High-pressure seamless steel pipe material introduction and process steps
High-pressure seamless steel pipes are high-pressure boiler pipes because high-pressure seamless steel pipes are usually used in high-temperature and high-pressure boiler pipes, so they are also called boiler pipes. Although the above two pipes are called differently, they are the same They all b...Read more -
The difference between push steel elbow and socket welding steel elbow
Push-made steel elbow: The process of pushing steel-made steel elbows with machinery + mold inner tube + intermediate frequency heating method, but later it is probably difficult to control the inner and outer wall thickness, and it is rarely used in practice. Socket welded steel elbows: most are...Read more -
The difference between HFW steel pipe and ERW steel pipe
The difference between ERW (straight seam electric resistance welded) steel pipe and HFW (high frequency welded) steel pipe is mainly the principle. As the name implies, resistance welding is a method in which pressure is applied through electrodes after the weldment is combined, and the resistan...Read more -
Comparison of galvanized spiral steel pipe, straight seam steel pipe and galvanized seamless steel pipe
The production process of galvanized straight seam welded pipe is relatively simple. The main production processes are high frequency welded straight seam steel pipe and submerged arc welded straight seam steel pipe. Straight seam pipe has high production efficiency, low cost, and rapid developme...Read more -
Quality requirements for seamless steel pipes
1. Chemical composition of steel: The chemical composition of steel is the most important factor affecting the performance of seamless steel pipes, and it is also the main basis for formulating the parameters of the rolling process and heat treatment of seamless steel pipes. (1) Alloying elements...Read more -
Product advantages of anti-corrosion steel pipe
1. Combining the mechanical strength of steel pipe and the corrosion resistance of plastic; 2. The outer wall coating of the anti-corrosion steel pipe is more than 2.5mm, which is scratch-resistant and bump-resistant; 3. The friction coefficient of the inner wall of the anti-corrosion steel pipe ...Read more
