Steel sleeve steel insulation pipe structure characteristics knowledge
The types of building materials in the market are gradually increasing, among which the thermal insulation products of thermal insulation materials, the buyers look stable for a long time, and the buyers in general are still very concerned about the price when buying, so we will first discuss the knowledge of steel jacket steel insulation steel pipe
Steel sleeve steel insulation steel pipe knowledge
New anti-crack, non-penetration, anti-pressure, closed placement process - steel sleeve steel insulation pipe placement process. Such a process is a major achievement in placing processes in areas with high water prices.
The tube of conveying medium, the corrosion-resistant outer tube and the ultra-fine glass wool or aluminum silicate wire wool supplementing between the tube and the outer tube constitute the steel sleeve steel insulation steel pipe.
Steel insulation steel pipe can also be made of ink material, supplementary insulation foam combined, the key situation of the external maintenance pipe of the insulation pipe is the stability of close waterproof and has excellent tensile strength.
Its heat resistance is difficult to match by other external maintenance management agencies, mainly because of the high toughness, welded connection, waterproof and sealing characteristics of the steel shell.
The basic standard of steel sleeve steel insulation steel pipe assembly process, carefully implement the construction pipeline quality technical specifications, before the implementation of the pipeline project, please carefully consider whether the size, information and formulation of the pipeline meet the requirements, and follow the requirements of rust removal, oil brushing and pipeline scaling
The facilities of steel sleeve steel insulation pipe: first large than small, first function, then branch, first rise and then fall, the water supply system is equipped with water valve below, the high level is equipped with active water valve, pipeline construction should meet the "big, small, first up, down, first out" standard. According to the requirements, the pipeline construction should be completed after the hydraulic test.
Steel sleeve steel insulation pipe structure characteristics
The steel jacket steel insulation pipe is composed of the steel pipe of the conveying medium, the anticorrosive coat steel pipe and the ultra-fine glass wool filled between the steel pipe and the coat steel pipe, and it can also be combined with the graphite, silicon calcium tile shell and the filled polyurethane foam.
Steel casing embedding technology is a new waterproof, leak-proof, impermeable, pressure-resistant and completely closed embedding technology, which is a major breakthrough in the use of direct buried technology in areas with high water table. The main problem of the protection pipe of direct buried pipeline is the reliability of tight waterproof, and it needs to have good mechanical strength.
Due to the high strength of the steel shell, the use of welded connections, waterproof sealing performance is very reliable, in addition, its high temperature resistance is also unmatched by other external protection management agencies, in areas with high groundwater levels, in order to ensure that groundwater does not affect the normal operation of the directly buried pipeline, the outer protective layer uses a strong and airtight steel pipe shell.
