Flowtera Pipe
1 / 5
Alloy steel pipes are manufactured by adding alloying elements such as chromium (Cr), molybdenum (Mo), nickel (Ni), and manganese (Mn) into carbon steel to improve mechanical strength, heat resistance, wear resistance, and pressure-bearing performance.
Our alloy steel pipes include both seamless alloy steel pipes and welded alloy steel pipes, produced in accordance with international standards such as ASTM, EN, DIN, JIS, and GB.
