Polyurethane corrosion insulation elbow (Liu: 15233773150 Q: 501638796) is holding a pipe in insulation elbow constituted jacket is made of high density polyethylene pipe, polyurethane foam pipe insulation and working closely together. Used as heat insulation elbow main steering straight, usually supporting the use of pipe insulation, pipe insulation works is based on the design for the compensation effect, so that the site can have elbow insulation properties meet the standard elbow angle: 30 degrees, 45 degrees, 60 degrees, 90 degrees. Insulation elbow widely used in liquid, gas delivery pipe, chemical pipe insulation projects in petroleum, chemical, central heating network, central air conditioning and ventilation pipes, pipe bends in municipal engineering. Pipe insulation (including elbows, tees, crosses) is a good insulation properties, plus safe, reliable, low construction cost of prefabricated buried pipe insulation. Useful handled heating, cooling, heat, electricity, chemicals and other projects in the pipeline insulation pipe insulation, curved pieces of insulation, sliding lubrication, exposed pipe end, Ba bend waterproof, corrosion and other questions. Not only has the traditional laying of the pipeline trench and overhead difficult to compare the advanced technology, useful properties, but also has significant social and economic benefits, energy saving benefits.
