Special Flanges - Spectacle Blinds, Spades and Ring-Spacers

Spectacle Blinds are generally applied to permanently separating pipesystems, or just to connect with each other. A Spectacle Blind is a steel plate cut into two discs of a certain thickness. The two discs are attached to each other by section of steel similar to the nose piece of a pair of glasses.

Galvanized steel pipe welding technology

Welding galvanized steel pipe should be based on a matrix material selection, general ease of low carbon steel due consideration, the choice of J422 is more common. Welding techniques: the first layer of multi-layer welding weld seam, try to make it melt the zinc layer vaporization, evaporation and escape the weld, which can greatly reduce the liquid zinc remain in the weld.
