Yanshan Xingsong Steel Pipe Co

With the continuous development of my country's productivity (Manager Wang
's strict requirements for transportation pipelines, in order to meet the needs of people's daily life and production, steel-sleeved steel steam insulation steel pipes came into being. So what is its development direction now? First of all, the quality of the steel pipe must be improved, and secondly, the glass wool insulation layer in the middle must achieve a better insulation effect. As an anti-corrosion insulation manufacturer, we are working hard towards this goal.
Steel sleeve steel
The insulation structure of prefabricated steel-sheathed composite insulated steel pipes for direct buried high-temperature steam can be divided into two categories according to different sliding methods. The internal sliding insulation structure is composed of working seamless steel pipes, aluminum silicate, drag reduction layer, microporous calcium silicate, heat insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer spiral steel pipe, and outer anti-corrosion layer. The inner sliding insulation steel pipe is composed of a steel pipe for transporting media + composite silicic acid It is composed of salt or microporous calcium silicate + rigid polyurethane foam + outer spiral steel pipe + glass fiber reinforced plastic shell anti-corrosion protective layer structure. The insulation treatment technology of various pipe fitting nodes is mature and the quality is reliable.
