Hebei Haihao Group Huadian High Pressure Pipe Fittings Co., Ltd. possesses several thousand-ton hydraulic presses, which are high-efficiency, high-precision equipment specifically designed for the hydraulic forming of pipe fittings. These machines are widely used in the processing of pipe fittings such as tees, crosses, and elbows made from stainless steel, carbon steel, copper, aluminum, and other materials. The equipment features a frame or four-column structure, offering strong rigidity, high precision, stable operation, and excellent resistance to misloading. Utilizing hydraulic oil or liquid as the working medium, the system applies ultra-high pressure internally to the pipe blank through a high-pressure mechanism. Combined with axial feeding and radial thrust, the pipe undergoes plastic deformation within the mold, conforming to the shape and achieving seamless connections. The formed texture is clear, with excellent surface quality, eliminating the need for subsequent welding and delivering higher strength.
Hebei Haihao Group Huadian High Pressure Pipe Fittings Co., Ltd. possesses several cutting and forming production line platforms. The steel pipe blanking and cutting equipment is a high-efficiency automated cutting system specifically designed for batch processing of steel pipes, widely used in construction, machinery, piping, manufacturing, and other fields. The equipment employs CNC control technology, combined with servo drives and high-precision transmission mechanisms, to achieve automatic feeding, fixed-length cutting, and multi-specification switching, significantly improving processing efficiency and precision. The equipment can be adapted to various cutting methods, such as disc saws, abrasive wheel saws, plasma or laser cutting, meeting the needs of materials like carbon steel, stainless steel, and alloy steel. The cutting surfaces are smooth with minimal burrs, eliminating the need for secondary processing. With an automated loading and unloading system, the machine features a robust structure, stable operation, and a user-friendly interface, supporting multi-batch and multi-size program memory for batch management. It is equipped with safety protection devices and dust removal systems to ensure operational safety and a clean environment.
