Description :

　　Prefabricated steel sleeve insulated steel pipes have successfully solved the difficulties of waterproofing and leakage resistance by utilizing the high strength and good sealing properties of steel sleeves. Using steel pipes as the outer protective layer has the characteristics of high strength, resistance to damage, and ability to withstand the load on the upper part of the trap. In order to achieve long service life, anti-corrosion treatment is required for the steel outer casing to ensure the safety of the heating pipeline. It can be widely used safely in different temperature environments, especially for high-temperature steam pipeline projects. The sliding bracket and internal fixation in the steam pipeline are insulated with special materials to prevent the formation of thermal bridges, thereby ensuring the temperature control of the outer anti-corrosion layer. Fiber winding reinforced fiberglass outer protective tube has good rigidity and waterproof performance, and its excellent corrosion resistance makes it suitable for various complex soil environments. The anti-corrosion of the outer steel pipe can be achieved by combining anti-corrosion coating and cathodic protection, which greatly increases the anti-corrosion service life. The drainage system adopts a fully enclosed form, with flexible layout, reasonable structure, safety and reliability

　　The insulation structure of steel steam insulation pipe manufacturers is divided into internal sliding type and external sliding type according to different sliding methods. Internal sliding type: The insulation structure consists of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, insulation layer, stainless steel fastening steel strip, aluminum foil reflection layer, polyurethane insulation layer, outer steel pipe, and external anti-corrosion layer. External sliding type: The insulation structure consists of a working steel pipe, a glass wool insulation layer, an aluminum foil reflective layer, a stainless steel fastening strap, a sliding guide bracket, an air insulation layer, an external protective steel pipe, and an external anti-corrosion layer. Below 350 ℃, centrifugal glass wool is an insulation material with light weight and stable geometric shape. It is wrapped with multiple layers of staggered seams, effectively reducing heat loss. At the same time, measures are taken to control the surface of the outer jacket to prevent the formation of cold bridges, ensuring temperature control of the anti-corrosion layer of the outer jacket. And it has the characteristic of fully recovering its physical properties and geometric shape after drying in water.

　　Difficulty in draining the pipeline, high pipeline vibration, and damage to the bellows compensator caused by steam water impact. The steam pipeline design set by the user has a steam flow rate of 100T/H. So the calculation results of the insulation structure will be very different. If the soil is calculated, the surface temperature of the pipeline will be too high or too low, thereby damaging the pipeline protective layer. Therefore, the locally measured soil thermal conductivity should be used for calculation. Shijiazhuang Heating Headquarters and other units adhere to the scientific attitude of measuring thermal conductivity. Reduce project costs. Less land occupation, faster construction, and favorable environmental protection. Anti corrosion, good insulation performance, and long service life. Low heat loss, energy-saving. Safe. High density polyethylene plastic protected polyurethane foam prefabricated directly buried insulation pipe is very popular because of its excellent performance, convenient construction and long service life (30-50 years). Its structure is composed of three parts: external protection layer, insulation layer and anti leakage layer. The external protection layer is made of polyethylene jacket pipe or glass fiber reinforced plastic or other materials.

　　It is widely used in the insulation and cooling engineering of stainless steel pipes in urban centralized heating, warm rooms, cold storage, coal mines, oil ports, chemical and other industries. The main feature of stainless steel pipes is that stainless steel materials can be implanted into the human body as healthy materials. Therefore, for water supply pipes, choosing stainless steel pipes is healthy. The immersion water test showed that all indicators met the requirements of relevant drinking water standards. The inner wall of stainless steel pipes is smooth, and long-term use will not accumulate scale or be easily contaminated by bacteria. There is no need to worry about water quality being affected, and it can also prevent secondary pollution of water. The thin and dense chromium rich oxide film on the surface of stainless steel makes stainless steel water pipes have good corrosion resistance in all water qualities, including soft water, even when buried underground; Field corrosion test data shows that the service life of stainless steel water pipes can reach 100 years, with almost no maintenance required during the service life cycle, avoiding the cost and trouble of pipeline replacement. The comprehensive use cost is low, and the inner wall of stainless steel pipes is smooth with very low water resistance, reducing pressure loss and lowering transportation costs. Due to the low coefficient of thermal expansion of stainless steel, it effectively reduces thermal energy loss in hot water pipelines. Stainless steel material is a renewable material that does not cause environmental pollution. Stainless steel pipes can be widely used in cold water, hot water, drinking water purification, air, gas, medical gas, petroleum, chemical, water treatment and other pipeline systems. The directly buried polyurethane insulation pipe can play a good anti-corrosion role because the polyurethane rigid foam insulation layer is closely bonded to the steel pipe skin.
