the content of several common elements in the seamless steel pipe will give you a brief introduction:(1) carbon; the higher the carbon content, the higher the hardness of the steel, but the worse its plasticity and toughness.(2) sulfur: it is a harmful contaminant in steel. when steel with high sulf

in the process of anti-corrosion construction of oil and gas pipelines, the surface treatment of seamless steel pipes is one of the key factors to determine the service life of pipeline anti-corrosion. according to research by professional research institutions, the life of the anti-corrosion layer

improper storage of seamless pipes will lead to rust, corrosion, etc., so how to save seamless pipes is correct? 1) the place or warehouse where steel is stored should be located in a clean place with smooth drainage, away from factories and mines that produce harmful gases or dust. weeds and a

1) differences in technology1. cold-rolled section steel allows local buckling of the section, so that the bearing capacity of the member after buckling can be fully utilized; while hot-rolled section steel does not allow local buckling of the section.2. the reasons for the residual stress of hot-ro

1. welded steel pipes for low-pressure fluid transportation (gb/t3092-1993) are also called general welded pipes, commonly known as black pipes.it is a welded steel pipe for conveying general lower pressure fluids such as water, gas, air, oil and heating steam and other purposes. steel pipes are div
