Steel jacket steel steam insulation steel pipe 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 steam insulation steel pipe
Steel pipe knowledge explanation
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 standards of the assembly process, carefully implement the quality technical specifications of the construction pipeline, 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.
Insulation steel pipe manufacturing considerations
Such as environmental conditions, whether there are corrosive substances in the surrounding environment, the ambient temperature and humidity of the location, and the laying method. These are important considerations in the manufacture of steel jacket steel insulation pipe
If the thermal insulation performance of the steam insulation pipe transported by the steel pipe as a medium is not good, it will not only increase the heat loss, but also affect the economic benefits of long-distance transportation.
The insulation data of the steel pipe is generally glass wool as the main data, and then the polyurethane rigid foam composite outside the glass wool is the second insulation data, and the steel pipe needs to be coated with an anti-corrosion layer
However, temperature inhomogeneity is also a major consideration in data use and data selection, with some suitable for high temperatures above 250 degrees Celsius and others up to 250 degrees Celsius and below.
