Double flanged limit expansion joint consists of ontology, sealing ring, gland, and shorten the pipe and other major parts. The loose tube expansion joint add spacing device, on the basis of the original performance in the largest scale in double nut lock. Pipeline in the scale of allowing free expansion, once more than its largest scale, limit, ensure the safety of pipeline operation, especially suitable for the vibration or have a certain slope and curve of pipeline connection. Double flanged limit expansion joint structure

double flange limit expansion joint characteristics 1. Simple installation, convenient Industrial Valves installation, affordable pipeline axial tension. 2. The product adopts the casting or welding metal, loose tube parts choose trapezoidal rubber seal, in the gland and bolt under the action of 3. Using the rubber compression elastic deformation principle. Forced sealing ring deformation on the outer wall of pipe joint ontology between static seal. 4. Metal and seal strictly according to the using performance and user requirements. External coating material high strength anti-corrosion paint, by connecting bolts for high strength carbon steel or stainless steel. Because of a certain gap between ontology and telescopic tube, make it has a certain axial and radial displacement. 5. Can effective compensation and relief pipe in the pipe and blind thrust plate, and to facilitate pump, Industrial Valves replacement, installation and maintenance is a pipe installation in the shipping industry is the most ideal accessory products.
