Why should steel pipe be anticorrosive

Jan 04,2023

The treatment quality of the main base of the steel pipe directly affects the adhesion quality and anti-corrosion effect of the anti-corrosion layer. At present, the commonly used methods for basic treatment include jet rust removal, tool rust removal, chemical rust removal and flame rust removal.

Understanding the properties of steel pipe can be a better choice

Sep 13,2022

1. From the appearance of spiral steel pipe. In appearance, it is necessary to carefully discuss the welding, see whether there are shortcomings in appearance, whether there is a lack of standards, these can probably be seen from the naked eye, although to be careful and both sides of the theory, take out the basis of the example of the sample, gauge and magnifying glass to inspect. Due to the shortcomings of the welding on the outside, it means that there are probably defects in the spiral steel pipe. Even the appearance of time is not done, and the time inside is difficult to ensure.

What is the classification of steel pipe

Aug 20,2022

Casing: Pipe inserted from the surface into the well to serve as a lining and connected by a collar. The main material is J55, N80, P110 and other steel grade, as well as hydrogen sulfide corrosion resistant C90, T95 and other steel grade. Its low steel grade (J55, N80) can be welded steel pipe.

Development of steel structure and application of steel pipe

Jul 27,2022

The excellent structural performance of the circular tube shape under compression, torsion and multi-direction bending has been fully fulfilled. The reed in the wind, the bamboo in the rain, and the thigh bone that supports the weight of the human body are all round tubes. Perhaps people get inspiration from this, the excellent structural performance of the round pipe and a very attractive architectural shape combined to form the steel pipe structure. In recent years, the applications of circular tube structure include building, bridge, dam, offshore platform structure and tower mast.
