Compared with seamless pipe, galvanized pipe and other steel, welded pipe has some outstanding characteristics. First of all, it is very simple to judge whether there is weld on the steel surface. Because the welded pipe is made by welding, it has obvious characteristics. Secondly, the diameter of welded pipe is generally large, and the diameter of seamless pipe and galvanized pipe is relatively small. Therefore, A572 grade 42 high strength steel, welded pipe is generally used in underground pipeline to transport water, gas, air, oil and heating steam with low pressure.
Our client purchase more than 900 tons pipe A572 grade 42 high strength steel from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as A572 grade 42 high strength steel and stainless steel. The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process. It is one of the series of steel with world advanced super steel technology.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another A572 grade 42 high strength steel magnificent projects.
