First, directly buried polyurethane insulation pipe durability and stability analysis

(A) the structure is clear: the foundation of stability

Directly buried polyurethane insulation pipeline main structure by the working steel pipe, polyurethane foam and high-density polyethylene jacket pipe of the three core components of the clever combination. This clever structural design, for the excellent durability and stability of the pipeline has laid a solid foundation, so that it can be in the complex and changeable underground environment for a long time stable operation, and effectively resist the attack of various external adverse factors.

(B) Polyurethane foam: the key to seismic cushioning

Polyurethane foam is widely used in the field of thermal insulation engineering, thanks to its extraordinary thermal insulation properties and stable chemical properties. In the sudden impact of natural disasters such as earthquakes, piping systems bear the brunt, and polyurethane foam by virtue of its far more than the working steel pipe and glass fiber density advantage, can efficiently absorb and evenly disperse the impact to the entire piping system, significantly reducing the risk of pipeline damage, for the safe operation of the pipeline to build up a solid line of defense.

(C) high-density polyethylene jacket pipe: the guardian of pressure resistance

The addition of high-density polyethylene jacket pipe is like a layer of indestructible armor for the pipeline system, which greatly improves the pressure-resistant ability of the pipeline system. In the severe test of natural disasters such as earthquakes, this enhanced structure gives the pipeline higher stability, so that it can comfortably cope with a variety of extreme working conditions, to ensure the continuity and reliability of energy transmission, guarding the safety and stability of critical infrastructure.

(D) Superior thermal insulation: resisting the threat of temperature change

Polyurethane foam's excellent thermal insulation performance also plays a vital role in natural disasters such as earthquakes. Its excellent thermal insulation effect can effectively block the transfer of heat, significantly reduce the risk of pipeline rupture caused by drastic changes in temperature, to ensure that the pipeline in the extreme temperature difference environment is still able to maintain a good working condition, for the stability of energy supply escort.

Second, directly buried polyurethane insulation pipe construction process details

(A) careful preparation before construction

In the formal opening of the construction of the trip before the construction site for accurate positioning and thorough cleaning is a crucial step. This is not only about construction safety, but also to ensure the smooth progress of the project is a key prerequisite. Through careful site planning and debris cleanup, a clean, orderly and safe working environment is created for subsequent construction, laying the foundation for high-quality construction.

(B) materials and equipment ready and complete

Construction materials and equipment are fully prepared to ensure the smooth progress of the project is a powerful support. From high-quality polyurethane insulation pipe, durable steel pipe, to all kinds of professional construction tools, each of which need to be carefully selected, strict control. At the same time, the construction of the foundation for fine processing, to ensure that it is flat and firm, can effectively avoid the pipe in the subsequent use of deformation, damage and other problems, greatly enhance the effect of heat preservation, extend the service life of the pipe.

(C) pipeline installation of precision work

Pipeline installation, with the help of professional equipment for accurate fixing and solid welding is the core essence. Through exquisite craftsmanship and strict operating standards, to ensure that each pipe connection is tight, unbreakable, so as to build a solid and reliable energy transmission network, for the subsequent insulation construction and long-term stable operation to provide a solid guarantee.

(D) pipe patching tight blockade

After the completion of pipeline installation, pipeline welding patch insulation construction must not be ignored. This key step is aimed at welding parts of the tight insulation treatment, fill the possible insulation loopholes, and further enhance the overall insulation performance of the pipeline, to ensure that the heat is efficiently preserved in the transmission process, reduce energy loss, enhance the operational efficiency of the system.
