The scope of application of the welded flange

Boiler and pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, food and other industries.
Welded flange during use the cathodic protection valve at the transmission and distribution network Louzhuang isolation and the need for potential fragmentation (district) of buried pipe valve wells. Welded flange slice of the buried transmission and distribution network (district) isolation can clearly grasp the film pipeline cathodic protection (district); adjacent sheets (area) protection potential difference between the larger and fail to protect the potential requirements of on-chip (area), can not reach to protect potential requirements of on-chip (district) special handling up to meet the requirements until later contiguous; cathodic protection fragment (district) evaluation of treatment for different cathodic protection; when the protective potential of adjacent sheets (area) the same (or similar) to achieve the requirements of the protection potential, the available cross bar on both sides of the insulating flange connectivity unified protection.hydraulic hose cutting machine
Welded flange in accordance with certain principles and the principle of production and use in the production and use, to ensure the correct ways and means to provide good value and role.metric hydraulic fittings
