Petroleum industry in our country's industry occupies a very important position, because by now has become the largest fuel demand in our country, whether it's oil itself, or a by-product of oil in the refining process, produces high economic efficiency, reduce the pressure on scarce raw materials in China. So the importance of the oil industry can be seen from here.

In the oil industry involves many complex industry, including the establishment of the industrial offshore drilling rig after a very long time, but is not very convenient to use and often require large-scale maintenance, is in order to improve the service life of drilling platform, extend the period of scrap.

In addition to the large industrial equipment, some small parts is also very important. The hollow pipe, for example, although we are not often heard about this part, but the importance of this part is very high. A high quality of the hollow pipe can improve the efficiency of oil production, reduce the waste when extracted crude oil, for our country's oil industry is more efficient, good stress relief resources shortage.

So when selecting a hollow pipe we will choose the customer evaluation is high, the manufacturer of advanced technology. How can we tell which factory is that we need high quality manufacturers? We when selecting a manufacturer, in addition to the reference rendering of manufacturer, factory sales record survey, see if manufacturer sales record is bad review. The most important still is the need for field trips, and only after on-the-spot investigation how to guide the authenticity of propaganda, avoid fraud and false advertising happened in our body.
