    This project adopts the German technology which can be formed at once and the electronic equipment of German Siemens PRC and English MENT digital direct current adjustive system. The sophisticated technology and precision equipments guarantee the high quality of our products.We strictly implement the standards of GB/T3091-2008,GB/T13793-2008,GB/T9711.1-1997,API 5L,API 5CT ,and adopt hydraulic pressure test, ultrasonic flaw detection on-line, eddy current test, physical and chemical test,and other all-round detection means to make sure that the quality of the steel pipes is reliable and stable. These products are wildly used in the conveyance pipes of petroleum, natural gas, water vapour, and middle-law voltage flammable fluid as well as used in construction structure with wide application and good adaptability.
    In our company,ERW steel pipe’s specification is ∮17-∮610, double submerged arc welded pipe’s specification is ∮325-∮1200,butt-welded steel pipe’s specification is 457-∮2500, material is Q195,Q215,Q235,20#,16Mn(Q345B),A53,ST37,ST52.Standard is GB/T3091-2008,GB/T13793-2008,GB/T9711.1-1997,API 5L,API 5CT.
