What should we pay heed to when we are about to buy ERW steel pipes? Of course, quality is the first factor we should focus on, then comes the price we should pay attention to, but there is also another factor we should pay attention to-- lifespan of the pipe.

Long service life would be an important factor for a kind of ERW steel pipe when it applied in engineering project as this means saving money to fix it and change it.

Steel pipe, used in water, oil and gas transportation, is necessary to have a relative long lifespan.

As there are advantages for long lifespan: first of all, we should know that it would cost human resource as well as cost if we have to change it often. What’s more, it would influence the basic usage for customers if we change it often which would damage the whole process for customers sometimes.

Plastic or wood pipes would not so strong for the vehicles’ weight when we use them underground. So that steel pipe, with its hardness, is the top choice for this situation. Of course, because of the external corrosion and internal abrasion. The service life of steel pipes would be increased by the usage of proper coating and cathodic protection. With attention to coatings and cathodic protection, the service life of steel pipe can be extended indefinitely.
