Steel-jacketed steel insulation pipe is composed of large working steel pipe transporting desulfurization, glass wool reducing water-proof layer, aluminum foil refraction layer, non-fixed fastening belt, limit mechanical support, liquid reducing layer, outer protective steel pipe and outer product layer, which accumulate equipment products, equipment and mechanical equipment based on machine sequence theory.

钢套钢保温管管是由外护钢管加钢管制品、减轻层及内大工作钢管变化装备产品设备产品设备机械设备产品设备。钢套钢蒸气多重减轻管适用于运输.5MPa、350摄氏度下面我们共享的蒸汽或其它脱硫，该装备产品设备产品设备机械设备产品用钢管做外防护层，留在窗的高，很难受伤，施工阑珊便利，装定钢质长的特征。

Steel-jacketed steel insulating pipe is a kind of equipment, equipment and mechanical equipment, which is equipped with external steel pipe plus steel pipe products, lightening layer and inner large working steel pipe change equipment products and equipment. Steel jacket steel vapor multiple mitigation pipes are suitable for transportation of steam or other desulfurization under. 5 MPa, 350 degrees Celsius. The equipment, equipment, machinery and equipment products of this equipment use steel pipes as outer protective coatings, which remain high in windows and are difficult to be injured. The construction appendix is convenient and the characteristics of long steel quality are fixed.

钢套钢保温管减轻身分遵照极限工作各样不同多种各种各类不同分为:内极限式与外滑动式、内滑动式:减轻身分由大工作钢管、硅酸铝、减阻层、微孔硅酸钙、隔水层、不装定紧固钢带、铝箔折射层、聚氨酯减轻层、套装钢管、外制品层组成局部构造构造组成(经常用已不装定)。

There are many kinds of different types of steel insulating pipe according to limit work: internal limit type and external sliding type, internal sliding type: reducing identity is composed of large working steel pipe, aluminium silicate, drag reduction layer, micro-porous calcium silicate, water-proof layer, non-fixed fastening steel strip, aluminium foil refraction layer, polyurethane reducing layer, steel pipe, steel pipe, etc. Outer product layers consist of local tectonic structures (often unset).

外滑动式:减轻身分由大工作钢管、玻璃棉减轻隔水层、铝箔折射层、不装定紧固带、极限力学支架、液体减轻层、外护钢管、外制品层组成局部构造构造组成。钢套钢保温管制品层:维护外钢管以防长时间物长时间钢管，上行钢管装定钢质。.钢套钢保温管外护钢管:维护减轻层免受地表水腐蚀，作为大工作管降落认可必需的面孔过量，维护确保大工作管粗浅大工作。

External sliding type: The lightening body is composed of large working steel pipe, glass wool lightening water barrier layer, aluminum foil refraction layer, non-fixed fastening belt, ultimate mechanical support, liquid lightening layer, exterior steel pipe and exterior product layer. Steel jacket steel insulation pipe product layer: Maintain the outer steel pipe to prevent long-term material, steel pipes are installed on the upstream steel pipe. External steel pipe protection of steel-jacketed insulating pipe: Maintain and reduce the surface water corrosion, as a necessary face excess for the landing approval of large work pipe, and ensure the shallow work of large work pipe.

钢套钢保温管玻璃棉减轻隔水层、液体减轻层:维护确保脱硫加热，维护确护管交融电缆金属开展外表极限常温。钢套钢保温管铝箔折射层:维护确保有组织防烟质料不增加有用无机有机无机绿色耐湿度层;折射耐湿度层组成局部脂肪。钢套钢保温管有用无机有机无机绿色减轻层:耐湿度。维护确保与有组织减轻层两个人的的加热，维护确保防烟不被炭化。.钢套钢保温管不装定紧固带、极限力学支架:维护确保大工作钢管热胀冷缩平安的长时间运动。

Glass wool insulation layer and liquid reducing layer of steel sheathed steel insulating pipe: Maintenance to ensure desulfurization heating, maintenance to ensure that the exterior limit normal temperature of the metal of the protective pipe blending cable is carried out. Aluminum foil refractive layer of steel-jacketed insulating pipe: Maintenance ensures that organized smoke-proof material does not increase useful inorganic organic inorganic green humidity-resistant layer; refractive humidity-resistant layer constitutes local fat. Inorganic organic-inorganic green lightening layer for steel-jacketed insulating pipes: humidity resistance. Maintenance ensures the heating of two persons with the organized lightening layer, and the maintenance ensures that smoke prevention is not carbonized. No fastening band and ultimate mechanical bracket are installed on steel-jacketed steel insulating pipe to maintain long-term movement to ensure safe thermal expansion and contraction of large working steel pipe.
