What is the seamless carbon steel pipe?
2023 / 11 / 13
What is the seamless carbon steel pipe? Carbon steel seamless pipe is a kind of long strip steel. The steel pipe has a hollow cross-section and is used in a large amount as a pipe for conveying fluids, such as pipes for transporting petroleum, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipes have the same light-bearing and torsional strength and lighter weight. They are economical cross-section steels and widely used in the manufacture of structural and mechanical parts such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolds used in construction. The use of steel pipes to make ring-shaped parts can increase the material utilization rate, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing. The steel pipe is also an indispensable material for various conventional weapons. The barrels, barrels, etc. must be made of steel pipes. Steel tubes can be divided into round tubes and shaped tubes according to the shape of the cross-sectional area. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported by the circular tube.

Hot rolled seamless steel pipe professional production
2023 / 10 / 23
Hot rolled seamless steel pipe: hot rolling is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. The hot rolled seamless steel pipe has the advantages of destroying the casting structure of the ingot, refining the grain of the steel and eliminating the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved. At the same time, after hot rolling, the non-metallic inclusions (mainly sulfides and oxides, as well as silicates) inside the steel are pressed into sheets, the phenomenon of lamination (interlayer), and the residual stress caused by uneven cooling, which is not easy to control the shortcomings of thickness and side width. It can be said that the hot-rolled seamless steel pipe is suitable for customers who do not have strict wall thickness requirements, and has higher economy.

Introduction and application of galvanized pipe
2023 / 09 / 22
Galvanized pipe, also known as galvanized steel pipe, divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages. The cost of electrogalvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot dip galvanized pipe. 1. Hot dip galvanized pipe is the reaction of molten metal with iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. 2. Cold galvanizing is electric galvanizing, and the amount of galvanizing is very small, only 10-50g/m2, and its own corrosion resistance is much different than that of hot-dip galvanized pipes. The zinc layer is thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. Therefore, its corrosion resistance is poor. Hot dip galvanized steel pipe is widely used in const
