SPECIFICATIONS
• Features: flexible connection, strong & anti-corrosive, no need welding, no fire risk, space saving, suitable for any pipe, easy installation.
• Application field: surface pipe, underground engineering, ship building, offshore oil platform, water supply, coal gas supply, natural gas supply, power, industries, sewage treatment & maintenance.
• Application pipeline: crude oil pipeline, gas pipeline, natural gas pipeline, water supply & drainage pipeline, fuel oil pipeline, airline pipeline, automobile pipeline, lubricating oil pipeline, sludge pipeline, suction pipeline, water power pipeline, sea water pipeline, fresh water pipeline, turbine pipeline, air conditioning pipeline, firefighting pipeline, ventilation pipeline, compressed air pipeline.
• Versatility: Apply to any pipe, to connect different materials of different axial, different diameter pipe, for quick repairs.
• Economy: The first pipe needn’t deal with, can be connected, thin-walled, thick-walled tube, the installation is simple, a significant reduction in construction costs.
• Reliability: It can compensate the axial displacement and the angle crab, the apron lip-like structure can be increased with the pressure enhanced sealing effect.
