Read More1. Pollution and corrosion resistance Corrosion is the main enemy of metal pipes. The outer surface of steel, iron and concrete pipes is degraded by soil and ultraviolet rays. The inner walls of pipes made of other materials are prone to rust, be damaged by wear or accumulate debris. However, due to the corrosion resistance of stainless steel, this…
Read More1. Grade and chemical composition The grade and chemical composition of the steel for galvanized steel pipes shall comply with the grade and chemical composition of the steel for black pipes specified in GB3092. 2. Manufacturing method The manufacturing method of the black tube (furnace welding or electric welding) is selected by the manufacturer. Galvanizing uses hot-dip galvanizing. 3.Screw…
Read MoreThe control of the wall thickness of seamless steel pipe is a difficult point in the production of steel pipes. The measures to improve the accuracy of the wall thickness in the production mainly include the following aspects: 1. Tube billet heating Heating must be uniform, and rapid temperature rise and fall are prohibited. The temperature rise and fall…
Read More1) Appearance defects such as crack, folding, heavy skin, hair grain, pinhole. Generally magnetic particle testing or soak detection is used. For ferromagnetic material, magnetic powder assay should be adopted preferentially, because it has higher flexibility of detection; for non-ferromagnetic material, such as stainless seamless steel pipe, soak test is used. 2) Steel pipe end defects. When obligate excision…
