For the thickness of Φ 680 mm steel pipe, we can process into thickness of 8 mm - 60 mm steel tube; the largest rolling width from 2400mm Φ680mm-Φ7000mm into the thickness of 60-150 - mm steel tube. Rolled maximum width is 3000 mm.
Anti-corrosion method:
From the perspective of the inhibition one of process. Such as anti-corrosion coating in the outer wall , which increases the loop resistance, reduce corrosion current; in addition , with dc power supply, which make the steel pipe become negative potential to the soil, thus develop a cathodic protection, and can eliminate the cathode and anode. Each steel piling pipe for acceptance inspection are marked with fadeless paint, The. And brushing 50 mm wide white pain at circumference about 200 mm from the inside of the tube end. bending steel pipe for the red paint to distinguish it
1. The color should be marked, to guarantee the piling steel pipes exposed to air do not fade at least 4 months ;
2.The marking color should be 200 mm from end face, and brush the circular , at least 25 mm for the height of each letter;
3.Use metric units;
4.steel Piling pipe number should be in sequence;
5.steel Piling pipe are all identified ;
6.make the following die tag at the pipe end surface of longitudinal seam.
Steel Piling Pipes are made by steel plate or strip steel with welding after rolling modeling,specification fromφ680-φ7000,
different pipe thickness .Implement the standard SY/T5037-2000, GB/T9711.1-1997 and APISpec5L.
widely used in LNG, petroleum, chemical, electric power, heat powerwater supply and drainage, steam heating, pressure steel pipe forhydropower statio, thermal power, headwaters and other long distance pipelines.and engineering field such as Piling,wind tower drum steel structure, Bridges, offshore platform high-rise building
