Classification and anticorrosion of oil casing
Oil casing can be roughly divided into 1. The surface casing is according to different usage methods. Second, the middle casing. 3. Production casing. 4. Drilling casing. The surface casing is mainly to suspend and support the subsequent layers of the casing through the casing head installed on t...Read more -
What does the hot rolling process in stainless steel pipe fittings mean
Simply put, the process of rolling stainless steel pipe fittings after heating and controlling them above the recrystallization temperature is called hot rolling. The process of rolling below the recrystallization temperature, including at room temperature, is called cold rolling. Hot-rolled stee...Read more -
What advantages of steel pipe fitting tees
1. It completely solves the problem of mutual friction between the closed surfaces of traditional connecting pipes and affects the sealing; the flow resistance is small, and the resistance coefficient of the stainless steel tee is equal to that of the pipe section of the same length; 2. The stain...Read more -
Position regulation and purity improvement of straight seam steel pipe induction coil
Adjustment of the position of the high-frequency induction coil of the straight seam steel pipe: The excitation frequency of straight seam steel pipe is inversely proportional to the square root of capacitance and inductance in the excitation circuit or proportional to the square root of voltage ...Read more -
Application of straight seam steel pipes in pressure pipelines
The nominal diameter of straight seam steel pipe refers to the series of diameters specified in the standard for straight seam steel pipes. For straight seam steel pipes, pipe fittings, valves, etc., the nominal straight seam steel pipe diameter is represented by the series specified in the stand...Read more
