Square pipe fitting is kind of square body

　　The square is a square, called pipes, is equal to the length of steel pipe. After the process of strip is rolled. The general is to strip after unpacking, smooth, curly, circular tube is formed by welding, pipe rolling into squaretube and then cut into required length. The average is 50 per package.

　　Square seamless and weld points, seamless pipe is extruded into a seamless pipe.

　　The performance index of 1 square - plastic analysis

　　Plastic refers to the metal material under load, plastic deformation (permanent deformation) without destroyingthe ability.

　　The performance index of 2 square - hardness analysis

　　Hardness is a measure of the pointer degree of soft metal materials. In the current production of hardness testing method is the most commonly used method of indentation hardness, it is with a certain pressure headgeometry under load is pressed into the metal surface to be tested, according to the degree to be pressed into the determination of the hardness.

　　We have adopted advanced production equipment and technologies to manufacture our pipe elbow and blind flange, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
