1. Preheating Preheating helps reduce the peak hardness of the heat-affected zone (HAZ) of medium-carbon steel and prevents cold cracking. It is a key process measure for welding medium-carbon steel. Preheating also improves joint plasticity and reduces post-weld residual stress. Typically, the preh Read More

Information about Alloy Steel PipesSteel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, gas, water, and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight while mai Read More

Applications of Stainless Steel Pipes in Marine EngineeringStainless steel pipes are widely used in marine engineering. The two major systems in shipbuilding and offshore engineering generally require three types of steel pipes: pipes in conventional systems, pipes used in structures, and pipes for Read More
