in a classified manner to avoid collision damage caused by mixed storage.

3. Protect the pipe mouth and surface

• The pipe opening can be sealed with plastic cover or tape to prevent dust and foreign objects from entering.

• If there is a protective film (such as PE film) on the surface, it should be retained before installation to avoid scratches.

3. Regular inspection and maintenance

1. regular random inspections: Check the inventory pipes every month for rust spots, deformation or damaged packaging, and deal with problems in a timely manner.

2. First-in, first-out (FIFO): Use it in the order of entry into the warehouse to avoid aging caused by long-term backlogs.

3. Cleaning and Maintenance: If you find slight rust, you can use stainless steel special cleaner + soft cloth to wipe it. It is prohibited to use steel wiping balls and other hard objects to scratch.

IV. Measures for special circumstances

• Storage in coastal areas: The air has high salt content, it is recommended to strengthen moisture-proof measures, and choose 316L and other salt spray-resistant stainless steel pipes.

• Winter low temperature environment: Avoid severity and heat, and gently hold it during transportation to prevent brittle fracture.
