(1) what is the local corrosion: sometimes pipeline corrosion effect only occurred in the steel tube of a local scope, which other parts basically did not happen, also have another kind of circumstance is a portion of the steel tube of the corrosion speed than other parts of the corrosion speed, showed traces of local corrosion damage.
(2) generally greater danger of local corrosion situation is what kind of situation: a. b. hole corrosion stress corrosion cracking c. d. intergranular corrosion crevice corrosion e. galvanic corrosion f. g. hydrogen corrosion, selective corrosion, cavitation corrosion, etc
(3) corrosion situation can be divided into several categories according to the environment: steel pipe are likely to occur in a variety of environment corrosion phenomenon, then according to the corrosion environment can be divided into: chemical corrosion medium, atmospheric corrosion, high temperature corrosion, sea water corrosion, soil corrosion.
(4) how to determine the degree of corrosion, pipeline after corrosion, its exterior shape, weight, dimensions, mechanical strength, and other changes in your organization, can according to these changes in performance to determine the degree of corrosion of metal, and then according to these data to pipeline steel pipe anticorrosion heat preservation.
If you have any questions about corrosion coating pipe,pls contact me in the first time.
Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.
Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.
The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
