Hot Expanded Seamless Steel Pipe

Compared with hot rolled seamless steel tube whose production cost is high, hot expanded seamless steel pipe has the advantages of easy production, low production cost, high production efficiency, stable quality and low price. Hot expanding technology is mainly applied in producing fluid delivery pipe, petroleum and natural gas pipeline, mechanical tube and pressure tube.

At present, our company is equipped with two professional hot expanded seamless steel tube production lines with the production volume of more than 2000t per month. We also have professional straightening machine to guarantee the straightness of our finished product conforms to the standard.The hot expanded seamless steel pipes we produced are mainly exported to Europe and North America.

As market competition is getting more and more fierce in pipe industry, for the sake of profits, some other pipe suppliers may offer customers welded pipes with welding seams removed rather than real seamless pipes. We may not make sure our pipe price is the lowest in the market, but we promise that we will lower the price to the lowest possible extent without sacrificing pipe quality. Apart from using our own steel pipes, our company can also use the steel pipes made by TPCO (Tianjin Pipe Corporation) to manufacture the hot expanded seamless steel pipes for you. All our seamless steel tubes are of reliable quality. You can do any inspection to our products before delivery.
