Alloy Pipe
Alloy Steel Pipe Is A Special Material Between Carbon Steel And Stainless Steel Pipe.
Because Different Rare Elements Are Added To The Raw Material, Its Performance Is More Powerful.
Alloy Steel Pipes Are Generally Used For Steam Boiler Pipes, Which Need To Withstand Greater Pressure When Working, And Therefore Require A Higher Production Process.
Typically, The Actual Finished Wall Thickness Of Alloy Tubes Is Generally 1%~10% Higher Than The Required Wall Thickness.

Alloy Steel Pipe Is a High-Grade Carbon Steel, That Adds Rare Elements Such as Chromium-Nickel-Mo to Enhance the Performance and Stability of the Product.
Alloy Steel Pipe Size Needs To Be Calculated By The Inch, Such As a 2-inch Alloy Steel Pipe Caliber Of 2 * 25.4 = 50.8mm.
The Meter Weight Formula Calculation for Alloys Is Fixed. However, Since Different Materials Have Different Densities, The Coefficients We Use Are Different. Therefore, If You Need to Know Its Meter Weight, Please Feel Free to Contact Us.
