three。 The welding of polyurethane insulation pipe is a key work to ensure the engineering quality, in the construction of prefabricated directly buried pipeline. The construction steel house has raised the price sharply and found that the problem can be solved in time. If the problem cannot be solved on the spot, the user should be notified and reported to the supervisor at the same time *;
Fengxin County thermal FRP wound rock wool thermal insulation steel pipe widely used in the construction of prefabricated directly buried insulation pipe patching method should pay attention to: 1, the construction should avoid the immersion of groundwater and Rain Water, if the end is inadvertently immersed in water, drying treatment should be done before connecting the jacket. 2. The pipe should be stored in a flat site, neatly placed, and the height of the pipe should be less than m. 3. Pipe hoisting is light and light, collision and throwing are prohibited, and straight hoisting of steel wire rope is prohibited. 4. The thermal insulation layer and anti-corrosion coating should avoid direct contact with flame. For on-site installation, please follow the following procedures: pipe trench excavation-base treatment (drainage, sand cushion)-lower pipe-steel pipe welding-inspection (water pressure)-installation (pressure test)-foaming-sealing foam cell. Joint installation, the heat preservation work of the joint is carried out on the project site, including the installation of the joint outer casing, the connection and sealing of the joint outer casing with the supervisor and the foaming work of the on-site joint, but does not include the welding of the joint part of the steel pipe.
When your security management software has a real-time dashboard, it brings all this important information together so that your security supervisors, administrators, and customers have full transparency and insight into what is happening on the property.
Our factory can send personnel to the project site to carry out the heat preservation work of the joint, including the installation of the outer casing of the joint, the connection and sealing of the outer casing of the joint with the supervisor and the foaming work of the joint on site, but it does not include the welding of the steel pipe of the joint.
At about 11: 15 noon, a truck full of lunch boxes drove into the campus of Wuhan No. 14 Middle School. Two drivers in protective clothing parked the car at the door of the dining room, and specially carried more than a dozen incubators from the car to the dining room. The supervisors of the Market Supervision Bureau of Wuchang District randomly took out a box lunch and tested the temperature of the food center on the spot, showing that the temperature was 64.1 ℃.

Rizhao City Housing and Construction Commission requires that external thermal insulation and waterproof construction under ℃ is strictly prohibited-Lanzhou large-scale public buildings must fully implement green building standards from the beginning of the year. Recently, the reporter learned from the Energy Saving Science and Technology Department of Rizhao City Housing and Construction Commission that in order to strengthen the supervision and management of energy-saving winter construction of new buildings and improve the construction quality of building energy efficiency, the department of energy conservation science and technology organized personnel to conduct special supervision on building energy conservation projects under construction in the city. It is understood that the focus of this supervision work is the construction project of the protective structure, and it is strictly prohibited to carry out external thermal insulation and waterproof construction under the ℃. In the process of supervision, in view of the special weather and low temperature conditions, the supervisor instructed the construction unit (construction unit) to immediately stop the thermal insulation and waterproof construction of the external wall, and required to cover the part of the thermal insulation and waterproof material without protective layer in time, affecting the quality of building energy-saving projects.
