Methods of Storing Austenitic Stainless Steel Pipe

Aug. 29, 2019

If the Austenitic Stainless Steel Pipe is stored for a long time in the open air, problems such as rust pits, wall thickness reduction after rust, warpage of the anti-corrosion layer, aging of the anti-corrosion layer, etc. may occur, which may cause the steel pipe to be degraded, discarded or re-processed. Waste of resources. Mainly the steel pipe body is uncovered, the cover protection is not ideal, there is no support, the part is the problem of too many stacking layers, and most coastal areas are maritime climate, with large annual rainfall, high air humidity, and steel pipe contact with a steel pipe. Caused by water accumulation in the area. Nickel Alloy Pipe Factory recommends that the protection method be:

Austenitic Stainless Steel Pipe

Austenitic Stainless Steel Pipe

1. Whether it is a bare tube or an anti-corrosion tube, if it needs to be stored for a long time, it should be protected by opaque covering when starting storage, to avoid corrosion of the steel tube and aging and warping of the anti-corrosion layer.

2. The cover should be strong and durable to prevent prolonged exposure to sunlight and rot.

3. When the steel pipe is covered, the surface of the steel pipe should be ventilated to avoid the water vapor being difficult to volatilize and collect on the surface.

4. When the steel pipe is stored, it should have the support and a certain distance from the ground to ensure the ventilation of the steel pipe.

5. After the Seamless Stainless Steel Tube is stored and stored, the pipe end protector should be removed to prevent moisture from collecting at the contact surface of the pipe end protector and the steel pipe and it is difficult to volatilize.

6. When storing steel pipes, attention should be paid to the number of layers of steel pipes stacked to avoid local stress on the pipe ends caused by the excessive number of layers, thus causing radial plastic deformation of the steel pipes and damage of the anti-corrosion layer.

7. Avoid contact with pollutant oil, copper, etc. when storing steel pipes.
