Comparison for the range of steel pipe over different connection

Not more than 0.5 mm/year is the general corrosion rate for steel pipes. Thus no matter you are seamless steel pipe or ERW steel pipe, you need to focus on the problem coming this aspect once you've used the tubes for a long time. Today, we would have a view for the comparison for the range of steel pipe over tubing with couplings or strengthened connection parts. From the picture below, we can figure out that different steel pipe's type, such as plain without thread or plain as per GOST. From the picture, we can figure out that they would have special nominal diam for the suitable work. at the same, they have special tube wall thickness too. This would finally lead to the high quality work showing for those steel pipes.
