Widely used in shale oil and gas extraction, temporary oil transfer, emergency drainage, municipal pipeline rehabilitation, fire water supply, and agricultural irrigation—particularly suitable for large-diameter, high-pressure pipeline systems.
Structure: The LDHC large diameter hose flange coupling features a split loose-flange design, consisting of a flange plate, tongue-and-groove sealing surface, loose flange assembly, and matching gasket. The coupling allows radial rotation and axial sliding. During installation, evenly tightening the flange bolts brings the two flange faces and the gasket into close contact, forming a highly reliable sealing system.
Material: Manufactured from premium carbon steel, stainless steel, or alloy materials, the coupling delivers exceptional mechanical strength and corrosion resistance, capable of withstanding high-pressure, high-temperature, and corrosive media environments. Material options can be tailored to specific working conditions to meet the demanding requirements of heavy-duty systems in petrochemical, chemical, power generation, marine, and mining applications.
Installation: Installation is straightforward—simply align the flange faces, insert the matching gasket, and evenly tighten the bolts in a symmetrical, step-by-step sequence. The process is quick and requires no special tools, significantly saving installation time and minimizing human error. The coupling is available in multiple specifications and compatible with ANSI, DIN, JIS, and other international flange standards to meet diverse engineering requirements.
