Application of seamless steel pipe is quite extensive, in order to understand the application of seamless steel pipe, we need to clearly know various advantages and disadvantages of seamless steel pipe, only know that we can know more understand we need that type.
(1) seamless steel pipe
General seamless steel tube is made of ordinary carbon steel, quality carbon steel, low alloy steel or alloy structure steel rolling. More varieties of different specifications, high strength, process piping is the most commonly used as a pipe, widely used in pressure pipeline 1.6Mpa below. Such as heat pipe, cooling pipe, compressed air pipe, oxygen pipeline, acetylene piping, and in addition to the strong corrosive medium, such as chemical piping.

(2) stainless steel seamless steel pipe
Stainless steel seamless steel pipe with chromium nickel stainless steel, there are two kinds of hot rolling and cold rolling (Leng Ba) tube, is characterized by strong acid resistance, corrosion resistance, but expensive, mainly used for the special requirements of the chemical pipeline.
(3) welded steel pipe for low pressure fluid delivery
Low voltage liquid transportation with welded steel pipe is welded tube, generally with the Q215-A, Q235-A, Q255-A of ordinary carbon steel, galvanized according to the quality of the surface (Bai Tieguan) and stainless steel (black pipe); according to the pipe end threaded or not, and can be divided into threaded and non threaded two; according to the pipe wall thickness, there are two kinds of ordinary and thickening.
Seamless steel pipe has the advantages of high pressure, good toughness, long pipe and low interface. The disadvantage is that the price is high, easy to corrosion, so the service life is short.
