Product Application

Galvanized steel pipe processing is special, generally using carbon structural steel, low alloy structural steel to make, and its output is large, can also be customized according to different needs, the performance is very good.

Architectural Applications

In most cases, the construction of pipelines is to use seamless steel pipe, especially underground pipeline transportation, in order to ensure the sealing effect and strength, then generally will use such steel pipe, long-term underground use is also guaranteed. Or is the extraction of groundwater, boiler delivery of hot water, are also to use such pipes.

Machining of machinery

There are a lot of mechanical processing is to use steel, in order to ensure the processing performance, in line with the application of most accessories, can also be used in seamless steel pipe, such as the processing of bearing sleeve, or mechanical processing accessories, can be used in such steel pipe.

Electrical Applications

Now gas transmission, as well as water power generation fluid pipeline, can also use such steel pipe. Stable performance, but also can ensure a long service life.

There are some special applications that need to use special seamless steel pipes, so we still need to select steel pipes according to our actual situation. We can also contact the manufacturer directly to choose and buy, in order to ensure that the steel pipe meets our use needs.
