How to protect your structural steel tube from damages in use?

In the iron and steel industry, welded steel pipe is one common type of steel products widely used in a variety of applications today. It is believed that welded steel pipe is available in wide ranges of sizes and properties of the steel. As we have talked more about welded pipe applications around us, today we would like to give further information about how to protect your welded steel pipe from damages in applications.

There are several considerations as below that should not be overlooked by designers of buried steel pipe:
a) Quality assurance of welds. Longitudinal stress in the pipe could possibly be limited by strength of welds. Protective coatings must be replaced over field welds.
b) Soil conditions. The buried steel pipe performs structurally as part of a pipes oil interaction system. The importance of the soil must not be overlooked. Soil quality, placement and compaction are part of the design of all buried flexible pipe. Possibility of soil movement should be considered.

Today, welded steel pipe is widely used in the piping systems to convey fluids over significant distances. Hot dipped galvanized steel pipe is one ordinary type of pipes used for pipelines in the world. As to some buried pipelines, it is a fact that steel is prone to corrosion in use as the time goes on. Therefore, it seems very necessary for you to try to take measures to extend their service life. Generally, there are three main repair scenarios considered such as pipe subject to external metal loss (caused by corrosion or mechanical damage), pipe subject to internal metal loss (caused by corrosion, erosion or erosion/corrosion), and piping components that are leaking. In addition to these main repair scenarios, the extent of the deterioration or damage (i.e. localised or extensive) will also be considered when choosing the repair methods and repair components.

As a rule, based on different pipework failures of pipes, there are the specific methods to used for maintenance of pipes. Galvanized coating for some cold rolled steel pipes is a very common method used to protect steel products from corrosion. Furthermore, a couple of buried flexible pipes have a series of requirements including strength, ease of installation, high flow capacity, leak resistance, long service life, reliability and versatility, and economy.
