Elbow

Carbon Steel &stainless Steel Elbow Elbows are pipe fittings used to change the direction of pipelines in piping systems, commonly employed at pipeline bends. They are widely used in industries such as petroleum, chemical, and power. The common size range for elbows is DN15-DN2000, and typical angles include 45°, 90°, and 180°.

Laser Clad Composite Pipe

Laser clad steel pipes are manufactured using laser cladding technology. This technology involves adding cladding material to the surface of ordinary steel pipe base material, using high-energy-density laser beams to fuse the cladding material with the steel pipe surface, forming a metallurgically bonded cladding layer. These pipes are generally used in compressed air energy storage projects as underground deep well transportation pipes or casings, as well as in oil, natural gas, and geothermal well extraction.
