Product Description

Industrial steel jacket steel insulation pipe outer protective layer stability

Steel jacket steel composite insulation steel pipe is one of the underground directly buried pipes, the use of no concrete structure can also be buried underground, that is, the thermal expansion of the working steel pipe is carried out in the outer pipe, which reduces the material cost, shortens the construction date, and guarantees the safety of the heating pipe, can be widely used in different temperature environments more safely. Especially suitable for high temperature steam pipeline projects. The operating temperature can reach 150ºC-450ºC. Pipe ports are generally sealed with polyethylene film or three-layer PE cold wrap to prevent moisture or water from entering before installation or during construction. The multi-layer staggered binding of the insulation material effectively reduces the heat loss, and control measures are taken on the surface of the coat to prevent the generation of cold bridge, so that the temperature control of the coat anti-corrosion layer is guaranteed. The thermal insulation material is used to wrap the multi-layer aluminum foil reflector, which effectively reduces the heat loss and makes the steam pipeline more economical and reasonable. The drainage system adopts completely closed form, flexible layout, reasonable structure, safe and reliable. The drain pipe on the steel bushing can not only discharge the humid gas in time, but also be used as the alarm signal pipe for daily operation. The thermal compensation of the pipeline adopts high quality bellows compensator, which is installed in the casing and made into direct buried form, no need to set observation Wells, convenient operation and short construction period. Suitable for conveying 2.5MPa, 350 degrees Celsius below the steam or other media, the product with steel pipe as the outer protective layer, with high strength, not easy to damage, easy maintenance, long service life advantages.

Product Description

Steel jacket steel steam insulation pipe is composed of outer steel pipe plus steel pipe anticorrosion, insulation layer and inner working steel pipe. Steel jacket steel steam composite insulation pipe is suitable for conveying 2.5MPa, 350 degrees Celsius below the steam or other media, the product with steel pipe as the outer protective layer, with high strength, not easy to damage, easy maintenance, long service life advantages.
Steel sleeve steel insulation pipe is mainly composed of working steel pipe, insulation layer and outer steel pipe.
The material is often carbon steel or alloy steel, mainly used for conveying media, such as conveying steam, hot water and so on. There are many options for insulation materials, such as glass wool, which is an inorganic fiber material with good thermal insulation performance and stable chemical properties; There is also polyurethane foam, which has excellent insulation effect and can effectively reduce heat transfer. The outer steel pipe mainly plays a protective role, usually spiral steel pipe or straight seam steel pipe, and the material is mostly Q235B steel, which can prevent the internal thermal insulation layer and working steel pipe from being damaged by external factors such as groundwater erosion and external impact.

Company Profile

Our Advantages

Common materials of insulation layer:
Rock wool: It is an inorganic thermal insulation material, which is made of natural rock after high temperature melting, through centrifugation and other processes. It has good thermal insulation performance, and excellent fire performance, and can reach class A non-combustible, for example, rock wool is often used as a thermal insulation layer material in some thermal pipe insulation projects with high fire protection requirements.
Aluminum silicate cotton: also inorganic fiber insulation material, is made of hard clay clinker and other raw materials, high temperature resistance is outstanding, long-term use temperature can reach 1000ºC, so in the transport of high temperature media steel sleeve steel insulation pipe is also more widely used, can effectively block the heat transfer.
Polyurethane foam: This is a kind of organic insulation material, formed by chemical foaming process, with low density, good insulation effect, high closed cell rate characteristics, can well prevent heat conduction, but its fire performance is relatively weak, more used in the temperature is not particularly high and the fire protection requirements are not very harsh insulation pipe.
