1. Keep warm by smearing of
anti-corrosion steel pipes:
Mainly use uncertain insulation materials, and add a certain amount of adhesive. Or add a coagulant to it, select the proportion of ingredients, add water, and mix evenly to form a shaped mud mass, and then spread it evenly with your hands. This method of spreading is called the smearing method for heat preservation.
2. Wrapped insulation of anti-corrosion steel pipes:
①The winding heat preservation method is mainly to make the heat preservation material into a rope or strip shape, and then directly wind it on the pipe that needs heat preservation.
②The main insulating materials using this method in daily life are: slag wool felt, glass wool felt, straw rope and asbestos belt, etc.
3. Prefabricated components for insulation:
①Pipeline prefabricated insulation structure. When the pipe diameter is DN≤80mm, use a semicircular shell. If the pipe diameter is DN ≥ 100mm, fan-shaped or trapezoidal tiles are used.
②Materials used in prefabricated products are mainly foam concrete, asbestos, slag wool, glass wool, expanded perlite, calcium silicate, etc.
4. Filling method heat preservation of anti-corrosion steel pipes:
① If the insulating material is bulk material, this method can be used for detachable insulating material.
② During the construction process, fix the round steel support ring on the pipe wall. The thickness of the ring is the same as that of the insulation layer, and then the support ring is wrapped with an iron sheet, aluminum sheet, or wire mesh to fill the insulation material.
③ This filling method can use prefabricated hard arc bricks with porous materials as the supporting structure, and the distance between them is about 900mm, just like plain wire mesh, according to the outer circumference of the insulation layer of the pipe, the slag is processed by a circular machine By covering the perimeter of the support, the filling and insulating structure should be made as far as possible from a metal protective shell.
