Nanopore insulation material: the nano-scale porous composite material formed by sol gel method, which is composed of reinforcing material and sol and then replaced by gas in the gel liquid phase in a certain drying way
Before construction, cut the nano hole coil material, measure the circumference of the pipe with tape or wire, and consider the size of axial lap joint 30~50mm. The cut length is the pipe circumference + lap joint size.
The horizontal axial lap joints of each section of nanocomposite coil shall not be arranged within the range of 90° to the left, right and above the vertical center line of the pipeline. As shown in the figure below.
Every nanopores insulation between first with galvanized iron wire (0.5 mm or 1 mm Φ Φ) or banding steel belt, not by loose phenomenon, then the other end fixed on the pipe in the same way, every section of the heat preservation material ring to the seam should be neat, may not appear tilt phenomenon, and then in each period of nanopores heat preservation material to reinforce middle strapping, usually for 20 ~ 30 mm, the whole period of heat preservation material shall not be less than minimum 4 pack, with drum tied up or loose place should be strengthened, strapping point should be in the axial catch it.
For double layer or multilayer nanopores insulation construction, should be done step by step a strapping, and USES the internal and external layer of staggered joints, the adjacent two layers of axial seam position shall not be less than 200 mm, the composite insulation structure, the outer layer of traditional construction method of insulation materials can be reference to the above construction of heat preservation materials, namely to squeeze joint, inner and outer layer of staggered joints.
