  DIN 17175 seamless carbon Black steel pipe looks black from appearance. The dark color comes from the iron-oxide formed on its surface during manufacturing. The black pipe is a light coating and provides only the barest protection. Black pipe will rust outdoors.

  1. Reasons why DIN 17175 seamless carbon black steel pipes rust

  The main reasons why DIN 17175 seamless carbon black steel pipe rusts are as follows:

  (1) Effect of chloride ions

  Chloride ions will accelerate the corrosion of stainless steel. The higher the chloride ion content in the water, the faster the steel pipe will corrode.

  (2) Influence of environmental factors

  When black steel pipes are used or stored in areas such as seaside, harbors, and islands, they are susceptible to corrosion by seawater and salt spray, leading to rust. In addition, acidic environments and normal temperature and humid environments will also accelerate the corrosion of steel pipes, causing them to rust quickly.

  (3) Material issues

  If the quality of the black steel pipe is poor, such as using substandard raw materials or improper handling during the welding process, it may cause the black steel pipe to rust.

  (4) Human factors

  During transportation, if you do not pay attention to the maintenance of the pipeline, the pipeline may be contaminated by contaminating and corrosive chemical products, or damaged by sharp objects, which will cause the black steel pipe to rust.

  If dealers do not pay attention to the maintenance of pipelines during transportation, or use corrosive chemical products to clean stainless steel in highly polluted areas (such as seashores, chemical plants, brick factories, electroplating and pickling plants, water plants, sewage treatment plants, etc.), this will It may also cause DIN 17175 seamless carbon black steel pipes to rust.
