Structural Seamless Steel Pipe

  We are specialized in manufacturing seamless carbon steel and alloy steel bubes complying with the specifications GB,ASTM,ASME,API,JIS,DIN and BS, and have obtained the American Petroleum Institutes certificate and API certificate for API 5CT, API 5L and API 5D. With the principle of high starting point input and sustainable development, we import high precision and exactitude ACCU-ROLL hot rolled machine, and these producing lines adopt advanced equipment and technology in our industry. The main manufacturing equipments include gasogene stoves, ?14.5m circular heating stoves, punch machines, A-R stretched machines, vertical straightening machines and so on. Circular heating stoves possess many merits, such as symmetrical temperature when heating, lower energy source and metal consuming and so on; billet perforation adopt German advanced technology and select fungiform punch with big extending quotiety and high precision on size.
