x52 line pipe

For typical city walls, commercial and light industrial area, the area inside the light pollution, such as traffic pollution.
Industrial zone of heavy industrial zone of atmospheric a333 grade 6 pipe pollution. Pollution may be because of fuel gas, such as sulfur and nitrogen oxides, or other gas release is a chemical plant or plant. Suspension of particles in the air, as happened in the process of steel production or iron oxide dust deposition can also make corrosion to add.
Coastal areas generally refers to the area within a mile from the beach. However, Marine atmosphere can spread to deep in the interior, especially on the island, prevailing winds from the sea, and the weather. Britain, for example, climate condition is so so, so the whole country to coastal areas. If the wind mixed with the sea fog, especially because transpiration salt deposition agglomeration, and little rain, not often rain, adverse conditions in the coastal area. If there is industrial pollution, corrosion resistance is even greater.
Stainless steel plate used in the grain boundary x60 line pipe corrosion resistance requirements of high chemical resistance, wild outdoor machine of coal, oil industry, building materials heat-resistant parts and heat treatment are difficult parts.
Stainless steel plate in different concentration and temperature of organic acid and inorganic acid, especially in oxidizing medium has outstanding resistance to abrasion function, used in the manufacture of the fabrics of wear resistant acid containers and equipment and pipelines.
Stainless steel tube is to rely on the appearance of 316l stainless steel pipe the rich chromium oxide film (protective film), and corrosion resistance ability. When this layer of protective film is destroyed, will naturally appear rusty phenomenon.
304 stainless steel tube, for example, in the monotony of clean air, has a certain talent for corrosion protection, but it will be moved to the coastal areas, in contains large quantities of salt sea fog, will soon be rusty; The 316 steel pipe is outstanding. Not any kind of stainless steel pipe, therefore, in any environment ingeneral, corrosion is not rust.
Mesh belt type light heat treatment furnace. This furnace is suitable for small diameter thin-walled steel tube, hour yield of about 0.3 to 1.0 tons, processing steel tube length can reach 40 meters, can also deal with rolls of capillary.
Muff type light heat x70 line pipe treatment furnace. Steel pipe in a continuous rack, running in the muffle tube heating, at a relatively low capital deal with small diameter thin-walled steel tube, hours production at about 0.3 tons.
Penetration depth of molten stainless steel welded pipe requirements, do not contain oxide inclusions, heat affected zone as small as possible, argon arc welding of tungsten inert gas protection has good adaptability, high welding quality and good fusion function, its products in the chemical industry, nuclear industry and food industries widely used.
