In order to increase the service life of pipeline, pipeline anti-corrosion construction has become an indispensable link in the pipeline production process; With the continuous progress and production of manufacturers, a variety of anti-corrosion spiral steel pipes are on the market, so how can ...

Pipeline anticorrosion plays a very important role in the construction of a project. It plays a key role in the quality of the whole project construction. Through the anti-corrosion pipe service life can also be achieved 50 years, so through strict design, reasonable use, then 3PE seamless anti-...

Carbon steel seamless elbow as an indispensable part of our lives, it needs to be regularly maintained, then we will analyze what carbon steel seamless elbow needs to pay attention to, what aspects can not be touched, let's take a look at it Improve the corrosion resistance of carbon steel se...

Prefabricated direct buried insulation pipe has become a more complete technical application in other developed countries, the prefabricated direct buried insulation pipe is composed of a steel pipe for transporting materials, a high-density polyethylene outer sleeve with high density, and a rig...

There are many kinds of thick wall spiral steel pipes processed by manufacturers, and steel pipe damage will inevitably occur in the loading and unloading process. The actual precautions are as follows 1, the thick wall spiral steel pipe packaging should be able to avoid falling and damage in...

The spiral steel pipe is durable and practical, has become the key signal of engineering construction, the pipe maintenance media transport is one of the key materials, spiral steel pipe is the steel oil pipeline, gas pipeline, water supply pipe, heating pipe outer wall anticorrosion constructio...

Seamless stamping elbow after welding permeability is more improved, too easy to crack, if it is the same type of stamping elbow welding, the first preheating of the eye after welding is suitable for temperature above, welding parts can not be post-welding heat treatment, therefore, in order to ...

We all know that the steel pipe can not be exposed to the sun, it will affect the use of the steel pipe, it will affect the service cycle of the steel pipe, so the storage of the steel pipe and understand the characteristics of the performance is still very important, today the anti-corrosion in...

The specific method of checking the high-frequency straight seam welded pipe is that such non-fusion is generally reflected in the failure of the pressing process, the crack of the steel pipe during the hydraulic test, or the crack of the welding gap when the steel pipe is straightened, which is...

The spiral steel pipe is durable and practical, and has become the key signal of engineering construction, but the maintenance medium transported is one of the key materials. The spiral steel pipe is the outer wall anticorrosion construction of the steel oil pipeline, gas pipeline, water supply ...

From the surface of the spiral steel pipe to see the processing technology of the spiral steel pipe is not exquisite, generally speaking, good pipe manufacturers in the processing level will be careful, there will not be some friction problems, and on the other hand to knock the -+metal spiral s...

Elbow is to connect two pipes with the same outer diameter to each other, so as to change the pipe orientation effect is the main function of elbow, if the installation of plastic elbow is not standard, the medium in the pipeline will leak out, harm the whole production process, and lead to the ...
