Longitudinal Submerged Arc Welding Pipe (LSAW) Properties and Uses Longitudinal submerged arc welding pipe (LSAW) pipes have high strength and pressure resistance. They are widely used in long-distance, large-diameter oil and gas transmission pipelines.  The LSAW pipes are suitable for high-pressure environments. The size of LSAW pipes is accurate, good roundness…

The globally popular Chinese animated film “Nezha” has attracted widespread attention. In the ancient Chinese mythological stories, deities wield various magical weapons; Nezha himself is known for his four great treasures: the Fire-tipped Spear, the Universe Ring, the Cosmic Wheels, and the Scarlet Sash. Modern technology have made these mythical…

1Cr17Mn6Ni5N stainless steel is instead of grade 1Cr17Ni7, it is with magnetic properties after cold rolled, used for railroad cars. 1Cr17Ni7 stainless steel has high strength after cold working for railroad cars, conveyor belts, bolts and nuts. 1Cr18Ni9 stainless steel  has high strength after cold working, but the elongation is…

Cold-rolled sheets have good surface quality, high dimensional accuracy and no oxide sheet due to rolled at room temperature. After annealing treatment, its mechanical properties and technological properties are better than hot-rolled sheet, mostly used of automotive, electrical products, locomotives, aviation, precision instruments, food and other industries. In the planning and design…

In the foundry industry, common modeling techniques take CNC wood modeling, foam molding machines, CNC EPS machining centers and tranditional sand casting lines, these methods have different application scope, casting precision, and cost. CNC Wood Modeling CNC Wood Modeling utilizes CNC machinery to carve models out of wood or other…

The service life of the electrode is related to the furnace charge, equipment, operation and the quality of the electrode. The furnace charge must not contain non-conductive materials such as mud and stones, rubber and wood. During operation, the furnace operators need to especially care about a few of key…
