Continuous casting shall be adopted for stainless steel pipe fittings, so as to improve the comprehensive yield, and cooperate with out of furnace refining, which significantly improves the production efficiency, omits the blank opening process and saves a lot of energy consumption.The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling, which is connected by special thread for important threading pipe). For some special pipes in order to make up for the impact of thread on the strength of pipe end, the pipe end is usually thickened before threading (inner thickening,HaimenlinnaStainless steel pipe wholesale, outer thickening or inner and outer thickening).Haimenlinna,　　SPHESPHE—& mdash; Hot rolled steel plate and strip for deep drawing.The back side is not protected by argon, and the flux coated welding wire (self protective flux cored welding wire) + TIG process is adopted. In the s, the backing welding wire has been developed. Recently, China has also developed the stainless steel backing welding wire (i.e. flux coated welding wire, such as tgftgftgftgf, etc.) It has been applied to the actual construction and achieved good results. We have successfully applied it in the capacity expansion and reconstruction project of Urumqi Petrochemical.Lubao,Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.Section shape stainless steel pipe can be divided into round pipe and special-shaped pipe according to the section shape. Special shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes hexagonal tubes, octagonal tubes and various cross-section asymmetric tubes. Special shaped pipe is widely used in various structural parts, tools and mechanical parts. Compared with circular pipe, special-shaped pipe generally has large moment of inertia and section modulus, and has large bending and torsion resistance, which can greatly reduce the structural weight and save steel.The petrochemical industry, including the chemical fertilizer industry, has a great demand for stainless steel pipes. Stainless steel pipes are mainly used in this industry, including, , l, etc., with an outer diameter of about ￠ - ￠ and a wall thickness of about mm-mm (generally medium and low pressure transmission pipes with a specification of more than & phi; mm). The specific application fields are: furnace pipes, material transmission pipes, heat exchanger pipes, in which ferrite accounts for % - %. This dual phase structure is not easy to produce intergranular corrosion.　　— Common precipitation hardening stainless steel models, stainless steel coil, stainless steel belt and stainless steel pipe are safe and secure. They are usually also called -% Cr and % Ni.Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.production costs,CE--“ Code for design of cold formed stainless steel structural parts & rdquo; And & ldquo; jointly published by nidi and euro inox; Structural stainless steel design manual & rdquo; The design of structural parts for buildings with long service life and good integrity has been simplified.Stainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance, carbon steel pipes and plastic pipes.Austenitic stainless steel has good resistance to uniform corrosion, but there are still the following problems in local corrosion resistance: intergranular corrosion of austenitic stainless steel. Austenitic stainless steel will have intergranular corrosion when it is kept warm at ~ ℃ or cooled slowly. The higher the carbon content, the greater the tendency of intergranular corrosion. In addition, intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix, which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.

Stainless steel pipe, which was produced and used in China at the end of the s, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.Installation conditions,The surface resistance is less than mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.Since the invention of stainless steel at the beginning of this century, stainless steel has integrated the image of modern materials and the excellent reputation in architectural applications which makes its competitors envy. Stainless steel will not produce corrosion,HaimenlinnaOcr25Ni20 stainless steel plate, corrosion or wear. Stainless steel is also one of the metal materials with high strength. Because stainless steel has good corrosion resistance, it can keep the integrity of engineering design of structural components. Chromium containing stainless steel also integrates mechanical strength and high extensibility, which is easy to process and manufacture parts, and can meet the needs of architects and structural designers.Restate the quality of stainless steel pipe, such as stainless steel pipe, we promise & ldquo; chromium and nickel & rdquo; Penalty for false and provide quality inspection report and certificate of conformity.HaimenlinnaAustenitic stainless steel austenitic stainless steel is developed to overcome the lack of corrosion resistance and brittleness of martensitic stainless steel. The basic composition is crl% and Ni%, which is referred to as - steel for short. Its characteristic is that the carbon content is less than .%, and the single-phase austenite structure is obtained by the combination of Cr and Ni.Section shape stainless steel pipe can be divided into round pipe and special-shaped pipe according to the section shape. Special shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes, hexagonal tubes, octagonal tubes and various cross-section asymmetric tubes.
