PU insulated pipe: From the structural type of the fixed support, it can be seen that it can bear large axial forces but has no capacity to resist radial shear. Therefore, when arranging supports, radial shear on fixed supports should be minimized so that they bear axial forces, thereby ensuring safe use of the fixed supports and safety of the entire pipe network. After the 1970s, foreign countries generally attached importance to the production and application of insulated steel pipes, striving to substantially reduce energy consumption and thereby reduce environmental pollution and the greenhouse effect. From the structural type of the fixed support, it can be seen that it can bear large axial forces but has no capacity to resist radial shear. Therefore, when arranging supports, radial shear on fixed supports should be minimized so that they bear axial forces, thereby ensuring safe use of the fixed supports and safety of the entire pipe network. Steel-in-steel insulated steel pipe insulation structures are classified by sliding mode into the following two types, so mixing efficiency is a very important factor.

In the laying of insulated pipelines, the insulation layer is undoubtedly one of the most important elements; whether it has good thermal insulation performance often determines the evaluation of the entire insulated steel pipe. Introduction to the construction process and advantages of PU insulated steel pipe: Because PU foam insulated pipe has lasting corrosion resistance and aging resistance, it is well received in application and therefore has a large market demand, which in turn places large production-volume requirements on PU insulated steel pipe. Steel-in-steel insulated steel pipe insulation structures are classified by sliding mode into the following two types. The thermal conductivity of high-temperature prefabricated direct-buried insulated pipe is much lower than that of other previously common pipeline insulation materials, improving insulation performance by 4–9 times.
PU insulated pipe, also known as “jacketed pipe,” is produced by a “two-step method” and consists of an HDPE outer jacket, a rigid PU foam pipe, and a steel pipe. The insulation material is rigid PU foam with a density of 60 kg/m3 to 80 kg/m3, fully filling the gap between the steel pipe and the casing and providing a certain bonding strength so that the steel pipe, outer casing, and insulation layer form a firm composite. PU insulated pipe has been a very popular type of insulated pipe in recent years. The reason it is so well received on the market and is applied in thermal insulation, waterproofing, leak sealing, and sealing in industrial sectors such as construction, transportation, petroleum, chemicals, electric power, and refrigeration—serving as an important material for insulation, waterproofing, and sealing projects in these fields—is its excellent thermal insulation performance together with light weight, high mechanical strength, good sound absorption and sound insulation, non-combustibility, resistance to high and low temperatures, corrosion resistance, non-absorbency, and simple, rapid construction. These advantages arise essentially from its structure.
PU insulated steel pipe is suitable for conveying media at temperatures not exceeding 100°C, with occasional peaks not exceeding 120°C. Its performance advantages include:
1. Occupies little land; fast construction;
2. Energy-saving, anti-corrosive, insulating, and long service life;
3. Leakage alarm wires can be pre-installed for convenient later maintenance. Insulating, compressive, and durable
