       The directly buried steel pipe insulation pipe is divided into hot rolling and cold rolling: hot rolling is divided into general steel pipe, low and high pressure heat treatment furnace steel pipe, heating furnace steel pipe, aluminum alloy profile steel pipe, stainless steel plate steel pipe, petroleum cracking pipe, environmental conditions steel pipe and other pipe fittings; Hot rolling is divided into general steel pipes, low and high pressure heat treatment furnace pipe fittings, heating furnace pipe fittings, aluminum alloy profile pipe fittings, stainless steel plate pipe fittings, petroleum cracking pipe fittings and other pipe fittings, and also includes carbon plant thin-walled steel pipes, aluminum alloy profile thin-walled steel pipes, stainless steel plate thin-walled steel pipes, and special-shaped steel pipes.
        The machines and equipment that are likely to be used for directly buried thermal insulation pipes in production and processing include: steel pipe shot blasting rust remover, three PE winding machine and equipment, 27simn seamless splicing steel pipe PE pipe extractor, sand blasting rust removal machine and equipment, pc polycarbonate low-pressure manual drilling machine, foaming polyurethane table, glass fiber reinforced plastic winding packaging machine, two PE coating machine, plastering mortar wet spraying machine and other service facilities and testing instruments for anti-corrosion and thermal insulation engineering projects.
        The heat preservation and insulation of the pipeline will do some harm to the deformation, stability and fatigue elimination of the steel pipe, but it is not good for the heat preservation and insulation of the steel pipe under external forces. In the production and manufacture of hot rolled stainless steel products, the thickness and side width of pipe fittings are not well controlled. Because when the hot deformation and cold contraction are slow, even if the length and thickness of the hot rolled products meet the requirements, there will still be a certain negative difference during cooling. The wider the negative difference is, the more obvious the thickness is.
