On the production side, in the past decade, with the rapid expansion in the field of application, manufacturers of welded steel pipe has increased a lot. Comprehensive production and processing capacity also has a large development.
Petrochemical industry has a complicated medium in its operating environment, such as there exists solid, gas and liquid which is causticity, wearability, inflammable, explosive and toxic and different kinds of chloride, sulfide and salts. So in petrochemical industry, it demands the welded steel pipe has a strong corrosion resistance.
In recent years, the situation of fresh water resources in China is not optimistic. In more than 600 cities in the country, there are more than 400 cities which are short of water. But in China, we have nearly 20000 km of coastline and rich water resources. In response to the situation of fresh water supply, we need more seawater desalination equipments. In this case, we need more welded steel pipe.
In other industries, such as car industry, electronic instrument industry, water supply industry and many other industries, we also need a huge demand of welded steel pipe. And there are many industrial sectors which we can’t calculate how much of this material we will need. So what we can be sure is that this is a huge potential market.
