Summary Of Knowledge On Anti-corrosion Steel Pipe Products

Characteristics Of Anti-corrosion Steel Pipes

Dimensional Accuracy: For Outer Diameters Below 51mm, The Wall Thickness And Outer Diameter Should Be Controlled Within The ± 0.05mm Boundary. For Outer Diameters Above 51mm, The Wall Thickness And Outer Diameter Should Be Controlled Within The ± 0.08mm Boundary. If There Are Unique Requirements, Please Definitely Talk To Us Before Purchasing Anti-corrosion Steel Pipes

Roundness: For Those With An Outer Diameter Below 42, The Roundness Should Be Below 0.8mm, And For Those With An Outer Diameter Above 42mm, The Roundness Should Be Below 1mm.

Straightness: Straightness For Outer Diameters Below 32<1mm/m，假如外径32以上的，直度>

For Our Production Factory, For Orders With High Straightness Requirements, We Will Definitely Conduct Trial Production Before Starting Mass Production In Small Batches.

Control Of Roughness Of Anti-corrosion Steel Pipes

If It Is A Corrosion-resistant Steel Pipe Produced By Precision Cold Rolling Without Polishing, The Roughness Of The Outer Surface Is Usually Ra ≤ 0.6 μ M, And The Ra Of The Inner Hole Is ≤ 0.8 μ M.

There Are Also Some Manufacturers Or Customers Who Have High Requirements For Anti-corrosion Steel Pipes, Requiring The Roughness Of The Appearance Surface To Be Ra ≤ 0.4 μ M And The Ra Of The Inner Hole To Be ≤ 0.6 μ M. This Requires A Careful Consideration Of Both Internal And External Perspectives.

If The Wall Thickness Of The Anti-corrosion Steel Pipe Is Thicker Than 4mm And The Inner Diameter Is Less Than 10mm, The Roughness Of The Inner Hole Will Be Slightly Worse, Basically Within Ra ≤ 1 μ M
